Brilliant piece. Thank you for the effort.

Does anybody care to advise me with regard to slider weights for my 500 if I even have a choice with the Jcosta. I am after acceleration above all else, so what can I expect?
The JCosta kit has weights and, yes, JCosta do a variety. I believe the standard for the 500 kit is around 25g per weight? JCosta do quite a lot of different weights around that.

When I got my 400 kit is had the wrong bell but we didn't discover that until I had tried lighter weights (16g down from standard 23g).

The acceleration with the 16g ones we better, but not always, due to 'bad behavior: sometimes the revs would shoot up to 7500 but then drop back to 6000 implying that it was doing a lot of revving but not actually transferring additional power until it had 'settled down'.

I went back to the original weights and behaviour is much better, but I believe the pickup is not as good.

Next service I'm going to try mixing in pairs of the 16g weights to get an 'in between' setup that will hopefully get the best acceleration but still behave well.

As a side note: my main reason for getting the JCosta kit was to smooth out and perhaps improve a little in the take-off and low revs. This did seem to work, but the last couple of weeks I have noticed that the roughness, shuddering and power-lulls have returned Except after a good long stretch of high speed - then the first 2 or 3 take-offs are great.

Weird and not necessarily the JCosta kit, but it feels very familiar - just like when I had the wrong bell in place - I'm wondering if the replacement bell I got was a re-pressing that is now moving back to it's original wrong-for-the-400-engine shape.

I'll keep you informed...

More info from the weekend. The problem I was associating with the JCosta may be completely unrelated!

Changing the plug during the service it appears the centre contact (not one of the pair hooked over it) was gone! That's about 1.5mm or 1mm diameter tungsten (or whatever) that has come off, disappeared into the cylinder and then, apparently, shot out of a valve.

Now. The likelihood of that happening is apparently very low. More likely it has embedded itself in the head (or whatever). We had a look around with a probey-camera thing, and there is no evidence of damage, though we couldn't see everywhere.

Anyway - something else that was clear is that the air filter is having lots of oil blown into it - there was lots in there and I only checked it a week or two previously.

On clearing out all the oil from the filter and having a good clean around that part of the system, the take-offs and low-speed characteristics are much improved and, importantly, are much better than with the original variator.

We decided not to touch the variator at all and things still seem good. I'll keep an eye on the oil and let you know at the end of the week whether it's still good.

I'm happy to report that the JCosta 400 kit may well be a winner after all. I will definitely be happy to have got it wrong

Absolutely fantastic,

I pulled my transmission belt and checked the rollers this past week-end using this thread.

Thanks

Fuzzy's "washer mod"
Given recent developments with Fuzzy's "washer mod", just wanted to bump this thread up to others curious where it is exactly that this 2nd washer is to be installed.

I didn't get it wrong. My engine problem fixed, exactly the same problem occurs.

On taking out the JCosta recently, the inner brass ring is worn very badly by the washer as with other people's.

Can we say "design flaw"?

Needless to say it's out now

Elementalist the Dr Pully weights and extra washer on my 400 is a similar improvement to the J-Costa on my 250. Might be worth a try on your 250.

Also at least 2 members with a 250 have put an extra washer in with the J-Costa to make up for the wear in the bushing. (I am one of those and that is the way I sold it to Chibbs) Have not heard if either kept wearing to the point of needing a 3rd washer. 250 washer is 1 mm thick.

The J-Costa was a really sweet improvement to the 250, too bad they won't accept and correct the problem. Mine was replaced by them with a comment they had some with bad material in the bushing. but the second one did the same thing. Never heard back about the second one when I reported it did the same thing.

Elementalist I read your posts in the general forum and realized you are talking about a 400 not 250. Sorry I didn't look at your Avtar information properly.

Same thing though on trying the washer and Dr. Pulley weights.

You may want to post his as a new thread in this forum so others are more likely to see the warning. 500 owners need to watch out too as it is the same part from J-Costa, just different weights.

Some pictures of the worn part would also help. Some comments on other threads thought 400/500 J-Costa were made different so would not suffer the problem.

Thanks for sharing. At least you didn't have broken belt and lost oil pan gasket suffered on some 250s.

The 400 and 500 J Costa variators are NOT the same, according to the UK distributor at least.

My mistake.
Pretty sure I read that in another post or perhaps confusion as the OEM variators are the same. (Maybe I am wrong there too?)

I think you're right about the OEM variators. Different part numbers for the complete assembly in the catalogues, but only because the weights are different.

Actually the same might be true for the J Costa, as the bell housings are the same for both.

Jim,
After reading your reply I looked back at Joe's pictures earlier in this post. His J-Costa looks like an exposed bronze insert similar to the 250 ones. I seem to recall you stating the 500 does not have an insert exposed to the washer?

Joe's install.

The 400 and 500 are the same.... mostly anyway. The difference in J Costa part numbers is only because of the pin weight.... the 400 uses a slightly lighter pin weight than what the 500 does. Other than that, everything else is the same.

That's not my undersanding Matt. I actually was sent the 500 JCosta bell first and it doesn't work well. The 400 one I was sent when you compare directly has the center slightly more indented - maybe 1mm - but that, as we know, is more than enough to make a gearing difference.

Can someone else confirm that the 400 JCosta bell part does have a brass insert? Or have I maybe been given the wrong one again?!

That would be really quite... upsetting...

Matt, did J-Costa give you any input on the 250 one I sent back to you in the fall with the wear on the bushing? The replacement you sent had the same problem but is still on the MP3 with washers being added to offset wear.

elementalist.... I will check measurements when I get back in the shop this week and let you know.

Fuzzy.... J Costa has an issue with Piaggio in general as they have not consistently made a 250cc variator over the years. On some 250 models, there is virtually no wear and no issues and on others... well, you already know. They are doing their best to determine which models use which version but for now, the brass bushing is considering a wear item.

About 6 slightly different variators that I know of on the 250 Quasars - all J Costa needs to do is get an example of each. And the 250ie engines are different again...

I have been wondering if there was something that could be done to improve the "jittery" take-offs on my 400... mostly when riding 2-up. It sounds like this would be a good upgrade to consider, but now I am not so sure with the posters that are describing early wear.

Overall, do they wear out faster, or about the same as the oem? Also, the link to scootertrap.com shows that the Dr. Pulley sliding roller weights are no longer available. I believe that these are related but different... am I correct? Which would be the best answer for the low speed jittering?

Thanks again for your patience with this newbie and your help...

After several months of expensive and potentially dangerous annoyance, weirdness and wildly varying performance I'm afraid I can only recommend not risking the JCosta variator especially for the 400.

Perhaps it's difficult to match variator and engine given Piaggio seems to have slightly varied the engines even within the same plate/year on the same model it's pretty awful that JCosta didn't seem to know this before making their variator and then, when/if they do work it out don't reliably provide guidance on which to use where and if they can't provide guidance on how to get the right one, then they shouldn't be selling them!

It is a shame, because when the variator did work, it worked well, but unfortunately that was about 5% of the time and the rest of the time you risk mid-traffic stalls and take-off power lulls when you don't expect it.

Wonder why the 400 owners here aren't having any issues with the J Costa. I have 2 local guys that absolutely love them and have reported no irregular wear. I'm wondering if you received a bad or defective setup.

Matt, if the 400 model you sell is the same as 500 with different weights then that is not what the some of the Europeans here have. Look back at Joe's pictures. The vairator has the bronze buching exposded to the washer. The 500 variator, if I understand correctly, doesn't.

There is no denying many on MV (both on general and MP3 forums) have had the problem on 250 model and now at least one on 400 model that looks like the same design. J-Costa needs to step in and help. The cost of my 250 J-Costa variator was a fraction of the cost of the problems it caused.

Also the type of riding and distance will impact the problem showing up. It only wears at WOT and high speed with the weights fully extended. Mine too 4,000 miles of that to show a problem. Someone riding mostly in town and or with a less heavy hand on the throttle will take much longer.

I strongly believe J-Costa has a better idea than stock but this wear issue needs to be solved.

I agree with Fuzzy. My 500 variator looks entirely different to the 400 one. The aluminum of the inner variator pulley extends right down to the sliding sleeve - the phosphor-bronze bush does not peek out, and cannot rub against anything else.

Can you take sample photos of your supplied stock? Especially of 625 and 626...

I know I did post a photo of my inner driving pulley somewhere, but cannot find it right now.

Not True... Please see below email from Xavier Pallarès from J.COSTA factory sent to me on 06th of October 2009
Dear Joe, first of all thanks for trusting us.

Let try to explain you. At the beginning of 2008 Piaggio with Master engine(400&500) decides to change the length of the belt but using the same p/n, to solve that we needed to change the bell housing. Now Piaggio has change again to the old size, so now we need to change again the bell housing. This one is compatible with both belt sizes.

Hoping it will help you to understand.

I send you by post the new bell housing

Please note that I own 2009 MP3 400ie... so be aware!

J Costa (or similar) Installation
With installing new variator weights or rollers etc does anyone know if it is possible to do the job without the correct "Variator holding tool" ?
Is there an alternative method that will work without causing damage?
Any advice welcome.

Also, how often are the variator rollers or balls and belt changed, is it done automatically at a particular service?

Thanks,
(Johndunoon)

Many do it with just an impact wrench but there is risk of problems with not getting torque correct. You can find some old threads with arguments on the need for a torque wrench vs impact for this task. The Buzzetti tool is inexpensive and works well. The Piaggio tool is expensive and in my opinion harder to use.

woo!
awesome advice here, especially:

- harbor freight
- impact wrench
- torque wrench
- impact wrench sockets

- buzzetti variator tool
- magnetic screwdriver ( not only for screws but also for removing washers )
- 'screwdriver trick' with the clutch
- torque values

Prior to this the most maintenance I've ever done on a scoot was changing the oil on my Elite 150D ( um, 10+ years ago ).

Honestly everything would have been over and done with had I not hit one major snag. After taking all the screws out of the transmission cover the damned thing wouldn't budge. i brought up this post and kept trying to find where it said 'a miracle happens' right before the shot with the transmission cover off. no luck. i triple checked all bolts were out. still no movement. after trying some gentle prying with the screw drivers i took a couple whacks at it with a 5lb sledge damped by a wood block, nothing. eventually i found a small prybar in the garage and started working it around the outside. i did manage to get a small gap. after about 15 minutes of this it finally let go and i was ridiculously happy when it did. looks like the bearing in the transmission cover had rusted to the driven pulley spindle. I installed the dr. pulleys, fuzzy washer and new belt with no issue. I only needed the impact wrench to get the variator bolt off( thankfully as i had a sleeping toddler upstairs). i sanded off a bit of rust from both the transmission cover bearing and the driven pulley spindle and lightly greased them. after all that reassembly was a snap.

After all that the only real casualty I noticed was that 'washer #1' on the driven pulley side of things was notably absent. I don't recall pulling it off. Anyone know where i can pick up a replacement?

EDIT: NM, checked on athens scooter and it doesn't show up for the 400 so i'm guessing i'm ok: http://www.athensscooterco.com/eshopprod_cat_4797-48548-48374_product_602986.109_DRIVEN_PULLEY_WITH_CLUTCH.htm

thanks again for the fantastic write up.

it's like a whole new scoot after the pulley and fuzzy washer, wow!

I only needed the impact wrench to get the variator bolt off( thankfully as i had a sleeping toddler upstairs). i sanded off a bit of rust from both the transmission cover bearing and the driven pulley spindle and lightly greased them. after all that reassembly was a snap.

After all that the only real casualty I noticed was that 'washer #1' on the driven pulley side of things was notably absent. I don't recall pulling it off. Anyone know where i can pick up a replacement?

EDIT: NM, checked on athens scooter and it doesn't show up for the 400 so i'm guessing i'm ok: http://www.athensscooterco.com/eshopprod_cat_4797-48548-48374_product_602986.109_DRIVEN_PULLEY_WITH_CLUTCH.htm

thanks again for the fantastic write up.

it's like a whole new scoot after the pulley and fuzzy washer, wow!
your misssing item # 17 washer which is the one Joe posted as the #1 at the beginning of this thread.
This washer is important as it gives the other spring washer something to press against when torqued down and not damage the vari.

Advice so you don't lose washers or get them out of order. I put the washers in a stack as they are removed, then run a tie wrap through them to keep them in order and from getting lost.

awesome advice here, especially:

- harbor freight
- impact wrench
- torque wrench
- impact wrench sockets

- buzzetti variator tool
- magnetic screwdriver ( not only for screws but also for removing washers )
- 'screwdriver trick' with the clutch
- torque values

Prior to this the most maintenance I've ever done on a scoot was changing the oil on my Elite 150D ( um, 10+ years ago ).

Honestly everything would have been over and done with had I not hit one major snag.

Dirt, Now that you are up have a cup of coffee and re-read.

monkeywobble stated it was the "driven pulley" washer #1. (Joe has two different pictures with washers numbered.) This would be the washer that goes between the clutch and the bearing in the housing. There was a thread a while back where someone broke the housing getting the washers in wrong. If you are missing I would make it a priority to get it right. If not there to start with could have something to do with not wanting to come apart. It may have had a bind on the housing from being pulled in too far with the washer gone. Probably a bigger issue than missing the washer against the variator.

TIA
