If I was to replace the LML engine in my VBB completely what's the latest or most reliable type that will fit directly in without too much hassle? and how difficult are they to get hold of?

LML engines are pretty easy to get hold of, although they arent the best

I think it would be a pretty straight foward swap

I put an LML 150 in my otherwise underpowered VNB. The conversion was a snap, though you need to get the kit to convert to 8 inch wheels. They used to sell them on SW. Pretty simple switchout, but you will probably have to grind down the cases just a smidge to get clearance on the rear hub. Nothing major. Check the forum here; there are others who have done it and helped me out immensely (I think it was Killo's post).

Also, be aware that, unless you get the 8 inch LML, which I don't think you can find anymore, the gearing will be off. It does not bother me that much since 45-50 is all I need to do on 8-inch wheels, though you do need to watch your RPMs, particularly in the break-in period. After getting through the break-in, I put a performance pipe, which helped with my revs but brought about some potential clearance issues. We'll see.

PM me if you have any questions.

Just realized that you may have already set this thing up for an LML and are now looking for a replacement.

the "latest" would be an LML. The "latest + most reliable" would be a PX200 motor. it'll cost you $2000.

A brand new crate PX200 would cost closer to $2800.

PX200 sounds tempting
I'll keep my eyes and ears out for a PX200 in Aus to save on shipping.
Probably quite sought after so i don't know how rare they are.
Cheers for the info

What's the problem with the LML? Is it unreliable?

Unless you can get a 200 cheap (unlikely in Aus unless you know someone) then just put a decent crank and top end in your case. My mate's LML will do 110 km/h (GPS) with Polini 177 28mm PHBH and Mazz crank.

nah not really starts easy and runs ok but it's done some k's by the looks of things and the gear selection is pretty dodgy (but i've had advice on other posts on what to try to resolve that)
i just thought i'd take a look at the options and replacing it with a newer engine might be easier that spending lots of time and money getting this one up to scratch and even then it might not be as i want it.
I'll try rebuilding the clutch first to see if this helps.
Mine goes up to 100km/h ok so perhaps i should just get it sorted out.
Shame that vintage scoot mechanics are few and far between. I cant seem find any on the Gold Coast.

Don't know har far Brisbane is from the Gold Coast but there's this guy -
http://www.kickstartscooters.com/pageDisplay.php?module=page&pid=1

Also there's an old guy on the GC somewhere by the name of Ross, supposedly he's a 'legend'. I bookmarked the page but it's gone now. However if you contact these guys (Borderline Nuisance Scooter Club) they should be able to steer you in the right direction. One of their members Philthy spoke well of him on my club forum so he should be known to them. Let's know how it turns out.

Edit: Forgot to add the link! Sorry.

LML is a decent.

If you have problems with it, fix it.

You can replace bad parts with standard, high quality stuff and you'll still come out ahead money wise.

They've started selling PX150s in Aus recently(which is odd because in all the previous incarnations of the P-PX it was only 125s & 200s they brought here), too new for a second hand motor to come up for sale, I doubt a crate PX150 motor would be any cheaper than a PX200 one.

How soon do you want a new engine? I have a 10,000km PX200 engine I'll be offloading, probably this year but I can't really say it's likely to be any time soon, I'm building a kitted engine from a brand new case.

it's not urgent now as i have found an aftermarket clutch kit to install.
Let me know when you want to offload and I'll see if it suits my timing as i am interested.

Do you have an idea of how much you'll want for it as yet?

Not sure yet, maybe $300-$400, So far it hasn't run since 2004 but there was nothing known to be wrong with it last time it did run.

I got a used LML motor from India for $200 total. It works great in my VNB. I have the latest post06 red cdi. It took some work figuring out the wiring but I LOVE IT now that it is running great. I have a 10 inch wheel on back now and an 8 inch wheel on front.

The 10 inch wheel, rejetting, and an expansion chamber...oh and the 12V lighting oh and the CDI make it a pleasure to ride.
