Modern Vespa

The Leo Vince pipe finally arrived!

So I went and picked it up and got to work.

The breaker bar made short work of the exhaust bolts on the BV - didn't have one before and I have to say - this tool is invaluable!

Removal of the stock exhaust was simple enough. Then I partially installed the pipe - so I could get the muffler on there. The only issue I had was that the bolts included for the re-installation of the muffler with the adapter plate are too long for the BV - the pipe is the same one they make for the X8 250 - so I am guessing that these bolts (8mm x approx 65mm) are made for that installation - a quick trip to Lowes and I was back in business.

Overall - not much difference in sound - a little throatier and I definitely get some pops as I coast along with no throttle - but overall this is not really a loud pipe.

So, here are the pics

looks clean

Glad you tried these pipes and reported back. They look great and are you happy with the sound? Did you want something louder?

I was kind of on the fence when it came to volume. I was prepared for a loud pipe. I am rather pleased it doesn't sound like a 'harley-scoot'.

I am very pleased with the overall look and apparent quality of the pipe. The sound is a bit louder when starting out from a stop - but overall - not a large increase.

Do they make a fitament for a Vespa GTS?

The Piaggio part just rusts way too easily, and the aftermarket stuff I've seen so far just doesn't look right with the lines of the Vespa. That looks a bit better than the PM pipe.

Don't know how it works though...

They don't have any pipes for the GTS I've looked into it. There are some folks that are itching to mod this pipe to the GTS though. I would go that route but can't give up the scoot for the time required.

Very nice looking pipe! I think it makes your bike look great, Beale.

I would contact Leo Vince and see what they have to say. That's how I found out about this one.....

Nice job with really helpful photos. But where did you find the pipes? Leo Vince web site only lists the BV500 and BV200. Also, any improvement in performance?? Tks, Retired Ray

The Leo Vince pipe looks really nice. Maybe I can pick one up over winter and pop one on my BV200. I see that Motorsports has them on their website. Maybe the price will drop a bit more Is there any change in performance? I think the pipe for the BV200 comes with rollers too. Did yours come with rollers??

Don't really need to say this, but Leo Vince is coming out with a GTS pipe in AugSeptOctober. It'll most likely be the same price as the BV250 pipes and will probably have the same sound.

Is the sound more "tuned" than the stock pipe? Does it have more of a whine than a gurgle?

I called Leo Vince USA - asked and they gave me the part number - then I had my dealer order it.....

So you don't have to do any rejetting?

Not that I am aware of - I called Motorsport and they told me it wasn't required with this pipe........

does the BV250 have a lamba sensor??

i think it does, its basically the same engine as the gts but with a carb bolted on top instead of the injection.

Not really sure what that is.......

it's a wired probe/sensor about the size of a spark plug that screws into the exhaust header pipe, it measures the exhaust gases so the fuel air mixture can be corrected

Then that would be a no for the BV250. The pipe came with a plug for that hole - I am guessing the X8 has one due to the fact that the hole is there and they are the same pipe.....

the plug will probably be there for another model. gt200? or maybe a runner 200?

scorpion drilled a hole int he header pipe for the lambda sensor on the gts exhaust.

it was basically a modified gt200 exhaust.

Maybe that's why there have been so many problems with the Scorpion exhausts?!

That is the main problem with a carb you have to manualy adjust the fuel air mixture. I read somewhere (maybe in the owners manual) that the bv250 runs a little lean for the cats. On my last bike a gt250 comet I took the baffles
out of the exhaust then I just adjusted the needle valve to the next richest setting. It ran great and I didn't have to rejet. Some needle valves have different slots in them to fine tune the air fuel mixture. All you have to do take
out the needle and look at it. there will be a washer in a slot it there is only one slot there is not much you can do. My gt250 had three I just moved the washer to the next slot closer to the sharp end of the needle.
