I know Stuarttiainen built his Allstate up in this format, and White Lion Matt from Atlanta has chimed in about doing this kind of build.

Has anybody else had experience with a P200 lump in a VNB. Specificly what the ride is like if you do the 8% up-gear? i.e. how close does it accelerate compared to a stock P200E? Does it err on the side of being torqy, or is it pretty restrained?

I'm planning a scoot like this, but want to see if there are any roadblocks that I can avoid that others may have run into. So if you have ridden or built a bike like this please drop a comment.

Thanks!



edit: To be clear, I mean how does it drive if you do the up-gear. I know that if you just put the engine in with 8" wheels it will do wheelies all day every day and that it will cap the top speed to about 50mph.

Following this thread as a VNB with a P200 is the build I'm collecting parts for now.

I love the idea of rapid acceleration with a 50mph or so top end. (In fact that's pretty much exactly what I'm hoping for.)

Sweet. I can't wait to see your build. Hopefully someone has some experience with this combo. I was hoping to keep the cruising speed more comparable to the P200E that is my current daily, so I'm more likely to do the gear adjustment. I've got a chronic fear of seizing an engine (again) so riding a high revving P engine every day sounds a bit too stressful for my taste. That said, it sounds like alot of fun at red lights!

I have a VBB200 without the regearing though. Iím still breaking it in, so not much to tell, but like the way it rides for the moment.
