This is actually my second post. I couldn't resist a previous post on the boygofast thread. After hours of researching your site, I ended up with the 4 cycle kit from 'boygofast' on eBay. I have a 14 year old mountain bike that was the basis for my project. The kit was a straight install for this bike. It looks like China must be overrun with old mountain bikes. Just about finished with no problems. I'm having lots of fun with it and it probably will always be a work in progress. It really is interesting to see and read about everyone elses projects. I'll be posting pictures in the gallery soon...
