Just another new guy!!!

Now that you've clarified the details of your build, I don't think anyone has a problem with it, we just get concerned (not without reason) when people start talking about bolting a massive engine onto a tiny go kart...

As for bearings, it has been my experience that OEM parts are usually a lot more expensive than a generic aftermarket replacement; case in point, a few months ago, I priced rear wheel bearings for my car; Toyota wanted over $100, local bearing shop wanted less than half (around $45 IIRC) for an identical item...

From what I understand, the only part of the bike you'll be using is the engine, everything else will be kart/buggy related, in which case, your local bearing shop should have every possible bearing you will need at a reasonable price (in some cases, the hangers will cost more than the bearing); just make sure you buy Japanese, NOT Chinese!

Right on. I actually am seriously trying to get myself into position to get a roller mini sprint since I can be at a home track without traveling every weekend. Believe it or not, although we have a track here and several others not far away, it has been very slim pickings and hard to find rollers for sale in lower michigan. I have no idea why. I've been told that they are everywhere in Virginia for dirt cheap. As for building this one I'm doing it simply because I love building any and everything that brings some satisfaction. It's just in my blood like probably most of you. I recently fabled up the turbo plenum for one of the bikes. Still have some sensor ports to drill, intake and what not, but ****, it's my first turbo build so we shall see how it turns out.
