UGH!!! Serious frustration! I keep having head bolts come lose, then I over tighten them and the threads on the crank case pull out!

Love the build! I always wanted one of the geared Genisis bikes but, I have alot sunk into my Onyx now that I haven't made the switch. As far as the piston modifications for the RSE reed valve I'm in the "should be done" camp, I cant offer any tangible facts. Only perceived performance. worst case scenario is you need a new 5 to 10 dollar part haha.

I spray one coat of silver grill paint on the threads for the crank case side of the studs to keep them from backing out on me, only on the ones that give me trouble. Ive had pretty good success with Helicoils for stripped out parts if it gets to that point and you dont want to replace your crankcase it might be your best bet.

hope you dont mind if I share some Genisis love in your thread here:

Hey thanks for the reply! Your bike looks AWESOME! Thanks for sharing, I really like seeing other people's as it gives me ideas for mine! So my crank case came in the mail but my Jack shaft was seized in the bearings and I had to cut through the bracket to get the motor out. Waiting on a new one from sbp now. I have 4 extra pistons, so I think I can afford to drill into one of them, haha. (I like having extra parts, I probably have enough parts lying around to build two complete bikes with another one almost all the way built) As far as getting your onix shift worthy, couldn't you install a free wheel, or is there not enough room in the frame? You would have to rig up some kind of connection for the derailer and wire, but it seems like it would be doable? Or even the three speed internal hubs they have? I've read people like those a lot more actually.

Oh, also, does anyone know a good source for bicycle fairings? I've been looking around but can't really seem to find what I'm looking for. I'd like to build a bike that looks like a motorcycle, like it could fool people who didn't look close. Not the genesis of course!

I think Wald makes decent steel 26 inch cruiser bicycle fenders. If thats what you were referring to. Otherwise if you dont mind spending the money fenders from Worksman bicycles would probably be the strongest bicycle fenders I can think of.

I thought about putting a 3 speed hub on my onyx with the shift kit but I'd have to get new wheels. If I went that far then I wanted disc brakes too, when I priced the upgrades out as a whole it came out to about 4 to 500 bucks I think. Which I couldn't justify because I could get a Fito MODENA GT-2 with disc brakes and 7speed rear hub included for 300. Maybe this spring ill weigh the pros n cons again.

Yeah, I guess when you weigh in everything else you'd have to add to it, makes it a little harder. I got the Genesis at Wal-Mart for $180, but I had to put a different fork on the front (suspension) so that I could have shocks and a disc brake. Now that I have the shift kit set-up, I've been thinking about a rear disc brake! But I have a couple other builds I want to do first. I really really REALLY want to build a Fat Tire motorized bicycle next! I just got my bracket in the mail from SBP, so I will be in the garage working this weekend on the Genesis rebuild.
