Technical / New YZ Project

Well, the cases are all apart, all the gears are there, but as I was inspecting everything I found that the transmission bearings were not the greatest, and that there was pieces of rust in many parts of the cases. Is it okay to put my cases in a parts washer if I can find one? How do I know if the bearings are okay? This is going to be a little more pricey than I thought already because I can not find any company that makes aftermarket transmission bearings, only crankshaft bearings. I am happy to say that things are coming along nicely, but there are definitely a few frustrations along the way. I guess there always will be when you rebuild a dirt bike.

Yeah, I would first check for spark, if you are finding spark, then bomb start it. Get a friend to push you down your street and pop the bike into first or second. If that does not work, and you for sure have spark, then check to see that the cylinder is getting fuel. Rebuild the carb maybe, it isn't too expensive. Last thing I would do, or it could be the first is do a compression check. If you have a brand new piston and ring, then it is likely a worn out cylinder.

Oh! Also, how do you know if you need a new head, and where could I get one repaired, or even modified?

Well, my parts came in, and it was like Christmas! Unfortunately I found that I have a few parts I still need to get, if anyone has YZ parts they would like to sell, let me know. Anyways, here are some pictures of the goodies.

Or do you guys think that I should order the tools necessary to build the seized crank that I already have?

So here comes the fun part, ordering parts! Woohoo! It is going to be a big bill, but I am doing this so that I can learn about motorcycle mechanics. However I really need your guys' help. I am trying to decide between a Hot Rods crank and a Wiseco crank. I had previously installed a Hot Rods crank professionally and it shredded to pieces after about 6 hours in my Honda, so I am very hesitant to go Hot Rods again. However I have heard many good things about Hot Rods, and that maybe I just had bad luck. What do you guys think?

Pressure washer isn't needed

The bike is all disassembled now, frame and subframe are getting ready to be sandblasted, then will be painted. Silencer has been painted, I was surprised as this was one of very few parts that was in good condition. Just waiting to go to the Montana border to pick up parts, then I can start re-assembling
