I have a 170 dynojet, 42 pilot jet, 3 1/2 turns out, is taking the lid off worth it. It’s pretty dusty lately. I have a outerwear also. Is there a lot more power.

I know there’s a billion threads on jetting but I kind of have a unique situation. I jetted my carb for my 426 bore, well I recently switched to a std 85mm bore, best decision ever runs awesome now. But anyways I have a 170 DYNOJET in the main jet and a std 38 pilot ket( I’m irdering a 42, heard great things about it). The air/fuel screw is 3 1/2 turns out. When I hit the throttle really quick, just like a blip it doesn’t respond it just kinda bogs a little. Any suggestions. I have a whole dynojet assortment so any sizes you think are good please tell me.

Should I use 10-40 or 20-50. I have an aftermarket cam and some people say run 20-50 with those. I’m in New England so it is 80 degrees domedays and 65 the next day. Also I want to use conventional, and any brands that are good?

my 400ex has 18in tires on the rear, and 22in front tires, which one is different from stock. The front looks weird because there much bigger than the rears.

Anyone have any tricks on compressing the rings into the cylinder. I tried using aluminum flashing but it didn’t work, cracked the sleeve. When I get the new one, is there a trick to this. I bought a 4in ting compressor but I don’t see had I would be able to use it. I bent the oil rings a couple times doing this because of the taper at the end of the sleeve. Also it’s a stock 85mm bore.

I’ve tried the two nuts against each other and heating it up but my studs won’t loosen on my 400ex. Any other tricks?

does anybody know how to loosen the two big odd-shaped nuts for the spring on the shock? I need to adjust it. and how would you tighten back up?

Does anyone know to to remove the 4 head studs, I need a new cylinder, they are not rusted that I know of. I have one out only because the threads were stripped in the cylinder.

Thanks
