Well everyone I got the motor put in the bike. I finnally got it to start took long enough smoke a flying out of the exhaust but it finally cleared out. The first thing I noticed is the quieter motor noise .
Today I took it for a hour or so ride at the dunes, it was cold and windy and alittle misty. I got the flag on went to start it, it took about 4 stabs with the starter button, I let it warm up, I stabbed it in gear went to take off it stalled and refused to start for awhile, I say a good 3 mins, then it started.
Performance- I noticed alot of power increase with top end on my 2mm stroker. The power delivery was smoothe, not hard hitting the way it was before, credit goes to a change in the mapping.
All in all I belive this z400 bearing is the way to go, with timbos crank,rod and pin. So far 3 hours of use not problems yet.
thanks again timbo

Get a little carried away with the assembly lube bknight. LOL
I usually just get fireballs out the exhaust . There pretty.
I pulled a new ATK crank apart and allthough it still had the same bearing in it a different coating was applied to the cage. Kind of makes me wonder if the crank manufacturer figured they had a problem and was trying to do something about it.

Here is a crank someone sent me. It has a very small crack eminating from the center of the web to about a quarter inch into the thrust surface that the rod slides against. Im not sure if this crank half is usable or not . I will let my rebuilder decide. This is an extreme close up. I blackened out the rest of the surface and took the picture through a magnifying glass at 5 power on my camera. It looks like the whole surface has a slight degree of rough cracking. It should be glassy smooth. Any one else seen this before?
