main bearing?

[VictorK]

my left pipe has been vibrating when I rev it up, at first I thought it was hitting the boost bottle(worthless I know), after checking it out I pulled the stator cover off to learn the main bearing has play when I grab the mag and move it. can a worn main bearing cause it to break up a little? Im gonna take it out and replace the bearings, have the crank welded and add a cool head.

i'm sure a bad seal there will cause something..............

Put in a new 4mil crank

I did a leak down test a few weeks ago and it was fine. I have a extra stock crank with very tight connecting rods, I think Im gonna have it welded by a site sponsor. I obviously need new main bearings, im adding a cool head also, and mint welded crank. once I have it ported I plan on ending up at about 70hp, would a good stock/welded crank hold up well with nearly 70hp?

That would hold up with NO problem.
