Ok So I just got done rebuilding my brand new baby. (Pics Coming Soon btw) My list of mods is below in the signature. My question is should I run the stock recomended 20:1 Fuel mixture or the 32:1 that EVERYBODY and thier mother seem to be running. I am planning on mixing half race fuel and half 93 octane along with it. I just reeeeeaaaaalllly dont want to be tearing apart the top end all the time. I am going to be doing plenty of racing and trail riding so. . . Any help and input would be wonderful.

Thank you,
Nic

 

I mix mine 44:1 MC1 with av gas in my quadzilla and LT250R never have had a problem aren't you at your last bore with that cylinder? I have a ported '92 cyl that was 80 over and had problems with it

 

32:1 is fine with modern 2 stroke oils. The 20:1 recommendation is on the conservative side.

 

Yea unfortuneatly I am on my last bore with this sleeve. That is what it was at when I bought it. So I am trying to stay away from having to re-sleeve it for as long as humanly possible. I am planning on running some klotz in mine. Hoping to have minimal to no problems at all. What kinda problems did you have with yours? I had my entire motor professionally completely taken apart and re-done and looked over by a guy I really trust. New gaskets, new bearings, new seals, everything was looked at the whole 9 yards.

 

problem was finding a head gasket for 80 over piston I think my squish was too tight lost 2 pistons before I replaced with a 20 over jug that I got on e bay I even ran that used piston it came with over a year till I went 40 over with new piston
