nope no smoke, been using 10w30 full synthetic oil Mobil one.yea im not going to put no more money in it after this got the head milled for 10.00 and head gasket for 3.00. so hopefully good old girl last all summer than ill tear it all about.rebuild it all the way up.
847- yea i got a few extra blocks and parts got some spares to learn more on how these motors work.

I don't use head gaskets anymore. More than enough clearance in my case(s).

really how come what do you use i mean don't the head leak .is that because you are messing with more 2 cycle motors

See post #42 this thread:http://www.diygokarts.com/vb/showthread.php?p=10176#post10176
Head gaskets can be eliminated on 4 cycles also, as long as there is enough clearance. This mod can also eliminate the need for milling head.
Proper head sealing is more important on 2 cycles than 4 cycles. I don't mess with them...I make them better performers.

No problems and, yes, I run them very hard.

I would not use anything other than what I pictured. Good high temperature stuff.
Please remember that CLEARANCES MUST BE CHECKED before doing this mod.

yea, if i were to do it, i'd do it after i take the head back to the jack asses job to get the valves a little head room. that is if i have enough material.
