so we just bought a project/fixer upper…a 96 xpress 400L. it’s a pretty solid bike but there were a few issues, most of which i’ve completed. i’ve done some research on here about bubbling into the coolant overflow when it’s running, and i’ve seen answers ranging from new radiator cap, to "that’s normal in hot conditions"…i thought head gasket/or needs top end work, but i did a compression test and it was 113psi, and it calls for 115. it’s smoking white off and on, which also tells me coolant into combustion chamber. i guess the liquid cooled 2 strokes are pretty new to me. always had air foolers..but could it just be the head gasket?? seeing as how compression is still almost spec, but i’m getting coolant into the cylinder? still cranks first or second pull every time and will run great until it gets hot. (need new electric fan motor)

thanks in advance
