Hi guys, been a while. My 95 400 Scrambler still is not running well. It has decent power cold, but barely runs once it gets hot. Anyone know what the cylinder compression is supposed to be? Mine maxes out at 120, and I'm sure it should be higher. If that is a good compression, are there any other heat related ideas that may cause it to run funny. I originally thought it was the RSS as it portrayed many of the same symptoms, but after a little searching found that it had already been "bypassed."

 

yea 120 psi or better would be best. you should check it w/ it cold and wot to get best results. does that have reeds? if so are they in good shape, not broke or cracked. doesnt over heat right? just a couple of idears.

 

yes the problem is heat related, it runs terrible once hot. Checked th coil and it's ok, just plain out of ideas.
