2003 and later compression

[rruser]

I know a few people are going to kill me for this... but just go along with it for a min.

Can someone with a 2003 or newer Warrior(or any Raptor 350) go out to their garage/shed and tell me what they get for a compression test? I don't want to know what the book says or what it should be. I want to know what numbers you get from your own test. Tested at WOT on a good battery. opcorn:


Thanks.

Thanks YAMAHAAULER. I asked this question a few months back, but too many people just quoted the manual.. or they lliked to say "should be xxx"

I get the same readings on any 2xxx year motor I have worked on. My factory sealed 2003 did 153. My buddy's 89 with a refreshed 2003 top end showed 155. The factory manual says 12x PSI max. I think the raptor 350 manual even says it... and a lot of people say they have 120.. but I have always seen 150 out rebuilt 350s.

If you have better than average compression don't fret and be happy.
