definitely a fuel pump issue, as andy said spec is 51psi +/- 1.


I had 51 while running and about 40 when key on power without running last week when i tested mine.  it shouldnt drop off right away either, mine held for a good bit while testing it.

you might be able to do a rebuild with the $65 kit from BRP otherwise a pump assembly is about $300-350.  I think rocky mountain had the cheapest oem pumps but never ended up buying one.

Check your plugs too while you are at it. $20 for plugs, make sure they are gapped properly. check your air filter and replace.  might as well do the oil in it too LOL
