When you say remove both plugs, what do you mean by that.. as far as when doing a compression test? Dont you need to have one of the plugs in while you do a compression test? Elevation where I live is around 1300+ ft just outside of Pittsburgh, PA.. actually maybe alittle higher around 1400-1450. So do you think this may effect the compression and explain why its a bit low?

Yeah, I was going to run it and then do a compression test but it was getting late. Yes, just changing the gearcase oil. Is it normal to have a grey looking gearcase oil? Doesn't look like water has been in there but just wondering.

I just got a 2000 Banshee the other day, engine is mostly stock with stock pipes except for a booster bottle. I was told the engine was rebuilt a little over a year ago and is still on the standard bore. Since it was last rebuilt, he claimed it only had no more than 40-50 hours on the top end. I did a cold compression test just about 5 minutes ago with a WOT and about 20 kicks... I was only getting a compression reading in both cylinders between 105 and 110. I pulled 1 spark plug at a time and thats my reading. I'm a little concerned about that number being a little low. I'm guessing stock is about 125-130psi? It runs very well and starts first kick everytime. However, I have not really had a chance to ride it at all since I'm redoing bushings and bearings throughout, changing oil, etc. But it definely starts and runs great. Should I be concerned about the compression at this point? There is an upcoming ride in 2 weeks that I have been planning on going to for the whole weekend. Probably ride between 10-14 hours. Think I will be good as far as compression?
