kicks azz. You should start selling them.

I told you guys that Nic had an awesome mod up his sleave!:clap: I couldn't wait to see this cover and got to see it in person this afternoon. It is killer!

Nic just got this 026 so we went to tune it with a stock cover for a baseline. The saw wouldn't hardly run. I pulled a compression check and it was struggling to make 120 PSI. I had already looked at the P&C and they looked great. I pulled the jug since we wanted to clean the carbon out anyway. The rings are SHOT. The top ring had a gap of .037" and the bottom a gap of .027". No wonder it ran like crap! We're going to put a new piston in it and a carb kit. Should be good as new. Can't wait to get that new muffler cover on there and tuned in.

So what's a mod like this worth? We talked about me selling these as an option on my ported saws. What do you think?
