Snowmobiling blues...

Some years back, I was going to build a Yamaha Phazer II. I wanted that fan cooled 485 cc to surprise a few 500 & 600 liquids. I ordered a AAEN pipe, jetted and put a spring kit in the clutch....… In my playing around, I opened the silencer box and found more power... and a burned hole in a piston. LOL

Replaced the piston, sold the sled in original form. I ran across that pipe the other day digging for parts to use against jab...
