Ok guys and gals have an update on the low compression, (125 psi) tore the top end open and you all were right not a purty sight. Found the cylinder and the piston scored on the exhaust side of both and where the power valves are there was a flat spot on the ring. Also found the needle valve from the throttle was in the 4 th position so I moved it to the third. Sending the cylinder out to get sleeved on Monday so won't have it back together for a week or so but I wanted to ask what anyone thought about who is the best company to go with for the new piston and gasket set? Also is there anything else I should/ can check while I have it torn down? Should I have the rebuild company do anything with the power valves? I will pull the pilot and main out later this week and update on the sizes so I can get feed back on what should be in it from stock since I'm going back to a 54mm setup like factory. I am in Indiana were its 20 one day and literally 70 the next day. More to come on the carburetor. I also wanted thank everyone for their help since I'm a newbie at this and you all are a plethora of knowledge so thanks the help. I'm going to attempt to add some pics so you al can learn/see from my pain (lol)-(money) again (lol). More to come.
