Well my first ms660 I've had ruffly ten tanks through it and the cylinder and piston are ugly although it was still running really good but I thought I would tare it down and put a new cylinder and piston in it and I've got a full tank run through it and the results are looking way better I took the muffler cover off and piston and cylinder look like they should and should be fine now My second ms660 is still lacking a lot of parts before it runs but I'm still thinking about it and I my chang some things on it just because Lol like let's say maybe big bore LolHow many tanks have you got through your last build,?
