Ok i just bought A 1995 Honda fourtrax for 250 . Now i have spark and fuel and everything is rotating now i scoped the cylinder and the piston is dead. what i need to know can i leave the motor on the bike to repair piston and if so how long will it take me to do so

 

Both 300 and 250 canbe done still mounted in frame! How Long!!!! Well that depends on how familar you are with taking down this type engine! Me bout four hour down and back together!!!!! I guess an on normal type basis prolly 6 hour 3 to tear down and 3 to put back together counting clean up head and gaskets.......

 

ok cool well i better get started then i have the manual and i should be fine thanks again
