rite first hello to all at tsm, always been into two wheels from push bike to the barely safe ie bog seats
to motorcross bikes. had a good selection of toys until sum thief decided pay me a visit! and completley wiped me out urgghh. A few months ago i decided to buy another bike and start riding. i bought a 03 cr 250 which is very clean and although a good runner it was lil noisy so decided to bite the bullet and get the engine rebuilt, whilst i serviced all other bits like sus linkage bushes, tyres and a good general clean. Had the engine bak, built her all back up and took it on the flat back feild for a very steady bed in and then changed the oil. Everything felt perfect like a new un ha ha. The following weekend me and a friend took the bikes to a track and although his is the same year and bike and is still on the original piston (has not been ridden alot at all!) it just felt alot harder to ride and get along with. The bike was sriking in after first kick everytime and all was well! After getting back that day i was givin her a wash when i noticed sumthing that drained my blood, a hairline fracture running round the back of each cylinder bolt. the ones between cylinder and inlet port. Was suggested it would be ok to weld as it hadnt fractured completely to the seat. but after getting it built back up today with rite torque settings it split again without even starting it up, not immediatley either as i was finishing putting the fairings on i heard a crack and realised wat it was
any help would be grateful as i am banging my head on brick wall cheers
