Right.. Recently picked up a pm59 secondhand for 50 quid.lol.couldnt turn a offer that good down! :-D Bolted it on yesterday.... But feels no faster than std. Can tel needs slightly stiffer clutch springs but other than that all seems setup fine, ( rolers,jeting etc) Pm describe this pipe as a bolt on no further changes needed.but as i say doesnt realy seem to bring a power gain,:-( Any help apreciated, or am i jst expectin 2 much from a pipe alone! :-S
Cheers mate! thought summat along these lines,! and na its alrite m8 ive got a 172 kit coming in the next few weekss so it will come in usefull then!
there still worth a healthy top gain and higher powerband so the same power (ifr slightly more) is deliverd totally differently. there really not made for 125 timings tho tbh. try going up on roller weight as the 125's make power low and it may be sitting above the powerband. more revs dont always make more power
