Hey just looking for some advice on tuning a runner sp 125...done a few visual mods now want some ideas on tuning wise...any help wud be good....cheers
172cc malossi barrel+ porting work, race crank 52/54/55mm, 25mm carb, pm pipe, gear kit, variator, to name but a few bits.
I fitted the following Pm 172 head TDR pipe 25mm carb sorted roller weights and springs carbon reeds its a real rocket and great fun! mines now stripped and im looking to lighten the flywheel and maybe do a few other bits. but the big power comes from the 172, even if you leave the bike stock and just alter the jetting you will still love the power i would like to know more about the gearing kits and using a 180 variator as i run standard gearing which the bike easily pulls off the clocks. i just dont want too loose that bottom end grunt
Okay cheers...currently its got a 172 kit on it and a exhaust...but im still using standard carb with different jet...what differece to performance wise will a 25 mm carb do...cheers
i never ran mine in stages i just jumped in and got it all done in one go! so i cant honestly say, mud imagine bottom and mid range will be improved i plan to have my fly wheel lightened and such, maybe change the variator and drop the electric start etc
Okay thanks mate...what u mean by drop the electric start??? Bit new to this.lol...any ideas on the best exhaust for performance...currently running a gianelli pipe...tried looking up on spec but cant find anything about them...any ideas???
i run a tdr which im happy with, but may switch to a pm 360 if i have the cash and do the bike up properly i think they are all similar you may bget better power low mid or high depending on pipe but over all youl be happy
