hello i've just bought a psn lightened flywheel off a runner 125 will i be able to use it on my sr 125 ? or will ineed the stator too, thanks
u need the runner stator 2 i think and ull need thread the holes 2 screw ur fan in but runner stator and magneto is better then the ac ones on a typh/sr so think f it as an upgrade
hello all i've put this flywheel on and scoot seems to run fine , but i've been told that if its a runner flywheel my timing will be out by 3 degrees ? does anyone know if this is correct , i thought the timing would be set by posistion of the stator ?
you need a different cdi also... match the stator flywheel and cdi.. alwas.. the timing difference is the main reason TO use a runner setup over the yphoon as the typh electrical system was strangled down from the runner type on the 150 ac engine's... even wiht a small bore cyliner (the ac 125) it makes too much power to be learner legal. hence they lazied it up, it also keeps the heat down at idle/in traffic as the ac cant shed heat at varied rpm's/speeds... this is the main advantage to the wc, the fact the engine is a more stabletemperature.. fuck all to do with how fast it go's... its more how flexible the USAGE of the engine is. ie, in real driving conditions a wc will be better (traffic, driving as you should) an ac engine is no less of a hooligans tool and will work just as well as a wc at full throttle. you can obviously port a wc engine further because of the above factors, but prittymuch nobody on the site would notice a poer loss going between wc/ac. so ye... need the cdi to match as this ajusts the timing (hence you have one) the stati timing is meaningless as its offset against the cdi's set rpm rate... the static timng could be 110 degree out if you physically time it, but the offset programmed into the cdi would still determin the ACTUAL timing... its digital ignition.. like injection,the crankshaft sensor can be anywhere on the crank, the ecu knows when this is and times the 4/6/8/12 sparks around this set static figure... completly different to analogue/manual/fixed ignition (like distributors in older cars or pickup's wiht built in coil's like minimoto's have) so anything you can messure manually/wihtout runniung the engine wiht a timing light on a cdi based system is irelevent.. get it on there, with the cdi/stator.... you would notice a difference wiht ether mod, so both together will be a verry noticable difference.
