Cost of Machining Oil slinger for inner rotor kit.
G'day miniriders, I just brought an inner Rotor Kit, but now I need somebody to machine the oil slinger for me so that the motor does not kick back. Does anybody know what I should pay for such a job and how much time the job takes? Cheers, hope you got a ride in today.

it wont stop kick back (if any thing it will make it worse) but it must be done or you will destroy crank as you have just lightened one side considerably and the other has the weight that use to counterract the wieght you have just removed.One side will spin up super fast leaving the other behind resulting in a mighty BANG. If this mod is being run with a HC piston DO NOT KICK START ,ONLY BUMP START or you will be looking for a new engine case( to be on the safe side bump start it even if it does not HC piston, kick start it only in emergency
^^^ ONLY on this site have i heard this about IRK's
If you advance the timing to much thats when things go wrong.. Big discusions about IRK mods on planetmini's site and if you put a IRK on dont lighten the oil slinger, is said over and over again.. You can lighten the flywheel and he oil slinger but not have a lighen'd oil sling with IRK..

i run timming all the way retarded and i have a pile of stuffed crankes from mates bikes that have run just rotor, i'm a member of planetminis and this question is so hard to get a sure answer on. If you ring MOJO ,50s HQ, MOTO SCOOT who all run race bikes they will tell you what i have told people, and yes i have cracked cases but never destroyed a crank. That is with oil slinger and rotor but i put my cracked cases down to to much comp 13.0:1 and trying to squeeze to much advance on the timing
so is it easy to crack casings with an inner rotor kit?

so if you run an irk and lighten the oil slinger than you cant kick start your bike why is this is it cos it catches the kick start gear and tears it to pieces??
what type of compression does the high comp piston you sell roost have? in terms of a ratio

12.0: 1 and it my case it did not tear it to peices it caught it and cracked the case this happened more than once
with a piston that i bought off u and the irk and then machine down the oil slinger will i still have the same problom or will i need to bump start it all the time?

50's HQ are doing the work for you , just ask Mark he will explain it all to you, then if you dont beleive him ring mojo in Vic, then Terry at Moto Scoot Springwood and they will tell you the same thing, but is is adviceable to bumpstart it but i'm sure they will say you can kick start it just make sure timming is all the way to retard
