inner rotor

Hi mate, I wouldnt use inner rotor, most new china bikes have them fitted & are pigs, there is not enough weight on crank shaft so engines like stallin in corners etc when backing off, also you can over rev the engine, my choice is outer rotor or stock ignition, My mate put tokyo mods outer rotor in a 140 motorvert & made a big difference & was a lot easier to ride & gained a couple of horsepower. 50 nut

IRK's don't give you more power, they just help the engine rev up quicker. an IRK on a trail bike bike is a downgrade you'll lose all your bottom end torque and stall allot when trying to go over obstacles.

If you want more power then look at some aftermarket cams, they'll make a huge difference.

Inner rotor is a bad idea for what you want. As said above, no power gain at all. Just revs its tits off.

Ive got an Outer rotor on my Daytona and its not bad. Revs fast, but not so fast that its hard to ride. Keep your stock setup man.

theres pitster pro on ebay(dhz under a different name) that sells a set, with springs(required) for $110 approx. watch out for the "anti kickback" setup if you dont have one fitted to your engine already...

theres akunar with 3 or 4 styles, different durations and lifts etc...for low end torque, hi end power etc...

t bolt usa...takegawa... same deal, various profiles for different applications. decompression cams for easy starting, la de da...




do a bit of searching, i couldnt be screwed myself

they dont work ^^^^^^ at all

most of the time the pulse generator is in the wrong spot and the fly wheel being to light picks up at the wrong spot which cause's kick back and the stalling at any chance possible

cam or 150cc motor will make it faster
