stepped woddruff key/advanced ignition timing

GADGET · Guru

Yep put these on little pocket bikes made a big difference

NORFE · DTR Trusted Engine Builder

yeah its been a common mod over the years on all makes and models

you have to get it almost perfect tho or its melted piston time lol cry

mr karnage · Guru

yh i read overdoing it melts your piston lol

any idea where you could get it done

GADGET · Guru

You just buy it and fit it under the flywheel

NORFE · DTR Trusted Engine Builder

i dont think they make them off the shelf, it would have to be designed and machined then hardened

mr karnage · Guru

yh you would have to get one made up

i have no idea where though

GADGET · Guru

You can make one outta your original one if u only wanna go a couple degrees
