need a starting point on setting up 90

[ace75]

I bought a 90cc motor that has a freshly rebuilt and ported (hetrick) top end on it. It has a cast cylinder on it. It came with a brand new pwk 28 and a brand new gen 3 pipe. I have a 2010 50cc in the quad now. Can I run the entire ignition system from that 50 on the 90? and any ideas where to start with jetting?

the stock 50 ignition may be small small taper and the 90 crank may be large taper, requiring the purchase of some parts but If you have buy something you may consider a pvl instead of more stock parts. Are you going to be racing this quad?

yes, endurocross racing.

You will have to have a ignition for a 90cc so i would buy a pvl if the class permits it and i would also get and over range kit if it does not already have that.My son races races mx so i really don't know what spring/belt/roller combo will live an hour through the woods but i'm sure some one will chime in here to help you.

Thanks a lot for your replies, can someone educate me on the pvl. Is it a install and go? What comes with it? Can I just purchase the stock 90 large taper flywheel and use the 50 stator to get us by or is the 90 stator different from the 50?

Not an install and go.You will have to time your engine.It comes with the complete ignition set-up.
