blaster668 Posted January 30, 2007 Report Posted January 30, 2007 (edited) I'd like some rough ideas on where to start with jetting. 65 x 54 cub, 34 PJ carbs, FMF fatties, 17cc domes. Edited January 30, 2007 by blaster668 Quote

bigboybanshee Posted January 30, 2007 Report Posted January 30, 2007 And what type of port job, if any... Quote
blaster668 Posted January 30, 2007 Author Report Posted January 30, 2007 1000ft elevation, Riding temps vary between about 50-100 degrees F. It'll be on the colder side of that when I get this thing running. Ports are just gonna be cleaned up a little. Quote

dajogejr Posted February 2, 2007 Report Posted February 2, 2007 Dunno if this helps, but I ran a 48 pilot in my 35PWK carbs, but it was a 421 cub, not a stock bore/stroke like yours. Quote

Try the needle(s) wes suggested, then try different clips... Quote
