1sick6 Posted November 7, 2013 Report Share Posted November 7, 2013 Hey every 1 I have just finished building a little stock stroke/ cylinder shee but I don't want to run the stock carbys and I have everything new to put some Keihin PJ 34mm carbys on it, but I would like to know ruff pilot and mains jetting to get me started. The engine isn't to much just Bills pipes, v force 2s, 22cc cool head, vortex ignition, and ported, I'm not sure what kind of porting it is but looks good. The new carbys came with 160 mains and 48pilots fitted and came with spare 168 - 45 jets. Any info would be great, thank you, Paul Quote Link to comment Share on other sites More sharing options...

Surfrjag Posted November 7, 2013 Report Share Posted November 7, 2013 Might start with 55pilot 160main and cel needle. Should be alittle rich and work your way down till its right. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted November 8, 2013 Report Share Posted November 8, 2013 ^ safe start. I'd imagine you will be around the 50/52 range pilot and 145-150 area. Depends on what the porting is but your pipes are pretty tame. Side note: the idle is set with the choke knobs. Quote Link to comment Share on other sites More sharing options...
Pasi S. Posted November 9, 2013 Report Share Posted November 9, 2013 My friend has unported stock cylinders, K&N filters, VF3´s, +4 timing, 20cc domes in PD head, T5 pipes and 34PJ´s. His jetting is 158-162 mains, 48 pilots. I can´t remember his needles, but they are KTM factory needles out of 36PWK´s. It runs good. CEL or CEK didn´t work with him. The KTM needle is richer down low comparing to CE* needles. What I´m trying to say is, your 34´s will do fine, you just need to jet them good. Start rich in mains and take your time.
