Title: Jetting recommendations Post by: Rocket Ron on May 11, 2013, 18:08:06 pm Looking for recommendations for jetting for my engine I know it's difficult but looking for a base to begin with
2276cc Fk46 cam Cb wedge port heads 10.8.1 compression ratio Ida's with 44 vents Full weight bug Short box Thanks in advance Title: Re: Jetting recommendations Post by: leec on May 11, 2013, 19:51:03 pm Check my thread that Richie replied to. Martin and I went out with that set up on the street and it drove lovely but had loads of top end compared to the 40 vent set up I had before.
This all in the 67? Lee Ps, will show you where to get a very good price on jets.... Title: Re: Jetting recommendations Post by: Rocket Ron on May 11, 2013, 23:17:01 pm Lee

Valve clearances at zero when cold ? Regards Ron Title: Re: Jetting recommendations Post by: richie on May 13, 2013, 10:27:30 am yep,valves at zero,excellent that it is nearly there now 8)
