Title: Which main and air jets for a 2165 CC with IDA'S Post by: Frenchy Dehoux on April 22, 2011, 04:14:57 am Well I finished building my fourth motor in 2 months . First one a 1835 CC with 42 DCNF 9 Webber the second motor a 2332 CC with IDA'S . Next one 2276 CC .Now I need a break before going to the Bug - In in a week. But my last motor is a 2165 CC with 48 IDA'S I have a turbo cam 1.4 rockers with straight cut gears 42 x 37 valves with an 0.10 for now but it will have a Joe Hunt magneto before too long and a Berg fat pulley. Any one with this combo give me an idea what you have for main jets air jets venturi etc it has 8.5 compression. Thanks Frenchy Title: Re: Which main and air jets for a 2165 CC with IDA'S Post by: deano on April 22, 2011, 05:00:11 am Frenchy, what size venturis are you planning to run on that 2165?

Looked away to do a few little calculations and there were already two responses ;D
I second the 155 main and 180 air to start with. |
