Carb tuning Evo after V&H install

craiger62 · #1 05-20-2008, 08:46 AM

I am installing V&H Shortshot staggered pipes on my 98 Fatboy, carb Evo. The engine and carb are stock.
I bought a carb re-jetting kit and high flow intake.
Can anyone tell me what the recommended jetting is for this set up?

Thanks,

Craig

Craig,you probley need a 200 main,and a 46 slow.Jets are fairley cheap,is your carb still stock meaning you can't adjust it?

I'm sorry but I have to say something here....buckmc do you realize your telling someone half way around the world what jet to use? Do you know what altitudes he lives at? Do you know what the temp runs there? do you know the humidity there?

I'm not calling you stupid or trying to insult you in any way, you might be the smartest man alive for all I know but I am telling you that your taking on a lot of responsibility telling some one what jet to use in a carb........if your wrong it could cause damage to that guys motor. Sorry guys I do have a problem when people at sea level tells someone in Denver what jets to use and this isn't just targeted at Buckmc....this is for all you that give this kind of information out......be careful and responsible for what you suggest to others.

Again Buckmc, I am not in anyway trying to cause an argument or discredit you or offend you at all....please don't think that I am.
I'm just concerned. I think a dyno run with the AFR reading would be the only way to answer that question safely.

Your a big man Buckmc....

I used to do the same thing until I started using the Dyno and drag racing across the country about 10 years ago, I couldn't believe how much the fuel delivery changed from town to town with different altitudes after dyno tuning the bike at 2500'. The difference in jetting between Reading Pa to Bristol Tenn was mind boggling.

Thanks for talking my post the way it was written....not many would do that, you have my respect.

A 200 main seems awfull big for a stage one 80" EVO.
