another jetting ques.

[01/416ex]

Curtis sparks websits says run a 155min and a 45 pilot with the X6 system . Thats just an exhaust sys. alone I have a mid-range Webcam timing adv. key and magnum rev box which also has some timing advance.

I think I should go up a bit on the main what do you think?

Well thanks for nothing,

I put and outerwears cover on my airbox 170 main and a 42 pilot.

It has gobs of power now.

Sometimes you need a little patience;) , maybe they mean a 155 dyno jet main. Are you using a keihin jet? I would do a plug check though to make sure that its not running really rich. Oh, i would take the advanced key out if your runing a rev box with a timing advancement on it also. It may be overly advanced and running much hotter and you have more of a chance of detonation/preignition. Just my 2 cents.

Relax,

I ment I figured it out before I goy any responces.

I didn't use the Sparks key which is 6 deg. I have a 4 deg. key.

I do have to keep that in mind though.

I'm using Keihin jets Dyno jet calls for a 146 main. I have a buddy with a shop and I just opened a jet kit up and got the info off the card. But sometimes you need to hear what guys are really using not whats on paper.

Ran it tonight and plug chopped it and all is well with a 170/42 combo needle in stock position also.

Does anyone know how many degrees the Magnum box advances?

I know, I know, I'll wait for an answer. ;)
