can anyone tell me the proper main jet jetting size for e series slip -on with a k&n filter and stock headpipes?can i get away just doing the main jets or do i have to do the pilots and needle also? I don't like to mess with the carb to much.

 

pick up a k&n jet kit directions work well and will tell you what jet for your elevation.

 

I have the E-series slip on with the K&N (and airbox mods) and run the 150/155 mikuni jets without the aftermarket needles. I have run this way for a year now.

I have just ordered an E-series header with the DynoJet kit. I hear that the jet kit with the improved needles provides alot better performance than the stock needls and jets. I am going to install the kit when I install the header.

 

Go with a Dyno-Jet kit. You can just go up larger on the mains but your cheeting yourself out of some performance. Do it right the first time, take the extra time and make all instructed changes. You wont be sorry!

 

How much is the dyno jet kit?

 

About $65.00-$70.00 well worth it comes with various jets for different altitudes,springs,and needles. Plus recomendations to get it jetted just right.[img]i/expressions/face-icon-small-wink.gif[/img]
