I was reading the threads on Eiger jetting. I am just wondering about jet sizes. I got a jet kit and it is saying to run the 118 main that came with the kit.(dynojet). Now if it is running lean everyone is going up to 130 135 range. Can anyone clarify this for me. Does dynojet mark their jets differently from stock jets?

 

Yes, the dynojet jets are marked differently than the carb manufacturers. I'm not familiar w/ the dynojet #'s, but I would just start w/ what they recommend and read the plug and go from there.

 

I went with the recommended 118 for my application but will try the 120 as the plug is very light tan.

 

What kind of horsepower can you get out of jetting an Eiger and maybe installing a K&N air filter? How much can it add to the top speed? What's the top speed after the mods?
