Hey guys, I'm new to the site, but from what I've seen here alot of you guys know your stuff whenever it comes to the Eigers. I've recently snorkeled my Eiger and added Penland Pro series exhaust. HMF recommended that the main jet (a 55) be replaced with a 135 jet for warranty. My altitude here is about 600-700 feet. Can anyone give me some tips on what size jets to use and which ones to replace at the given altitude? None of the other jets have been replaced or adjusted. Only the main jet.

 

Oh yeah, because obviously it isn't running right

 

The main jet should have been 122 from factory. Most people that have put in 130-135 has also put holes in there intake to get more airflow. I would say that 135 is high with a snokel on it. There are some good post on here about adjusting the carb and different sizes of jets. Just use the search.
