2011 EC 300E RB mod

[Gasaholic]

Does anyone have any experience with the RB mod to the carb?? I just a purchased a left-over 20011 300 with the RB mod done , would like it to pull strong off idle and be smooth thru mid . run alot of nasty single track so I want tractor type of power. Thanks in advance for any feed back.

You need to provide more information if you're looking for an accurate answer. Its like me saying "Hey I've got these FOX pants, anyone else got them? I like my pants to have some extra room around the knees for braces, but to fit right at the hips".

Basically.. What is the bike running like at the moment? Where is it running bad? too much hit? Whats your location, elevation, temp, and RH? What is the current jetting in the bike? Did RB head mod it, or just carb?

Two things. I had to up my pilot jet to get the bottom end I was looking for after RB got done with it, and two the 2010/11 had the powervalve misadjusted fairly often from the factory. There are many threads on here about it. Those two things helped mine a ton! I rode mine through a bunch of single track before really looking into it.

I hear most really like a 50T rear sprocket. I haven't put one on myself...but I will. That should make it the bike you expected, and much better than you will find elsewhere.
