2011 EC300 race jetting

[memphis2857]

I am gonna ask the question because I am lazy and to be quite honest I have a hard time wading through all the jetting topics. I need some baseline settings in the jetting department. I have the asII 38mm carb. I will be running Motul 800 at 50:1 (unless you say otherwise). Right now the bike is on stock jetting and the previous owner ran am soil interceptor in it. The plug shows that it is a just a tick rich and it spooges all over everything. The back fender is black. That being said the bike runs pretty good. The only thing I don't like is when it comes on the pipe it EXPLODES and the front wheel is in the air. I am thinking of dropping the main jet one size but I need suggestions on the needle and pilot

Have a look and see whats in there first. I'd guess stock needle based on how you've described it runs.

Memphis, pull the head and get the squish corrected. It will make your jetting life easier.

Ok so far it looks like a n1ef needle on the top clip. I have another needle that came with the bike new. It is marked CHN? Never heard of it before

Take that needle and stick it in the nearest voodoo doll! The second needle is the homologation part iirc - that and the 115 main you likely also got.

You're likely going to want to be in the NEDJ or NEDW range (but again, check the jetting threads because Jake didn't do all that work for nothing )

Pilot likely a 40 or 42 depending on temp, and mains in the 175-180 range if you're on the gas.

Oil is a sticky subject (haha) but anything will run cleaner once you get the jetting sorted. We run Amsoil Dominator (or the Motul 800) at 50:1 with non-ethanol 92 gas.

Agreed. This is a very good setup. With or without headwork.

Roger that.

If turns out to be too mild go for an N3xx needle with same diameter, and half a clip richer.. It'll still run similar off the bottom, but transition from mid to top much harder.

Thanks guys. Will report back later
