Installed the cylinder.  Piston is real close to deck height at TDC.  Piston is even with the exhaust and transfers at bdc.

i got mine from LED you have to call him but i do not know if he sells them any more last i heard was i got the last one from him for awhile. i think he switched to only cpi cylinders. i was going to go 300 or 310 but those weren't available and he only had the 350.

Got er’ broke in.   Didn’t really have time to work on the jetting.  Had a 190 main in it and it was definitely too fat.  I was riding my 450R most of the time.

I don’t have time to ride much so it’ll be awhile.  Greg Huntley on Facebook has a lot of seat time on both ESR and led CEOs.  I’ve been messaging him a lot.  I could probably get you in touch with him if you want.  R u on Facebook?

No worries I’ll be lurking around here when you get a ride report. I can barely keep up with the Facebook pages. Too much clutter from the kids lol. At least if the R pages are anything like the diesel or performance boat pages I’m on.

It was running like shit, wondering now if it was just fat jetting or maybe I have another issue as well.  Ignition?  On the face of a dune, it wouldn’t pull.  No power.  Under load, fat jetting should run a little better.  Thinking out loud here. What do you guys think.  I’m running original stock ignition.  I’ve got a cr ignition but I didn’t want to change too much at one time.
