OK the R is all of a sudden running like poo. It starts and idles fine, but when I get into the throttle at it surges, sputters and pops. Put in a new plug, and double checked the air fuel screw. Filter is clean. I am at a loss, it ran fine the last time I had it out and now not so much. Has HRC cam, Yosh full TRS, and custom tune buy local shop. Any input is appreciated.
When was the last time you had it out?
