the evo's running a bit odd
just a little background on my bike, its got 38000 total miles, and about 20k on a hop up kit. which included cam, 42mm mikuni carb, bored out, port and polish etc. whats happening is when i jump on the throttle, about 2/3rds of the way through my rpm range its dies out and lets out one big backfire. it only does it through first and second and gear, and when i get a good roll on the throttle it still happens, just not as drastically. any ideas? the 20k have been completely reliable and trouble free.
