Cbr 600 f3 won't run properly FIXED
I had the bike stored for 10 years, last time it was used on the track and had a minor crash ( could not make it in to the corner, exit the track on to the gravel, slow down and finally the bike fell, bike was running after the crash but didn't ride it anymore ), after 10 years fuel tank was nasty, as well as carbs, petcock, filter and pump, fuel tank has been cleaned, vent line it's almost fully clogged so I drilled 2 small holes next to the cap ( don't worry, I have a spare tank ) and now vents properly, petcock cleaned and check functionality ok, new filter and pump, carbs cleaned ( main and pilot jets as well as needles, choke valves, pilot screw, all new seals, etc ) new intake boots. After 10 years and all this work, it took 2 mins to start up, adjusted mixture and idle and was running ok, in neutral it can rev non stop all the way to the red line, but when in load if wide open it will bog from 6k to 7k rpm and around 11k rpm, if gentle with the gas it goes through smoothly and I can't find what's wrong with the bike. What I have done so far is, new spark plugs, replaced coil packs and replaced carbs, I'm about to get a cdi to check if that's the problem, I don't think is the rectifier as the battery is new and I've checked for proper battery charging values, if the cdi is not solving the issue what else could be, pulse generator? Wiring?
Thanks in advance for your comments and suggestions, any help would be gratefully received!
