Hello all im new to this forum and my 01 blater is my first bike ive been reading up on here but cant seem to figure out the problem i have a after market bills fatty and silencer 230 main running 40:1 high test i pulled carb out and tore down and cleaned checked reeds and there good clean air filter the bike is completely stock except pipe air screw set at 1-1/2 turns out plug is b8es will start on first kick runs great power in every gear tors deleted also.... my issues are in 6th gear at WOT after a 1/8th mile it will bogg is this normal a rev limiter? It will not do this if im just under WOT. And also sometimes at idle it revs up and down on its own in neutral.. on a hill in gear it will slowly slip stop slip stop almost as if a bad clutch but it shifts fine and finally i did a plug chop after i cleaned the carb and it was black... im thinking of drilling air box to see if helps im going do a compression test tonight as well. If anyone has some pointers please help me out ive learned so much already i just want sum experienced advise on what i can do otherwise bike runs great imo i just want it to run its best thanks
