Finally was able to get to the track

Was able to get to the track again recently. Worst i done did couldn't break over 90mph in the 8th mile or 1.75 60' lol. Pretty sure bike is starving for fuel bad. Which is weird cause its super rich at idle, if you rev it u get black smoke if u let it idle with stock fuel longer then a couple minutes it'd foul up new plugs. Bike would pull hard until about 8.5-9.5k then kind of fall on its face. Going to reverse everything my dad has did or undid to my bike cause it would pull to 11-12k before.
I did the fuel filter mod and he put a screw back in it thinking that was causing it to be super rich but it didn't help and it has his old fuel pump he put it on after the fuel filter mod i didn't get the clip right on the pressure regulator and it popped off and he switched the pump before he noticed it popped off. Anything else yall could think of that could i could try?

Good news though did get my 2nd gear fixed, should've got the 6th gear that has the teeth for 2nd to but going to send off to get undercut this winter. Also got my jerky throttle fixed would've never thought the gps could cause it but thanks to yall in another post i got that figured out. Also put new clutches in and got co2 airshifter installed with the boost by smith harness and shift light figured id be doing better since all i had to do was launch but the bike had other plans lol.

Lowered mine 5/8 inch in front and reset the lowering links but we're bottomed out. Ended up adjusting shock length to get arm where I wanted. Reset sag in shock and would have bet money I would have a better time. Was the worst time at the track I can remember ever having. Spin twice, bogged once and was crappy the other two. Keep trying, well get it figured out.

Guess u had to go back to the drawing board lol. Drag racing is a love hate relationship, its a fine line between what these bikes going to lovr and hate lol. I think my dad got it figured out though He put his throttle bodies, tank, computer and sensors that go on that little bracket on the side of the frame on it and. Bike would rev all the way through the gears on the bike stand. Just have to see if it'll do it with a load on it. Weird thing is on my ecu i had pulled fuel to help see if that gets it to stop idling so rich and it helped but with my dads ecu with bigger injectors and a tune that has like +5% fuel everywhere its not shooting black smoke like with mine. Going to put my stuff back on 1 by 1 and see when it comes back

Well got my problems sorted but 98% chance of rain tomorrow. New throttles bodies, injectors, and fuel pump bike runs excellent. Can idle at 1k now and bike pulls hard af in all gears

Do you know which of those were causing the problem

Ima say a mixture of the throttle bodies and injectors. I bought the previous set of injectors off ebay ad said they were stock but they mustve been big injectors cause it was super rich everywhere. Probably could've got by with a throttle body sync and stock flow injectors. Replaced fuel pump(bosch 69420) as well just to be on the safe side and make sure the whole fuel system was good.

hello everyone

It is loading and unloading a curve on the fork when it pops out of gear. This is transferred to the pin pushing on the drum. It essentially peens one area of the drum. It may leave a mark, which is undesirable.
