Hey guys. I just got a 38mm pwk for my 250r to go along with my PT highrev pipe. Over stock its a vast improvment but I dont think I have the thing just right. The bike runs great from idle to about 3/4 throttle but then it just feels really flat after that.
I was assuming with this pipe and carb most of my power would be past 1/2 throttle but that doesn't seem to be the case. I'll be the first to admit carb adjustment is not my strong point. The carb came with 170 main and I just stuck with the needle were it came stock middle clip postion. The air screw was at about 2 turns out. I honestly only play with it till the bike seems to run clean so I may just not have it adjusted correctly.
Other than the carb and pipe my bikes still pretty stock.
Any suggestions. My father seems to think I need to go to the next main jet but I'm not sure. I did a few plug chops and it seems fairly ok. I'm looking at a light paper bag brown in third at about 3/4 throttle. I know I should have but i never did any at WOT and don't think I' gonna get a chance to untill tomarrow. I tihnk I'm gonna try and find the next two jet sizes today so i at least have them to play with tomarrow.
