Tired of lack of power... time to repair the phantom problem.
well, the last two weekend I have gone on 'trips'. Last weekend I went 175 miles, yesterday 220 miles. Both times the bike lacks the power it had last spring when I bought it, and has a very hard time over 5k RPMs and/or 75+. Sometimes it will do 80 mph, but if there is the slightest hill she drops 10-15 mph and struggles. if I am cruising at 70 at approx 3/4 throttle, she's pretty good. However if I go to full throttle she struggles and slow right down.
I have degoated, and drilled baffles, have the K&N stock replacement air filters, and I cleaned the carbs last year.
I am thinking that if I have to pull the carbs, I will just do the ear shave and have it all out at once.
Stock jets are still in there, my 138 and 140 jets are somewhere here but got a little mixed up in the move. the bike has been running this way since the last part of last fall. It has it's spurts where it will go 90, but that's only down hill...
After seeing Dave's post and thread, I am gonna ask for the much needed help...if i have time before work tonight, I will check the plugs- they will be replaced this weekend as will be ordering some online (NGK Iridium)
I work until Friday so the weekend will be my fixing time and won't have but a few hours each day.
any help would be great!
PS- I am at a higher altitude (4400') than I was in MI, but it still runs near the same way.. I think it's lean?
