I graduated from MMI so I have a small amount of knowledge/mechanical aptitude, with that said, here is what I'm experiencing.
First recieved this bike and got it to start but it ran really rough, hot and popping. I assumed a good carb clean and I'd be off with an awesome bike/steal. I pop the seat off and the aircleaner is destroyed. Replace it and clean the carby out real good, hook everything back up and start the 4 stroke shuffle. After kicking myself stupid, adjusting the pilot (leak on yamaha?... adj. screw anyways...) trying choke, no choke, hot start, adjust idle knob... nothing. If I do get it to light up its still the same pop pop fizz fizz oh shit its hot! lol
So I go to work do my research.... Never had a bike with a manual hotstart before so I replace the worn out tubing on it, test the button it holds all the pressure I can put to it... Put a freshy plug in it, gapped correctly.... kick kick kick same old song and dance. I got it to run ONCE and it sounded GOOOOD. only problem was I had the choke AND hotstart on hahaha, im assuming a freak accident as it died shortly after and returned to pop pop fizz fizz when I did get it going.
I decided to check the tps, as i havent had a carb bike with those either lol I test the resistance and I'm getting 6.11 k ohms fully closed at about 80 degrees F. spec is 4 k - 6 k at 20 degrees celcius, or 68 degrees F. could this be my problem? i'm really hoping not to have to throw 300 onto the bike right away as the wifey is already pissed I got a new "toy" hahaha I am going to try and kick it tomorrow (too late now) with the tps disconnected and see what happens. Can it run decent without a tps? any way to service/fix it? (i know manufacturer says no but I know you guys got some tricks up your sleeve, right? )
anywho... if no change with the tps disconnected I'll rip the valve cover off and see what my clearances are looking like. (i know i know i shoulda checked these first but I wanna ride... hahahaha)
Well, sorry its long as hell, but any help/insight would be greatly appreciated.
Thank you for your time,
P.S. Excellent site with what seems like a good bunch of people... rare find these days hahah
