Hey guys, I've been reading here quite a bit and finally snagged a good deal on an 04 te450. The bike was originally well taken care of, the second owner bought it when the auto decompressor failed and then let it sit.
When I picked it up, it hardly ran, the seller could barely get it to idle for me. I took it home anyways and ironically, it started first try for me. I rode it down the block only to realize it was out of gas. Pushed it to the gas station, filled up, and off I went. Electric and kick start working fine as long as I used the manual decompressor. When I got home, I let it idle a little bit, then I shut it off. I tried to start it again, but it wouldn't go. Only little coughs from both kicking and electric start.
Over the past two days, I have ripped the carb apart 3 times, checked the valve clearances, charged the battery, checked tps, and spark. I got it to go once yesterday with a bit of starter fluid, and it ran great. Could not start it again after that, even with starter fluid.
Tl;DR:
Bike starts intermittently with no rhyme or reason. When I turn the electric starter over, the bike chugs and tries to fire, but doesnt get running, sometimes backfiring. If i run it wide open for a bit and then close the throttle and let the decompressor out, it seems to fire better, but rarely starts. Once it starts, the thing runs really well except for a bog/stall when I wack the throttle open from idle.
What I have done:
Cleaned carb and all jets, set float height to ~11mm/parallel with gasket surface
Checked choke valve, and accelerator pump
Plug has fuel residue on it
Fresh 91 octane gas
Checked for blue/white spark with multiple plugs
Put a fresh plug in anyways
Checked valve lash (loose on the intakes, perfect on the exhaust)
Checked tps (4.5k ohm closed, 990 ohm open)
I have a new decompressor lobe and needle valve seat on order since both are having issues
Things I plan to check/try:
Gear position sensor resistance
Cam Timing
Kill Switch, wiring
Crank on the fuel screw one way and then another.
Any Ideas? Maybe a failing crank trigger/stator? The bike lights up every time I turn it over, and the sparks seemed consistent when I was turning it over with the electric starter. The bike also seems to idle really rich in my opinion. Once I get it rev'd a little it runs better, the exhaust also stinks pretty bad during idle compared to my cbr600 and my room mate's wr450.
