Idle increasing automatically LT F500F 2000 QRunner

Recommended Posts

Bought her sat not running, cleaned up card, bypassed Petcock, new battery, and after fiddling with manual idle screw got it to start normally.

Well, yesterday I rode her for a few mins, no issues and left it idling in neutral while I ran in my house and heard the rpm increasing so I ran outside and hopped on and drove it back to my barn.

What can cause the idle to automatically increase? I am kind of at a loss...I've googled and can only find pages about how to adjust the idle.

Not that I noticed...it was increasing idle while in neutral and rpm's kept increasing.  I am thinking its something in the carb although i cleaned it thoroughly...

      Hey just picked up another scrambler 850 was told the tps was bad.  This atv has been beet to hell.  Wiring has been tinkered with the crankcase has been replaced recently and the motor rebuilt (can see horizontal scores thru spark plug hole where it’s just been honed out and rebuilt)
      my guess is it was ragged out till the motor blew a rod and rebuilt but the clown that did it couldn’t get it to run again and sold it.  When I bought it it would pulse and smoke black at idle and die with throttle.
      New tps installed and it won’t run period.  I went to celebrate it and I’m getting 5 volts on 2 of the 3 wires running to the tps.  Is this normal and if so how should I celebrate it?

      Ok so just picked up an 02 ds 650 and the guy said he couldn't get it to start. He had a shop put new shims in it and I had them checked and they were ok now things I've done is new plugs even though guy had just put new plugs in it.. got new carb 42mm just like the one that was on it.. bought new intake manifold because the one that was on it someone got way to tweaked out and ported the shit out of it excuse my language but yeah so installed new intake manifold and it just won't start like its not getting enough fuel.  Timing seems to be right it does fire every now and again but just barely.. did a compression test today and it was at 90psi.. i know thats low but don't know where I'm losing compression.. valves we at .06 and .07 when checked im lost ive tried everything I know and can't figure it out
