I have a TRX420TM7 that starts up fine but engine speed is about 2000 rpm's and wont go any lower. There is no mechamical blockage of the throttle cable, any suggestions would be appreciated....

You should take it to a mechanic or something. I really don't know on those EFI models. Or ask around other atv sites.

Don't really know why it fixed it, but I tried every trick I knew, disconnecting the battery to reset the computer, unplugging all the connections on the throttle body and a few more. As a last ditch effort I turned the key off and back on several times with the engine running, then turning it on before the engine could die. Did the same thing with the kill switch and on the first time back on, the engine dropped down to normal idle and has run perfectly since. Don't know why, but it worked. Must have reset something?????????????

I have a 420 that my friend rolled on me, now the fuel pump won't come on. Is there a collision switch or breaker
