I recently had to put a motiopn pro twist throttle on my raptor 660 cause the stock one broke, and it was doing alright for the first few times i rode it (im in pennsylvania for college so only get to ride like once a month) but the last time i took it out i'd rev it up, and it would take like four or five seconds to rev back down, very unusual compared to what it used to do, when i let off the throttle goes back to idle like normal, its not like its sticking open and i dont know whats up with that.
i almost wrecked the first time it happent scared the $hit out of me!!!!
If anybody knows whats up id appreciate it if you could help.....if not oh well

 

I have still not recovered from a shoulder injury I suffered on New Years, when the throtle stuck on a dirt bike I was riding!

 

i have already been in one pretty severe dirtbike accident, and am not looking for another....Labor day weekend a couple years ago i wrecked a 1986 honda fat cat (old dirtbike with quad type tires) into a 1998 yamaha kodiak 400 4x4 and i ended up almost losing my leg, but luckily i only had to get like 30 staples across my knee and lost a toe. i was in the hospital for a couple of weeks and in a wheelchair for a few months!!

 

When the throtle stuck open, I was headed for a wall. From a wheelie, I had to lay it down or hit the wall. Found the brake at the last second, but in all the panic I couldn't manage to pull the clutch.
