2000 426 Starts then quits

13 posts in this topic

When I try to start the 426 it fires up and idles for 2 seconds and then quickly dies. Start it again and the same problem over and over. Will not idle for more than 2 seconds. Choke on or off doesn't matter. Thinking maybe a carb problem. Any help would be great.

Probably that, and get rid of the gas itself. In fact you might try fresh fuel first. I've seen gas so stale it wouldn't ignite with a match.

recently fixed a kid's 08 yzf at the track - everyone was scratching their heads standing there (funny how many can ride but not wrench) - same issue - it was some crud that was in the bowl, 30 seconds and he was off like a banshee.

A season of riding will do that no matter how careful you are with filling your bike.

Yes, do you thing a lengthy carb clean might do the trick?

It surely wouldn't hurt. Keep away from automotive carb cleaner. If you use it keep it off of rubber parts as it makes them swell.

Here's what you need to use for best results:

That can be true of automotive carb dip type cleaners, but generally not of carb cleaner sprays. It's certainly not true of Berryman's B12.
