Idle stalling
« on: November 17, 2010, 01:13:54 PM »
Howdy

I've a 89 400 and at idle the number four cyclinder dosen't seem to fire and is casuing the bike to stall. Currently I have the idle screw set so the engine revs at 2500rpm so it won't stall. It runs fine at speed. Anyone had anything simlar happen?

Cheers

Have you checked for vacuum leaks at hoses, diaphragm, & manifold?

It's more fun to ride a slow bike fast than a fast bike slow.
