Lumpy bouncing idle

[paz]

From time to time, from start up, my R's idle is slightly lumpy and seems to 'bounce' slightly, the difference in the revs must only be about 10rpm, but it seems to move between like 900 and 910rpm.... it sorts itself out after a while.

Any ideas on the problem or is it just my R's idling personality coming though?

check pluggs, and clean AFM sensor!!!
maybe spray some carb cleaner in the inlet mainfold while engine is warm and idle it @ 2500 rpm.

if it has more aggressivly profiled cams it will idle lumpily

Cheers Stevo, shall try it.

Kyepan - AFAIK its running standard cams, mate of mine had it for 3 years before me and he thinks its got standard internals.

Just check your blanking plugs are still there, between throttle bodies and head. they do blow off sometimes. 8)
