GSF 600 K1 - Low end power problem

Hi Everyone,

A few months back I had an engine service (cam timing etc...) and since then the bike would "splutter" around 5000-7000 rpm. It also didn't start without giving it some throttle.

Since then I've had my restrictor taken off (2 years has flown by) and my carbs serviced (they were pretty clean apparently) with new inlet rubbers. This morning it was great but this afternoon it had real trouble starting and has very little power until 4000rpm. At one stage in stationary traffic it just died and took ages to start up again. 

It had run down to empty (reserve as well) but just got to the garage in time to fill it back up this morning and was fine onwards from there but this afternoon is when the problem started. Could sediment in the tank clog up my carbs? :doubt:

Thanks for looking :smile

hi bud , was the bike ok before the service? i cant see why the garage would 'adjust' cam timing .i would take it back to where you got it done and get them to recheck inlet for leaks ,also you may have got some crap in the carbs if its run low , more info if you can.

power loss

As albert88 says more info on this (cam timing/chain renewal/valve clearances/which/what) engine service.

From what you say it`s fuel starvation,

have you tried riding/running the bike with the fuel tap in "PRI" position to bypass the fuel tap diaphragm?

Have you any fuel in the fuel tap suction pipe leading to the nearest carb intake manifold?
