A Lean Machine

Post by skippy »

Went for a ride the other day and slowed down for a corner, the bike started backfiring and then stalled. It started again but ran poorly lacking power and I had to keep up the revs to stop it stalling again.
When home I checked the plug and it was white. I removed the bowl and the filter in the bottom, cleaned it and checked the main and needle jets. There was plenty of fuel flowing from the tank.
I had difficulty starting it and it ran missing a lot and wouldn't idle. So i pulled the carb and cleaned the idle jet as well. When i checked the fuel flow into the bowl it was very slow, so I put a hole in the filter and fitted it all back again. I got it started again it was very rich on the idle, which I adjusted up. Now it run well again.
So was it the filter or the idle path which didn't seem to be blocked?

water in the fuel clinging to the gauze in the filter preventing normal flow....

No, but it is a super fine plastic filter. I had trouble with a similar type of filter on a small 2 stroke that clogged up with the oil in the fuel.

Does the fuel that you use have ethanal in it? It gave my british bikes fits until I went to 100 octane Av gas.

hi skypp,

I ask myself: dos it really need a ( external ) filter ??

as in my case, I have fitted on each tab a filter inside the fuel tank, so the external additional filter just before the carbi is probably more something for my brain ( head ) than for having clean fuel :oops: :oops:

IMO, it has more the sense of showing up some debris coming from the tank,- making them really visual.

Your right Beat, the filter is in the bottom of the amal carb and it is now disabled as i have tap filters as well. The filter is also the washer that seals the inlet.

hi slipp

as we both thinking the fuel is filtered good enough, I do still ask myself : is there a neat solution to put inline the fuel hose just to keep the big parts ore evan water drops and showing them if any are around?
maybe in other places of this globe there is something like in use already :?:
