Yea, well,, seems to me that kind of stuff otta be pretty much immediate, since, supposedly, the air fuel mixture is set once the slide reaches the top. That would make me doubt fuel delivery is up to the task., Have you pulled the petcock & looked at the screen filter?

But the picture in the Clymer manual shows a filter in the carburetor itself, apparently located just above the float needle seat. There is no mention that I can find in the text, either, so I have no idea how to get it out.

It comes out with the float valve seat.

Id pull the hose off the carb & put it in a jar & set the petcock to Prime & see how it flows. Then, Id do it again with the cap off the tank., Its not normal to wish for a dirty screen in the tank,.,but it would have been good news here..

Well Dang.......Why haven't I heard of this before? Shocked

This tiny little filter could cause a lot of problems if dirty.

Here is a link to the parts list.....the filter is # 20.

I doubt theres restrictions somewhere. THere were allso some particles coming out, I do not know where they came from. Maybe from the drainage treads, or if I am lucky, from the needle valve. I will check the bowl level to. I just need to find a plastic tube...

It's not a filter but a screen for larger debris items that may get to the carb if you do not have a proper fuel filter in your fuel line.
I've never had any junk show up in that little "filter" SCREEN when a proper fuel filter is used.

Hello again. I took aout the little filter. It was some particles there, but not enough to stop anything. I allso measured the bowl level and adjusted slightly for a bit higher level. But no big change.

I went for a test drive. THe bike runs so well on the lower circuits. It is a pleasure to drive it. Cruising 100kmh gives 12-12,5 o2. Very good. But when I twist the throttle it it climbs fast to 18,5. THe light is red and I do not like it. What can happend with the engine on this lean mix? I do not want to find out.

I fillrd the tank full allso. But no difference. I feel that the KN is the problem and I will try to modify the filter with a tube between the carb and the KN. Tongue

Maybe with a camera?

Anybody know what kinda MPG this thing gets ay 70? 40 MPG @ 60 MPH,,lets say.. so, it'll need to pass 1.5 gallons thru the carb in an hour. Thats 6 quarts in 60 minutes, or, a quart every 10 minutes,,& thats at 40 MPG,, @ 60 MPH,, Naaaah..
I cant imagine fuel flow being so restricted that it simply wont keep up, Unless, the cap is messed up.

Id pull the hose off the carb & put it into something large, but transparent or translucent & let a full tank start to drain. Let it go for a while, see if it slows.. then, pop the cap & see if it speeds up.

Check the cap, that's a good suggestion.

but I think the level is a bit high... er low... or ya gotta learn to ride right side up! Grin
