I came across an 1987 SRV 540. I messed around and got it running pretty good. I got one problem.....
It starts easy....Idles fine. When you punch it (WOT) it runs excellent for a couple seconds then falls to 5000 rpms or so and wont go any faster. If I stop for a couple seconds then hit it it does the exact same thing.
Is this a fuel issue? Is the float bowl running out of gas....pump not keeping up?
ANy body had experience with this I could use your help.
Thanks
P.S.
It has the stock keihin carb.
I have taken apart and cleaned the carb.
No airbox....looks like a K&N filter.
I disabled the oiling system.....I run premix.
