Possible fuel pump issues...testing
So you know, its an '04 600rr but its in a quad, not a bike anymore. Its been in there ~2 years and Ive had a few fuel issues, but this one is new.
At first the engine would hesitate nonstop at about 8000, came to find out I had the fuel line tied too tight to the frame.
Since then the engine has run flawlessly.
Now it still runs perfect until about 12-13000 rpm, then its done, it will not go past that unless I force it to (hold the throttle in first gear.)
The fuel line is fine, no restrictions. This doesnt sound like an ignition problem to me, it runs absolutely normal until that point, idles fine, good power.
Heres my question now, first your opinions on the problem.
Second, how can I test the fuel pressure. I have an autometer electric fuel pressure gauge left over from parting out my car and would love to hook it up permanently, but cant think of a way to tie it in.
