EBAY FUEL TAP CONVERSION... ANY GOOD?

[Neosophist]

Believe it or not, i do, or at least i think thats what is happening! I regularly do a 100 mile round trip in the early hours mostly on dual carriageway. After about 5-10 minutes lying flat on the tank with the needle buried in the red the engine looses power and the revs drop. Rolling off slightly, the bike maintains about 12000rpm but wont rev any higher. But if i slow for a mile or two and then open it up shes straight back up to the redline!
The tap has been fully rebuilt and the vacuum hose replaced, so im left scratching my head once again! My bike has been on the rolling road and had the jetting tweaked (not sure what jets) if this makes any odds!

5 - 10 minutes at full speed will probably cause fuel starvation, especially if you have slightly larger jets.

Most people dont drive around 130mph for prolonged periods of time on public roads, which is why then don't get the issue.

I see! Looks like ill have to order another tap conversion off of flea bay then.

I bought one for my race bike and had it fitted within about half an hour.... no leaks, tap turns on and off, the reserve function still works and the flow has definitely increased! Happy Days!

Thanks to everyone for your input!
