Backstory;
Bought a CHEAP keeway superlight, 2019 EFI model with 3500 miles on the clock. Non-runner because the ECU wasn't communicating with the fuel system - ignition side was fine.
Retrofitted a pre-EFI carb, intake and fuel tank and did 10k miles since July/August last year (600 mile round trips almost every other weekend), but it had a crack in the intake and ran lean, so I adjusted the carb to suit and never had an issue. I ordered a new carb and intake recently, and finally got round to fitting it, only to find it was completely the wrong intake. So I ordered another. And this one came with no vacuum port for the fuel tap. I fitted it anyway and butchered the tap to flow without vacuum. Went for a test ride, and the float bowl drained in about 4 miles of WOT on the dual carriageway. Gave it a minute or so and she fired right back up. I figured my butchering of the fuel tap was probably limiting flow, so got myself another non-vacuum tap (got a reserve now aswell), and fitted that this morning. I also set up the carb again with a colortune at various rev ranges and the bike runs absolutely fine, so I went for another test ride and got about 7 miles before the float bowl drained.
The carb is at a slightly different angle with the new intake, but is there something I could be missing as to why it's draining quicker than it's filling?
Cheers!
