There is something to be said about the factory design of giving weak voltage to the pump at idle and higher voltage to it at higher rpms. It...
That might be an Australian only part and hard to aquire elsewhere. It occurs to me I might be over thinking the situation. It should be very...
Hey, that sounds pretty good. The question then becomes price. Are these Carmtrols affordable?
There's also a test that can be done to measure fuel flow from the pump. You just bypass the safety relay with a jumper wire and measure the...
That's a good idea, but fuel bottles are quite expensive. I think they were $60-$70 which is why I never bought one. Have you seen any cheaper ones?
I sure do! Just read my posts in this thread: http://vfrworld.com/forums/showthread.php/29665-87-VFR-700-Fuel-Pump-not-pumping The relay...
If you suspect the fuel pump, just crank it and let it idle till it dies 10 seconds later and then check the float bowls. Attach a hose to the...
It does sound a little slow to return to idle. It may just be that you have your pilot screws turned out a little too far. If you get those a...
Nope, it's pretty much impossible to change it with the carbs together. You might have to separate them. Just be super careful not to crack the...
I'm not sure, but you might have mixed up thd float needle with the jet needle. They sound very similar. The float needle and seat are composed of...
Here is a link to a thread I wrote just now. It's got pics of the wire, fuse and rectifier. Hopefully it's good enough as my old photos are not...
I need to get home and look for the pics. I'll post them shortly.
I bought an FH011AA tall fin model from the 04-06 Yamaha R1. It's hidden under the left side tail piece. I took a lot of photos of the install,...
About carb tuning, it should have smooth power from idle to mid rpm, then around 5 or 6 thousand you should feel the power ramp up more steeply...
I polished by needle and seat bodies to make sure they moved up and down smoothly. The inside bore of the brass seat sometimes gets gritty so I...
I found a schematic for the F model, not FF, but it should be the same. The 5th wire in the connector is for the oil pressure switch, so it's...
I've forgotten everything in this thread, so I'll try and start from the beginning. Usually if one of your pulse generators becomes open after...
To clarify on what I was saying earlier: The 86 VFR700/750 gets its fuel relay signal from the yellow/green tachometer output wire from the...
The VF1000 is a different engine than the vfr700/750 we are talking about in this thread, but are similar in theory. The pulse generator coils by...
Now's the time to try and clean the fuel enrichment/choke circuit. You can't really take it apart without removing the linkage so you just have to...
Separate names with a comma.
