Was cleaning my carbs (yet agaaainnnn ) and i replaced all my fuel lines and saw some electrical tape on the wires going to the fuel pump. so i took the black cap off the bottom, and found this:



so i soldered and fixed that. i was mad at first... but them i remembered that the previous owner(s) did this:



who knows what some people got goin on in their minds. ANYWAYS. yeah i was cleaning the carbs cause i got BAD GASOLINE from the CITGO gas station by my house. didnt know it. i worked out of town for a while and the bike sat there and it jelled up in the float bowls. nasty nasty stuff. i cleaned them out all good and put everything back together and put the gas tank up on a shelf and put a very small amount of fuel in there and ran a fuel line to the fuel pump and got the bike warmed up then when it was choking out of fuel i dumped sea foam into the tank, let it suck that through and let it sit like the can said. then came back and poured a gallon of gas in the tank and revved the **** out of her and cleaned her out. havent ever had a better throttle response than now.

side note: i got vapor lock on the gas tank while i was letting it run after it was warmed up. i never got vapor lock on the tank while it was bolted to the bike. any ideas? it was choking out and i was like ok must be empty so i took the lid off and it was a force holding it down and i took it off and it hissed in, and the bike started running like normal.

 

Oh man, I wouldn't have bought that bike knowing the wiring ****... who the hell knows what else they did...

 

You don't have your vents capped do you? Might be a little too obvious but blocking those is the only way your tank will build vacuum like that.

 

I feel your pain. After my wreck I started going through all my wiring and re-looming it to make it all pretty and clean- I found 4 places where the PO had cut some wires, twisted them together, put some super glue over them and wrapped them in so cheap-o electrical tape. Being that electrical work is my career I about cried...LOL

 

Being a man I would have cried... all my wiring has been soldered and heat shrunk... I don't take chances when it comes to electrical...

 

are those those nipples that are side by side in a "Y" configuration in front of the drain nipples? if so, i think they might be clogged up with those mud wasps nests. dirt dobbers or something. the bottom side of my gas tank was muddy when i got it, the PO kept it outside in a barn.

should i stick something small up in there to try and clean them out? please, if you tell me i have to take my carbs off again to clean them... im going to go run out in traffic right now.

 

you should be able to get those tubes off without removing carbs...

 

When I got my F2 streetbike,the p/o had an HRC jet kit in it,a UNI air filter and a stock pipe.

Ugh.
