hey whats up to every 1 in cbr forum need some help with my bike. do i need an air vent solenoid and the heater hoses that go on the carb for my bike to run feels like it runs outa gas and when i let it idle for a minute itll run good for like a block then start feeling like its low on gas can it be that i have to big of a fuel filter the pump also ticks every few seconds

 

Not really sure about your problem, but I can tell you that you do not need the carb heater hoses. You do need the air vent solenoid though! It won't run right without it.

 

Make sure that you have connected the hoses correctly, you will get the sensation that the bike is running low on gas if they are connected incorrectly.

 

Sorry for the thread jacking. I know i do not have these on my bike. Runs fine through 3rd then just sucks ***. Are these hoses supposed to go in between the cars? (two hoses?) if yes where do they go to. I know i dont have the actually solenoid itself but i have some spare hose laying around to direct it.

 

Check your fuel lines too, they make just have residue built up inside, mine did and i got the occasional sputter from it too.

 

Boblasek,

Not sure what hoses your're referring to. The air vent solenoid system and the carburetor heat tubes are two separate things. The carb heat system just takes coolant from your water pump and sends it up through water jackets in all of the carb bodies. The carbs have 4 nipples on them where the hoses attach. The carb heat system is the one you don't need. Simply runrubber hose from your water pump to the top right of the cylinder head (there's a nipple there) and you have bypassed the system. You can also unbolt the thermo valve that mounts to the top of your crankcase.


Now the air vent system is a little more complicated. You should have a routing diagram sticker ontop of your airbox lid that details where everything goes. You basically have two hoses connecting to the front of the airbox area where the two tubes from the ram air connect. There's another hose coming from the float bowl balance tubes (these are the two little circular inlets that are on the front of your fairing). All these hoses go through the air vent solenoid. It's best to go on ronayers.com or some other microfiche to see how it all goes together.
