i just got my 97 motor in my 95 cbr. so far the only problem i have is finding the hoses that go on the fittings on the carbs.i have the fittingscircled in the picture below,anyone know what goes there? can i just leave them unhooked or will that mess something up?? Thanks.

 

Ok i have the chilton book for f3 hondas ... ok all 3 circled are air vent tubes and yes they have to be hooked up. My advice is buy one of these books ... They are awsome, tells you every thingon howto over hall every inch of your bike ...The book iscalled "Haynes service and repair manual CBR F2,F3 Fours 91 to 98" and what you are looking for is on page 4.8 fuel and exhaust.... good luck with that and keep us posted

 

whatistheir purpose and why do they have to be hooked up??

 

clymer also makes a kick *** manual that will tell you how to take apart the engine and put it back together, among anything else you could want to know...generation specific

 

ive already got a manual, that is where i got this picture from. That is all that it shows. I would rather not hook them up if i can get away with it.

anybody know if i can just leave these unhooked??

 

They have to be hooked up, or your bike will run like crap. The center tube goes to the lower section of the vacuum piston in your carbs. The two small hoses on the sides go to a solenoid valve which control the route of airflow. One route goes out the front fairing and is activated at low speeds.The other ties into your air intake and is for higher speeds.

 

looks like i need to find a solenoid valve then. thanks

 

The solenoid valve is activated by the F3 gauges at 12mph. Do you have F3 gauges on your F2? If not, the solenoid valve will be worthless.

 

i dont have a F2, ive got a 95 f3 with a 97 F3 motor....

since the solenoid valve is activated at 12 mph, could i just hook both hoses into eachother and then bypass the solenoid valve and route the hoses how the are supposed to be at 12+ mph, im guessing they would be routed to the intake?? so it would be like the solenoid is constantly activated.... what do you think??

and i dont even know where to start with the big center hose, where is the hook up for the vaccum pistons on the carbs?

 

I found this hose diagram online somewhere, are the 3 things that are in-line besides the air solenoid valve just air filters? (see pic if you dont know what im talking about)
