OK so this is my first CBR.
I do not know where any of the vacuum or fuel lines go. I got the bike with all the lines disconnected and the tank off.
Ive already looked through the parts fiche and I get an idea about everything but still it doesnt show me where anything actually connects. I also read a ton of threads here, whatever has been answered in detail was either for a bike older or newer than mine and had entirely different lines.
I see where the PVC line from the valve cover goes to the airbox and the wide line in the middle of the carbs goes to the airbox. Those lines I figured out.
There is two sets of medium width lines, almost identical- on the top and the bottom of the carbs. They both go to the center of two carbs (1&2, 3&4 assuming) and to go Tee fittings-
The bottom one (toward the rear of the bike) has a shorter hose off the T fitting, and looks presumably like the fuel line.
The top one (toward the front of the bike) has a longer hose off the Tee fitting, and also looks like it could be a fuel line.
Now I dont know what carbs are numbered what, so im going to assume that if you are sitting on the bike (facing forward
), from left to right it goes #1, #2, #3, #4. Please correct me if im wrong.
Assuming these numbers correspond to the carbs, theres a nipple on the #2 sticking straight out that comes off the head, right below the carb- it has a line on it thats about 6 inches long- I am assuming that is the petcock vacuum line, correct me if im wrong please.
On the #4 (all the way to the right), there is a nipple coming right off the carb, pointing almost downward. When I try to start the bike I get a noticeable vacuum from this line. I have no idea where it is supposed to connect.
So four lines I dont know how to connect and maybe more that I havent even discovered!
There is also an F shaped vacuum line Tee fitting that has hoses connected to it. I assume that has something to do with the missing hoses. I have no idea where any of those lines go.
I am really appreciative of the newb help
