Welcome. Does the bike turn over with the starter ?

Quote:

Those sound like the carb vent hoses. They tuck into the rectangular frame backbone under the tank (nearest the seat).

PS:  An engine needs three things.  

Spark
Air
Fuel

(of course there are others, but the all revolve around those three things.)

You have spark,
You should be getting air, but maybe not enough or in the correct places(air jets in carb and such)
Same with the gas, petcock and carb, gotta clean and check em

Majstore,
99% sure, You have to clean the carburetor. If You have never done this, it will be a little chalenging to explain everything.
I'll try in couple of steps.
1. remove the gas tank.
2.Remove the battery box cover
3.loosen the clamps in front and behind the carb.
4. remove the gas cable from the carb.
5.remove the top of the carb/You might have some troubles with the 4 screws/
6.jently remove the slider with the diaphragm. Be careful, because it might be stuck pretty bad.
Now is the moment to do the " white spacer mod"
7.twist the carb 45 degrees. Now You have an access to the 4 float bowl screws.
8. remove the float bowl
9.take out all the removable jets and cleah them thoroughly with thin wire and carb. cleaner. LOOK AT THE PICTURES AND MAKE SURE YOU DON"T LOSE ANYTHING. The most important is the pilot jet. Take it out and make sure You see a light thru it when done.
10. Remove the float  . Clean it nice and make sure it moves freely on the float axle/pin/.
11. remove the float valve assy- the needle and the brass seat. Clean them perfectly /especially the inside of the brass piece/.
12. replace the rubber O-ring around the brass float valve /make sure the new one seals good /
13. go to the desired main jet.
   PUT EVERYTHING BACK THE WAY IT WAS BEFORE .

Thank you all for comments and welcomes! This place is perfect for me right now (my wife does not want to talk to be about these issues!).
Jesse - I would love to see if I have exhaust problems but so far did not ride this girl (or pregnant dog-we'll see). By the way, she is dark blue (well, bad people would say purple) and from outside looks great for '92.

It looks like I need to do the carb job! (hate the sound of it). As soon as I drained fuel from carb, it filled back and started but very, very rough. It would work only for 1-2 minutes and would die. Tried several times - same thing. To get more gas, turned from ON to PRI, but after 3-4 tries got fuel leaking badly from somewhere around the carb - could not see from where. ***What happened???***

Another thing drain plug at bottom of the carb cup is not very tight (but not leaking fuel at all) - was able to open with my fingers and when used tools to screw back would just turn around (still not leak from there).***Is it supposed to be like that???***

Slavy - by the way you put that 'e' I think you speak my language?

Sounds like the carb is clogged up. Here are a couple tips for working on carbs, first have a clean work bench so the little parts don't disappear under stuff. Work on a shop towel or clean rag to keep small parts from bouncing when they fall out of the carb. Take your time with the job, if you get stumped put it down and walk away for a few minutes. Don't force anything, if it doesn't fit then it doesn't belong there. Watch out for small parts when using spray carb cleaner, I've shot stuff across the shop with spray cleaner . Use the right tools and have fun, it will be worth it in the end.

You will not get the carb and jets clean by spraying it with carb cleaner in a can. The proper way is to diassemble the carb and put all the metal parts in a vat of real carb cleaner. I buy Gunk in a gallon can with a parts basket inside. This is the real stuff. It will get your carb looking like new. I rinse with water and blow dry with my air compressor.

Amen. That stuff will eat plastic, rubber, and your skin.
