hey guys i need a little help. i got a 91 and i got the bike in pieces and i finally got it together (so i think) and it wont start it has spark its got compression. i looked in and smelled the carbs and it dont smell like there is gas in there but i think i have it all right the bike is gravity feed right? Please help I want to ride so bad!!!!

 

Unless you have a petcock off an F3, the F2 has a vacuum operated petcock. There should be a hose running from cylinder #1 to the gas tank.

 

were on the petcock does the hose from #1 go exactly or does it go straight to the gas tank? The help is really appreciated

 

the petcock should have two outlet nipples. one large and one small. the large one is for the fuel line. the small one is for the vacuum line.

 

I have now figured out that my bike has compression it has spark and there is fuel in the carbs but it still isnt firing and it is turning over kinda slow so i hooked up my car battery to it which i just bought two days ago and its still slow could it be the starter and if it is can i put a f1 starter in it

 

are any of the carbs clogged?

 

I dont know what its called but i loosened these screws at the bottom of the carbs and gas came out idk if that helps to tell if it clogged but how would i check that?? but i think its the starter cuz i took the one out of my bike and i took one out of a hurricane and put power to them with a battery charger and the hurricane starter sounded strong and the one off my f2 starter sounded weak and weird

 

Before you start throwing parts at a problem, I would suggest removing the carbs and giving them a good cleaning.

If you want to further diagnose a starter/electrical issue, I'd suggest bump starting your bike.

 

so how do i clean the carbs just take them off and spray them out with carb spray??? And what do you mean bump start? Do you mean pop the clutch? Sorry if i ask to many questions im very green when it comes to these bikes just trying to learn, thanks for all the help

 

look for a video online(youtube). basically you take the bowls off(The bowls are the things held on by 4 screws with the screw you checked on them. lol..good explaining uk?) and in there you will find carbon build up. clean everything take the 3 jets out and spray them and blow them out.... uh.. yeah.. so like i said... look for a vid on youtube. i just took my... medicine and cant give a walkthrough for the life of me.
