ok so i pulled the carbs off again and completely went through them and soaked them in cleaner, i got my backfire fixed one of the new plugs i just put in had fouled out already, but the problems im having now is that sometimes when i pull in the clutch it wants to rev out really high, and when its cold it will not start at all unless I spray gas in it, maybe need hotter plugs?

 

hmm......do you have the line that connects the two carbs for the choke hooked up? not the balance tube by the reeds but the one right off the carbs.

 

no I dont have that hooked up I dont know what it looks like or anything, also there is a small black hose that comes out of my crankcase right beside the water pump where does it go?

 

get a piece of rubber hose and hook that up prob will help with your problems....the other line your talking about i have no idea, its been awhile since i had mine, what does your repair manual say it is?

 

where do i put the hose at on the carbs? idk i dont have manual, btw thank you for being so helpful

 

do yourself a huge favor and get yourself a manual, its well worth the 30 or so bucks. look at the left side carb the one with the choke ****...you'll have the choke **** on one side of the carb but then on the other you will see a round port type thing sticking out. the hose runs from that port to the other port on the other carb. they are right across from each other.

 

thanks I will do that tomorrow, also im fouling out plugs pretty bad on my left side would that hose fix it on can i adjust something on my carb?

 

not sure about the carb settings, do a search on the net or ask in the yamaha forum about carb setting.

 

i have the identical problem with my bike , now its getting gas i can see it comming up from the needle my carb boot has a crack in it but it was not gone through , so would my reeds do that and the carb boot contribute to it
