If the tap is leaking, it will have to be replaced.
The seal kit for the tap is not available from the agents.

Good luck

2002 yamaha wolverine 350 4x4 fuel mixture screw has to be adjusted way out to run right carb is clean and if turned out 2 turns it will pop in exhust and cut off when you stop. Cant turn out enough to...

turning the screw way out makes the mixture lean, so the problem must be the carb is too rich.
check all the jets were installed correctly when the carb was cleaned
make sure the carb float bowl is not flooding.
Check the fuel tap is working correctly.
make certain the airfilter is clean.
check the engine has correct amount of clean oil( not fuel contaminated)

1986 yamaha 350 ypvs F2 should the wheels be red if so what is the RAL number

The site below (although European based) has all the colour reference codes applicable. Yamaha are a parts bin manufacturer, in that they cobble necessary parts from different models and sometimes share a range of colours across a model, particularly fashion type schemes.
The second link is bikepics, make a consensus from all the models shown for your bike.

I'm interested in purchasing a repair manual for my 1989 rd 350 yamaha motorcycle. Is there an auto store, or any kind of store I can buy it from? Instead of buying it online. I'd really appreciate any...

first off what country are you in ???? the 1979 rd 350 was an air cooled engine, same as 250 . the 1989 engine was water cooled with yamahas ypvs exhaust valve both very differnt in design although some frame and body parts cross over.the manual for the air cooled is: isbn 0 85696 505 7 . i dont have the water cooled number but could find it you require. the rd was exported under various different names ie: rd , rz , ypvs and so on. you can contact me @ hope this helps.

This can realy tire you out too.

1st wiggel all of the wires check for burn marks.

2nd Fuse box check for correct ones have been put in.

3rd Spark Plugs just put in new ones low cost cost for brand new .Check to see if You have Spark
if you don't Get A tester And read the service papers .

4th most of the fuel is years old trust me you need to mix 25/50 of Avation with super TT olny with yamaha RD 350 .You have penzoil for two strokes stick to olny one .

5th Fuel line pull the whole lot out put a air hose down blow it out .Clean fuel filter down the line
Clean the Air Box

Warning some bikes dont like Engine start Some with YPVS..
Playing with the enging iddl switch is not realy recemeded if the Bikes Not Runing !.
The Center stand could be down some bikes don't go with the center stand Down ( Its a safty Thing )

Turn the fuel on wile clutch out this will un block a air lock in the fuel line
6th Look for the Steepest hill you can find ! Stick it in top gear And wile you Speed up Like Really Fast STAND UP ! And push your weight on the foot pegs .And Repet this you should be clocer in starting to 3rd Gear if not 2nd .Pull the clutch in If you Its just Getting The fuel in .

Two stroke oil

Use the factory " YAMALUBE " oil. Engine oil is not a big deal but you can't go wrong if you stick to factory products.
