SOURCE: engine backfire
try pulling the choke out a little and see if that doesn't help. If it does that is a sign that you are running too lean and need the jets in the carb increased or just the air mixture screw adjusted. If the coke test doesn't help, please tell me more about how and when it acts up. Like after the motor is warmed up does the backfiring quit?

On the right side of the bike (right side when ou are sitting on it) just above the rear brake lever behind a small circular plate. remove the plate and the oil filter is inside (you will easily see it). Warning---on these bikes you have to drop the front exhaust header and right floor board in order to change the oil filter unless you install a after market oil filter relocation kit. If you plan on changing your own oil it is highly recommended to install this relocation kit.

It is part of a detent mechanism for the choke. No, all 4 carbs do not have them, only 1.
Here is a link to Yamaha's website, where you can pull up a diagram of your bike's carbs. The ball is #10 and there is also a spring with it.
They are saying there are 2 balls and 2 springs, but I do not remember them having 2. I also don't see another #10 or #11 on the picture anywhere. You should be able to look at the rod that connects all the chokes together and see if there are 2 sets of dimples for the balls. Obviously there will be one set in carb #1, if you find another set of dimples for a detent ball, then there indeed would be 2. Also, the carb body would be drilled for the spring and ball like the #1 carb is.

These parts are fairly reliable. Rather than buying new, you should be able to pick one up from a motorcycle breaker who will post it to you. I would expect to pay about £60-£100 tops in the UK (Depending on mileage). ANy Yamaha dealer will be happy to order you one new, but they are a hell of a price!
