cdi unit out or wireing prblem

Check the carbs remove the bowls and feed fuel to the rail check fuel flows from the float needle when the floats are dropped, also remove main and pilot jets blow through with compessed air to make sure they are clear blow out all passages ,check idle mixture screw is set correctly start 1 1/2 - 2 turns out and work from there. Check tick over is set correctly.

check your diff lock lever. you cant run in hi gear with it unlocked.

Things to check. Is the chain adjusted correctly and is the rear axle tight. With the rear wheel off the ground can the wheel be rocked around on the axle (Are there bad wheel bearings?). If you still have the problem after these checks, raise the rear wheel off the ground,take off the wheel, unbolt the shock (check mounting bolts for looseness), grab the rear swing arm to see if it moves or wiggles at the pivot points. You probably have bad swing arm bearings. If the swing arm bearings are bad you will probably have to change both bearings and the long inner bushing to fix the problem.

You must make sure that any other cdi unit is compatable with your make of bike .Best advice is to obtain the same as fitted on you bike ..check the unit model type rating and output .

what year is the Bike?

Spark plugs. Or the coils. Just because there is power going to them doesn't mean they are working. But as they are fired by the CDI unit you might like to look there. Mine was a failed coil. If the problem is on both coils, it can only be the CDI.

it could be a bad/dirty earth try going along the wiring loom with a multimeter staring from battery and work your to the headlight

CLean carb take fuel off and clean needle is stuck in carb might need carb kit mopar Kenny

I don't remember the quantity but if you go to Yamaha Auth. service center they have a small plastic box of fork oil labelled as Geniune Yamaha Suspension oil and the whole box is poured in one fork. So you will need 2 such boxes if you are servicing both the forks.

Hello
The main jet size should be 2 wire drill sizes larger (measure to the closest wire drill size as a starting point) to start for a 4 into 1 exhaust system, There is no one size fits all, you start with drilling it out the 2 wire drill sizes (set is 1-60) and see how it runs. Do not go more than 2 drill sizes larger as a base line. I have done this on at least 5 of my Japanese bikes.

did you turn the fuel on?

If the clutch is working as it should, the shifting problem is unrelated to the clutch. The bike has a bent shift fork or two. It is costly to fix. Below is a diagram of how the shift drum moves slider gears to change gears. If a shift fork is bent, it doesn't move left and right freely. Please rate my answer. Thanks.

100 mm is 4 inches out of line....thats severe.
Is this a chain drive bike...if so the swingarm slots the axle runs through often have marks so the axle is even on both sides.
