see if you can hook the seal out and replace if not then remove the cover and that mite mean stripping engine ! ?

I would check the stator to see if it's grounding out against the case first. If the stator checks ok then it might be residual just burning off. I’m happy to assist further over the phone at https://www.6ya.com/expert/robert_5bac37c3cb991fdb

there may be a problem with the clutch not engaging---make sure the cable is activating the clutch

serch your model and buy the service manual to fix your problem

You should check oil and if your bike is liquid cooled check coolant. check chain tension and get a tq wrench and go over axle bolts, brake bolts, tree bolts, drain plug, ect all these specs can be yours from your dealer. also check for any leaks.

Yes. you may need to make some engine mounts to fit the new engine to the old frame, but you will also need to transfer the electrical harness from the RM to the TS chassis.

This may help you determine the problem.1. is sprkplug oil fouled? wet? dry? superhot and white electrode?A sparkplug will always tell you whats going on.if its too wet then its not burning all the fuel and oil and flooding out.if its extremely hot and white, then its running lean , and needs more fuel.also make sure your running 50:1 fuel oil mix.a hot two stroke is hard to start.if plug is dry, then its not getting enough fuel.2. make sure your fuel oil mixture is 50:1.to much oil is okay but it may smoke alotway to much oil will oil foul the plug and plug will have oil on it.to little oil will make the bike run hot and start damaging the bottom end crank bearings as well as your rings , then piston and cylinder walls.the plug will be whitish and hot.3. as for the timing , the rotor is resting on a keyway on the crankshaft and will only move out of time if the keyway is sheared.4. make sure you have good spark when bike wont start.a coil that is going bad will work cold but may not when it gets warmed upto sum it up check to make sure you have correct fuel mixturecheck you sparkplug to see how its burningmake sure you have good sparkif you have good spark, good fuel, good compression, then it should start within 2 kicks everytime.i have a blaster 2 stoke 4 wheeler, starts everytimesince i rebuilt it.i hope this helps you out and you can enjoy the rest of the summer with your dirtbike.best regardsBig Al

sounds like worn piston rings. In 1st ans 2nd gears the engine wants to rev highest to make maximum powere so rings get a bit worn and oil will be sucked past. Change the rings and try again

The timing is preset from new and is not usually needed to be changed, even if it was out there would still be spark, just not at the right time. It could be the coil or wiring.
The stator make the electrical power not the spark, a small pick up coil triggers the main coil to spark

Yes you can; but it is a very good idea to drain your carburettor(small phillips screw at the bottom of the float bowl, sometimes an allen screw) with the FUEL OFF at the fuel tap at the bottom of the tank. Then remove the fuel line from the tank to carby at the carby end, and drain ALL the fuel out of the tank(ensure to switch the fuel tap tap 'reserve', if applicable). Actually it's a really good occasion to remove the fuel tank completely, and rinse it out with a cupful of the new fuel mixture; but I don't know how committed you are to maintenance...If you don't follow this procedure to separate the two different fuel mixes, you may get partial solidification of some components of the fuel/oil mix. Then again, nothing may happen: but it is better to be safe than sorry!

I seem to remember having an issue similar. Try this, ...
With the cases around half an inch seperated, spin the counter shaft sprocket shaft while working the halves together. This will "mesh" the gears better. If this doesn't help, you may have something out of order.

The motor is not meant to run backwards try rolling it forwards and pop it in 2nd gear. Good luck

Move the clip on the jet needle downward. This effectively raises the needle so the low end gas supply begins sooner. Please rate my answer.

Dont disassemble the caliper, just yet.

Bleed new fluid through it.
Check the disk isnt bent

If your bike is water cooled there is a broken oil cooler in your rad. Some bikes are oil cooled and the rad is actually for a 'oil cooler'.
If it mixes with the water it usually turns into a milky brown substance. New rad is needed (or cooler repaired)

no.......

The swing arm is a really solid piece of your bike. Did you bend it? I guess anything is possible but more likely is a missing spacer. Check your re-assembly and see if all parts are present. If they are all there, then the only thing left is indeed a bent arm. It is an old bike, so find a good sized vise and bend it back. A machine shop would have one. Heck, they would probably charge you $10 or less to go ahead and bend it for you. Alternate to that is to google motorcycle salvage suzuki and see what you can find. Please rate my answer. Thanks.

I would pull the head and then de-carbon the piston, head and exhaust port. Red hot carbon can ignite the fuel prior to the spark plug doing it. At the same time I would check the cylinder for scaring due to partial seizing of the piston. Is the two stroke oil in the gas too little? With too little oil in the gas the cylinder and piston will overheat. Please rate my answer.

Many wheel chair riders are my hero. The side cars they build that they build to roll there wheel chair into (the ramp flips up to help keep them in place) and the full set of hand controls that they mount on the motorcycle handle bars in front of them allows them to ride in a way similar to the way I get to ride. Unfortunately, they do not get to lean into corners. But you do get to see a few of the riders at Sturgis, South Dakota each year. If you do not have the ability to build your own , you can see if this fits the bill. http://www.mobilityconquest.com/index.php
