look for case hardening damage or any bearings or surface breakdown
piston gudgeon damaged
out of balance if its a two piece shaft

My bmw f650 just cut and i cant seem to find the mechanic checked the plus,fuses and only managed to get it crunking but wont start.what could be causing this?and some times the fuses get burnt.

Pull one of the spark plugs and hold it against the engine with a non-conductive tool and have someone crank the engine.Is there spark?No spark indicates a possible timing problem.If you have spark squirt some fuel down each cylinder,put the plugs back in and crank the engine.If it barks you have a fuel delivery problem and that on a BMW means bad fuel pump or plugged injectors.There really isn't anything else on the bike.You don't say which fuses burn out,but let me know if its the fuel pump because that would make all kinds a sense.Good luck and hopefully good riding

How to removal the shaft from the rear end to


In order to remove the rear wheel, it is not necessary to remove the drive shaft. The first step is to get your rear wheel off the ground. The easiest way to do this is to put your bike on its center stand. However, not all bikes have center stands. If your bike does not have a center stand, you may want to buy a motorcycle lift (available from Pep-boys, or Harbor Freight). Once the rear wheel is off the ground, you can disconnect the brake linkage, and then remove the rear axle.

At this point there is nothing holding your rear wheel to the bike except for some meshing gears. Now you must lift and maneuver the rear wheel back and forth a little and eventually the final drive will work free. You will be able to slide the wheel toward the right side of the bike and then lower it to the ground.

In theory removing the rear wheel is that simple. In practice, the gears in the final drive can sometimes hold on quite tightly. This is particularly true if the rear wheel has not been removed for a long time or if your final drive is very worn. Usually being patient and persistent will pay off and you will be able to remove the rear wheel.

Sometimes it may prove easier to remove the entire wheel / final drive / drive shaft assembly first, and then separate them. In this case, the order of operations is different. Once you have the rear wheel off the ground, you can disconnect the rear brake linkage just as before. Next you can remove the four bolts that hold the drive shaft housing to the back of your crank case. Finally you can remove the rear axle and slide the wheel backwards the unmesh the drive shaft.

Regardless of which way you remove the rear wheel, it will be easier to put it back together by first attaching the drive shaft and final drive to the crank case, and then reinstall the wheel as described in the first method above.

Good Luck,

Car wont start

Is it crunks but not start or it not even cranks.
If it first check spark plugs/wiring, distributor cap/rotor, colant temperature sensor. To figure it out first try to heat the car engine block with fan to see if it will affect anything. If no good check fuel lines too. If car won't crunk at all it can be starter or blown fuse.
For starter check the wiring comong to it, you can just move them a little, it might be just they are not tight enough. Let me know if you need more help
Good Luck

My sons Dr250 Suzuki's gear leaver shaft has slipped into the motor and has no gears, I can pull it back out to its original position to select gears, the question is what is supposed to stop the shaft...

I believe that on these models the retaining clip is internal,and the shaft seats into a bearing at the other end. If the bearing has come apart it will allow the shaft to slide in and out also. Drain and check the fluid for metal or excessive shavings. If it were external, you should be able to see the groove for the clip with the shaft pulled out. Most likely, you're going to have to pull the engine, and split the cases to get to the tranny in order to fix the problem. Pain in the arse, I know, I've done it a few times on my dirt bikes. Assuming this is the DR250 enduro style dirt bike I'm thinking it is. If I'm wrong on the bike type let me know, and I'll see if I can get more info, cause I believe Suzuki also made a DR 250 S in the late 80's or early 90's, which was a sport bike.
