check www.bikebandit.com they have parts for older bikes. They can be a little expensive though, but at least you will see part number.

hi,i am guessing you have a gs850g,if so the diff housing has two holes,one for draining,and one for filling,the lower of the two is for draining ,the upper of the two is for filling,to drain the diff oil simply undo the bottom of the two plugs and let the oil drain out,to refill simply replace the drain plug,undo the upper of the two plugs(this should be a relatively large one)refill with a good quality (normally 80-90w)gear oil,(the diff should hold about 400-700mls depending on model)simply fill the diff housing with oil untill it starts to dribble out of the filler hole(this is the correct lubricant level),then replace the plug,thats it ,very simple,i normally do the one in my 650 katana about every 30000km,to my knowledge there are no other lubrication points in the driveline,except the axle spline shaft which slides into the universal joint at the back of the gearbox,but this is normally fairly maintanence free as it is sealed from the environment by a fairly substantial rubber boot and shouldnt need looking at unless the rubber boot has been split or has perished,,hope this helps

Something very faulty , you changed pickup coil, but looks as you need Diagnostics , to find out 100%

Where is the Red Line for it? If you pass the Red LIne, it is supposed to cut on some models.

Head gasket?

It sounds like you just need to flush your engine and clear out the sight gage.Get some good motor flush and a can of Marvel Mystery Oil. Go ahead and pour in the motor flush and Marvel.Run the bike at idle and about 2500 rpm back and forth for about 5 mins or so constant.Then drain it all out and replace with clean oil and filter.That should clear out whatever gunk you have in the engine.

Before replacing it, check the tensioner...it may be broken. Also check the guides. Make sure the cam sprockets aren't loose or cracked.

Hi there,

Well, the oil filler cap is located on the left side of the your bike, check at the downside of your bike (upside to the back breaks). you can easyly open it up by hands.

Good Luck!!

Thanks

This is a highly ill - eagle act to do. In the old days we would put an electric drill on the drive cable, but now they make them tamper proof so they only go one way. The bezels are crimped on so you can't get inside them. I expect modern one may be electronic. How will your insurance company know what mileage you have done? I have never known an insurance cancel or fine due to mileage. You should have just disconnected it when you got close to the limit. Buy a used one and use them for 6 months in turns.

Make sure the fuel is getting to the valve and passing through it. Possible blockage in fuel line or in the tank.

It isn't called a Magneto, that was for really old bikes. It is a 'stator'.
