Re: 99 intruder 800
There is a universal joint in the drive train that can go bad. It may require you removing the drive shaft side of the engine covers but you can access it yourself and I suspect you will see the problem. You're not having any problems with the bike in any particular gear are you? If you like to DIY I can send you a very good link to a website that has exploded views of your engine and the parts you may need. You can even purchase the parts from these people at a very reasonable price. Just let me know if you need further assistance. Regards, RSelvy

Put the bike up on the main stand. Remove the rear brake caliper assy. Loosen the rear axle and pull it out. Now pull out on the wheel, pull it away from the rear gear housing, the wheel will disengage a gear inside and then it is ready to pull out the back.
your cycle is quite different from a car in that the engine and trans(gears) are combined..so the same fluid lubricates and cools the bike....
being a v-twinn there are good oils out there today and much more inexpensive than before...
in fact many local auto stores and even discount stores have cycle oil...just make certain you get a quality brand like: valvoline,mobil,castrol and for your twinn i'd try a good 20w50.....check your manual for quantity and change the filter as well...some stores are even stocking cycle filters....
this sounds like a bearing in the gear box on the lay shaft maybe prop the bike up on a satnd and run it up in gear to here the gear box working
ps,,,dont let it fall off the stand when its running up!
hi this may help,this si quite a common complaint on shaft drive bikes,what you are actually experiencing is the torque reaction between the drive shaft rotating on a horizontal plane and the crown wheel rotating iin a vertical plane,as you crack the throttle open the back of the bike wants to stand up and off the throttle the back end will squat down,some of the earlier bmws were like riding a pogo stick,they were very bad for it,stiffening up the suspension may help a little,but it will still be there,unfortunatley it is a problem that is common on all shaft drive bikes(my gl1200 and gl1500 goldwings both do it so you are not alone...hope this helps
Main drive gears. The bike is pretty old, so there is undoubtedly a wear pattern on the faces of the gears, especially the higher two gears. The crankshaft bearing may also be worn and need to be replaced. Does the engine whine only when the gears are engaged, or also when running in neutral?
if the belt is too tight &/ or misaligned, it can make nasty squelching noises!?? I found that the cush-drive hub runs on only a single bearing, off-centred to the belts pull, which could not maintain radial/ alignment stiffness, this made all the square teeth on the belt wear to a taper, i eventually had a secondary 'outrigger' needle-roller bearing mounted on the far inside end of the cush-drive hub [this took a little specialised machining] and the new belt since, now wears true!
