So I checked out this problem on Google. As I spun the wheel the belt corrected it's alignment. I rechecked the wheel alignment, fine. But the belt spindle has lateral movement.

Hi Gavin

Contact Ruan at Cape Bike Travel...I think the wheel bearing is shot...

Thank you. I kinda hope it isn't but you are probably correct. Damn!

i don't suppose it's safe to ride too much until it is fixed.

But, if it is the bearings it is likely you could have a catastrophic failure with the rear wheel locking up.  At best you will need a trailer to pick you up and take the bike to be fixed.  At worst...

I have just read an article where the author (an experienced BMW and KTM rider) says that if there is any doubt about the health of your wheel bearings, just replace them - the cost is worth it for the savings in inconvenience and feeling of helplessness when they go while you are out on a ride.

I am a qualified Bmw Motorrad Technician.The rear wheel pulley may have a minor lateral runout.It is a cast part and not machined to zero tolerance.The way to check the wheel bearings is to have the bike on the main stand.Which u should have on the ST.And sit (crouch) next to the wheel,where u see the complete inside of the rim and the rear wheel pulley.Place one hand at the bottom and one at the top try to wedge the wheel from side to side.If there is movement the bearings is probably shot.

Check your belt tension belt tension.About 35mm of movement on the bottom in the middle of the swingarm.And that the cover is not chafing the belt.Either of the two could be the reason why the belt is migrating.

Hope this helps!

I owm a 2007 F800st, 35000km, I have been to the Buff Rally and found gear change difficult, almosts as if it hooks going into gear. I have serviced the bike myselfwith a K&N filter, Denso plugs with 10k, new oil filter and Indy Oil 10W-50

I would appreciate if ther is a problem that is need of attention, or that i am to sencertive on the toa that has been hurt befor the weekend.

Thanks

To say big thank you for all the feed back and support I received on my F800 ST belt drive. BMWMCC rocks.

Mine is at 80k and gear change is intermittent but I figure at this age I must be super caring in gearing. Bike gearing to me has always had occasional gear hooking.

Hi there.the two obvious things to check is that the gear lever is tight and that uve got freeplay on your clutch lever.u could always move the gear lever,maby the angle is not sorted for your boot or foot movement.with that mileage you could put a fully synthetic oil in.which i make out youve already done?that could help but is not a guarantee.otherwise its not impossible that the gear shaft is bent or that the gear selector drum is worn its sharp edges away.just make sure about the first few things mentioned,the obvious.

Thanks for the responce. I believe that Indy Oil 20wX50 is not the best for this bike and that I should be using SOS 20wX40 which is the standard lube used in BMW workshops. Synthetics is not recommened.

Not officially by BMW Motorrad perhaps, because they have their own deals with oil suppliers and have done their own testing with a subset of oils available.  However, some of the very best BMW mechanics in this town recommend some synthetic oils.

My 2001 1150GS is on 200 000km, and has been on fully synthetic oil for the last 70 000km.  The bike commutes, does long offroad tours, and some extreme riding under extreme conditions.  Gear changes are great, and I only use the clutch when pulling away or stopping - not for up or down gear shifting.

My 1998 650 Funduro is on about 140 000km, with a wet clutch, and also runs on fully synthetic.

So perhaps you want to reconsider the selection of oils available to you.
