HP2 Sport Clutch

Anybody had a problem or heard of a problem with HP2 Sport clutches?
Leaking seals allowing oil/fluid into/omto the clutch plates?

All boxers can get oil on the clutch plates when the output seals go, not something that's easy to check though....

Should this happen on a 6000 mile only machine? Is it that common on the 1200 range?

Only with a faulty seal, it shouldn't have worn out in 6k.

I've never tried to get at the clutch area on the 1200, but I assume just to check if a seal is gone is a big job, maybe involving removing the gearbox (someone else will probably know exactly what's involved).

If the HP2 gearbox is similar to the R1100S, then the rear seal on the gearbox input shaft could have failed. This is the area where the clutch slave cylinder and actuator push rod reside. It is why the clutch started slipping on my R11S - but at 50k miles. It is/was a fairly common issue.

The seal(s) on the slave cylinder may also have failed, in which case contamination will be clutch fluid.

Removing the starter motor is easy and will allow you to look at the flywheel/clutch area for damp oily stains.

Another option could be that your friction plate is fried!?!

#1 i took my 1100s starter motor off yeserday cos it is playing up and I was pleased to see that everything was nice and dry inside. I have previously replaced a boxer clutch when main crank seal failed at about 50K miles. 6k miles sounds a wee bit premature for a seal failure

Thanks for the responses. Parts bill to fix is looking to be about £150 plus a fair few hours labour charge. Not a happy bunny. After all this is a £16,000 motorcycle which is barely three years old. I have just paid £400 for its 6000 mile service last month as well.

that works out about £370 inc vat & labour. £30 bits.

Had my clutch slave cylinder replaced by BMW on my 13000mls 3 year old R1200GSA FBMWSH as a good will jobbie. It is a full days labour, rear subframe plus swing arm drive shaft bevel box assy off. Then the gearbox off to gain access. Not a cheap option but I only paid for the parts. You may have an indication by taking the starter motor off. Speak to your local and if they are as good as Wollaston they'll look after you. This is a documented problem on the 1200GS range affecting a small number of bikes, unfortunately I had one of them.
