F800 tubeless kind of

[JJH]

Ok I have a f8GSA which I love except for the only downside - tubed tyers. I've read of various solutions which seem to cost a fortune. So with new tyers needed I got a pair of those new Michelin yolks. Also needed front pads replacing and wheel bearings on rear. She is out of warrenty so I was doing it myself. Tools ready and a few extras tubeless valves sicoline Denso tape and some duck tape. Out with back wheel replace bearings clean rim sicoline spoke ends let set over night.
Next morning wrap Denso tape starting and finishing with a overlap at valve. Next is 2 layers of duck tape. With drill bit in hand make hole for valve and slot in valve screw nuts quite tightly. Put on tyre with PLENTY of lubricant and blow up. Tyre seated grand on right way round never balanced before why start now? Fit wheel and check for pressure drop none after a week. Next job front wheel brakes sized both capilers fuck. No luck with a few friendly taps and prys. Remove capilers put into vice after a lot of various desperate measures out came the blow torch. Success at last. Brakes sorted now for tyre done everything the same except I wrapped everything in the rim tape. It leaked from whatever I don't know. Now has a tube. Might have another go. It's got 600 km on since.

Only difference in rims apart from size is that rear appears to be a safety rim and the front doesn't appear to have the same humps around the central valey. Jjh

I'm more than happy to answer any questions or suggestions you might have. I used Denso tape about 30 years ago on gunbarrel gas lines that were buried under ground. I recon if it's good enough for that it would do me. The main techiconal reason for duck tape was to help prevent the Denso from unraveling. The valve going trough at the overlap should help. For the life of me I could work out what centrifugal force would be working on it other than it would be negitave. That's why I put the rim tape on the front. I doubt if that's what caused the leak. I might have another go soon. Any suggestions welcome. Jjh

For those of you who are wondering why I didn't look for warrenty from BMW well I was fitting some pads I bought for £35 for 3 sets at the NEC last year and while I can be a bit cheeky I don't have a brass neck. Same with wheel bearings €25 not worth while. Bike is 2 years and 2 weeks old with 30000 miles on it If I'm to get any good will I don't want to waste it on that. Jjh

I think there's been a thread recently on going tubeless with the f800 interested to see how you get on with it as it's something I want to do as I'm about to replace the tyres
