Well ... swilled out and emptied the the tank on the R80RS with some petrol. Then did the same with the float bowls, filling them with fuel before popping them back on the carbs. Attached a car battery and jump leads. After about 10 seconds of turning over the old girl fired up! And settled to a good if slightly lumpy idle. Not bad seeing as it hadn't run since about 2000 or so! So now on to full service, sort out the brakes and a good front to back clean Went to the R45 and did the same .... but it wouldn't respond to the start button so either the relay is not working or there's some other electrical gremlin. Given its not fired up since about 1992 it's allowed to be grumpy I guess -- Steve Parry BMW R45 01 Kawasaki ZX12-R 07 K1200GT SE 95 BMW F650 87 Yamaha FS1 Sukida SK90PY 91 Kawasaki AR50 07 VW Passat SE Estate for comfort www.gwynfryn.co.uk
True. Of all the things[1] that I've had go wrong on airhead boxers, carbs have not been among them. Mind you, it's a mono, so the coil will be cracked and letting in water. [1]Valves losing their heads, big ends going to ratshit, clutch, starter motor, loom, a succession of oil pressure switches, rotors, partial seizures, cracked subframe, aforementioned coil etc
I gather the 1000s are more fragile, mind. Summat to do with all the airheads using the same bottom end, was over-engineered in the R50 with about 35 BHP...
I don't think the problem with the 1000s is really to do with the engine bit. If the 1000s have probs, it's usually gearbox-related (same gearbox fitted to everything from the R60 to the R100).
It should only be very slight though. We tried lots of things in the 80's with the iron lined barrels and decided that occasional cleaning was best! The nikasil barrels can be properly oil tight.
But can't be rebored... hmmm. worth a shot I suppose: if anyone has a decent pair of airhead heads, I'd be interested. Mine have issues with valve guides and valve gear (some of the rocker bearings are not what they might be) - it's either replace the heads or get them refurbed properly... 'course, I could fit 750 or 800 cc barrels and pistons at the same time with little extra work
Well .... a long time back I had a conversation with a plod bike mechanic who reckoned they'd mic'd up some barrels from a very high mileage nickasil bike and there was virtually no measurable wear so reboring isn't really an issue. Just get in touch with Motorworks, I'm sure they'll have all the bits you'll need.

yeah, but they'll want money for them. more, probably, than a half-decent s/h pair. Yep. To be fair, it's still running, but it's losing a bit of power and smoking on the starboard pot.
