Nice-looking mule. Point me to more pix and why not do a trip report here
I've heard about the petcock problem though not had any. Looks like an unnecessarily complicated design for a carb-engine, with people talking about getting in the muddle with all the pipes when reassembling. I've half a mind to fit a basic 80s-era tap with a simple ON-OFF-RES and one pipe coming out. Why have anything else?
Came down from Scotland last weekend which became lashing rain and didn't miss a beat. I did give it a spray a few days earlier and the slightly longer DR mudguard may help. I think many front guards on modern bikes are too skimpy - 'function following form'. I intend to extend it still further with an inner-tube mudflap off the back.
Can't hear any knocking on mine - bought around 11 - now 13k but thanks for the oil change tip. I think along with gradual warming up on cold days, that's the best longevity insurance you can do to any engine - especially air-cooled. I suppose you head may be knackered but I'd expect that from a 60k-old GS engine.
Yes, there are a lot of dairy-based fittings - it is from the 'monkey metal' era after all and worse still - a Suzuki! Most have been replaced with Allens.
We modified the gearing as the motor has little low end grunt as it is, and our back-of-a-fag-packet guess at 42T (OE 44) was spot on, ie: same as standard. Front remains 16T, so scope for a 14 or 15 for gnarly stages.
Would a 17 or 18 not be better?
I specifically wanted to experiment with identical
but bigger wheels. Maybe it's getting better as wealth spreads but 17s are hard to find out in the AMZ
. 18s and 19s (in Asia) much easier. Also, my rationale was to carry one spare to fit both ends, and with the current Heidenaus
I suspect that would give an OTT range of 25-30,000 miles while still benefitting from some dirt road bite. I've found 19 front an optimal size for dirt and road (conclusion from riding a BM '650' twin in Morocco
last March - a great overlander, IMO, but £7-8k's worth...) so the back followed. Eighteen all round would have been the best for tyre availability but I like the 19" flat track look ;-)
No moto I know runs identical tyres, possibly some bikes from the 1930s and 40s? and I'm pretty sure Vespa-like scooters do. So do pushbikes and of course cars, so I concluded it's mostly to do with looks, low seat height or of course laying down 180hp between speed cams. GS is immune to these factors.
Same size clearly simplifies things on the road and I have to say that within the limits of what you can do on a GS5, I notice no difference in handling or roadholding with what would seem to appear a skinny back tyre.
