Re: Coming up for Sale

Hi re Stews Gp for sale , this used to be my old bike, I owned it for four years having bought it with 6k on the clock, I looked after it very carefully and never had any issues with it, apart from the not very good standard mapping. I have seen the bike recently in Stews ownership and he has upgrad...

Re: Nothing like it since...

Our bikes have the lot, great balance at low speed, sometimes you can almost balance at lights, low curb weight, large tank. Lots of power, well designed high tensile frame and good suspension at least at the rear suspension . The engine is a masterpiece of design and in use, what more can I say, mo...

Re: Swing arm failure

Hi all After some thought and discussions with various experts in aluminium welding, it has been decided not to brace or reinforce, the welds on my swinging arm, they appear to be perfect and the chain tension issue I believe may have contributed significantly to the issue. I am right back where I w...

Re: Swing arm failure

Hi mysterG I have been talking with an aero space engineer friend today and it seems it’s possible to weld our swinging arms for additional bracing and to repair existing ones . I am going to get mine crack and dye tested first just out of interest. Really only bracing with 3mm 620/720 alloy plate t...

Re: Swing arm failure

thanks for posting pics , looks like a catastrophic break as opposed to gradual , which is scary. who is repairing your swinging arm, and how are they going to do it reliably, being a thin wall casting. I did think about seeing if it is possible to add bracing to the pivot points on the arm, let me ...

Re: Swing arm failure

Hi Ogri I have just had a dig around, you might have a thermostat malfunction, its staying closed and not allowing the full flow and consequently the correct fluid level /amount, there is a coolant sensor on the body which will still give you a temp reading but will shut the engine down if it gets t...

Re: Swing arm failure

Sorry to here your difficulties... lets not forget these are ageing bikes now and need tender loving care, they where never the equal of a Honda or early oil heads and need to be checked looked at each winter, being very small production hand built machines with a tiny development budget. lets not f...

Re: Swing arm failure

Hi Very sorry to here this , you have been very unlucky in the failure and very lucky in the outcome. Good call on getting back on the road, they are without doubt one of the best bikes / adventure sport bikes but the hydro forming was an early application of this technique I believe. I am on my sec...
