Hi Andreas,
For parts in Belgium you can have a look here: http://www.snezzy.be/
They specialize in old-timer parts, are very helpfull and are located in Trooz, south of Liège.
Good luck and a lot of fun with your bike.
It sounds to me that you're already to much forward on your bike when you land...
I had this once dropping of a rock, went over the handlebars and landed on my shoulder
I now shift my weight more backwards, maybe you should try that too...
I also weigh over 14 stone (91kg) and I ride with the standard spring, only with the special linkage plates. Had no problems so far...
Maybe I should consider the heavier spring....
Dag Eugenevd, ik kan uw eerste zin ook lezen zonder problemen. En ik ben een vlaming en spreek vlaams ;-)
Hi Eugenevd, I can read your first sentence without nay problems. And I am fleming and speak flemish ;-)
No, at least in Belgium it's not availeble at the pump. It's mostly sold in garden centers for use in lawnmowers etc.
I use the Aspen 4 (euro 95 RON octane) fuel in my 4-stroke. But it's also available in a ready-to-use 2-stroke mix

Aspen has racing fuels also: Aspen+ ( 98 RON octane) and Aspen R ( 102 RON octane)
They even sell Aspen E which is a bio ethanol based racing fuel
