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
You just heat the part where the bolt is screwd in with loctite to about 150°C and you will be able to loosen the bolt with no problem...
(By the way, almost every manufacturer uses a locking agent like Loctite on safty parts as the bolts on brakediscs...)
Did you degrease everething properly before applying loctite?
I would try loctite 270 (high strength) before I start drilling holes in the shaft (and making it more fragile).
Maybe these pictures shed some light to your problem.
And if you look at the picture below, you will see that at least the outside of the silencer looks standard (could be a titanium copy or something like that of course):
And may I ad another thing in the mix (haaa... ha... ha..... ha)
Does anyone use alkylate fuels as I do in my four-stroke?
Should run a lot cleaner (and better for humans and the environment), also in two-stroke engines...
