Not exactly the solution I was hoping for. But yeah, I guess they are not too serviceable.

I have a 2012 ST290. I looked in the service manual, and there is a reference for removing and re-packing the silencer packing fibers on the newer models However, on the 2012 model, I am not sure this can be done. It is of a different design than what is shown in the manual. On my bike, there IS a philips screw in the correct location that would indicate it is possible, but when I remove that screw, nothing comes apart. Does anyone know if the silencer tube can be removed for cleaning or repacking on the 2012 model?

Good points. I'll give eBay a go. Can't imagine I would find anything like that there, given the scarcity of the bike.

I am seeking a lighting and electrical wiring kit stripped from any of the ST250 through 300 series. Lights, taillights, horn, regulators wiring harness all welcome. I'll pay top dollar in the USA. Don't ask why....I just need it to get licensed...then off it comes again. Lemme know Phil

I like your suggestion with the cam. Thank you for your help.

Adding 2mm to base gaskets will also change the port timing slightly, whereas increasing the head gasket will not. Is it your recommendation to lower compression AND change port timing by using a base gasket, or just to lower compression by using a head gasket?

The throttle on the 2012 is WAAAY too scary. Comes on way too hard with small throttle inputs. What methods are there to calm this beast down? 1) What alternatives are there to slow the throttle cable twist grip? I use the Domino side pull (slow) trials version now. 2) Changes to timing? Advance or retard? 3) Changes to cylinder compression or gasket thickness? 4) Changes to ignition mapping available? 5) Porting mods? 6) Reed mods? 7) Cylinder alternatives? Is there a 250 piston/barrel available that will fit on the 290 engine? I am 65 years old and a expert-level rider in my previous life, so don't give me this "You gotta train harder and get used to it" approach. I don't want to shoot up and over 15' vertical steps...I just want to slow things up a bit.

It is impossible to bounce the rear on the 2012 . Can't even get it off the ground no matter what I do. Front brake is clean and acts like a trigger on a gun, but still won't lift the rear end. Damping is WAAAAAY too slow. Sag is about 10-15mm with no rider. Is there any damping adjustment on the stock 2012 rear shock and where is that bugger anyway?
