Your point being?
No I don't, the Griffith is gone too.
Point being that this thread was started by someone asking for advice from those who have serviced a speed six. As clearly (if I'm not misinterpreting the above) you haven't, your contribution added little value as you have no first hand experience. No I don't, the Griffith is gone too.
What you were alluding to was a thread started by someone else where no context was given, so it will never be clear whether that shim failed due to failure in its manufacturing process or another seperate variable. Hence why I called it out and pointed out that I didn't believe the shims would deviate as the manufacturing process predominantly used would dictate they are much of a muchness
Too many threads get diluted with hear say.

The shim quality issue has previously been brought up by a very prominent engine builder and I have no reason to disbelieve their recommendations - hence me re-affirming what Getsis had to say.

Good stuff, and just like to point out no offense intended. The shim quality issue has previously been brought up by a very prominent engine builder and I have no reason to disbelieve their recommendations - hence me re-affirming what Getsis had to say.
I'm on the fence on the shim thing. I have the kit and it was fine (wont really need it now as I have a FFF)and after investigating the manufacturing process was happy to use it. What we should remember with that thread though, regarding the prematurely warn shim, is the particular vendor who pointed this out does not supply shim kits, their main parts competition does, and they supply to those in the trade.... Interestingly the argument used was spring pressure. If you go on a bike forum they'll say never use car shims, they cant take the RPM!
One thing I would definitely avoid though is skimming shims, unless your confident of skimming it 100% flat you run the risk, albeit it small, of it coming out. So spend a few pounds for piece of mind.
Right,
Shims R Us..... I have found the only issue to be shims that are tight in the retainer and therefore don't rotate and wear along the line of contact of the finger follower. These need bin treatment, they can start to rotate and can be noisy one miunte, gap plus 4 thou then silent the next... arrrggghhh. Don't turn them over, you have less contact on the valve head so will wear quicker.
So don't skim, only clean with 1000 Wet n dry if oil has baked on, usually exhaust side, don't spin over and check they rotate. Hardness? The KTM ones seem fine to me but you may need thicker than is in the kit, if you have a late engine.
Dom has found soft shims and I am sure some are out there, but if you listen to your motor you will hear it and find them quick enough before harm done, so its just risk Vs cost. Simples.

Just finished a service on the Tuscan and have learned a few tricks already! Managed to get about 6.5 litres of oil out plus the filter so think that was good going.
What made me scratch my head was where the sump plug was on the engine.eventually I gave in and rang str8six who pointed me in the right direction... On the side,two inches up from the bottom on an angle... How did I miss that
The airbox is a bit of a fiddle but again I guess there ISNA knack.
Spark plugs were super easy but a little more fiddly on the rear two but nothing major. One plug was corroded on the outside so water must have been getting down the pipe so I made sure I did a good job of sealing the cover on.
Took me about 4 hours in all as I was being very slow and careful but good fun
