Both bikes shredded the shims. Discovered this in next oil change after just 1-2 hours. Decent size flakes that looked like stainless steel and are not magnetic... What are the taffy's shims made of? The shims are gone, but maby this is coming from somewhere else...
As I have said before on another thread put a 0.1mm shim under a spring is asking for trouble, as if it would make any difference anyway.

Should I have used the thinner ones under the originals?!?


If there is too much packing under springs, the springs get too much compressed and break, valves dont like hitting seats too hard eather?
Too little and valves hit piston?

How can i measure that the valves are opening right amount? I am worried did the springs machine stuff away from cylinder head making springs sit lower? (aluminium casting cant take pressure)


TooLongDidn'tRead: -06 FS650 everything is original.
Can I use original washers under DVSK kit springs instead of provided extremely thin ones, Or do I use them both?
Hello

I heven't used the 0.1mm shims for - I'm guessing 4-5 years? the 0.2mm shims are fine and I've had no problems at all. if you measure the thickness of the shim you will be able to tell. the SRK shims are 0.25mm and the DSVSK shims are 0.2mm.

if you have used a starter repair kit (SRK) THEY will shred out a shim if a jagged edge to the bolt can rip into the shim and the starter clutch starts slipping. other than that, I've not heard of the 0.2mm shims giving any trouble.

if you care to contact me I will try to advise you.

my second point would be that I gave you instructions with the kit I trust. admittedly, not in your native tongue! but when in doubt surely you should refer to these?

kind regards

Taffy

Hello Clive

yes it is, as I say I think it is since 2011-2012. I've NEVER heard of a single problem with the 0.2mm shims. I'll hold judgement on the above until it is clearer what happened.

Hello Clive

I last fitted the 0.1mm shims in late 2011. you had yours done in December 2013 so the answer is that you have the 0.2mm shims in and have no troubles.

this is why I am mystified by Husa Bergele's comments?

Husa Bergele
it might be that your mains are going? if they are the bike will spit the shims that create your crank float out.

as I say, I have had not one problem with the 0.2mm shims.

regards

Taffy

TY for fast response!
I have now opened cylinder head. The shims were 0,2mm, and they were quite squished and warped. Too much pressure... One was broken trough. Material was also magnetic unlike the stuff that was floating in engine oil... Time to replace bearings(or atleast check them)?

I hope I managed to get pictures attached.

Last picture with new shim and the "used" one was taken while ago from another berg

Bike has now 270hrs.

The washer/spacer that comes with the Kibblewhite spring set are around 3mm thick.

No chance of that happening.

Very interesting and not surprising at all

I tried 0.1mm shims under taffmeisters springs in order to try and get them to do what they were advertised as doing (reducing forces)

It didn't work. Whenever I posted as such There were posts claiming that there has never been a problem with the 0.1mm shims

Now we see the same claim about 0.2mm shims.

It's the same as the claims about the seated forces of these springs .... Complete BS

The reasons it doesn't work to use 0.2 instead of 0.1 is the 0.1 is not thick enough to fatigue under deformation. Ie they are basically so flexible they do nothing

The 0.2 mm steel is a higher stress situation and still not stiff enough for the job

Difference is that it fails rather than just being useless

As I posted 5-6 years ago the lower spring seat should be a minimum of 0.4mm thick with a Rockwell hardness of 2 points higher than the springs

Like the Ktm set or the kibble whites

The original spring seats that came with my taffmeisters dvsk were zinc plated mild steel washers from a hardware store. The shape drilled in the middle wasn't round or even in the middle.

Basically the only difference between the Ktm set and taffs set is the thickness of the lower seats and the price

If you want readable instructions easy fit and a product that does what it caims to do just get the kibblewhites
There has never been an issue when installed as per their instructions lol
