Harley does shims in smaller increments if you want to get it closer to the spec mid-range. However, then you'll have Harley parts in your bike. You might find the urge to wear chaps, your bike will only get out on sunny days, all rides will end up at a dumpy bar, any ride longer than 100km will be considered long, and you'll start referring to your riding buddies as `bros'.

I think I'll check my 570 today. 17hours on it and only street SM riding.

Hopefully they are all in spec.

Re: 70 degree valve check/adjustment

One observation re the shims is that:
- the stock OEM shims were made of two materials, a gold color outer band ring and silver color inner.
- the aftermarket Harley Davidson shims were made from just one silver color material.

Does this matter? ie OEM more durable etc?

I'm good to go for next 15-30hours?

Hey Fizz,
I did not see the gold colour on the OEM Shims I purchased. Here is a picture of the OEM shims on top of a ProX Shim kit box. There could be a chance the dealer in Sydney sold me non genuine shims and I never knew, but they did come in a plastic bag with the KTM part number on it:


Anyone care to comment on the ProX Brand? Is it good or bad?
It does have made in China on the box, not always a good sign

Re: 70 degree valve check/adjustment

Davo,

the shim in your pic are identical in color the the Harley Davidson shims I bought. When I bought them, the dealer says he sells them to KTM owners all the time as they are cheaper and have them in smaller size increments, but I was wondering why the OEM FE390 etc shims (I pulled out of my bike) had a two part composite material - could mean nothing, could be something - we need to wait for a reply from a guru. Maybe mine were leftovers at the factory - in other peoples 70 degree engine bikes - are they two part material?

Re: 70 degree valve check/adjustment

Just in the process of re shimming my 49 hour 570 and found some of the hardening missing on the inlet rocker arm
where it contacts the shim on the valve.

I had that problem on my 09 fe450, local dealer didn't warrant it, claimed he had never heard of it before
new rocker was $150 from memory.....cheap compared to the new fuel tank i need at the moment.....

Re: 70 degree valve check/adjustment

Just checked mine at 60 hours.

Left inlet .12mm
Right inlet .10mm

Left exhaust .15mm
Right exhaust .12mm

So all OK for a while I guess. It's good 'cos I'm riding Sunday and changing shims would be inconvenient.

Thanks Davo for the pic's the helped, and I am a mechanic. Always nervous about finding scary bits that might give me problems, so for warned is for armed.

Re: 70 degree valve check/adjustment

Would the next person that replaces a stock OEM shim on a FE 70 degree engine, please report back if its two part in materials or not per my prior post.

Thanks
