Finally had a chance to do the valve clearance check and they seem to be out of spec. These are the clearances i got.
Front Cylinder Intake - .004 .0035 Exhaust- .007 .007 Rear Cylinder Intake- .0025-.003 .0025-.003 Exhaust .007 .007 On the rear cylinder i had .0025-.003, the .0025 was going in easy but the .003 wouldnt go in so its inbetween the two. Bike had done 31k miles and not sure if it was done at the 15k interval. Where can i get shims from? Is a kit better to get rather than individual? Thanks in advance |

I have heard that some dealers do a swap on shims, you work out what you need, take your unwanted ones in and pay the difference, any orgers had experience of this or was the bloke that told me talking b0ll0x ?

you will have to convert those numbers to mm so you can work out the shim sizes to be ordered.
yes some dealers do indeed do a shim swap service, more so if you are a regular. |

Is it best going in the middle, so intake is meant to be between .004-.008 so should i go .006

I have a few spare shims, if you tell me what you need, and what you have to swap, I will see what I can do.

You need to know the sizes of the shims that are already in. When you have the table, you look up the current shim against the measured gap and read off the new shim required. Aim for the upper half of the gap range i.e. looser rather than tighter, but if it's in spec then don't both changing it. So, it's a bit of a faff as you need to take the camshafts out to find out the shim sizes first, then if you're going to ride the bike you have a fair bit of reassembly that's going to be undone when you get the new shims. Once they're right though they pretty much never change.

If you can have it off the road for a few days whilst you get the shims you need, just buy what you need. As Johnnyrod said, unlikely to need doing again unless you do big miles. |
