[moto748]

In my last 92000 miles on Ducatis (36k on 750SSi, 56k on 748), I think I've had shims actually changed twice, once on each bike.

If my shims needed doing at 6k, I'd be concerned about the engine. I'd be checking rockers.

Theres nothing wrong with checking the clearances anyway. I think the lubrication system in a testastretta head is far superior to the old 4 valve/2 valvers and has eliminated the flakey rocker thing!

Whilst they are checking your valve clearances.......the natural progression on from here is to have the cam timing checked as well!

This is aimed at any of the Ducati specialist workshops/mechanics/dealers on here.....how long does it take to check the valve clearances?

Also, service schedule states they need to be checked every 6k miles. Is that OTT or are they likely to need adjustment? My bike is out of warranty, but due a service shortly.

I had mine done during its 2yr jobbie..........3000 miles!!! along with the cam timing............I believe several were altered! and the cam timing was around 4 % out on all 4 cams! Although to be fair the tolerances are quite large!

Had this conversation with my dealer today. My bike has now covered 6000miles, but in March the belts will be due. Question was, do I have the valves checked soon and bring the belt change forward; as it would be daft not to change them while it was apart, or go over the schedule and wait until March and have both done then.
Conclusion was, as long as I was not planning on putting more than a few thousand miles on before March it would be ok to leave. This decision was helped by the fact that the bike came from them new, and they knew that all the service schedule was spot on to date.

Thats almost eactly the position I will be in, in about a months time. Glad I am not the only one who has received this advice

I checked mine at 6,000 miles and had two valves total that were out of spec and needed adjusting. Funny thing, it was the left intake opener on both cylinders. Everything else was dead center of the specs!! I will always check them every 6,000 but odds are they'll never need adjusting again...from what I've heard.

(oh yea...2005 749s)

Exactly the same scenario for me too. March it is then!
