Valve Check every 12000km

So im due for the 12000km service on my F3 675. I phoned my dealer and crapped when I heard the cost (7 hours labour they said).

Decided to do it myself, but it literally requires taking every single fairing off, fuel tank and airbox to get to the top of the valves. And then also lifting the bike up on its front wheel which Im hoping to get away without doing.

For those that have done the service, how many of you required shims on the valves? That is the one part, if required that I wont be doing as it involves removing the cams so best to leave that to the dealer if needs be.

Oh and is there oil behind the stator cover? it shares it with the cam chain so not sure (just want to be ready for it).

This seriously puts into question the touring MVs if they have such finicky service intervals. I see Yamaha R6 has this valve check at 26 000 miles and the other supersport manufacturers at 16000 miles. 12000 km is ridiculous!

That time must include R&R the cams to make shim changes. Should NOT be 7 hours just to check clearances.

You could do it without lifting the front of the bike, just not as easily or without spilling some oil out of the cavities around the valves when the cover comes off.

All bikes there days have the same base materials for seats and valve faces. The valves are what wear, not the seats. High RPMs and dirty air generally cause valve face wear, which causes valves to tighten up over time. Loose valves in shim type systems are caused by deposits. Blame crappy fuel, or over rich mixtures, or too much low rpm running.

My 910R, Gina, has never needed a valve adjustment and is well over 24K miles now.

Had my bike in dealer B800 for valve clearance at 7,500 miles (roughly 12k), all were well within spec, no shims needed.So rest easy it will not be as big a job as your worried about. If they are out of spec yep 7.5 hours for full service seems fair. Keep your fingers crossed.

Now mine is out of warranty I will be doing it myself next time, no worries.

Had mine checked @12,000kms all within tolerance. With many track days in that mileage. So I would say you shouldn't need any shims. But always worth checking.

I just had mine done and the guys were shocked at how out of spec it was. Expensive to have done every year and will be looking into doing it myself.

Agree! If I may ask, what was the estimate that made you "crap?"

I'm not sure about the F3's but all other new 800's/675's are now 15'000 miles between major services. Personally I doubt they actually changed anything other than update the print in their 20 year old service schedule that they copied from the original F4

Bit of a coincidence that at the same time as they bring out a tourer they suddenly double the mileage between services


Mines due a valve clearance service in the spring, if it's too expensive I might just sell the bike instead?

Interested in anything that Sucks, Bangs and Blows!

Checked mine at 11500km, all within spec. You can remove the stator cover without dropping oil, if you are careful enough you won't need a new gasket.
