I have not herd of anyone needing to shim the exhausts, the intakes are adjusted with w screw/lock nut. (I haven't herd of any intakes that REALLY need adjusting either).

Talking to my honda dealer the other day about this, I asked when to have them checked,they replied 30,000miles is ok but we havent had to make many adjustments on the vast majority of bikes we have inspected....

It is the other way round, the intake ones are adjusted by changing shims (and nobody has ever needed any yet) and the exhaust ones are adjusted with screw/lock nut.

Iíve started to strip down my bike for its first valve check. Never have I had a bike that so much kit has to be removed for a service, itís virtually giving me nightmares !!!! Awkward just doesnít accurately describe this job.

Getting close to 60k on my 2016 manual, to check or not check the valves. The bike runs perfect, starts perfect, gas mileage the same as the day I bought it. Iím thinking,just going to keep on riding & maybe check at 100k. 💯👀😎

I have stripped down my VFR VTEC in the past to get to the valves - and this is considered a complex bike due to the V4 arrangement - but I can confirm that the CRF is even more complex to get to them. In my case, I decided to leave the dismantling/assembly job to a mechanic/friend with the agreement that I would check the valves, which I did.

I haven't found much wrong with mine at 46K km, apart from an exhaust one that was slightly open at 0.27 with limit 0.25. But maybe 100K km is too long an interval for the exhaust ones that use screw/locknut - just in case any one of them closes too much (the intake ones that are shim-based will be surely within the limits).

Follow the procedure in the book.
yes there's a bit of stuff to take off. Clean as you go.
Exhaust is screw and nut. My exhausts were on tight side, but in spec, so I moved it to the loose side, super easy adjustment.
My intakes were down middle of spec at 27k km.


For those on the fence, roll the dice. I may skip my next one, as I know where I'm at after break in. But it's there a reason for the interval check.
The spark plugs are due at 48k..so I'll scratch the above comment, and go in and check the valves anyways. The two inner spark plugs are impossible to get to with the tray in the way.
