After 25 years of ownership I decided to tackle the dreaded valve adjustment on my CBX...



It's actually not as hard as it looks!

Good to hear, Trevor. I recently did my "new" Guzzi. Talk about easy.

Doing the valves on a Guzzi is like doin' them on a old Chevy 'blue-flame' 6, it's got pushrods! Trev, I rode an early Honda CBX back in the day, for a while, it was a bit errr... smoother, than my old race H2!!

Easier than the Chevy... you can pull up a chair to sit on, and the parts are right there in front of you. The only easier bike to adjust valves on is a 2-stroke.

I still don't have the courage to do the valves on my '85 Ducati Mille MHR bevel twin...
Who knows, somewhere in the future I maybe forced to do it, as the specialists, one by one are more or less fading away these days...

the bad thing is hoping the valve cover gasket dosnt leak (OEM is your friend)

After 25 years I bet the valves were tight should see an improvement.

That is exactly the reason I'm doing it myself!



I bought a new (OEM) gasket & it's held in place with Threebond.

I also bought Mike Nixon's "Adjusting the CBX Valves" booklet, a quality set of feeler gauges, a good digital caliper, a MotionPro valve bucket tool and a nice set of tweezers. I'm now waiting on six shims to arrive. The guy who supplied the gasket & MotionPro tool is a CBX specialist & he stocks 1/2 size shims, for those of us who are anal!



Sounds like doing the valves on my Morini 3 1/2 Sport. Dead easy. If you ever come to Melbourne, Australia, you'll have to come along to a Classic Italian Motorcycle Association of Australia coffee get-together. Some very tasty classic Italian bikes come along. I also talked a Guzzi Le Mans owner into biting the bullet & buying an H2C (he rode a 750 triple "back in the day").



I was getting the valves checked/adjusted in all that time! However, the only guy I trusted to do a proper job retired a few years ago. I delayed the job as I hardly ride the bike. Only one valve was out-of-spec (.04). Five others are within the acceptable range, but I want to go a smidgen looser with them.

Trevor, is that an early or late CBX, (colour?), and what have you got for an exhaust system? Spent a bit of time on a silver 1st model, when they first came out!!

That's another reason to visit your country then, thanks.
