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. |

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... |

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

Quote: the specialists, one by one are more or less fading away these days... That is exactly the reason I'm doing it myself! Quote: the bad thing is hoping the valve cover gasket doesn't leak (OEM is your friend) 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! Quote: I recently did my "new" Guzzi. Talk about easy. 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"). Quote: After 25 years I bet the valves were tight should see an improvement. 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 |

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.
