1981 CB900FB2 Bol Dor

[Otis]

There is a a 1981 CB900 FB 2 Bol D'or for sale on ebay for £6995.00 and it looks mint but does seem a tad expensive.

It is a bike I think I would love to own having had a CB750FB from new in 1981 (Paid £1762.00) and drove it out the showroom. I am just putting my toe in the water at the moment but would appreciate any thoughts/advice/guidance as to whether this would be a wise purchase.

Thank you in anticipation of any replies.

Sounds a bit expensive to me and from a workshop point of view they are expensive on time, also need to be run very regularly as if stood the carbs get clogged

[Rozabikes Tim]

Ditto pricey...

One of my favourite bikes, I would like to find a decent cb900fc though, no fairing version, gold reverse comstars. However that one is way overpriced imo.

Coming up for sale today with H & H cb750 Bol dor. Not exactly what your looking for some interesting bikes, might just have to watch a bit of the auction.😜

One thing I would say, having had a CB900 for a while, is that they are big, heavy bikes - and mine didn't have the fairing which gives additional weight and bulk. It was lovely once it was moving, but very heavy to move around. I sold mine because of that - just mentioning as we are all getting older, and might not find old bikes as light as we used to.

Didn't the CB900 have issues with the cam chain tensioner? I thought they have two cam chains, one from the crank to the inlet cam and another from the inlet to the exhaust cam?
A mate had one when they first came out, a silver and blue one. He really wanted the CBX (didn't we all!) but they were massively expensive. Really comfy seat from what I remember going on the back of it a few times.

They did have the 2 cam chains you describe Dave. However I can’t ever remember a problem with them and it being one of my favs I’d always select it if one appeared for a service in the morning. I’ve done hundreds of services on them but not done any engine work at all on one. Never saw one apart at all in fact, which considering the volume of bikes QPM sold is surprising and must reflect them being a decent engine.
The only problem I can think of was one with the spark advancers being interfered with by the generator’s electrical pulse and even that was rare and only on the FZ model. Took me some time to figure that misfire out.
I also suspect they had soft valve seats as it wasn’t uncommon to change all the shims at the first service. Either Honda got their sums wrong at the factory or there was some wear occurring during the first few hundred miles. They were fine after you changed them all though.

The first 750 twin cam had a mod to reduce oil pressure at sprocket seal as they blew the seal physicalu out of the cases and to replace was engine out, and i remember doing the shims which was a rear pain with the Honda tool and took forever

A bit futher off the strict Bol D'or topic. Just seen this on Ebay. 1100 - real mans version. 🙃🙃

Doesn’t the word “project” fill you with fear?

I had a 900FZ in about 2009.

It was gorgeous and what I really wanted when I was at Uni.



I lent it to Classic MCM for a road test and the loved it. But they broke the tail fairing when pushing it up the ramp into their van. Amateurs.
