Cr750 rickman 1977

[Rickman Pete]

Afternoon all,

Ive recently obtained the above rickman based on a cb750.

It has been dormant for a lot of years and im just trying to do some home work before things get replaced etc.

It has a z650 front end and brakes on it. I was told this was because they were a better upgrade. Anyone else have any info o  this please.  Ive got to replace or refurb the fork tubes and one caliper as beyond repair but just wanted to make sure i was going in right direction before i start

Thanks

Pete

Welcome to the forum Pete.

We're going to need pictures of the bike to judge it 

A few of them on here so some first hand advice should be along to discuss your questions.

Perception from me would be that the 650 brakes if twin disc may hold an advantage,  thought forks are same size stanchions for both so not much in it from technical sense.

Hope you enjoy getting it going and riding it.

[Rickman Pete]

Thank you.  Yes it got twin discs so that makes sense. Ill get some pics up

Welcome to the forum Pete - keep us upto date as the project progress'

Welcome to the forum Pete.
I have a CR750 (in bits!). Mine has the original Rickman forks and I think these are of a lager diameter compared to the Kawasaki items. I have twin cast iron brakes with AP Lockhead racing calipers mounted on cast Ronal wheels. Rear wheel has a single disc with Lockhead racing caliper.
Brakes wise it would easily out brake a mate's CB750F2 with Honda twin discs.
My bike was the one built directly after the S&S CR750 as tested by MCN back in the day. It was built by S&S and still has the ear splitting 4-1 exhaust fitted but at some stage the
836cc engine has been swapped out with a standard engine. The turning circle is diabolical in London traffic so don't even think about using it for Deliveroo food orders😏!
Spares are limited for these frames although I'm sure you can still get the eccentric swing arm spindle adjusters (I've lost mine!).
Please post some pictures, it will give me some inspiration to collect mine from the garage in Glasgow and bring it home to restore it!

Hi laverda

It won't let me post any pics for some off reason.  Let me have a look when im at work on my pc as on phone at moment see if that sorts it.  Yours sounds a nice little project. What year is it. Mines 77

Pictures, you may not have permission yet being a new member.

Many forum do it to vet out the wrongly intentioned,  administration will ultimately let you know or facilitate if you pass muster I think.

Here you go Pete, it's not a good photo and was taken some years ago in Glasgow when the strip down began. The head gasket was blowing and it was pumping oil out through the breather. This has become one of those 'unfinished projects' that you see advertised although this is due to Glasgow being 400 miles from my home (it's a long story!). I'm hoping to get it back next spring when I have some room in the garage and I sell my restored 400/4 with 0 miles on it since the restoration (another long story!!!).
Anyway, the CR750 is a 77.

Cant see a photo dave.

You made me think when you mentioned adjuster.  Mines hasnt got any, in fact my swing arm has no allowance for them. It must be tensioned some other way?  I've got a few old photos of it back in the 80s 90s ill check to see what it ran

[Rickman Pete]

Can see it now.  Nice bike dave

I have a set of swing arm adjusts i assume they alter arms to take slack up from chain?

[Laverda Dave]

The swing arm adjustment isn't in the conventional way i. e. at the end of the swing arm at the rear wheel. It is adjusted at the swing arm pivot at the frame using eccentric adjuster discs. These are inserted into a housing in the frame and being eccentric they adjust the swing arm backwards or forwards. When the eccentric adjuster disc no longer provides the adjustment required you swap them out for another one with a more eccentric profile. I think there are five sizes of adjuster discs but I may be wrong, I lost mine years ago!

You can post pictures when you have more than 5 posts Pete.

Which you now have. 

Post away.
