griffon restoration

[brokabolt]

Please could someone tell me where i can get head stock bearings for a 1969 griffon 250. Frame no.56B/423. It has banana forks. I bought the bike a couple of weeks ago and think it has lived in the states. The bike is almost complete. I also need right hand side panel,a/f inlet rubber. Should the exhaust have a resonator on the tail-pipe. It looks like someone in the past has removed it and welded a piece of pipe to it. I have stripped it down ready for powder coating and would also like to know what the original frame colour was. the air box and tank are blue and the nearside panel is metallic blue.
Many thanks. Mick

Hi Chris,

Looks to be another Nicholson spec Desert Griffon made it back over your way...56B would be banana front fork with a wide ratio gearbox and 3 gallon tank...more than likely with 19 inch front rim. Nick sold quite a few.

Hi Mick...Yes Stateside Desert Griffon. First came in the states without a silencer, as the laws changed we had to add a silencer. Most Griffon stinger mounts would break at the weld, or get bent inward from a fall. The 250 Griffon is very picky on silencers. We would have to use a spark arrestor to ride on state land and it would strangle the engine way too much.

You won't find an NOS rubber boot as most rotted...even new ones sitting on the shelves for many years would crack. If you do a search on "Griffon air boxes" I posted a pick of an rubber coupler that I use and works well. By chance does it have a Shell Motors decal on the steering head?

Post a pic if you can!

Good luck with your project!

griffon restoration

Hiya Kenny.
Not sure if it has 19 or 21 inch front wheel,havn't really looked as i was keen to strip it down to check the frame for cracks etc. The wheels are dunlop rims which are in exceptional condition(if original). It doesn't have a shell motors decal on the headstock. Why do you ask?.

Thanks John.
Remember them well with fond memories. We have a bearing supplier in lewes and hove. I will give them a try first.

griffon restoration/headstock bearing removal

Thought this might be of interest. Removing the headstock bearings is so simple. It took a mate and myself 15 mins max to remove both races. First remove the cage and rollers, the cages are quite flimsy and can be removed with a screwdriver. Then weld a washer just slightly smaller than the inner race on top of the inner race. We then welded a nut on to the washer which had the same thread as the slide hammer. Top yoke in vice(one man job), forks on ground, with me holding and mate doing the hammer(two man job). Job done.

Sounds a bit less destructive than drilling a couple of holes in the fork yokes so that you can punch them out. Provided you've got a welder and a slide hammer...

Hiya Kenny.

The rims should be high tensile. If they're chromed then they're not original.

Hiya colin
They're definitely chromed. 19 inch front,18 inch rear. What finish would high tensile rims have. Cheers.

Shell Motors in Southern California sold many Griffons. I saw a Desert Griffon on EBAY UK at one time with the Shell badge...thought maybe it was the same one.

Hi Colin.

Many USA spec Greeves Griffons came over here with chrome Dunlop and Jones rims ...might be because so many came over here with 19 inch front rims...I've never come across a 19 inch in high tensile...maybe Chris can help us on this one.

I wish more had came over here with the HT rims!

Painted silver...a very light rim that is light as an alloy rim...or very close to it.
