Question Griffon 380....or 360....or QUB

Hi all,

A few pics of my griffon twin port in first stages of restoration. Its my first Greeves so hope I can do it justice, but looking at some of the superb examples you guys have produced, I'm feeling a bit intimidated. I'm not looking for a concourse restoration, just to get it up and running and entered in the pre 65 scrambles. Engine is with Steve at Villiers for some tlc as the machine has been stored for at least 17years. It appears to be a real bitsa, with 360cc barrel and a qub head. Anyone tried this combination? I'm thinking if this is a workable configuration, the reduced power could produce a more tractable machine for a rooky like me.

All fibreglass bits are there and a little filler and paint should see them good enough. Fuel cap has polished up lovely so the project is 99% done Forks are totally shot and non standard so have to go, but luckily I have a pair of Ceriani's lined up from a kind forum member.

Not sure about the carb pretty sure it is also non standard. Any thoughts if it is worth perservering with?

Both inner and outer primary chaincase show signs of damage. I'm told these are hard to come by so if anyone out there can help...

Just waiting on return of the engine, and an opportunity to pick up spares. I was going to rock up at Marks Tey on 26th March, pick up the parts on the way, and see how you guys get on. Can't wait....

Hi Soggy,

Project looking good.
Can you check that the tank is not original as modern petrol will eat its way through and clog the carb etc.
Roger Inness does a really good modern replacement that stands up to modern fuels but there is a bit of a waiting list.
Hopefully see you at the races.

Hi Craig, any giveaway to tell if tank is original? I think I saw advice on forum saying if tank is emptied after every use and not left with fuel standing in it, then it doesn't seem to cause problems. thanks for response though, I was going to pick up paint and lacquer today, so you may have saved me a bit of cash and time...

Hi Paul,
You can also use petrol that does not contain ethanol which will help also but safest way is new tank I think.

Don't know the best way to tell but if you contact Roger he should be able to help.
He is a good guy and very helpful. I don't want to give number out here but if you PM me I will reply with number.

By the way I think the primary case looks much better than any I use and I would give the carb a try and see what happens. White spark plug tip is the warning to look out for. (Kim, jump in with some good advice please)

Bottom line is build it up and hit her a kick and see what happens. If it runs then bring to the race and enjoy.

The carb is a Mk2 Amal, better than the original Mk1.

Thanks for comments Craig & Johnu. I'll certainly try the carb in that case. Just out of interest, was the mk2 fitted to later models or was it never used on the Griffon?

Default steering head bearings

Hi all,

Anyone know what size taper roller bearings I need for the griffon. I've picked up the ceriani forks and yolks to replace the none standard ones that came with the bike, so size should be to original factory spec. I've seen elsewhere on the forum good things said about Timkens from QualitybearingsOnline, so if anyone can help with internal and external dimensions, it's just one click and job done.

On the subject of forks, anyone have a preference / good experience of hard chroming companies?

In other news, gearbox just dispatched to Geoff Nunn for some tlc. Kim, when the box returns I'll let you know how many gears should be in there.

Hi Soggy,
Check out my QUB Mk2 post. I used a company for the front forks that where quick and very good

Acknowledged experts for chroming forks are Philpots in Luton (www.pittedforks.co.uk). There may be others nearer, for example Precision hard Chrome in Doncaster, 01302 330050.
