Jumbo's came with Betor forks and yokes 35mm on the earlier models and then 38mm on the later ones Ian

Nice one Ross ...... Lol how did you know i had run out !!!

Standard size 340mm , I had some 360mm on Jumbo 350 but bike looked too high at rear compared to 320 Jumbo (both work okay) Now running 350mm with hard springs on my Jumbo 350 , bike sits right and they work really well hope that helps

Made my own plastic backing , covered in yellow and then the black decals added .......

I have had a carb built by Eurocarb (Dellorto UK) for the Jumbo I had the same thing no such thing as the sx200 needle, I had to use a X2 needle, is that correct an X28 needle, if so I will get one ?

Cheers Ross, had an idea it was a sock, will try In Motion

Does anyone have any idea what they look like ? Or what to use instead ?

I got the tank from Woody, put it on my 320 , the sandblasting was a great idea, tank and badges are still in very good condition,

Motosing83 I have a tank just like that one ! like a dull rough finish and same badges? its not like my other two they are smooth.. ....

Looks Really good, thinking of the same rear shocks for mine :-)

Nice one , I know I have one side for sure, will have a look and send you an email , Jumbo ones crack all the time......

Like the silver frame on the 320 Jumbo!!

Some Jumbo ones would be nice??

Looks good Ross, you should go into production !

Like Woody says it has to be one of the most powerful air cooled trials bikes ever built The clutch can be a problem getting used to especially after using a modern clutch Mine is now standard timing, reed cage fitted, flywheel weight fitted and a brand new carb jetted for the reed cage Its amazing and makes me smile every time I ride it !
