Laverda Dave:
Thanks for all your advice Michael and especially about the tires, I'll have to get some new ones as they are rock hard!
Pistonbroke, no I didn't make it but bought it about 20 years ago. It has a SWL of 350kg and easily lifts the Jota without bowing. I have added a photo of the manufacturer details although I don't know if they are still going?
I've made some progress today and for the first time ever I struggled to get the carbs free, if it wasn't my bike I would have bet they had been glued into the mounting rubbers!
The state of the carbs inside the bowls was something else!
I have cleaned the first of them in the Ultrasonic bath using a carb clean chemical and so far I've had to give the carb two treatments.
I need to order the carb o-rings although I've read on here the cruzinimage rubbers are not good, does anyone know of any other suppliers, I need all the rubbers including the ones on the fuel line T-pieces and the link tubes between the carbs. I don't really want the full jet kits as hoping to clean the jets I have as they were replaced with genuine parts when I restored the bike erm....27years ago, its only done 6000 miles since then😳.
I took a photo of the sticker on the rear mudguard when I entered the bike in the VJMC AGM show, it didn't win but got a mention in dispatches!

Nurse Julie:
Contact Gerben about the O ring kits...he does them for all the other SOHC/4 carbs so I'm sure he will be able to help.

Thanks mate, I’ll have a look for that

Hiya, meant to say that while you've gone to all the hassle of removing the carbs, (full set of knuckles and clean vocabulary?), the items which gave me the most problems were those tiny little spindles that the floats pivot on. What with modern fuels and having stood so long, mine were all gunged up meaning that the floats were sticking. Remove them and give them a good polish. While you have them out, it is well worth replacing the jets which will have suffered the same fate. Hopefully then, you can fit and forget!! One of the modifications which I purchased, but haven't used yet until the carbs have to come off, is a set of small allen headed bolts for the float bowls, which means they can be removed/replaced without too much heartache. I have a good memory, but it's very short, which means I cannot remember where I bought them, every chance it was someone on Flea-Bay. Regards, Michael.

Laverda Dave:
Thanks Julie, I'll drop Gerben a mail later. Hopefully he will also have some JIS screws for the  choke butterflies as 4 of mine were chewed up (memories came flooding back when I rebuilt it last time and the problems getting them back in).
Michael, lucky for me all the spindles are OK on the floats 👍.
