Hi all - doing a little advance planning for my someday 1956 Dominator 99. The cylinders have several large pieces of finning broken off and missing. I missed a set on eBay that came up here in the USA. Aside from the missing boss for the dynamo strap , does anyone know if the the new 600/650 cylinders listed on Norvil’s site will work with my crankcases / cylinder head ?
Thanks for any help - Richard

If anyone has bought new…
If anyone has bought new cylinders and had a few thousand miles of trouble free use , it would be helpful to post. I am very lucky, my std but worn cylinders cleaned up at 10 thou and I managed to find some pukka 650 pistons. I'm happy to accept a bit of cold slap and have an air filter fitted,I also use a touch of 2 stroke in the fuel to protect at cold starts. With luck the motor will see me out. Funnily it was me that instigated the initial idea production of these cylinders, but there were problems with businesses going bust and Norville picked up the pieces. I do hope they work ,time will tell.

99 barrels Queries
hello, now hears is a tip I would wait until the right set of barrels come up for sale as these have the thick cast mounting on the right side front push rod tunnel for the dynamo stud mounting, and the later one do not have this and you have a real job of fitting one the 650 are a different barrel that's why they have a different parts number as these barrels are set back just about 3/10th, and if you doing your digging around you find a good set of barrels and BHB pistons as well these are standard items, for the 1956 model 99 these parts are out there is finding them that's the fun part so good luck and happy new year I had 56 years good with Norton twins yours anna j

I thought Andover were planning to make Dommi barrels but because of the drawing issue they probably won't now, such a shame, disgrace really. How can Norvil be advertising barrels to factory drawings when the club is 10's of thousands of pounds into litigation with ANIL over the factory drawings issue? What a mess, allegedly. Hopefully not breaking the new posting rules here

I think its a gamble. In theory it should work. It all depends on the quality of the product and Norville's ability to provide QA to the finished article .Will they accept a return and pay for the shipping of a used item that turns out to be unacceptable" IN YOUR OPINION" ?. Not convinced of that. So its back to a gamble, do you feel lucky yank?.
