well, the latest info is:
There are
NO kits for the later engines!!!
so, I am on the phone to Peter at D/UK to try to get help.....
otherwise, it looks like we will either:
have to run at a disadvantage to the other bikes
or
withdraw from the comp...
or
has anyone got an early engine?
mind you, having stripped this one down, and having got various work under way - replacing rockers etc, this is going to be a very expensive exercise!
