Hiya,

Couple of questions

1. Is this lot still for sale?

2. Can you explain what parts i'd need to swap this lot into a stock c90? Ie would I need the crank on top of the piston + barrel?. So is it £150 for all the below or £375?

If you still have the 6volt big bore kit I may be interested.
Can you give me some info on it please, such as what the new capacity would be, if the compression ratio is raised and if the standard oil pump would be up to the job in your opinion?
Regards,
Brian
