Bitza hey mate yep definitely around although currently in Kampala with S**T internet access

The secret for you will be keeping the gas speed as hight as possible out of the heads.

All the power on a 2v is made in the head, it is a rubbish design made to work with the legendary valve train
Until you spend huge wads of cash on some very seriously modified heads don't go bigger than 45mm on the primary tubes in fact 43mm would be better but that will involve a custom made header get a decent 45mm system and have it ceramic coated, this will reduce heat loss by around 20% will keep gas speed up and you can pretty much do what you like with the end cans
