I did one 15 years ago into a Suzuki LT250R with a single carb and a A Graham Bell / Dennis Foran 2 into 1 pipe,
Brilliant, made the mistake of selling to a friend and it was stolen, never to be seen again,
Pretty hard to beat a powerful, multi cylinder 2 stroke on the pipe,
All Flattrack Fans will love these bikes,
I have had the pleasure of seeing them and the big brother TZ750 in action,
Unbelievable is an understatement,
PS Firko you should see the pipes of that bike you posted,
mine will be similar to the Tom Horton #55 bike
