Yes it will have its maiden voyage on Sunday, and I have decided to keep the standard mufflers so it original. The bike has had a short test ride yesterday, I am very impressed how light it feels and the response form the torquey motor is mind blowing. Just finished going over everthing and it should be good for the practice, as long as the starting system I use works.
There is no way the DR 400, DR 500 or the XL 500 bikes I have raced or built can compare although that TT 500 in the maico frame of Brownies was very fast and Graeme's old Profab HL was very torquey.
