4-2-1-2 exhaust

<< < (5/5)

MRieck:
Schule made a genuine 4/2/1 exhaust....I have one NIB. In general improved midrange without killing much top end. Most modern systems are 4/2/1...Akra, Arrow etc.
 As was mentioned....that Dunstall set up looks like it was more for convenience rather than performance.
Monty Campbell....quite a character from what I've read. Is he even walking the earth? ;D

Is the pictured bike shown yours?

If so where did you source the seat?

Thanks
