If I can pick some brains...
How much of the power improvement from the exhaust is due to the chambers, and how much due to the cans?
I have a set of race cans I wanna put on, but standard chambers still. Just wondering what I can expect..
MC 21R with PoshFirm derestrictor
I have
K&N Pod filters, Race cans,HRC jet kit to add...
(plus the SP forks Off ebay last night!)
Also.. Pre-mix or not? my oil pump has the 'leak into the gearbox', and what with the jet kit I'm wondering if it's worth changing..
cheers for any help
