A7 / A10 Head question.
« on: 09.04. 2010 11:09 »
Gentleman and Orabanda,

Have a new set of stainless exhausts on my A10 Plunger ( from Armours ).

The RH header pipe "L" bracket appears to be about an inch too short to fit flush against the engine / frame on the centre bolt, as a short term fix a small U shaped piece of metal fills the gap.

Question, could someone who has both an A7 and A10 measure the distance between the exhaust ports to see if there is a difference.

I am thinking I was sent an A7 RH header if there is a difference ?.

Am having a welder insert and 25 odd mm piece in the "L" bracket to fix the problem

The distance on both my bikes is the same, but have to add that both are s'arm frames. Don't know if there's a difference to the plunger models.
The only difference is the distance between the straight portion that goes into the head and the L-bracket which is a bit shorter on the A7 (shorter cylinder barrels).

Cheers, Markus
