Mintor 1.70

[Henderson,Eric]

I mean the one that I bought with the engine that I call a "Bolly" but should probably start calling a Mintor pipe?

Never seen a partial baffle before. I guess I should just stick it on and see what happens :-)

Eric,
Do you mean a real Bolly, or the Mintor CF pipe.  The Mintor pipe has a
partial baffle at 11.25 and the real plate at 13-5/8

I am a bit confused on the pipe lengths that are being used. I measured my
ES (OS-clone pipe) and the baffle is 13.5 inches from the inlet. The Bolly
pipe that came with my Mintor has the first baffle at 11.25 inches.

With the ES pipe I am at 24.24" from center of head with low rise pipe. What
I was going to do was use the Bolly but elected to use the ES because it had
an integral stinger/diverter.

If I now fit the Bolly I am thinking that I am going to be way-off in pipe
length, Any experience out there with the Bolly and this header on a 1.70
Mintor?

Regards,

Eric.
