I liked the added power this Leo Vince pipe gave my PK, but not the noise so much, I prefer under the radar in the neighborhood.
The noise will be fine w/ this one, let 'em know I'm coming.
This pipe is considerably different than and much better than the proper bolt on Leo Vince pipe that's on my Primavera(it's like a Polini copy).
The PK muff mounts different - from behind and lower, off a bolt that runs through well under the main mounting bolt centerline.
I welded on an extension after flattening part of the original mount to get needed clearance.
Still comes off easy enough, undo bolt & spring, pivot and pull.
I had to bash the frame lip back a little bit
and grind the pivot a touch.
This is the long stroke 4 speed motor I was hoping to get installed & did after heavy cleaning and new rings + hone(complete stator rewire too). Pipe works nice, keeps pulling strong for longer than before. Highest temp after long uphill was 405 F and plug looked fine. Maybe a 133 kit in the Spring.
I hope OCThud is noticing that I retained the old prebent kickstart lever from the original motor, thus hopefully avoiding lever getting slammed into a big rock.
