Interesting point
Me to on the 920.Interesting point
When I had new liners fitted to my Maney 920 barrels I got them silicon carbide impregnated by Laystall Engineering in Wolverhampton - after they'd been honed of course.
No Idea - it was a few years ago when I last used them.
That probably explains the gestures and comments from the French guy I had hone my Maney barrels!
Nikasil has been available on production bikes for more that 40 years.
I just saw an old add for them that says they are spun cast iron liners, which shouldn't be a problem. I think they must of been replaced or as Jim says been treated some how.
I bought them second hand although was told they were never used, they do look like new and unused, unfortunately I have no way of knowing what has been done to them.
Thanks for that. I was once wondering about using aluminium barrels with Nikasil. But the expansion rates would be different from iron barrels. If I race I always use methanol fuel. With the iron barrels, I usually let the barrels and pistons warm-up without giving the motor a rev. With Nikasil on aluminium barrels, the piston to bore clearances could be smaller. I am surprised how good methanol is in the 850 motor, it could have been made for it - even at low compression.
