G'day Darren,
The 376 will not fit with the filter, I cut the filter housing off the mounting ( i.e. I have no air filter ), screwed a bellmouth onto the 376, will post photos later.
I have the unit in the photos above as a spare that I will install on my bike when I find a well priced type 6 and A10 rubber boot to replace.
