Good Morning all!
I am forensically putting my 650B back together as I address every mechanical & electrical issue along the way. I say "forensically" b/c the bike was partially disassemble when I obtained it... parts in boxes and ultimately some missing.
I'm currently focusing on the air boxes.
The right air box is no doubt original to the bike. matches the diagram and fits.
The left side is a curiosity to me. It can't possibly be stock. Or, at least not for this model..
It fits perfectly fine, but it is completely different than the right side... meaning not a "mirror image" and it's made of plastic. The single biggest issue with it is that the crossover connection doesn't match that on the stock right side. So, I sourced a left side replacement that is on its way.
And this brings me to my question......
I'm sure these work whereas the engineers that designed them were pretty smart.
But as I'm studying them, I'm really curious as to how well they allow air flow?
Naturally, they're not air tight, but they certainly don't have any obvious air flow passages. In fact, the air boxes on my '68 - 72 Enduros are more ventilated.
Are these known for being a problem related to performance?
Am I going down the wrong path by even giving this thought?
Sure would like to hear some fact based opinions.
Thanks all.
