c90 airbox before I hurt my engine

trying sympathy vote now, must be desperate.
yeah on my 1974 6v c90, I have the actual airfilter and the base part that sits on the frame, looking for the rest....
cheers

I haven't got a spare but two things worth knowing...

1- It's the same part on all 6 volt 50 70 and 90s!! :o Hooray!!! (unusual something fitting all three!!)

2- It won't hurt your engine as it is - the filter is in place and sealing so the vacuum should be correct, it's just not as waterproof as Honda intended!

WOW something in common, I don't believe it :shock: Have I read somewhere these are hard to come by? but in light of Boo's second point, I guess you could fabricate something for a cover? it would be hidden after all. :)

thats good to know as im going to hunt one out for him and the sealing rubber.

but without that air box the engine wont like it at all, i know people say the c70 6v's are a bit grumpy with out the airbox, dont know if the 90 is the same but even if you take the sealing rubber from the top on my 70 i just wont run performance wise at all. ;)

it should work without the lid, but like i said before, i belive the 6v engines wont run correctly with out a complete air box, their were 6 volter air boxes in my parts, and the one sent you was the one with the largest diamiter intake on the inside, the smllaers ones are for the c70/c50. hope it all goes ok, i have boxes full of parts i minght post some of the parts up on the for sale pages. :)
