I don't know if there is any difference between the Aero (RRG/RRH) and the RRJ/RRK version?

Re: CBR400 NC23 Aero Valve cover gasket
Gimly..the gasket would be almost impossible to make from scratch, as it is a moulding, not a paper gasket.Shouldnt you know that if giving advice?

Try this
http://www.ebay.co.uk/itm/HONDA-CBR400R ... 2c8c4664f5
I know it's thew whole top end set but I hope it helps
Sorry
The link says not available but as I post I have a paypal page for £119 to complete purchase
It may be relisted but the ebay page did say 2 available & genuine Honda
So after all that, this post is rather redundant
One last option ???
I entered the item number ( 191331984629 ) in the search box & the listing came up as 2 available !!! ?

Re: CBR400 NC23 Aero Valve cover gasket
Well after all that, I've bought a set, as they appear to be rocking horse sh*t
I did see a NOS one on ebay a week or two back from a private seller & they wanted £45 for the rocker gasket !!
So, as I've heard that a genuine head gasket is £50+ I suppose £119 inc P&P from Japan aint too bad
Bearing in mind that the bikes are 20+ years old, any spares/consumables are likely to be scarce
Good luck & happy hunting
