No, if it's failed on HC's it must be running very poorly generally, it should pass easily., albeit possibly only when rpm is raised a little

You need to check all usual culprits, ignition, carbs etc, but I would start with valve clearances, they closed up on both of my ZX10's & made them run like a bag of poo

Furore Formula Car - the only two seater modern Formula Car lookalike. I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator headlights, indicators, mirrors etc, best prices in the UK! Take a look at or find more parts on Ebay, user names furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

I think balance can upset HC too.
If you can get hold of a balancer that connects to all 4 at the same time it makes life very easy. Remember to balanceat idle and just off idle to make sure the linkages are set correctly.
