deja vu !

[ade the blade]

It's a real puzzler!?!

Just thinking logically, it's lack of fuel or too much air. As you've studied those carbs in HUGE detail it's just got to be a leak somewhere along the air intake system. God knows where but perhaps there's a crack or god knows what at some point from filter to inlet?

You know that the bike runs fine with a K&N so it's not that. I just feel that you're clearly quite knowledgeable (way so more than me) so the obvious things have already been checked. That leaves the unusual and not so obvious things left I guess?

quite right my mate..............probably linked in some way to the slightly warped front rotors :rollin :rollin :rollin
