I did similar, You could remove the hose from pump to port, cap the pump outlets, and leave the pump in place and connected. No error messages then. Not quite as neat but does the job. ;)

Thanks! I did this and it worked. I don't like riding with the CEL on. I'll keep it this way until I get the cleaner looking kit from GTM.

What is the cost of this kit? And installation cost if i decide to bring the bike down.

How long before a similar kit is available for the new 850cc engine?

Based on the V85TT engine, a bigger bore cannot be (easily) done. 84mm is the largest piston size the engine cases and stud spacing allow. We shall see what they used on the new 1000cc water-cooled engine they leaked last month.

I know this has been asked a 1000 times, and the general answer is that it’s not worth the time or money, but after riding the bike last weekend I really want to know if there’s any decent gains to be had with some head work?

I already have Leo Vince pipes and a re-map which gives 53hp, so wondered if anyone has experience of trying to squeeze more power out with the new head design?

I’m of course waiting for a v85 engined roadster, bit in the meantime a bit more power would go down
nicely.

- Everyone I spoke to who had the 820BB KIT installed on their V7 were not unsatisfied. It is definitely worth it, if you want more power.
