Lucky for us in the UK, we are not tested for emissions on bikes.

I would post some pictures up but the site tells me I've reached my 2MB limit, cant work it out as I've deleted most of my pictures, some help would be great.

(A) I can host pics for you. Email them to me.

(B) When I installed Ivan's 750 kit in Malloc's, we ran into the same "too rich" issue and simply turning back the pilot set-screw a half turn pretty much cured it. Ditto on my 600 (again turning them back to 3-1/2 turns out instead of 4 seemingly took care of it).
I suspect that a lot of that has to do with the time of year Ivan designed the kits -- the fuel in the northeast USA was winter fuel at the time, which has MTBE (oxygenators) in it for pollution control and a higher-than-average amount of aeromatics (because they won't evaporate as readily in the winter)... But I'd have to slap both bikes on a proper exhaust analyzer to really know for sure if I tuned them perfectly, or left them running a bit rich (but they haven't fouled any plugs in 3-4k miles).

thats amazing - lowering the pilot & the needle. most bikes are tuned lean for emissions from the factory. your the first person thats posted lowering even farther the idle circuit.

I'm a very happy man, so is my KAT.

I was running with a K&N filter and a Carbon Can Co slip on, until I order a jet kit from Ivan, as apposed to the Dynojet kit and K&N jet kit. After doing a lot of reading and asking a lot of questions I decided to take it to the Pros to install, so off to HM Racing I went.

http://www.hmracing.co.uk/Default.asp?strTemplate=temPW3_001.asp&intPage=413&strLang=en&intLang=2&intLevel=3&intLevel2ID=387&intLevel3ID=&intLevel4ID=&intLevel5ID=&intLevel6ID=&intLevel7ID=&intLevel8ID=&intLevel9ID=&intLevel10ID=

When the above setup was dyno'd I was getting 84.0bhp Max power at 11500rpm, and the fuel mixture was very, very rich.

They then installed Ivan's jet kit to his specifications, so now it was set up with the stock filter and the needles where set on position #4.
This set up was still not correct as the fuel mixture was still very rich. They then decided to change the Pilot jet's to 107 as apposed to using 110.
They also changed the needle clip position to #3 then again to #2.

The new set up was much better with the fuel mixture almost perfect and #2 clip position on the needle, with the stock air filter.

When this was dyno’d I was getting 86.0bhp Max power at 11500rpm. I rode the bike home and could not get over how different it feels. It is so much more responsive and oh so smoooooooooooth, when idling the bike is quite and smooth, On the twisties the power is more responsive and there when you need it. All in all I’m very happy with my bike. :mrgreen:
