Charles, This is a classic .... "two normal looking plugs and two that are darker" ... and please correct me if I am wrong but the darker ones should be the ones in the rear ...... Been there ... done that ... got a tee shirt ......... and if you keep putting bigger and bigger main jets in the rears will just keep getting darker and the fronts will continue to look just fine. The "I don't want to run" behavior should be until you get past 4500 RPM .. at which time you need to have your insurance paid up because you go into warp drive ......... On the other hand if you get into WOT early you can usually leap past the 4500 RPM flat spot, (which only happens if you sneak up on it like a normal person .... ie: less than full throttle). If you find this to be the case ... you should at least re-oil the front "oiled at the factory" filters ... or put socks on them, (UNI socks) .... These are exactly the symptoms you would have with un-oiled filters or with no restrictors in the main air jets. There is just not enough vacuum to suck the fuel out ... you can go all the way up to the DJ190s and the fronts will continue to look fine ... the rears will get darker and darker. The reason the rears are behaving normally is because there is more intake resistance back there ... since they are backed up against the frame etc ....... The fronts are too open and without more oil or a sock there isn't enough vacuum at lower RPM to get sufficient fuel. Also ... keep the fuel bowl vents mounted high in the air cover ... as this will help equalize the pressure in the fuel bowls ... cutting them off or doing something clever with them will have an adverse affect on the fuel trying to get up the jet tubes ...... I am surprised Dynojet didn't already have you duct tape the front filter already so they could lecture you about filter oil ........ IMHO of course ... (but you can have my tee shirt if you want). campbell ----- Original Message ----- From: <[EMAIL PROTECTED]> Subject: Two Bros Racing oval slip-ons & Stage 7 Kit cont. As I said, After trying with the needles in the last position (sixth from top), having the most amount of fuel and the bike behaving like a mad cow, I tried the 5 th notch, which was the recommended position from Dynojet after listening to my situation. Now the bike performs well, has regained its lost punch, but there is still a flat spot once warmed or better still, the engine behaves as if it was running on three cylinders. As you accelerate the sound continues to be more like a twin/triple and then it suddenly picks up revs after some hesitation and fire and power brakes loose making the bike run perfectly well. checking the plugs I find two perfectly normal clear brown and two slightly darker coloured plugs.
