Ok. Through much reading and talking to Anthony about my '01 R6, I am going to get carbs cleaned and synced, trashing the K & N filter and going back with OEM. So this leaves me with my shortie exhaust and the sprocket/chain conversion (520 with a -1 +1) as the only upgrades. I want this bike to run at its absolute best. I am scared to death of messing with the carbs because I have noone else to back me up when shit goes bad so I am leaving it in the hands of a mechanic I have some trust in. I dont know jack about shimming a stock jet but will ask him about it.

Right now it appears to be running lean due to the crackling and popping of the exhaust during deceleration but I have not shot temps of each cylinder. I am getting some odd throtlle response when the bike is in the 6k-8k rpm range and based on what I have read that is indicative of running lean couple with the turbulence in the box due to the k and n filter.

Would a Dynojet stage 1 kit harm anything? From what I have read it may not help but I am looking for anything right now to get this bike running as good and as fast as can be. I would love to have the problem of keeping the front wheel on the ground but right now I dont think it is capable of pulling it off the ground. Dont get me wrong, it is fast and I am not experiencing any bogging problems but I dont think it is at its potential.

Let me know what you think and thank you for your time.

The shorty exhaust is an appearance thing, not a performance upgrade. It will leave you with a dip in the torque curve that no amount of jetting will overcome. That is more than likely the strange symptom you are experiencing at 6-8K RPM. A jet kit might help you, but it would work better with an actual performance exhaust. There is a reason the shorties are not used in racing...even many of the current R6's use a longer exhaust in World Supersport. And a jet kit is not just plug and play. jetting requires installing, putting the bike together, running it, doing WOT plug chop runs, checking plugs, tearing it apart, installing jets again (smaller or larger), repeating the process until you get the right plug readings at wide open throttle, then doing mid-range plug chop runs to get the needles set right.

Understood. I am looking to go with the delkevic 9" which should serve as a performance related exhaust. It will be connected to a midpipe and hung from rear of bike as opposed to the typical shortie install. Anthony (chief smoke dawg) runs this exhaust on his but not sure what tuning he has done in regards to the carbs. If you do not think the delkevic fits the bill of a performance related exhaust I am wide open to some budget friendly options. Whether it be a D and D, Yoshi, etc

I am definitely willing to pay for the process of jetting with the stage 1 if it will help the performance, responsiveness and torque of the bike. Again, just realling wanting to get this bike up to its potential.

Stay away from dyno jet. Save ur money and get a factory pro jet kit. I recommend the CRB-Y78-1.1-ti*kit
