Hi folks, I am new here, I ride a C90T but I know my wife would never get on here and ask questions pertaining to her bike. That is a 2002 LS650P. I took the trash can off the side of it and put a Dyna muffler on it. It is an OEM muffler baffle in tact. My mechanic at the shop where I bought my Boulevard told me that it does not need to be re-jetted because it is a baffled muffler.The bike starts, runs and idles great but has an ever so slight flat spot at the beginning of the throttle after you shift. He told me to open the idle mixture screw a full turn or I could turn it in till it seats and then back it out 2 1/2 turns. I think I have exceeded that by at least another 1/2 turn. It is better but I am not sure it is cured. My wife is new to riding so it's not like it has to scream. That would undoubtedly just make her afraid of it. However, I do want the thing to go when she needs it to. I am just curious about the whole rejet thing. Some same you have to and many say it is not really needed unless you make fairly radical changes to your bike, like an open muffler or performance air filter, etc... Any feedback would be greatly appreciated. Thanks in advance and ride safe, tuneman

Make sure youve got the slack outta the throttle cable, so youre actually opening the carb & not just turning the handle. When I did that, it really changed how it came out of a corner.

If youre out much past 3 turns, there may not be enough spring pressure to keep it from movong. check & see how it feels, watch it, mark it with white out or a marker & mark the carb for reference spot, if its moving, solve that.
