Kits like cobra or sigmajet are great for tweaking, judge your present performance first and determine if you're in the ballpark; Is it responsive throughout the powerband? How's your exhaust looking? If the pipes are showing signs of getting too hot (chrome bluing, exhaust tips chalky white=too lean, tips black=rich).
On to the spark plugs. "Reading" a plug gives an excellent picture; after a somewhat aggressive run with out too much idling pull the plug and have a look at the porclean insulator just above the electrode gap. Best is a nice even cocoa brown. Black=rich, white=lean. I would suggest zeroing in thoroughly, then consider going above and beyond if you wish.

I have a 2002 Honda sabre1100 11239 miles and been rejetted with cobra pipes, this is my first cruiser.I have been riding crotchrockets the last 15 years, need more torque, what should I do


Are you comfortable with your jetting? Is it performing well through the powerband, and does it appear to be zero'd in? (reading spark plugs, exhaust pipes not getting too hot etc). Is everything else up to snuff like timing? DYNATEK performance makes a nifty performance ignition that can wake up your bike, and a free flowing air intake can help it breath easier, you've taken steps to get it "out" better, be sure it can get it "in" better and burn it most efficient.

Have a 04 Yamaha V Star 1100 Classic, want to install Cobra Slip On Drag Pipe exhaust, is it necessary to have bike jetted?


It is not essential but the static timing may need to be advanced slightly to compensate for the different back pressure.

Check valve clearance, as vlaves wear the gap closes, most riders don't bother to adjust them till they have a problem like this.... By the way the valve may be part of the issue for backfiring while deccerating but Pipes cause this.

HI if this is a bike with carbs then I would highly suggest rejetting them with the after market pipes, if it has injectors then I would recomend checking to see if a power commander is availible for the bike so that you can tune the fuel curve, it will help with the performance as well as your fuel problem
