Material: Billet Aluminum ------------------------------------------------------------------------- FAQ's Q: What is the overall length if these velocity stacks? I have a modified bike and not a ton of clearance in that area. A: hi! they are 1.75" in length. As a general rule of thumb for jetting for velocity stacks, most people bump the main jets up 1 to 2 sizes above the stock jetting. In some cases,(on some bikes), if the bike has stock mufflers, we can get away with just an idle mixture adjustment and a good carb synch. You would probably go up more sizes for straight/open pipes. But the issue is that individual bikes are just too different to offer blanket advice for. The types of muffler (or lack of a muffler), and header setup, your altitude, different cam shafts, big bore kits, state of engine wear and tune,... they're all factors that change jetting specs. So, the simplest thing to do is start out 1 to 2 sizes above stock, and experiment from there. It is also recommended to check out the bike forums related to your model, to see what other guys with similar bikes & setups are running theirs at. Dynojet and Carbjetkits are well known jet kit suppliers. jetkit.com/ or dynojet dot com or carbjetkits dot com also try: carbjetkits.com/ at jetkit dot com also try carbjetkits dot com note: you will not see any performance increase unless you rejet- because the only thing that has changed is you are now flowing a lot more air, and that can actually reduce performance, because your fuel/air mixture is off. You need more gas in the mix to compensate for the higher airflow. If you have a 600 or 750, these are small engines, and therefore only small gains can be expected, you would probably need to also install a competition, hi-flow/ low restriction exhaust, and correct jetting to feel a noticeable change in all around performance. You should feel a slight difference in high rpm performance with just the stack and rejetting. A good header and exhaust muffler, velocity stack, and dyno tuning-rejetting, will unlock full benefits. ------------------------------------------------------------------ ACTUAL EBAY FEEDBACK: Item as described, well packed, resonable shipping, Thanx !
