#450277 roadie56 (User) Fresh Boarder Posts: 43 HP gains?? 2000 1600 4 Months, 2 Weeks ago   What is the stock HP/fpt of a 1600 and what can I expect with adding doul cobra pipes with a k/n air kit?-Just added the new parts and want to know how much to expect-I can not ride til spring-got a bunch of snow last night-can't wait to try it out thanks   Logged     The administrator has disabled public write access. #450279 Questcap (User) Platinum Boarder Posts: 3209 Re:HP gains?? 2000 1600 4 Months, 2 Weeks ago   Stock HP is right around 62. With Stage 1 type mods, it's possible to increase HP by as much as 20%, or to 74. Just by adding pipes, and an air kit, you're not going to get 20%... and by adding those 2 you'll have to rejet the carb, or you'll likely experience worse performance.   Logged     Sig pic deleted - larger than 450 pixels and 50 kb   The administrator has disabled public write access. #450280 Questcap (User) Platinum Boarder Posts: 3209 Re:HP gains?? 2000 1600 4 Months, 2 Weeks ago   To experience a full 20% increase, you need to rejet the carb, bolt on a ported manifold, probably use a 2 into 1 exhaust, and install a Dyna 3000 ignition unit, as well as some kind of Big Air Kit. (A universal K&N bolt-on filter can accomplish the same.) I've done all of those on both of my R*s. It's certainly given me the expected gains on one of them, but the other needs some more tweaking to dial it in and get it right.   Logged     Sig pic deleted - larger than 450 pixels and 50 kb   The administrator has disabled public write access. #450281 nightstar57 (User) ride it like ya paid for it .. Platinum Boarder Posts: 2937 Re:HP gains?? 2000 1600 4 Months, 2 Weeks ago   and while you consider rejetting,port the intake first..with the pipes,porting,jetting and filter you should be hauling pretty good !!!   Logged     The administrator has disabled public write access. #450296 Erbman02 (User) Platinum Boarder Posts: 3801 Re:HP gains?? 2000 1600 4 Months, 2 Weeks ago   stock hp on a 1600 is 52hp 88 TQ approx. on a 1700 62hp 94 tq approx. on a 1600 stage 2... pipes, air kit, ported manifold, properly jetted carb, Dyna3k, should get somewhere between 15 to 20% increase in HP and about 5 to 8% increase in Tq. anything more than that will require engine work. if you go here, they have dyna charts for the 1600 & 1700, looking at the graphs you can see where they are at stock and with the mods http://www.starmotorcycles.com/star/accessories/acscgroupdetail/5/18/91/2330/all/1/7/groupdetail.aspx   Logged     Last Edit: 2012/01/12 12:59 By Erbman02.     The administrator has disabled public write access. #450400 Questcap (User) Platinum Boarder Posts: 3209 Re:HP gains?? 2000 1600 4 Months, 2 Weeks ago   Thanks for correcting me, Erb... at my age, it's getting harder to remember things straight anymore.   Logged     Sig pic deleted - larger than 450 pixels and 50 kb   The administrator has disabled public write access.
