    If it has a motor I'm interested
  1. I purchased a 2007 BRP last fall. The bike was purchased from a previous owner who said that the bike had been uncorked, and jetted for higher elevation(8-9k ft) in southern Wyoming. I never rode it at that elevation or heard it run. I brought the bike home to a lower elevation in Wyoming (5k ft) and noticed that after 100-75% throttle to 0-25% throttle (quick decel) the bike had an excessive amount of popping and a continuous pop all the way through the decal (the faster the speed the longer the popping). This is only when using the compression to decal as well. There is no popping on acceleration. It feels to me that it has plenty of power all the way through each each gear with wide open throttle. The PO said that he never experienced any popping on decel (he seemed to be an honest person but take with a grain of salt). At that time I tried replacing the main jet which was a 165 to a 168-172. Each one after 168 progressively made it hesitate on acceleration especially on top end and pop just as much on decel. Maybe a little less in frequency but louder. I left the 168 in due to it performing a touch better. I recently moved to North Dakota (1.5k ft) and the popping has stayed the same. Today I did a full investigation for myself of the bike and the mods that were and were not done. They are as follows: main jet = 168 pilot jet = 65s Intake = non-restricting (no D) muffler= i think stock with a different tip. Maybe drilled out? see pictures. number on muffler is Honda HM MBN A1 Throttle needle = stock. only 2 clip positions, not 5 like 2006 and before. Air Intake = removed restrictions If you would like any other basic information please request. My question is where to go from here. I just purchased a 175 main jet, a B53E needle which I will put to the 3rd position from top, a 68s pilot jet, new header gaskets, and all new gaskets for the rest of the exhaust system (just in case it's a leak). I have not put the items in because I have not received them and I am curious as to what this forum thinks. I have not adjusted the mix screw and do not plan on doing so unless needed later ( need the special tool). I am a beginner when it comes to working on bikes, but I am pretty mechanically inclined. My goal is to have the bike run well with minimal to no popping on decel. I hope I provided adequate information, and if you want to know anything else please request. Any help would be greatly appreciated, especially from Moses the admin. Seems like an awesome guy. I can upload any pics as well. Thanks in advance
