OK so, I have a 2009 Sportsman EFI. Story goes it was owned by and older couple who only drove it around their yard. Unit had 1070 Miles when I bought it from a dealer. I put 200ish miles on it and it started missing around 4000rpm, but picks back up after, and has little to no hesitation on a hard launch. Changed the oil and noticed a ton of silver, Thought my motor was trashed. After performing a COLD leak-down test, I have confirmed the motor is still good. I don't think this thing was ever ridden hard enough to do a proper break in...I am hoping. Ive checked for a leak around the injector, nothing found. (Used ether to check for leaks) I did adjust the valves to .006 Intake and Exhaust. Checked the battery terminals, those were good. At this point Im thinking its an electronic issue. I have seen guys talk about T-bap issues? No idea what that is to be honest.
Any hits or tips or tricks to check would be helpful! Please let me know!!
I have a mechanical background this thing just has me stumped.
