hi all new to forum , got a question, just aquired a 02 rubicon, had an 03 kawaski 650 traded even. the rubi is in great shape has 1100 miles on it yesterday i changed the oil and spark plug and oil filter. i used honda gn4 oil and honda oem filter. my problem herein lies, before i changed the oil the bike ran great, it still runs great however the, when i went riding after the maintanence traveling around 30 mph , i cracked the throttle and the tranny slipped a little bit . is this normal after an oil change?any suggestions? thanks love the forum ive learned some cool tricks so far.
