I'm doing an ear shave this spring - I removed the airbox - coastered the clean air system. to get the filters k&n 2340 the best pricto make it easy to remove the carbs. To get the filters k&n 2340 the best price was amazon.com free shipping. T oget the correct jets contact lance with a personal message. He will need to know your exhaust system, coastered or not, type and make of air filters you will use and maybe your altitude. you need 2 piolet jets (idle) and 2 main jets plus needle shim washers.
Read my post on easy air box removal. GOOD LUCK
