I was wondering on the K&N air filters if there was ANY difference in size???? For those of you who know, you even have to struggle to fit the old one in. Also, would you tell any difference in power??? This will be my only modification to it and this will probable be the only one for a little while. I am trying to do a tune-up and want to go with something better than stock. One last question..... Will I have to jet or adjust the carb if this is my only mod??? I really dont want to get in the woods and it start bogging down... Thanks in advance for all answers...

 

better then the stock on,,,,yes ..will you notice a difference no,but if you intsall a dyno jet you will see a small difference..

 

Is there ANY difference in size and is it required for me to adjust or jet the carb??? Would it bog down if I didnt?

 

i bougyt my bike withe the motor in different boxes, so i never knew how it ran before..i had to go to a .40 over weisco and seeings how the air filter was missing i bought a foam UNI- FILTER and the air box snorkel was missing and also replaced the crank seal and intake boot and went through the carb.. well now i had a quick little bike until it got warmand then it would start pinging(hot)....sooo i called up RICK RITTER of RCR raceing and told him what was going onand he told me to put in a 140# main jet from i think a 130#.. runs great now.. it dont seem like just a air filter would make it lean ,but i would check the plug if it ran ok just to be sure..
