do i need to upjet my yamaha qt50 with k and n air filter?

just got a k and n slip on air intake for my yamaha and took it for a ride and the engine sounds as if its going downhill like as if the bike is moving too fast for the engine to handle. it does not sound good. however the bike itself is way faster it has like a 10mph+ increase. also after the ride the bike was smoking. i read that i have to upjet the carnburator which i have no idea how to do. if someone could tell me how to upjet that would be good thanks (:

John you are going about this the completely the wrong way. Yea some of us are older but this is a hobby. You will learn in time that people ask these same questions all the time.(this being one of them) Crap I still do it. Google it I hate reading but if I want to learn I have to do it

Not sure why any one would need to up jet with this filter. I can run with out a filter with no problems at all. IMO the stock 70 jet is a little rich for the stock filter from the factory. So a better flow filter would be a better match. Just like running a stock filter runs better with with the 65 jet than the 70. Assuming all other part are tuned and working properly. Clean the carb first check the jet size, should 70 or 75. Try not to be a dick most of these OLD DUDES have forgotten more about ped then you will ever learn. jet is #4 (edited)

Re: do i need to upjet my yamaha qt50 with k and n air filter?

yea im so mad i could punch a hole in a wall

Re: do i need to upjet my yamaha qt50 with k and n air filter?

Not sure why people get so pissed about a question. If you don't like it leave the post and move on to something you like to read. That being said, try the filter as is. If it is running lean (bogs or sluggish at wot) move up to the next size jet and try again. You may also need to work on the mid range by moving the needle in throttle slide up a bit. But get the wot nailed first if it does not run right with your new air filter. Don't run it too long if it is running lean...not good for your engine. Read about tuning for more detail and less abuse. Good luck.

stock jet will be fine, upjet when you get a pipe.
