My bike is getting fluffy - jetting for everyone over summer

As the weather gets warmer you will find leaning off your jetting will keep engine response crisper! The hotter air becomes thinner meaning you need less fuel to make it work efficiently.

With four strokes, look at winding the fuel screw in 1/4 of a turn if the bike seems fluffy (as I hear people call it) or it bogs when trying to crack the throttle while riding. This will lean your bike up around idle.

Also raising the clip position 1 groove on your needle will help response from 1/4 to 7/8 throttle.

For two strokes, wind the air screw out 1/4 of a turn to improve throttle response off the bottom. This is strongly recommended 3/4 the way through a dusty hot ride!

Again raising the clip position will also help overall throttle response if it is running rich or not coming into "band" like it did over winter.

just to add to that if you live in a dry climate with no humidity. your mixture will be leaner so take extra care leaning out your needle and main. but buy all means lean out your slow jet for desired throttle response.

Keeps it singing on the pipe nicely

It says in the GAS GAS manual that your meant to run them half full of oil in the summer to keep them cool

What about putting ice cubes in your airbox, to cool the intake air
