what do you do

get ready for grass drags if you are running an edge sled. im not sure what i would need to do as far as jetting because the chart just shows 50 plus degrees and one jet size. im sure i need to go up 2 sizes or so. it will need to be for 85ish temps.

its on an 02 700 rmk

if that makes sense to anyone i would appreciate any input
thanks

That a good question. I used to race in the summer, but I never re-jetted but then again i had a piece of crap older sled so I didn't care. I'd go up two and see what the plugs look like if you have a practice field to try it out. Heat kills ya know!

You need to jet up (larger/richer) for cold temps and down (smaller/leaner) for warm temps. Your jetting chart should show smaller jets for warmer temp ranges and larger jets for colder temp ranges at a given elevation. Cold air is denser than warm air.

What elevation are you jetted for? If you're jetted for 3000-6000 ft and -20f to +10f temps, then you are probably a little too rich for sea level with warm temps. If you're jetted for 3000-6000 ft and +10f to +40f temps, then you are probably pretty close to where you need to be.

Figure 1 main jet size for every 20*F and for every 2,000ft elev change and you will be real close.

yeah i meant to say jet down. it will be in the 0-3000 ft elev range. im sure it will be more trial and error type of a thing, but thanks for the info so far and keep it coming

do you have any lists of grass drags in SD????

 

[sledmanhof]
