I dropped the jets in my carb 1 size in my 600 HO. Two nights ago it was 5 degrees F. I did two full throtle runs down an air strip on the last run I shut it down at full throtle and changed the plugs. The plugs that i took out are a little lighter than cardboard maybe half a shade is this to light? I would post pitures if I can figure out how.

Thats pretty light. I would opt for peace of mind over all out performance and go back up a size or two.

That 2nd pic is a lot better. Yep! That looks about right! Nail the throttle and dont look back.

those are almost perfect for a sled with DPM. A really tight tune will be even lighter and no problem at all.
If you only dropped it one size you have nothing to worry about these are way fat from the factory.
