jetting

[indy500]

ok on warmer days my sled boggs out on take off, my sled is from ontario and il living in newfound land were the climate is a bit warmer(could it have diffrent jetting), im thinking the problem is in the pilot jets,would it be safe to go down a size?

Whether it is safe is for you to decide. Look at the plug color after you change jets. Run it for just a little and then check.

Brown is good
White is too lean and you'll burn up
Black/oily is too rich

There is a plug color guide somewhere on the net - it gets posted from time to time, if anyone remembers where, please post it for him

There should be a jetting chart on the clutch guard or in your manual. You should be OK jetting down a size though. Also, pull the jets and make sure they are the size that came on the sled stock and go from there.
