A few things, Check belt deflection, I would check Plug colour and piston wash to determine if it's jetting, Jetting chart after new 3deg timing keys will change, lean or rich not sure but I think they lean out a bit on stock jets with advanced keys, This might mean your primer (Air, Fuel) jets will nead adjustment as well. I was told I might loose a bit of bottom end with the 2 degree but have not tried it as my shocks are getting redone. Good luck, try giving Doug a call at Don's Speed Parts, They distribute D&D in Canada 1 800 431 CATS

If it's a F7, it's not the jetting causing the problem, it's the timing key. Put the timing back to stock and I guarantee the problem will go away.

What Jets? It's an EFI.

That's what I was hinting at

 

[northeaster]

he has the f-5 thats why it didnt click for snow blind

 

[jbscapitol]

if it is a f5 it will never pull 63 gram weights or 23-40 gears even a f5-720 won't pull that. It may be a low end lean spot causing the hesitation no way to fix it on a efi. Start taking parts off and adding back on till you find the problem. Did your sled do this stock?

A friend of mine installed 6 bullseyes and it caused a lean bog down low. He caps 2-3 to get rid of the problem. Maybe the sled isn't all that rich after all.

Thank for reply,no esitation before,will try to plug 2 of 6 bulleye,

Get the Timing Key out of the F7...It WILL cause problems down the road. Saw two F7s come into the Dealer with ONLY a timing key in them with seized engines.

did you pull out 1 shim from your secondary? I had the same problem until I did that. good luck!!
