I just advanced my timing 4 degrees, and immediately noticed the engine was running quite a bit hotter. I picked up a radiator cap temp gauge, which shows I'm running in the high 180's/low 190's at idle, which quickly increases to the low 200's after a quick pass or two (2-3 minutes). I checked my impeller (looks great), drained the coolant and added engine ice, which helped a little bit (about 5 degrees). I never actually measured the engine temp prior to advancing the timing, but would guess I was running in the 160's.
I did a carb rebuild soon after buying the Banshee with stock settings, air screw two turns out. She idles fine, but now when I blip the throttle, there is definitely some bogging in the first 1/4 throttle. When I turned the airscrew 1/2 turn back in (clockwise), it got rid of the bog, but caused my idle temp to quickly hit 215 before I shut her off.
I would like to dial my carbs in before addressing additional cooling issues like a cool head and new impeller. I just need a starting point suggestion (mains, pilots, needle position, etc), and can tweak from there.
Here are my engine mods:
Bored .020 over
Pro Circuit pipes
Airbox lid w/holes and K&N filter
+4 timing
Premix 32:1
Thanks guys.
