Finally got my first chance to take my sxr 700 out today. Sled has a fresh bender trail port. Primary has 89a's in it(not sure what rivet weights are in it) with a YGY. Secondary has green spring with stock helix at a 60 wrap. Sled engages fine around 4300 rpm's. Then when i hammer down it bogs up to about 5000 rpms and that absolutely RIPSSSsss. Any suggestions to get rid of the bogging?
Fuel screws? Installed at stock specs...

Try a tighter wrap on secondary
Just tightened the secondary up to 80 from 60. Still doing the same thing. I only had the sled out for about 3 minutes and the primary was hot. Im going outside right now to make sure i dont have a motor mount broken.

LIFE MEMBER ONLY ONCE!!!
belt is slipping then if clutches are hot.Have you checked your alignment and center to center .Is that a new belt or old belt your using?Carbs may need extra fine cleaning also..
Carbs are clean and back to factory settings....I just bought a clutch alignment tool but it wont be here for a few days. Where/how many motor mounts are there on this sled. I have the air box/carbs off. I can see 4 mounts. Two on the front under the exhaust flange, and too under the reeds. Looks like there is a torque limiter right behind the primary that the motor rests on but doesnt attach to. The motor is siting about a 1/2 away from the rubber. This does not seem right.
If torque mount it not touching your center to center if most likely off. My sxr is less then 1/4in
I meant to type in 1/4...not 1/2...and i actually just went and measured it, and it came out to be a little less than 1/4 of an inch.
turn your fuel screws out or put in bigger pilots
Just checked all motor mounts and they look good. Clutch alignment tool wont be here until this weekend. I will try turning fuel screws out to 2 and see if that helps.
I havent had a chance to turn those screws yet, but when i cleaned the carbs the fuel screws were set to 4 turns....Now that didnt seem right which is why i set it back to stock. Anyone who knows jetting have any idea why they would be set at 4? I called bender and the guy laughed at me when i told him this...

Did Bender give you any jetting settings for their port job? Try 2 turns out on fuel screws. Then try a bigger pilot if u get past 2 and a half turns out.
