Full Version: How to tweak 600 ho engine?

Hi all

I have a SB 600 HO and I really love this sled.

I have a slight bog when I hit the throttle at idle. How can I get rid of this? I usually ride at around 1000-2000" with temps around -10 degrees (upto -20 degrees celsius).

I plan on buying the SLP pipe/can combo this summer, so I guess my best bet is to wait until then and rejet and clutch it as required. I trust this will solve my
low end bog?

Other than that my engine has been great. Top RPM is 8400 and it holds the RPM around 8300 RPM. Top speed on crappy conditions is 96 mph so far.

With Stock pipe and air box, change the pilots from 50 to 45 and turn fuel screws out 1 turn.

Polaris missed the boat on the bottom end calibration on the 600HO imho.

sounds like you need a gram or two in the primary , most guys say they pull better a little lower rpm then your running.
