Probably. I recommend plugging at the "T" because I prefer blocking individually, but it's personal preference, that's all. As long as you got it plugged, you're good to go.
Someone posted earlier that the older (2001-2005 600's) and the newer 600's take the same exhaust spring, so no need to change springs on the 600???
I know on the 800's the exhaust springs are different old to new.
Kravan, thanks for taking the time for all of your EXCELLENT posts on Snow-West & HCS!!!
Since last year I have been considering plugging the exhaust valve's black rubber hoses on my 2009 600 CFI-4 Switchback with SLP pipe, SLP can, SLP MTX weights, Gabe's Team secondary set-up, my cheap high flow intake, etc. As I can fell a large power surge at 7500 RPM, runs strong to 8400 rpm. Is this power surge from the SLP pipe or exhaust valves opening up late at 7500 rpm???
---I think the 7500 rpm power surge is from late exhaust valve opening to improve EPA.
---If my memory is correct the 2002 600 Poo's exhaust valves opened at approx 6900 rpm.
---If my engine's exhaust valves open at (7500 rpm ?) it has to reduce mid range power and increase heat to pistons and exhaust valves.
Quick easy, looks stock:
Today I removed the two rubber hoses off from the exhaust valve assemblies nipple, which measured .243" O.D..
---Then I cut a .250" dia bolt into two smooth .75" long pieces.
---Then pushed the .25" Dia x .75" long smooth bolt pieces into the end of both black rubber hoses.
---Then pushed the rubber hose back onto the exhaust valve nipple, pushing in the bolt piece. Added a extra clamp to hold, seal off the short bolt piece.
Note:
---2009 Switchback 600 CFI-4 exhaust valve Purple spring #7041704-04.
---2002 600 XC exhaust valve pink spring #7041704-03.
