I geared down to 19/42, and put 58 gram weights in the primary. I run 8000-10000 ft. I also had the primary balanced at SLP and shimmed the weights with a comet shim kit. It screams now. It ran good before, but now it out climbs rev 800's and hangs in there with rev XP 800's. Worth every penny wish I had done it from the day I got it.
Changed gearing and clutching on 08' 700 Dragon RMK 155"

Shhh!
That's how I run mine too. It's rocks!

Do you need a different chain when you go 19-42 gearing. Thanks

I actually just did the same to mine, made a huge difference. stock would only pull 7900rpm now with the 58 gram weights and the gearing it pulls 8300-8400 on hills. Made a huge difference
19/42 gearing allows you to reuse the stock chain.
I was running 7900 RPM max with the stock 60 gram weights.
Now I'm running 8250 RPM max with the 58 gram weights.
Thinking about changing my primary spring to engage at higher RPM.

i went with a blue/pink primary spring and seems to work good
Same mods on mine 19/42, along with better boards and a MBRP can Recently I replaced the exhaust springs with the yellow (lighter) ones and I am impressed with the small but noticiable difference. I have the 60g weights still and run about 8000-8100 rpm. I might consider the 58's. I ride at the same elevation. Love the sled although I am concerned about all the regulator/ecm issues. I hope its a really isolated thing. Can you tell me what helix you are using, as well as your drive and driven springs.
Thanks
Thanks
Helix and springs are stock. SLP balanced the primary and it must have been way out because the drilled several holes on both axis.

why did you change the springs just curious also what elavation are you at. i also thought i remember somebody saying about pinching off the line that gos to the exhaust valves and gaind some power anybody have any input
I plugged the purge hoses coming off my ves valves ('08 D7) and it did improve excelleration through mid-range, also put a lime green team primary spring in (increased engagment 300 rpm and about 100 rpm through shift out) works great (8-10k) stock helix and a red black secondary spring.
I changed the exhaust valve springs on mine simply because one was broke. I found it after one day of riding, the machine kept stalling after hard pulls on hills and so forth. I started checking all the obvious things when I got home and ran across one of my exhaust valves not working smoothly.
The stock springs are pink, I went to yellow which are have less spring rate. I would imagine this accomplishes a similiar effect as capping off the solonoid control. I may try blocking the hose as well.

how wide is the stock chain on a 08 700 RMK
