How much is to much compression? Please make suggestions...

I have 2 Sxs and have set them up with a stock single exhaust and with tripples as well as two seasons with a BB 800, here's some of my suggestions.

When using the stock single exhaust:
-don't waste your money on a boost bottle
-installing reed spacers is a MUST
-use Carbon tech reeds in the stock cages[no need for Vforce]
-1 layer off of the head gasket works very well with stock head and premium fuel-
-I also had good luck with the airbox mods but a lot of people will not agree with me here[tech pages]
-adjustable transfer rods are a must
-a good 1" track I found to be the best all around compromise and does not create any clearance issues
-if you have no noise restrictions issues, I found modifying the exhaust canister to help performance a bit[tech pages]
-with stock porting and single exhaust these redhead tripples have a very flat/forgiving power curve but mine ran best when clutched to shift out at a MIN of 8300 and a MAX of 8500RPM
-I found the 99 700 SX to be geared pretty well right on at 23/40 although I occasionally used 22/40...both worked well just depends on conditions
-once you have all the other work done work on the clutching...these SXs really like to over rev with the stock setup. I found both of our 600 + 700 SXs would pull a lot more primary weight and or secondary helix angle then stock...the tech pages have recommendations on this, I no longer have the notes on my setup but I do remember that I only added weight to the tips of the stock weights.

These SXs really do work well with a single pipe when properly set up.

Its get confusing, only because there are so many differences of opinion! I will check compression again with different gauges. I will post hot and cold compression. The head gaskets are in-tacked with all three layers. I will be clutching it also for aggressive trail riding and my weight.
I will be running a single pipe (stock) and "cut" can (as per tech pages), do to aftermarket exhaust restrictions! I have a 1'' track on it and adding 144 Woody Gold diggers 1.075'' w/aluminum backers. Lots of ice and wind sheared, snow covered fields in the finger lakes area of New York. Picks are a must for stopping and getting up hills!

Thanks Again,

Brett

I'm sure it would! I would love the 25HP +or- but NY state checks for aftermarket exhaust! They ask you to open your hood at trail stops and check the year make and model. If the sled came with a single pipe you get a ticket for altered exhaust. They can impound your sled if they want to, on the spot! Brother in-law is a county sheriff....

There was a member on here who had a set. I was going to buy them from him but after hearing the laws on it, I decieded not to. First ticket is $250, 2nd $500 and the 3rd is $1000 fine. People still do it but I have better things to spend the money on. Love my country, #$%&* dislike my government!
