problems with a 1997 700 rmk

[rmktime]

my sled is idaling at 1800 just about dies drops down 2 5,600 but doesnt , also my secondary is kicking in at 4200 is that good or bad , any help would be appreciated , and yes i know buy a yammy or a skidoo or a cat but cant stuck with the polaris till i win the lottery

Engaging at 4200 isn't bad If I recall my brothers engages at 4500. Have you checked your reeds and boots, they could be cracked

I have the same sled, check all the obvious stuff first. Sounds like your just losing 1 cylinder after it warms up? If plugs, cap, wires, spark controller, reeds, boots and carbs are good I'd look at the crank seals. I had a problem with mine that sounds an awful lot like what you describe and it turned out to be the mag side crank seal, had a chunk out of it.

Those 97 and 98 700's were some of the best engines polaris built. (And I do hate polaris:d)

kinda sounds like Crank seals bad on PTO side,spray some WD_40 behind the clutch while its running, if it runs faster, seals Gone,
if that doesnt change anything
do a Compression check, that tells all.if one is real low, under 100 and other is about 150, rebuild the motor.
I had a 700 for few years, always changing pistons in it, till I found out the crank seal was bad.after that,it was fine.

These are some of the most bulletproof engines ever made. Last year we installed a Vari-Flow on my '98 incorrectly which caused it to run insanely lean. (To the point where I actually beat a 670 in a race. lol) I still put on about 400 miles before I melted down the piston. Amazing reliability in these engines. Before that it had about 5800 miles on it as well.

When was the last time you had the carbs cleaned and sync'd?
