I have a can on the sled, any specific fuel regulator? Not the brightest on snowmobiles slowly getting into it, just wanting some more power, I was gonna try and get some zr700 pipes and stuff them into the ole 96 ext, worth a shotNo on the chip!
Open up the stock exhaust box,
Oval out the pick up coil mount holes (advance timing)
And adjustable fuel regulator
Personally a bit of flow porting helps alot!
How do you get an adjustable fuel regulator for one?A sour subject but I built a 98 EXT many years back!
The 580 can be bored out to a 620?
The stock can had the Black Magic rework
Heads were turned, case and cylenders were ported!
And of Course it has my adjustable fuel pressure regulator complete with gauge!
It was very fast! 98 mph in 500'
