READ A POST BY SPEEDZONE LAST SEASON THAT USING A 502 PLATE AT 146-65 DEG. WITH  IGNITION TIMING AT 0.80 BTDC WILL REALLY SPRUCE THIS SLED UP. HAS ANYBODY TRIED THIS SET UP AND IF SO WHAT WERE THE RESULTS?ANY FEED BACK WOULD BE GREATLY APPRECIATED.

THANKS

Ask any dealer the 96 500 was the best one out there,the wife had one that radar a best of 102 bone stock.There was a dealer near hear that changed the rotary valva and ran 105,not sure what type of rv it was.

AKFORMS - I looked into doing it but spent too much time and
money on my FIII to get to the SLS. I also spoke to Bill
Cudney about it and he recomended a similar set-up. Let me
know if you want the info? Post your results if you do the
work to let us know how it worked out.

my 96 500 sls will show 100 mph on the speedo on very hard  packed conditions and is bone stock. In 96 i believe it was the fastest 500 out there. Now i am running with 500 polaris"s that are quicker off the line and have more top end. I would like to get a little more out of mine if possible.
Maluchum, i would be interested in looking at the set up you mentioned as well

Here's the info I got from Bill Cudney:

Cut 7 degrees out of the RV plate and as for timing you can
advance the ignition 2 degrees to make a little more power.

RV timing of 145/63 and for all intensive purposes the 502

The closest valve to use would be the 501. When you use the
501 you can jet down 2 sizes from stock and in most cases
more just depending on the particular sled but a good start
would be 2 sizes down.

The difference between the two vlaves is not important even
when you install the valve a couple of degrees one way or
the other doesn't make a difference.
