2004 summit 600ho in shop, need reccomendation ASAP

[dlsteiner]

Just got a call from the shop and my 600 HO has low compression in one jug. I don't know the #'s but the sled has ~ 1800 miles on stock top end. What brand of pistons should I have the shop use for a top end rebuild?

Bill Cudney?
SPI Hyperdrive pistons?
OEM?
Wiseco?

Thoughts and opinions would be greatly appreciated asap as I need to let the shop know soon.

compression # in

The PTO jug has 25lb of compression, the other side has 120lb.

I've had great results in SPI in various sleds. Just did my 600ho end of last year with the spi/spx 'tmoly' slugs and it pulls like a freight train. I did use the BRP circlips with the leg on them, you need to take a bit off of the leg but there is no way those suckers are coming out.

04 MXZ- backcountry Mod's

Hey, I also have an 04' summit Mxz with a 144 track. Any recommendations for new track size and other mods to get this thing rippin in the backcountry?

When I worked at a BRP shop we used SPI exclusively except for warranty jobs. Never did one come back.

Im going to give out a shout for Big John. I have used his products and I have many customers of mine using his products on their own or I recommended John to them.

What I like about John is he is a decent size of business that is research intensive on his engine products and tests out on the dyno and field...can particularly tailor to an individual application. (rave springs/settings, base gasket, spark plug) all those little things that pull a few more lbs torque out of the good ol' 600's.

Shout him up on a set of pistons and a trail torquer kit for that 600.
With the engine down, you have a great opportunity for a tech head to point in a great direction.

John does good work!
