RKT 738 w/ a 600HO SDI??

[rotax]

So, sorta pondering going this route.

BUT, not sure if or how this would work with the SDI?

Are there any out there?

I like the idea of SDI, but not sure if its tunable enough to make work with a BB? Are there BD boxes for these sleds, etc?


The 734 built off my 700 was flawless. So, wondering if this would be an option w/ the SDI.

Sorta, looking to get back into riding snowmobiles in my spare time instead of wrenching on snowmobiles all the time...

If you are set on keeping the 600 (not upgrading to an 800) the RKT kit would be awesome. Their stuff really works well. As far as tuning the EFI sleds are much easier than the carbed sleds. I have a PureLogic box on my
07' Summit 600 SDI with a Turbo. I was very surprised how easy it was to tune.

Talk to Ski "doo'in it"(sorry it I butchered it Nick!) He has a carbed 600 with the RKT BB on it, runs AWESOME! As for the SDI, does Boondocker or someone else make a control box? With the cheater head, would be a cool sleeper sled!

Thing is, I'm not 100% convinced the 800 is an *upgrade* per-say...

Reliable and consistant 140-150 HP (w/e u wanna claim it to be) would be better than some 800s/mods I've seen/dealt with.
Specially on the XP platform?

Are you having trouble with your 840?

well, not this season. yet. hasnt been ridden this year.

i may have been spoiled w/ the last engine i had, much more forgiving..?
or maybe i just made a stupid mistake in tuning last season, but still have my pov on certain pistons..
we'll see how it goes once i get some more time/tuning on it this year.
i may just be overly picky w/ tuning...but at the same time i need to be able to make it a day w/o having to run 15+ gallons of fuel through it.

the 73# is a sipper in that respect!
