Help - What smaller engines will bolt into a 2004 Rev 800

[dwwinters]

I have a high milage 2004 rev summit X that is not worth too much to sell due to the milage on the odo (engine is lower rebuild). It has reverse and I can add an electric start easy and cheap enough for my son. He is ten years old has rode it quite a bit on lakes in powder but I have not set him loose on a mountain alone yet. For both power and weight reasons. Could I bolt an older 500 or 600 engine in and use the clutches electronics etc? And keep the 800 engine for him a couple years? There are lots of 13 year olds on 800's here kicking dad's butts but he is too young now for all that power and weight.

Or is there a way to limit the power on the 800 and still make it run good? Even with an 800 it's still a pretty light sled compared to most older 600's

Again it's just an idea to save a decent sled. Unless someone in or around BC has a high milage M6 they want to trade.

Thanks for the help.

A 600 REV engine should bolt right in. May have to have the MPEM altered to run the 600, but don't know that for sure.

honestly...the 600 rips very well. i dont think it matters if you use a 6 or an 8.

not to mention the hassle...differant clutching..exhaust system...computer system...carbs...

unless you can find a COMPLETE running engine package..

then yes it will bolt in.

If i were you i would just keep that engine in there and just mess around with the throttle to allow only 1/2 throttle when the thumb throttle is pinned. That way he wouldn't feel all the power and you can gradually increase the amount of throttle as he grows into it

I'll send you my clutch kit! Sure to cure a good running sled!

440 bolts right in and they have 100hp trail converted. Complete motor packages with exhaust, carbs, electronics can easily be found for under $500.

 

[maxwellzx]

where?

 

[dwwinters]

squidward - that's a great idea. Thanks

Will the 440 trail converted run at altitude or is it going to be a tuning nightmare?
