Summit 670

[Deano670]

Deano, what's the reason for throwing out the oil injection?? Seems like such a pain in the azz to premix all the time.

Far more accurate per each cylinder, less weight(for what its worth),not robbing any power from the engine(again for what its worth) never worry about a pump or line failure causing engine damage. Lots of small things ruck that in my mind add up to be alot

Maybe... Got cpi pipe, roller secondary, 151 track, stock carbs, gutted airbox, ported, heavier primary clutch weights, (took off tricked out and ufo'd carbs - too finicky!)....still has oil injection, etc. And gearing played with..... What can you doo to it?

2000 rmk 800 with the big block not VES

 

[glengine]

Thats a good sled.. Need some NOS..

 

[dooryder]

I know and a light weight hood and seat, and i want to do a 159 inch track

 

[glengine]

yah the hood and seat would help alot.. Because a large weight loss.. I'll check at the shop cause we might have a good used track there..

Im curntly running a 144 but could i add an extensin to the rails and then move the skid back and put some no wheels on thatare larger?

Yah to go to a 159 alls you'd need is rail extensions, ones that are 7" long and then put bigger wheels on and you'd be good to go.. You wouldn't need to move skid back. You'd also need a tunnel extension and longer bumper which we have in stock also.

sweet thanks

Here is what your looking at Polarisryder...
This is my 2001 8000 RMK.
Ported and Polished with higher compression (read as 50/50 race fuel), pipes, and reeds and some lightweight parts and Mods Skis...goes like stink.
Went from 151 x 15' wide x 2" to a 159" x 16" wide x 2" track - Huge difference in climbing.
Added the light weight hood and venting kit this spring.
Along with mods come problems from time to time...in this case I had a head gasket go...minor $75.00 repair...my fellow riders sure enjoyed towing me out of McBride...lol...
