i see he has a nos piston. but will the reg 11.5 work.

 

Well I have about 2 - 2 1/2 lb bottles through my bike with the 11.5 piston (it is more like 10.5/11 to 1)and it has been great. I am running the boondocker kit so it is not as rough on the engine as a wet system but still makes good power. 650 viper has a ton of NOS through his bike on the stock piston and it runs like a champ and the stock piston isn't as well made as the woods.

 

A "wet system" is not hard on a motor. As long as it gets the right amount of fuel and your not giving it more then the stock piston can take, it will last just as long as it would without n20.

The woods piston is great for n20, loosen the ring gap and give it about a 30-35 shot. Once you do that you'll wonder why you never used n20 in the first place.[img]i/expressions/face-icon-small-happy.gif[/img]

 

I think you run just fine and dont really need NOS[img]i/expressions/face-icon-small-happy.gif[/img] just my .02

 

DSaholic how do you figure the Boondocker kit is less rough on an engine?

 

Yeah Id like to know a little more about the boondocker system.

 

This is off of the site and makes some good points about the system and why is it safer and a better choice for some one that wants to have the power of N2O but doesn't want the complexity of a wet system.

" After extensive testing, Rocky Young found it very difficult to get consistent results when injecting nitrous and fuel together in the conventional way (often resulting in engine damage). Then Rocky discovered that by injecting nitrous into the airbox, the engine consumed only the nitrous that was needed when it was needed, and by increasing pressure inside the carburetor float bowl at the same time, extra fuel could be delivered simultaneously. This was the only way he could produce consistent and reliable results using nitrous on a snowmobile - ventures into far off, hard to reach powder bowls could now be undertaken with confidence! Rejetting is not required, the extra fuel pump and fuel solenoid are eliminated, and the bottle heater can be eliminated (nitrous and fuel delivery both change with bottle pressure, so constant N20 pressure is not as critical). Rocky also discovered that when nitrous is sprayed from any conventional jet that is made from metal, N20 ice crystals are produced which can quickly damage an engine. Considerable time was spent researching and developing the Boondocker Nitrous system so it will disperse nitrous evenly and consistently without creating N20 ice crystals"

I guess that it might not be any less rough on a motor but it sure seems safer and less parts to fail than a wet system. I am not saying that is is better than a wet system because it isn't when it comes to making big power. I have seen a lot of N2O bikes run that have wet systems and they haul some butt (jeff's, sandmans430's). I am just saying that for the average duner (like me) that wants to be able to play on the hill and kick some YFZ butt once and a while this kit might be a safer and more cost effective choice.

To me is seems that how the system works would be a bit easier on the engine and after seeing both systems run and how the N2O comes on I seems to me that the boondocker kit is a little less harsh of a hit and much more consistant when it comes to fuel and N2O mixture/delivery.

All systems have the posability of failure but it would only be logical to expect a system that has eliminated a few parts prown to failure to be more relaible.

Anyways that is just my .02$ and the reasoning behind why I went with the kit.

Here is a link to there page that has some real good info on there kits.

Thanks and I agree with you.

 

Sure, glad to help.

 

All of the Wood Racing pistons for the DS are now set up to use nitrous.
