Anyone run nitrous on their 250r? What kit works best, this is a hillshooter that it would be going on with a 370 motor.

Gas or alky? I've always wanted to try but I run alky and not a lot of people I know ran it with alky. A buddy has a kit for an oem cyl and it flies but it's race gas

I have seem guys using it. Last guy looked like he had just seen a ghost. I bet it is super fun but alot of wear and tear on the piston and crank.

I ran a NOS single cylinder kit on a stock 250r. It won't hurt anything if you don't get crazy trying to spary to the moon. My kit
had one fogger in the intake with a nitrous and fuel solenoid and a fuel pump.

i'm running vp110 fuel
and i was looking at the boss noss kit and i would only do a 10-15hp shot.

I never tried one of there kits. Seems like the snowmobile guys like them. I would rather have the fogger in front of the carb. I think mine was setup for a 9 hp shot. I had a 2lb bottle and it lasted a long time. You will want some kind of microswitch on the throttle to trigger it automatically at wot.

Nitrous oxide systems and NX used to make them. I ran a small motorcyle battery. It ran a electric fuel pump and both the soleniods. I don't know how the boss noss kits work. I always say them installed in the airbox. I assume they are just a dry kit spraying nitrous only and not adding fuel. Mine was a wet kit so i could control extra fuel and nitrous together.

what about jetting? or does the wet kit just blend it so jetting isnt an issue?

I never changed my jetting. The fogger has a fuel and a nitrous jet in it. It looks like the boss noss kit is a wet system also. You may want
to give them a call and see what they offer. You may have to retard your timing depending on how much you spray. I never changed mine.
