How long dose a bottle of NOS last??
Is it ONLY good for straight shots and drags??
Would it suck for a woods rider??

 

mpeek...um, just making sure you know this, your post was unclear, but NOS is a holley brand

 

I assume they have you t off of the factory fuel line or spigot? Would'nt running a dedicated fuel line from the tank to the pump fix this?

 

ON the stk piston? What jets would yeild 25hp?

 

I have a NOS chart

16n/20f 9bhp
18n/22f 12bhp
20n/24f 15bhp
22n/26f 17bhp
24n/28f 20bhp
26n/30f 23bhp

For stock piston, I wouldn't go over 20bhp . It will break the ring lands off your stock cast piston. I have one for proof.

Thanks! Looks like i got the NOS kit for $150 plus shipping! Funny, i was on a Hayabusa board that i've been on for quite some time and noticed this kit for sale! Should be fun on the DS!

 

First of all Bom is right. I think 20hp is enough on the stock piston. 25 Hp is what I ran and did fine but my valves did tap the piston from being over rev. The most important part is making sure you keep everything clean and free of particle obstruction. If the fuel pluggs...........BOOOM. Also monitor your bottle pressure very closely or you will NOT acheive your best performance. I recommend a good bottle heater to help maintain propper pressure. Also start looking for an extended swing arm or wheely bar, you'll need it!!


As for woods riding, I think Nos would be pretty well worthless.

 

Cool, thanks guys! It will be here sometime this next week. It will be a few weeks before i install it. I'm waiting on my pipe to get here and then i'll install it and the carb. Once that is up and running well, i'll add the nos. I'm sure i'll have more questions once i install it(maybe even before!!!).
