nitrous on a motorcycle

[BVCBR]

Edelbrock, and I'm sure all other Nitrous companies, offer blank jets. You can drill them to any size you like. The Edelbrock part number is 73013 for Taper Face Jets and 74000 for Funnel Jets.

Does running nitrous put you in a different class/category?

YES.. anything "other than" GAS bought from the track vendor puts you in FUEL Class..

So adding Nitrous puts you in Fuel class no matter what else is in your tank.

The engine likes timing .The more I advance the timing the more fuel it burns and the more power it seems to make
 

You need to find a way to retard your timing when you spray or that will be the last run that engine is likely to make. It sucks that MSD can't read your ignition unit because they make one that comes on automatically when you spray, but they aren't the only ones who do.

no not really.... if yer spraying less than a 50 shot there is no need to retard timing..... but some people like me think spraying anything less than a hun is a waste of time.

I have an ignition system called a BRT-Tis . I have a switch on the bar. I can select between two maps on the fly. When I make an all motor run I have close to 43 deg of timing across most of the RPM band.
When I spray nitrous I will start with 35 deg across the entire RPM range ( stock ignition curve ) and work from there.

Have you tried these guys for an ignition unit?

I have one, not installed yet, about 150USD I think

Thanks for the link . I will look at that.

The BRT is made just for the 250 it is a fully programmable unit and has two maps that can be switched on the fly or with a relay when I spray.
It has a programmable rev limit up to 16000 rpm and the ignition curves are programmable in 16 steps.

In case anyone wants one It is available from Spoptisimotousa
