I have been lurking on this site for a while, This is my first post. That said, I have owned and worked on SOHC Honda's years back, With a big Vintage bike scene in my area lately I have caught the SOHC bug once again.
I would like to help a little reguarding Nitrous use. I have been using Nitrous since 1984 on both cars and bikes, since that time I have used 100's of pounds of nitrous and been involved with a number of Fast 'Street Car Shootout" wins. One thing that I see is that there is still much confusion about its use. I will try to help people to understand a little about Nitrous use.
Things to think about.
1 Nitrous can be completely safe, IF (the big IF) used within limits of the engine design and strength and NOTHING goes wrong.
2 (in simple terms) Nitrous does NOT burn, It does not add power by itself. It allows the use of additional fuel which actually makes the added power.
3 When Nitrous is used, the engine requires added fuel from somewhere, be it a pump and injector or a overly rich mixture to start with.
4 "Dry Shot" systems don't use a pump but still needs extra fuel to make more power, so typically the carb is jetted rich to start with.
I will try to help any way I can.
