I know I wanna run a wet system, not to sure which ones are good and which ones you should stay away from. I know ya need an electric fuel pump, a hobs switch for sure. 10 jet spread with nos and alky. What else should I know??
Fuel safety switch is a good thing to have - prevents you from running too little fuel pressure which could result in being too lean
Purge kit is good but not a requirement
Teflon all your fittings, I used liquid teflon
Ensure proper bottle pressure, it makes a big difference!!
ALWAYS, ALWAYS, ALWAYS make sure your bike is properly jetted and tuned for the engine alone before turning the bottle on.
Timing can remain the same unless you plan to go big on the shot, then you'll want to decrease timing a degree at a time depending on how big of a shot you run. IMO, anything under a 25 shot is fine with your current timing, unless it's already on the edge of being too much advance. With this also comes checking your plugs. I would check mine during this time, after no more than 3 passes. If there is a problem occurring, you can try and catch it before it becomes major.
Always check your head nuts to make sure they stay torqued. When I was spraying, I would check my head after every 2 or 3 passes on the bottle, typically a few nuts would loosen a little bit from the pressure. I also would double check my cylinder base nuts.
Do not hot lap the bike on nitrous, let it cool down between passes. It doesn't have to cool totally off, but if it's hot, let it cool for a minute before making another run. Just safe practice to keep your engine happy, lol
Also, you don't "have" to do this, but I check my entire nitrous system out before every race. I pull the fuel lines off the nozzles and activate the system (with the nitrous bottle off the bike and disconnected), hit the WOT switch and make sure both lines are flowing an even and solid amount of fuel. My good friend Frank gave me the idea to get two coke bottles and stick a line in each bottle, then hit the WOT switch and you can see just how even the bottles are being filled. I'll usually hold the WOT switch until the bottles are half full. It's a sure fire way to make sure they're both squirting an even amount of fuel. If all is well, I re-install the lines to the nozzles, make sure all fittings are tight, then install bottle in bracket and check pressure, etc. Always make sure your battery is fully charged before a race.
That's all I can think of for now, I'm sure more will come to me later....it sounds like a lot but it really isn't...we're talking maybe 15 minutes of prep added to your normal routine
IMO the wiring of the system is probly the most important.. make sure you have good conections and the wires are ran away from pinch points and hot spots. I run a colder plug. I also love the WOT switch most guys run push buttons but Ive tried it and just LOVE the W.O.T. just one less thing you have to remember while ripping throught the gears.
