"RED" hot header??
Posted October 29, 2006 - 10:48 AM
Jet needle adjustable on 3rd clip
Pilot jet 48
Pilot air jet??
Starter jet #65
Leak jet #50
The bike he states is very high performance (since it was to be used for a desert race) and will burn up if I try to run it at my elevation...he had 103 octane fuel in the tank when I bought it last week..anyways during my mechanical check on the bike I removed the BAJA 4 gallon tank and all the fuel leaked out overnight (don't ask how... that is not the point here:banghead: ) I filled up the bike with our canadian premium at 91 octane...started the bike and in about 4-5minutes idling the powerbomb is glowing red hot...
The bike runs fine..doesn't do the lean revving when opening the throttle (open the throttle..then close it..the revs drop with the throttle and don't get "hung up" as in a real lean situation)..the bike starts easy but the header glows red...I moved the needle jet to the middle clip and I know that has hardly anything to do with the idle but I tried it and it runs red hot again...(needle jet is for more at 1/4 to 1/2 throttle)
Any suggestions...I put a bigger main in at 180 still the same...so does the pilot have to be bigger ie.60 or 65 from a 48..maybe a smaller pilot air jet??? not sure but any help will be very appreciated...
I am wondering if race fuel at 103 will make the bike run cooler???
All this is at idle no driving at all...bike is very snappy at the throttle no bog just quick response...not sure of the cam put in?? The AIS has been removed..has a high flow air filter as well...

I am surprised you needed to go up to a 50 pilot jet, but perhaps that is due to the mods the previous owner completed.
I live outside Edmonton and run a 48 pilot, but I am still using the stock exhaust. I am gonna try a YZ exhaust on it in the spring (or maybe when it hits plus 10 on Xmas day:thumbsup: ). So I'll follow your lead and have a 50 pilot on hand just in case.

The last owner had the motor blue printed, new cams, piston, titanium valves, done on the bike...I am still waiting on that paper work of exactly what was put in...thanks for for the 103 octane information...makes sense and once the snow melts here it is time for a rip...I will keep everyone posted...
as for the 50 pilot jet...I am sure it will work well by adjusting the fuel mixture screw...
Thanks for the input and patience guys and gals!!!
