CrashFireBanshee Posted July 8, 2004 Report Share Posted July 8, 2004 I am trying to jet my trinity 2-1 intake with 34mm PJ carb. I can't seem to get the right piolt. I bought it used and it came with a 68 pilot. Which seems huge to me but it won't run unless I have the idle adjustment almost all the way out. It acts like it wants more fuel. Is this normal for PJ carbs. Now I have no choke because the idle adjustment is all the way out. What other problems should I look for. Should I just go for a larger pilot? Oh the air screw really has no effect on the whole thing.

sredish Posted July 8, 2004 Report Share Posted July 8, 2004 Sounds like you want a smaller pilot. I'd put the air screw at about 1 to 1.5 turns out and then put in about a 50 pilot. That may not be just right, but might help get you in the right place. There are several ways to troubleshoot the pilot. One is to figure out whether it cold starts with or without the choke. If it starts cold without the choke, your rich and giving it plenty of fuel to start without needing a choke. If you can't start it hot without the choke, then your lean, because you need the added air/fuel from the choke circuit just to start. If you can get it to idle, pull the choke out after it's warmed up and idling, if it idles better you're lean, if it idles worse you're probably a tad rich. You can also let it idle, if it will even for few seconds, and then kill it and look at the plugs, if it's way rich you'll have a lot of fuel/oil built up on the plug. The air screw simply adjust the amount of air going into the idle circuit to fine tune the air/fuel at idle. If your too rich, the air screw will not make any difference. Does it cold start w/o the choke now? Does it foul out when idling. Well, there's a few things to try and work on. Let us know how it goes or if you have any more problems. Later.

CrashFireBanshee Posted July 8, 2004 Author Report Share Posted July 8, 2004 The idle adjustment is the same as the choke. turn it counterclock wise and it rasies the idle and the choke plunger. it is turned all the way out just like if the choke was on all the time. I try to twist it down and it won't idle. So I am thinking it needs more fuel. I worked my way all the way down to a 38 pilot and it really didn't have much effect. would an air leak cause this?

CrashFireBanshee Posted July 9, 2004 Author Report Share Posted July 9, 2004 My carb boot is all cracked up. I don't know if it is cracked all the way through but I ordered a new one from trinity and all new gaskets. I hope this fixes my problem. I can't honsetly believe that my bike needs that big of a pilot. Does anyone else have any ideas on what the problem could be? Quote Link to comment Share on other sites More sharing options...
