glamisaurus Posted February 11, 2006 Report Posted February 11, 2006 I have a 400 T-Rex with dual 35 PWKs. The bike will start no choke right off the trailer at Glamis with one kick but takes a few kicks when warm. It has a 45 pilot jet in it. Leaning it out with the air screw doesn't seem to do much. I did a search and it sounds like the pilot is rich. Does a 45 pilot sound big for my setup? Quote
glamisaurus Posted February 11, 2006 Author Report Posted February 11, 2006 (edited) Not sure which needle thay have in them. I thought that the needle doesn't come into play until you open the throttle. I'll open them up this weekend to check anyway. Edited February 11, 2006 by glamisaurus Quote
wesw Posted February 11, 2006 Report Posted February 11, 2006 yeah the needle effects a lot. length and diameter, taper many factors Quote
glamisaurus Posted February 11, 2006 Author Report Posted February 11, 2006 CGK with the clip on the fourth groove down from the top. Quote
wesw Posted February 12, 2006 Report Posted February 12, 2006 hmm thats a needle thats kinda lean down low anways with the g series length. most need a 50+ pilot. kinda wierd. Quote
glamisaurus Posted February 12, 2006 Author Report Posted February 12, 2006 I put some 40 pilots in it and the throttle response seems like it might be a little snappier. It still fired cold no choke on the second kick. It runs great otherwise. I just thought it was kind of odd that it would start so easy without the choke when cold. Quote
trex banshee Posted February 15, 2006 Report Posted February 15, 2006 mine was always kinda weird when starting when i had it on gas. It didn't matter how cold it was i had to never use the choke, but when it was warm it would still start on the first kick. I ran 145 mains and 42 pilots at nearly 1000 ft elevation. and i had the needle in the middle position. Quote
glamisaurus Posted February 16, 2006 Author Report Posted February 16, 2006 At least I know I'm not the only one. It was 40 degrees one night when we pulled in to Glamis and the thing fired right up. Usually it will idle high for a couple of seconds then settle down a little. I moved the needle to the middle yesterday and now it stays at the high idle with the 40 pilots. Quote
wesw Posted February 16, 2006 Report Posted February 16, 2006 sounds like you leaned it out. you might put some 50 pilots in and see how it acts Quote
trex banshee Posted February 16, 2006 Report Posted February 16, 2006 must be the nature of the cylinders if they are stock for the trex(68mm) and port. mine would idle high for about 2 mins then calm down and idle perfect all day long and never load up and the plugs where always a nice dark. (i like being on the safe side.) Quote
glamisaurus Posted February 16, 2006 Author Report Posted February 16, 2006 The plugs look good. I think I will take it out and run it hard before I make anymore changes. Thanks for the help. Quote
BansheeGuy_IV Posted February 16, 2006 Report Posted February 16, 2006 Hiya... CGK... For your setup, and from what you describe, the K in the CGK is a little rich. If you go to a CGL needle, I think you'll be presently surprised. Your Pilot jet is in the ballpark. Give the CGL's a try. You'll be glad you did. BG Quote
Polish Posted February 16, 2006 Report Posted February 16, 2006 Contact John at Alba in the R+D dept............he has the specs for that motor..........and the correct jetting needed (858) 486-4380 Quote
glamisaurus Posted February 19, 2006 Author Report Posted February 19, 2006 The T-Rex ad on Alba's site suggests EEK needles and 42 pilots. LRD did some work on my cylinders so the jetting would probably be a little different than an untouched set. It ran good this weekend out in the dunes. It does not pull very high in the rpm but the low/midrange is very strong. What do you think of LRD pipes? Quote
