this was yesterday. had a old pj38 sitting in the garage so i threw it on just so i could give the bike a shakedown. didnt run that great as you can hear but really i didnt care because i was gonna put the lectron on today. only mechanical issue was the fuel valve was leaking alittle around the bolts but i put more sealer so i hope that fixes it. thnx to rsss as he gave me some pointers along the way and neels van niekirk helped me quit a bit also. alot of this engine was designed using neels program.

yeah thosedirt bikes are hurting for space for any extras.
couple things that stand out just looking at the pics.
the pulse line from the motor to the pump may need to be the reinforced type especially with the added distance I use standard renforced black fuel linefrom the autoparts store
I would not run a fuel filter, the screen in the tank will be enough, filter hurt flow and the with a lectron ther is not really any small orfices that can get plugged from small dirt that may pass threw a screen in the tank

i changed out the clear one for 1/4x1/2 fuel hose. i think its reinforced. had some white fiber stuff in the middle. should be good now

what do you know about spraying nos on a alky motor ? just remembered this ign has 12v 130w which should be enough to power a small electric pump for a wet kit. mount a 2lb bottle on the front number plate . intake manifold is alluminum so i could tap in there for the nozzles. :smoking

anyone got some advice for what they see from the pics and vids ? the plugs had multiple passes so maybe theyre not of much value. with both PJ open it wouldnt clean out so i kept the same plug and kept closing 1 PJ until it started to run better. seems like its in 3 turns now. runs alot better than it did at first. also im thinking the needle might be lean ? seems to zing quit a bit when you rev it up and let off. kind of looks like all the plating might be burned off but then again i did alot of runs one after another so maybe that had somethin to do with it. also there isnt much smoke

the plug in the second picture shows heat in the motor and would not lean it anymore.
I would adjust the needle at least a 1/2 to 1 full turn in and go from there, sometimes when they are new you need a little cresent wrench to turn the needle because it being so tight.( make sure you are slightly pulling down on the needle while doing this)
If you do a half turn you have to push up and adjust the needle position so the flat side faces the reeds.
Pushing up and turning the needle is NOT adjusting the needle length this only changes the position

heres where im at now. saturday went and tuned more by my house. turned the needle one turn richer and it sounded alittle better. one more turn it sounded even better. one more turned sounded better. so its 3 turns richer than the original 53mm length. sounded pretty good and didnt have that lean zingy sound. put the PJ all the way open then 2 turns in. you could take off full throttle and it would sound like a blubber sound for about 2sec then go like a raped ape. so i leave the carb like that and drive to the dunes 1,500' lower elev and about the same temp. now the damn thing wont run worth a crap in 2 or 3rd gears but went you hit 4 and 5th it goes like a raped ape again. 2 and 3rd gears sounds like a gas bike with main jet 10sizes to big. turning the PJ in made no difference. since i was testing on a dirt tire and switched to a paddle maybe that put a different load on the engine making it pull different amount of fuel ? this engine is confusing the hell out of me. like i said i had it working good at my house then at the dunes 2 and 3rd sounded real boggy and wouldnt go more than 15mph full throttle then hit 4 and 5th and it went like a raped ape.

needle sound to rich , paddles put allotmore load on the bike just keep adjusting the needle until it cleans up

udontknowme · « **Reply #69 on:** September 02, 2013, 09:41:08 PM »

probly the needle but i dont see how it could of went rich with the drop of elevation unless the tire had something to do with it. got some dunes around here to test it next time instead of dirt with knobby tire. swingarm extensions are next on the list. kept trying to flip over with the paddle
