2 into 1 jetting

[sheerider1026]

have a trinity 2 into 1.. has a 34mm pwk.. has a 155 main and a 48 pilot airscrew 2 turns out.. the needle is a dej.. it runs fine but the 1/4 throttle response is a but sluggish.. i raised the needle one clip.. any idea where my needle should be??

they didn't make a 34mm pwk. so is it a 34mm pj, or a 35mm pwk? Is 1/4 throttle sluggish as in rich, or hesitant as in lean?

its a pwk so it must be a 35.. not sure on the throttle if its lean or rich.. i am leaning towards it being lean since i raised hte needle clip.. i am also going to order a dek and a eek needle tomorrow for it.. i have heard that the dek is the better needle to run.. do u think i should play with the needle clip?

the needle controls almost everything on those 2 into 1 setups. Off hand it looks like your running the wrong needle, too small of a main jet, and a slightly too large pilot jet. However, you did not post what was done to the bike and where it is riffen.

i was wrong on the pilot.. it is a 35.. do u think i should get a eek or a dek needle?? i have heard that the eek is the best for this setup.. i do have mains up to 180 to try.. what do u think on the pilot and needle?

whats done to the bike, and why type of riding do you do?

[sheerider1026]

stock port, t5's 19cc domes +5 timing, ram valve reeds, K&N, trail riding, open fields, occasional race.

start at 185 main and work your way down for best topend result. Usually I start with an eek or eej needle in middle positon and adjust accordingly. 45 pilot jet and air screw 1.5-2 turns out. If you run a dek and you have a lean hesitation on the bottom end than try a dej needle. if its too rich on the bottom then you go to a del.

hey thanx for the info.. it currently has a dej needle.. i ordered a dek and a eek from carbparts.com this morning... i have heard that the eek is the best to go with and tune from there.. whats your opinion on the eek?

It works well in most motors that turn 9500-10,500 rpm. I have one in my friend stroker with ptr mids. I think I currently have a eej in my bike.

right now i have a 35 pilot, dej needle, and a 155 main.. seems like it would be lean as hell but its not.. any clue?? can the needle cause this?? i have a set of 33mm pwks on my cub motor and i run a 148 main, it runs sweet, plugs read perfect on it also..

its probably mostly running off the needle. Take it out, warm it up (ride around a little), and then run it full blast wot for two passes in 5th gear. Then on the 2nd pass shut it off after 4 sec's wot in 5th gear. Pull in the clutch and coast to a stop and pull the left plug and see what the color is. I was running like a 190-195 main for a while and the plugs kept coming out whitish. I figured out the fuel was washing down the plug. I went to a 185 and it started to turn dark brown finally.
