hey I had a simular problem. i ended up doing a rebuilt kit and it fixed the issues. reason is those parts wear out.e ven though ti says 112 jet it coudl be hogged out to a 118 jet due to normal use. also the needle will thin out over the years and the mixtre screw will thin and scar like yours.
personally I think getting a $20 rebuild kit and repalcing everythgin woudl propbebly resovle the issue. it jsut really looks like the parts are slightly worn out but under normal conditions which makes it ahrder to detect than something that was sitting for years.

Hey Oscarmayer...........I know the #35 jet is opened up cause I did it with a drill bit when trying to unblock it. Waaaaaay too big. That's the reason for replacing that one. I'm trying a smaller one on the main because "I think" Honda, at the factory, purposely jets their trikes and bikes a little rich to protect themselves from lean damage. The Uni filter I put on should lean it out a little, too. I replaced the o-ring on the pilot screw. It was squished and a little tore at an edge. All the passageways are clear in the carb. Slide looks good. Needle looks good. I checked everything under magnification. The trike ran pretty good from 3/4 to full throttle, maybe 1/2 to full throttle. Ran like crap at 1/8 throttle just putting around in first gear. Idle was off and plugs were loading up bad just idling. Black as coal. They were black too even when doing WOT chops at full throttle in 5th gear, just one run up the alley with brand new plugs. I did three chops like that and that's why I figured I could go down a little on the main. I just want to see if I can optimize the performance for this stocky. I would have put a rebuild kit to it, but I don't personally think it needs one. If what I'm doing doesn't solve the problem, you can be sure that a rebuild kit is next on the agenda.

Went and picked up the stock #35 slow speed jet today that finally came in. I just got in the house. It's 11:30pm here, EST in Ohio. Installed the #35 slow speed jet, installed a #110 main jet (#112 is stock). Put it all back together WITH the new Uni filter and the air box cover. Adjusted the pilot screw 1 1/2 turns out from lightly seated position. Installed a fuel filter in between petcock and carb. Turned the petcock 90 degrees so that the adjustment lever faced towards the BACK of the trike and the petcock barb faced the exhaust on the right side. Looped the fuel line around and brought it around the backside of the slide chamber on the carb and to the barb on the carb. Not sure if that's the right way, but it seems ok.

Got it started with choke on. Had to mess with the idle adjustment some. Waited a couple and turned the choke off. Gave it quick shots of gas at the throttle and it hesitated BAD before revving up. Did it a few times, no difference. Messed with the pilot screw OUT MORE and still had the hesitation. No more smoke, though. Went in on the pilot and must have went too far because then after revving and letting off, it came down from the high rpm's real slow. I kept adjusting and finally noticed that the exhaust was CHERRY RED coming out of the motor. Turned it off QUICK!

Took everything back off and put the stock #112 main back in. Put it all back together, set the pilot at 1 1/2 turns OUT again and fired it up. Idled real high. So, I backed off the idle screw, MORE THAN I HAVE EVER BEEN ABLE TO BEFORE, to get the idle down. Gave it quick throttle bursts and it still had the hesitation before revving up. I went out on the pilot screw another 1/2 turn and checked it again with quick throttle bursts. It seemed better, but still hesitated before revving. But after revving and me letting of the throttle it came down quicker. I opened up the pilot another 1/2 turn and checked again and was better still. Slight hesitation, but came down pretty quick. Went almost another 1/2 turn, and checked again and it seems good. A little hesitation just revving it in neutral. Decided to take it out for a spin up the alley.

In first gear, popping the throttle hard, NO hesitation. I checked and checked again. No hesitation. And no more "rough running" just putting around at idle in first gear. I nailed it through 5 gears up and down the alley and it responded well. No backfiring. Sounds REAL good. Fast! Comes down fast from high R's.

Brought back to the garage and in NEUTRAL and throttling fast and hard, still the "slightest" bit of hesitation. But NONE when hitting the throttle in 1st gear.

I'm about 3 turns open from the seated position on the pilot. I know that's more than the SM says, but at 1 1/2 turns open, it hesitates bad. I think I'm going to go another 1/4 turn open tomorrow and see if I can eliminate the hesitation in neutral. No smoke at all anymore. That was all from the drilled out slow speed jet it seems. It's running like it's supposed to. At least I think so. Idles super smooth. Nice and even with no misses or ups and downs. No indication it wants to stall. I didn't set with a tach. Just by ear.

Things seem good. Stock jet sizes. A new O-ring and washer on the pilot screw. New air filter and fuel filter. The biggest thing I noticed is that the adjustment mechanisms..............the pilot screw and the idle screw............actually do something now and moving either of them just a little does something. Didn't have that before. I had the idle screw almost all the way in before to make it idle. Now I'm almost all the way out. And before changing the drilled out jet, I could completely screw the pilot all the way in and the trike ran. Actually it had to be in almost all the way with the drilled out jet to make it run. Now it's out 3 turns and screwing it in too far makes it lean and turns the exhaust cherry red. What a difference a jet makes, huh?

Thanks for the update, good to hear it.

Eric..............Do you think that by installing a larger slow jet, say a #38, instead of the #35, that it could help get rid of the "super small hesitation" when throttling hard? I have a #38 jet. With the less restrictive UNI air filter on the trike now, would it be able to handle the larger jet? Would that maybe allow me to back off the pilot screw some, more in line with the 1 1/2 to 2 turns out position, instead of the 3 turns out now? What are your thoughts?

Sounds like a bigger pilot would be the way to go. Did you move the needle at all? Richening the needle/raising the clip should help with the hesitation when throttling In.

Hey Jason.......I put the clip back to where it was at the middle groove (stock). Maybe it's just the UNI filter causing it to run a little lean? I'll probably try either moving the needle clip or throwing the #38 slow jet in and then closing off the pilot screw maybe a turn or so. Having too many deaths in the family lately, 3 in the past couple months, so I have funeral this week. Plus I've been working on the Harley some. We'll get to it, though.

And I don't know if I already said it, but GREAT BIG THANKS TO EVERYONE who helped me with knowledge, advice, suggestions, and lessons. It helped me a LOT! Couldn't have done it without everyone's help. I don't know what I'm going to do with the trike yet. Don't get me wrong, I love my trike and tearing up the trails around my area. But I like working on them, too. I "may" want to get another one that needs some work and fix it up. Just don't know yet. Have to find a deal first. I'm really not into the full resto work. I could do it, but really can't see the point. Full restorations really look great, but if something looks that good, I wouldn't even want to ride it. And what fun is that? Just give me a pretty clean, decent looking, well running trike that I don't feel guilty about riding and running hard and that's best for me. Museum pieces may be fun to build, but after they're built, it's pretty much over. Just my 2 cents. Think I'd like to do a 110...still have a soft spot for them and like the bounce.

I'll let you know how the #38 jet does and/or the needle clip move.
