AHHH.
That was my thought too. The front cylinder is the one fouling plugs. But when I just reevaluated the gap and tested spark they both fired ok. Actually, pretty bright blue spark too. The rear had more yellow spark until I opened the gap a to the 35 side instead of 32 and now its firing bright blue.

Replaced parts list
PMS plug
PMS screw kit
Main jet 0.6
Main jet #35
Needle valve set #5UH
Needle set #4wm
Main Jet #165
Manifold

I did not read anywhere that you cleaned the fuel tank, internal petcock filter, external fuel filter and fuel line. If not, that could be an issue. Do you have a fuel pump, or did you remove it?

Yeah I did a clan of the whole system. However I have not done a pump delete. I am considering it, however I want it as close to stock operating right as possible so I know I'm starting with a functional setup before modifying. That way I can be absolutely certain any hickups are in the modification, instead of trying a mod on a motor already not right. I will never know if I screw up a mod or if its a current issue.

The PMS is just for adjusting the air fuel mix at idle. It controls the fuel. If you set it at 2 1/4 turns out from lightly seated, it should be fine. I'd do that, and then not mess with it, until the bike is running well. IMHO, if you set it there, it will be fine forever. That's where the factory sets them.

The proper float level on these bikes, is about 4mm above the bowl to carb mating surface. This is checked by Yamaha, with the carb on the bike. The bike sitting upright(it works best on a bike stand(lift)).
Attach a small clear tube to the bowl drain, and open the bowl drain screw. The fuel will fill the clear tube, to the level in the bowl.
***Now then, the fun part....you want to hold the tube vertical, along the rear(the intake manifold side, not the air cleaner side) edge of the carb. It'll come off the bowl drain, loop around and up along the back(intake manifold side) corner.

Be advised, as long as the petcock is open, the tube is on the bowl drain and the drain screw is open, if you let the open end of the tube get below the fuel level in the bowl, it'll promptly drain the tank, and in the process pee fuel everywhere.

If you get north of between 5 and 6mm, you'll be getting into a possible rich scenario. Over 6, and it may run but you'll foul plugs after a bit. 4mm-ish, should be just fine.

Don't over tighten the bowl drain screw. You can crack the seat area. Snug is good.

Cap the brass nipple on the intake, if you haven't done that yet.

If you haven't noticed already, there is a "Tech Articles" tab above. click on it, and it will have a lot of carb stuff to look at and read, that pertains exclusively to the Roadies.

NO I always do a housekeeping check before reinstalling parts.

Yes. Those are the exact setting that it was at for the last video. I backed down 1/4 turn to 2 PMS after that.....again, and walked away before I kicked the bike over hahahah.

I guess I can try the manifold nipple cap, but I really cant believe that it isn't capable of running right without doing that. I mean it ran when it left the plant with it on. I feel like a DR with a pt that is in pain but cant find a thing wrong. I have to be missing something.

Guess Ill have to suck it up and take it to a shop. And ill kick myself when they hand me a $200 tab for a hose I forgot to attach, or a wire that was loose, or a screw that fell out.

There is a video on you tube that shows everything about a roadstar carb. If you haven't already watched it, check it out. Road star carburetor disassembly

I would take up Shamrock on his offer before I would ever take my bike to a stealer. My 2 cents. Another set of eyes may catch something that you're overlooking.

Re:New owner. Wishing it was better news 5 Months, 3 Weeks ago  
OMG Amateur hour at the Apollo!

So last night it hit me. I have checked my slide and listened for the sweeet sucking sound flipping it with my finger. I NEVER put negative pressure on it to actually watch the slide was smooth. DOH

So late last night I popped the shop vac on the back, it didn't even try to lift. I popped the compressor on the vacuum vent, it went up mayyyyyybe 1/10". Never even crossed my mind that the slide might be bad enough to operate by finger but not by vacuum.

Spent about an hour and a half with 2000 grit cleaning the plastic and the slide port until it slid on vacuum. Threw that sucker on this morning fired up and tipped throttle, vroom vroom vroom. those guys on the clinic are gonna be maaad at meee. lol. It was a pain to clean that thing but yeah, my touted "expertise" in cleaning carbs and I never cleaned that dad gum slide port! just kidding, it was prank, my bike is fine pay no attention over here I didn't actually do something stupiiiiid.....

But seriously thank you for all your input. Ill still be coming around to say hi and to see how to do the mods now that I'm running.
