Seems like a awful big jet size for your app. You sure you dont have an air leak?

The only 2 places it could possibly be leaking are the intake gaskets, or the top of the carb where my cable adapter is. I may spend the day using some copper spray on the intake gasket and see what happens. I didn't think 100+ was that bad for a UNI filter though, is it?

[drawkward]

Have you performed any sort of a leak test? Its probably got one somewhere... curious to see how the custom jets work out.

[lshigham]

I wouldn't say 100+ is unreasonable with a UNI, I've had to use a 115 with my 17.5mm before

It depends i guess..On allot really. Im running a 95 and a little rich

So I spent this morning outside throwing in carbon fiber reeds, a boost bottle, and making a adjuster for my air screw. The carbon fiber reeds made it stutter even more at WOT, so I made the adjuster to see if it helped. I just took an old junk allen wrench and threw it on the grider. Here's the results:




You can see the screw to the right of the word "INC."

This one is sort of hard to see, but it's the same shot, with the adjuster in there from the bottom


With this adjuster, I have 180 degrees of movement, at which point I can start over again for the full 360 degrees I need. After unscrewing it 1.5 turns out from where it was originally, I have no stuttering or lag at WOT. Though I do still have my old issue with bog on the low end after the engine warms up. That's what my packs of idle and main jets are for though ;D Oh, and the boost bottle added some quick throttle response as well. After throwing that on, I can twist the throttle and the back wheel instantly moves when it's on the stand. No more spin up time!

Quick question. Is there any way to use a degree wheel without having the head off of the cylinder? I'd like to check my timing, but I don't want to have to buy yet another gasket set.

Yep,The "dead stop method" works well with the head installed,just need to fab up something to go thru the plug hole to stop the piston before it reaches TDC.I gut an old plug,weld a nut on the out side and screw a long bolt through..

Sweet. I may have to spend the day making one of those then! After reading about timing issues on scooters, I figured maybe that's my issue with the bad knocking that comes from under my butt at WOT. I switched to premium gas and it still didn't fix it.

Well, at this point I think I'm better off to just buy a tool for that. I took an old spark plug and tried gutting it out. I got it 3/4 gutted, but the last piece of ceramic doesn't want to come out. I've tried hammering it out, drilling it out, everything I can think of. It just will not break no matter what I try. I've been working on it for 2 hours!

Yesterday I tuned it up, sealed up the intake, and it was running it's best EVER. Today, I go to start it up and it wont run for shit. I checked the plug and it was wet. I downjetted 6 times, both the idle and main jets, still wont run. I went from a 104 to a 85, and everything in between, and nothing changes it. It's almost like it's purposely TRYING to piss me off! Not only that, but I kicked the starter so many times that it ripped a hole in the bottom of my shoe. Now I need a new pair of shoes on top of it!

Yet another update. I went outside to see if I could get it running today, seeing it was a beautiful day earlier. Kicked it and it started right up. I hit the gas and it bogged. So I knew it was too lean with a 85 jet. I thought "Well, lets see how much of a bitch this thing really is" and threw the exact same setup that I had in it when it wouldnt start at all the other day. 104 main, 30 idle. Threw those in, kicked it, and it fired right up, no bog. So here I am wondering what in the HELL was the issue the other day? A side note though, when I went to adjust the idle, it died and wouldnt start again for about 2 minutes. Not sure why this thing is being so stubborn lately.

I eventually got it running and went for a few test rides. Still needs tuning, but it's getting there (if it'll stay running) I'm betting the no-start issue is a problem with the carbon fiber reeds. It's the same symptoms I had last time I tried them. But it boggles my mind, because they were working beautifully, until I sealed up the intake gaskets with copper spray. I was hesitant in sealing it up, specifically because I had an issue with these reeds last time I sealed it up. It's like they don't work right unless theres an air leak

Sounds like you need to ditch the reeds for now. Maybe see if they are sealing against the reed cage when you pull them out.

I feel for you on the weird tuning issues. Been having the same stuff lately where a perfectly good tune is out of whack all of the sudden. It's frustrating, but keep at it. Take plenty of breaks when you get really tired of it.

I've learned to take breaks The other day, I absolutely HAD to take a break for the whole day. After the kick starter ripped a hole in the bottom of my shoe, I was about ready to pick up the whole scooter and throw it out into the street while a semi drove by. Makes me happy to know that eventually it'll be sold and I won't have to deal with the issues anymore ;D

I know those feelings. I've watched friends sorta act on 'em. Seen them get mad and just push a bike or scoot and let it all over and sit there for a bit. lol Actually, one night years ago, a friend's little midbike broke down on a ride. He smashed his helmet into it and then busted his helmet on he asphalt throwing a fit. By the time I got back with the truck it was all screwed up. He ended up breaking every body panel on the thing. A good show, but that's why you gotta take breaks. lol

Oh wow It took a lot for me to just roll it back in the garage the other day. I was pissed

Oh, another thing I noticed. The threads in the frontmost hole for the intake bolts are nearly completely stripped. when the engine was cast, something got screwed up and there wasnt enough material in that area when they tapped the holes. It really only ever had threads on one half of the hole, the other half is too large and untapped. When I sealed up the intake the other day, the bolt almost gave way when I tightened it down.
