Was there a restrictor in the Pipe?

Nope, have not taken it apart to see if there was one elsewhere but I don't think there is. It's just a tiny pipe is all.

Also, edited my post to say "red" torque spring instead of blue. I want stiffer, not less stiff, lol.

Very few setups require a red torque spring. They're good for racing and not much else.

Cool, well I guess I will keep testing and see what happens. I also read that if you switch to sliders that you need 1 to 1.5g heavier weight than what ever roller you tuned with so maybe it will all work out.
Also the next time I open up the clutch I will probably do the ball-bearing thing under the contra spring too.
Didn't get a chance to test more with the 3x6g weights in there this weekend, but I had better hurry- not too many good riding days left this year probably.

So I was getting confident enough with the scooter to ride it to work on Thursday, but unfortunately I didn't quite make it.  I also discovered that the fuel gauge is not entirely accurate, haha. Thankfully I was only about a block away from work and it was easy enough to walk it the rest of the way, and later that day a co-worker was able to run me home to pick up some fuel. I have also been experiencing some pretty strange starting issues that maybe you all can help me with. 90 percent of the time, it will fire on the first kick. The remaining 10 percent usually 3 or 4 kicks later. Where the problem lies, is during that time when it fires first kick, 3/4 of the time it will sputter out in 2 seconds or so, and then it basically takes either a miracle or a shot of carburetor cleaner to get it going again. As in, it won't sputter, won't kick a couple times then die again, it just plain does NOTHING. Does not seem to matter if it is warm or cold, although most of the time when it happens it is cold. I have tried to anticipate it, experimenting with pulling the choke, cracking the throttle, etc.. but nothing makes any difference. I have pulled the plug during these times (after 20 or 30 attempts with no starting) and it never appears to be wet or flooded. If I hook up my jump starter to it, I can thumb the starter for about 20 seconds and it will usually slowly build RPM and eventually start and after that it is fine. Until I get a new battery for it, kick is the only way I can start it and with this issue currently, it seems like a good way to get stranded somewhere. Also I think the frame might be bent slightly. It might be my imagination, but it seems like with my weight on the seat and on flat ground, the bars want to turn to the left. While riding I usually need more pressure on the left bar to keep it straight. There is also some play in the front steering stem so it also might have a bearing issue. The more I ride this thing the more I want to fix these little issues, lol. The starting thing is a major problem though, I hope I can get that sorted asap. Thanks, Brendan |

What carb are you running?
What's your current jetting?

It aint getting fuel at start if a shot of carb clean lights it off..Enricher(Choke) circuit lean/clogged possibly..

Try kicking it and DON'T crack the throttle. With the slide/needle in the down position you make more vacuum to pull in more fuel. Works great (usually) when a bike has sat for a while and the fuel in the carb has evaporated.
Like 190 said, it could also be your enricher. Another thing is if it hangs when coming off throttle, then you would need a larger pilot, which can also help with starting issues.

I wonder how the enricher circuit could be clogged up with like, maybe 5 hours on the build? Anything is possible at this point, lol. Thanks for the tips, although it must have known I was bitching about it online, started it about 4 different times yesterday and each time it started first or 2nd kick, haha. Doesn't seem to be hanging off throttle anymore either, so I think the pilot is sized good enough to rule that out. I'll keep monitoring it and see what it does. I loathe the idea of removing the carb to clean it even though I probably have pulled it 45 times since I first fired it up. I just have all the bodywork on it now so it's not a 5 minute job anymore, lol. Thanks guys, Brendan |

Are you running an open filter or stock airbox?

That koso variator wants verry light rolers to go into RPM,for mee it works best with yelow malossi kontra spring on 50/70cc mild cylinders.

Are you running an open filter or stock airbox? Stock airbox with snorkel removed. Also have various holes drilled in the back side and leading edge of the box for testing purposes. Right now they are all taped closed except for two 1/2" holes in the leading side of the airbox which cleaned up the low-rpm 1/4 throttle bogging that I had going on with all the airbox holes taped up. Right now it breaks up a little at higher rpm mid/full throttle positions sometimes, I think it's still a little rich. Brendan |

Yeah I guess so, I went down again to x3 6g weights, 18g total, it's pretty quick now, and actually I only need 1/2 throttle most of the time to keep up with normal traffic. Hit 50 mph a couple times but it starts breaking up at high rpm and I don't want to blow anything up trying to push it harder. I also don't know how many RPM's it's turning at that speed but it seems way up there. Looks like 4g sliders is what I will probably need. Brendan |
