I got so stuck trying to figure out whats wrong with my scoot that I decided to do a rebuild. got a new 83cc motor coming, but im half sure that my main problem was electrical, so I want to replace the whole wiring harness, along with the cdi.
the few ive been able to find in stock say stuff like "installing yourself is a long and complicated process, consult with your scooter mechanic, etc..." im very mechanical, but never liked working on electrical stuff. Has anyone installed one? on different scoots? if its just following wires and hooking up the plugs I can handle that easy. but i know all scoots are different, and im worried that half the plugs wont be the same, and ill be cutting and splicing wires, probably causing more harm than good.
I would just like to know what im getting into. also if anyone knows where I can get one soon besides ebay that would help (seems like most scooter dealers are out of stock and there is some fool on ebay thinks he can get $140 for one).
Scoot on!

As said before, stock intake/air box, 50mm BBK (83cc), and an ebay exhaust. no cam yet...
also a red hot ignition coil and iridium plug.

ohh sry. you said valve timing. I do not know as I had a shop install the BBK because I knew I wouldn't trust myself with timing

if this is the case than that's great! this is my first scoot but with my cars the intake was always my first on my list. when my scoot was new I went to the local shop and asked for one and they said they don't sell them because if you didn't have a jetted carb and an exhaust, all youll do is burn up your heads, which made sense. So I put on the back of my list.
but it all makes perfect sense now! that perfectly explains why the bigger carb makes it run worse, im starving it of O2 even more.
I need to ride into work tomorrow, ill pull the plug off the front of the airbox to see if that helps for now...
thanks!

I have a stock air box. but your link shows a post about timing and I don't know what to make of that...
How would intake and choke affect timing? Seems to me the only part that would affect timing other than internal engine parts (i.e. timing chain, cam, etc.) would be the cdi...
maybe that's worth looking into...
or I probably am just running to rich or lean, I just couldn't figure out which...

I've been having problems with my scoot idling after it gets warmed up. It wont. It starts and idles fine (probably a little fast even) cold but once hot it will bog down and quit when I come to a stop, so I have to hold the throttle to at least 4-5k rpms to keep it running. I know this is wreaking havoc on my clutch but I have no other option as my starter is not working either, and I cant be getting of and kicking this thing at every red light Im at...
I thought this was a carb issue so I bought a new 23mm carb because I was using a stock carb on a 50mm BBK with aftermarket exhaust (nothing fancy, just an ebay exhaust). I installed it at work today and on the ride home it did not help the problem but now it is cutting itself off while im going down the road and cutting back on a half second later. This can happen 3-6 times in a 15 second period then maybe go a few miles with no problems, maybe not...
Also now when I go to accelerate from a stop it seems to be misfiring or some thing because it will go, quit, go, quit, around 10 times in 4-5 seconds, but then it will go like normal. I have also started noticing black specks of soot on the back of the bike coming from the exhaust. I think all 3 of these problems are related (not idling when hot, misfiring when hot, and the black stuff coming from the exhaust) I still think its carb related, but 2 carbs, same result? Im stumped...
So everyone knows I've tried 2 different ignition coils and my plug (iridium) looked fine last I checked it so Im pretty sure Im getting consistent spark. I also checked the valves and they were spot on. (I reset them for good measure)
All help is appreciated! You guys rock!

If so, which one?
during the 3 mile walk home the other day after my belt snapped again I decided it was time to get a small, cordless impact driver that I can keep with me. I had a belt, with no way to change it in a parking lot. I do most of my work at my shop with an air compressor.
anyways im looking to see if you guys have some experience with certain models. im gonna need something with some b@lls, to make sure it will work when I need it to, but would still like something pretty compact. ive been looking at the Milwaukee 2451-22, nice and small with a 3/8 drive, but lacking with only about 83 ft/lbf. don't know if it would break a variator bolt every time...
what do you guys use?

I bought a AMANET red light changer about 10 months back from the local scooter shop. they said it was the only one the sell because it only one that "actually works pretty good" the guy told me. I installed it and the next time I went out I noticed it immediately tripped the light outside my appt. complex. its a side road that ends at a main road and the light never changes by timer, only when someone is waiting to turn left. I used to have to run it all the time...
I went on down the road thinking this might have been the greatest $25 I had ever spent. but as time went on I encountered more and more lights that it doesn't work on. Maybe 5% of the lights it does work. at one point I was considering getting one or two more to see if it help, but I don't think its worth it.
They can help a little, but its not something that will make a difference in the way you ride.
My biggest peeve is when I pull up as far as I can at an intersection to make room for a car to come up behind me over the sensor, and they want to stop 25ft back...

where did you get that motor and what is it (size wise)? ive been looking for an 83cc (100mm) crate motor with the pressure vent in the head (the little tube thing coming out the valve cover) the one pictured on scrappys doesn't have that, but might be an outdated picture...

That 1P39QMB might be a "secret 60". don't know much about the taotaos but from what ive been able to conclude is that the P means it either has the long 69mm valves or has a 44mm bore kit, like my first engine did. So maybe a slightly larger jet would work, but im no expert on carbs...
And my scoot LOVES the humidity! always runs about 5mph faster when I take it out after a rain storm.

These guys make very nice paint for your average non-professional. I learned about them because my dad kept bringing me parts to paint for his ducatis. He wanted to bring me his own paint instead of using mine. i was very surprised by the quality. www.colorrite.com/I have only used their spray can paint, but they sell it to where you can put it in your own spray gun. they use a 2 stage system (base coat / and a clear coat) which makes a big difference (the ultimate difference if you're painting anything with metallics or pearls) and with the right prep work and clean painting conditions, you can achieve professional results. (buy a tack rag and some wax and grease remover) If you want the real stuff, spies hecker makes the best paint there is, imho. standox is good too, same company. if you have any carquests in your area they should be able get you some Sherwin Williams which is pretty good also. ideally you would want a 2 stage (base/clear) with a 2k clear (2k= 2 component , meaning you mix the clear with a hardener, kinda like bondo, making it a lot stronger, scratch and chip resistant, better UV protection, less fading, higher gloss for years to come, etc.) you cant get 2k clears in a spray can, obviously, with the hardener in it, it would dry up in the can. color rite does sell a 2k clear but I cannot vouch for it as I have never used it, but I will say that I never believed the was such a thing as a good 1k clear till I used their stuff... most "rattle can" clears either dull out or milk up after 6 months. some of the parts ive painted with their stuff is 6 years old and looks like it was painted last week. if youre gonna go with a single stage, i.e. not a color/clear system but the color coat dries "shiney", do stay away from metallic or pearls. single stages should need a hardener anyways so youre not saving that cost, and the metallics don't mix well with the part of the paint that makes it "shiney" your paint job will be dull/flat/no shine at all in less than a year... either way, real paint will cost you real money, and if it isn't prepped right or applied right it wont matter what you put on it. Ive been in the paint/auto body business for 16 years now (more than half my life) and for ease of use, quality, and price, color rite wins for a DIYer. let me know if I can help more, im on here so much asking other people questions, I love when someone asks about my area of expertise... Good Luck!

im using the factory tach. are they known for being off? I know the odometer is... if so are aftermarket ones hard to install? it came factory with 8.5g rollers. gonna swing by the scooter shop this week, they say they have 7 and 8g sliders in stock. Ive already ordered the 23mm carb and red ignition coil from scrappys as well as an exhaust... cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=151068189621hope it makes it run alittle better. should I worry about what the new carb is jetted to or should it be good to go?

Ive checked out some posts on here about gaining power (especially going up hill) where people complain about their scoot bogging down to 6 or 7k rpms, which stuns me...
My scoot, at WOT on a flat surface does not like to go above 4500 rpms. the engine seems to like damp, cool conditions so if I take it out after a rain storm it might run at 5k rpms. under normal conditions though I cant get it above 5k unless im doing going down a nice long hill. I think the highest ive ever gotten it was a little over 6k.
I can tell when its letting the rpms go up, im getting a lot more power when I need it, so id like to know how to let it get up to maximum rpms.
ive looked into CDIs but cant get a clear answer on exactly what they do. half the people say they adjust the timing and the other half say the remove the rpm limiter so it can go above 8k (if I cant get to 7k, why would I need it?)
im on my second engine (stock was a 60cc, now it has a 83cc) and both behave the same way...
any help is appreciated!!!
