Hello All,
I've been out of commission with oral surgery and horrible KY weather (literally tornado weather, snowstorms and 60 degree sunshine in 5 days). Finally the weather is clearing up and I can get back to working on my bike.
I think my CDI is going bad. My bike acted up a while ago and I let it sit for about a month and now it is running fine again. When my CDI went bad before it did the same thing. Found a performance cdi on ebay for 19.95 with free s/h from a shop recommended on here previously. I can just buy this thing and plug it up or are there any adjustments I need to make to my bike for it?
Also it is time for new front brake pads. Since I plan to add upgrades, what type of brakes should I be looking into. I use my bike for regular commuting and would like to be able to go around 60-65ish.
I took apart the instrument panel to replace the oil light bulb and this is what I discovered
(http://i42.tinypic.com/vziyxi.jpg)
The oil light is attached to the wires ??? How do I replace this? Do I have to replace the entire instrument panel? The manual only says replace the bulb.
Last question (for now ;D), now my tail light is out. The manual says I need 3 bulbs, but I think that is for the euro lighting. I know I need a double filament bulb, but I don't know what type of bulb to get.

Hello there, welcome back. ;)
No adjustments should be necessary with the cdi. They do make "adjustable" ones but i havent messed with those.
AS far as the brake pads, I still use oem spec pads, nothing special.
Speed can be gotten but it's going to take some work.. :D ;)
Wow, i havent even checked my oil light. If that's it, it could have a short in the wire somewhere.????
That light don't normally go out on these things. I ASSUME the oil tank is empty as to how you know it's not working? Of course it should come on when the switch is on for a second though.. HMM, maybe another willl chime on that.. ??? :-\
The tail light has 2 1157 bulbs for the tail/brake lights.. The 3rd one may be the "tag light". There is only 2 tail/brake bulbs....(1157 dual filament) ;)
-
Not sure where you can get the bulb. I looked a little. You just need any 12v led buld similar in size and with wires already attached. Then just cut the old one and splice the new one in. zombie might know where to get one.
You can test it if you haven't already. Just use a multimeter set on ohms to test continuity.
You could always throw a kit on it, run premix, and get rid of that oil tank all together :D :) :)
-
Thank for the info guys. However I've got bad news. I bought new tail and brake lights (cuz one of my brake light went out too) and replaced them and I've still got no tail light or back brake light. There has to be a short somewhere and I'm not very electrically inclined. It's depressing and motivating at the same time.
-
Do the other lights work?
Just the tail/brake?
One thing that worked for me was to "spray" a little bit of WD-40 in the socket, bulb base or hit up the parts store for some "Dielectric Grease". Either will help ensure a good connection.
I can relate, i hate the electrical part. :D ;)
-
I have no tail light at all and the back brake light will not work 90% of the time. I did get it for work for a bit and then it stopped working again. The front brake light works, but I have to pull the handle really hard for it to light.
-
Could be a loose connection in there if it works intermitantly.
The front should have a "brake switch" but you should only need to touch it for the light to come on.
A ground issue or the brake switch. Sometimes wires will become loose as well. MAybe just the plug has loosened enough to give you a head ache?
Just like my ENG-111 instucter says......."breathe"..... ;)
Either the front or the back, the wires are pretty much in sync with each other. That's gotta be a simple fix, just finding it before the hair is pulled out is the thing
-
That tiny oil light is an led. It wont be bad. The trouble is all on the =12v side so you have a bad power or ground somewhere. Since you have to pull the brake really hard I think the hose moves enough to push a connector together. Start by looking under the front cowl. Unplug. clean, and re connect it all.
-
Well said.. ;)
-
I got the bike apart in my living room and an reading the manual as much as possible (mainly to figure out what I'm looking at). I've checked all the wires in the back and they all look fine. It's hard checking the one's in the front, because they're all wrapped up and I have to cut all that off to see them. I do that tomorrow. I went ahead and ordered a voltage regulator (just waiting to receive it), hopefully that will help also. I also take it outside and give it a nice scrub down. Will have more info tomorrow once I get started.
-
Please do!
-
Eureka!! I've found the problem for the brake light. There is a short in one of the wires going to the battery. Still no tailight, but I think the bulb I have is bad. Gonna buy a new one tomorrow and see if it works.

If you look closely there is a break in the yellow wire and also in the blue wire near the top left corner. One of these is the culprit, because once I play around with them my brake light worked fine.
-
Hell Yeah, Great find there...
That will sure cause it.. ;)
(that's a big pic too.. :D)
-
I use this website (http://tinypic.com (http://tinypic.com)), when I post pics, cuz it will size the pic specifically for a message board/forum. However it made the pics really big.
Got a new bulbs and I have a taillight again. Woot! But I think re-wrapping all these wires it gonna take longer than it did to find the problem.
-
Woot!
You'all aint from around here are ya! Congrats on the stick to it ness. It ALWAYS feels good to find the problem...
-
I just went out in the yard and yelled WOOT! People started shooting...

:D You sure you don't live in NC?
-
Almost the same as back woods NC here. I call it "the land that everyone forgot"
-
HAHAHAHA! ;D Nope I'm in KY, but nobody knows it cuz I have no accent (even the natives). All that's left electrically is the cdi, oil light and tail light. Got the bulbs on order and need to order the cdi.
Next mini project will be the oil tank/carb. Gotta leak somewhere cuz the oil tank, fuel filter and oil pump are covered in soot.
. . .and GO CATS! The town's gonna be burned down by tom. morning, guess it's a good thing my scooter in inside tonight!

I'm in Lexington, KY and our college team beat our biggest rival to head into the ncaa championship game. Since we are in a college town, after a big win everyone floods the street and outrageousness insues. Here are some examples, so you can understand the craziness going on last night.

And this is done by kids in SCHOOL!
AXY!!! Any openings in the caves for one more. Americans are paying for their BEST/SMARTEST kids to burn furniture. W the f***!

>:( arrrgggg. I put my bike back together, took it outside and started it up and light came on and went back out. I'm gonna check my battery and make sure it is charging properly and check the stator. I've already replace the voltage regulator. So I know that's not the problem. If those are fine then I going to replace the 2 wires in the pic and see if that helps.
-
That's where this started... Good luck
-
nice pic :). I feel stupid, I forgot that the bulbs are dual filament and put the old ones back in instead of the new ones ::). So the taillight filament was also blown in both bulbs. Once I replaced the bulbs, the taillight came right back on, but still no brake light. Discovered there is a short at the brake switch in the connector, once I bent them a certain way the front brake came back on.
However the lights will dim as I ride, almost to the point that you can't see the brake/tail lights. I tested the battery and the reading were good, so I think it might be the stator. Still gonna do all the things I mentioned in the previous post and test the stator.
-
Your head lights will dim at idle, and slightly above that. It is normal. Your taillights are powered by the battery. If the Batt. is weak it will allow the lights to dim. Also a bad ground will act the same. The lights may work but are using the resistance thru each other to make a False circuit. Try splicing a New ground into the circuit near the bulbs. Just ground a new wire to a bolt back there to see if they light up better.
With the scoot running(/reved up a bit) you should see at Least 13v at the battery. If not you have a problem between the stator/rectifier/battery.
-
They were dimming as I was riding. I discovered one of your (Zombie's) replies on a different post that said not to go above 35 watts for the HL or it can kill ur stator . . . . so I immediately went and took out the 45 watt HL bulb I had in there. Lights came back on at normal brightness, however now the bike will not start. :'(. It'll crank, but won't turn over. Back to the basics. Gonna replace spark plug, charge battery, however I'm scared that I've ruined the stator and will need a new one.
-
Sounds like MY life. The lights, and Ignition are on separate coils within the stator. One should not affect the other. Like you already know... Basics first. Check the ground on the coil (green wire), and you can use a test light to see if the stator is firing the coil. Put it on the black /yellow lead on the coil, and crank the scoot. You should see a very dim lighting of the light. This is an AC wire so it will be dim.
Wire troubleshooting is a royal pain. Hopefully it is a new plug to get you running.
