Today I swapped the key unit even though I found out that it was not necessary. I thought that the stock key unit was broken because I couldn't push the key in and turn left to lock in the front. On a Jog you push in the key and while keep pushing you turn left to lock the front. With the Prebug this goes a bit different. You push the key unit once in and then let it come back up and then you turn left. You don't push it in and keep pushing and turn left that doesn't work. I also installed the side stand, finally, and also swapped the regulator. The speed cable was not an exact fit, somehow I couldn't plug that end inside the drum brake unit. So I just simply used the new speed cable inner wire in combination with the old, stock outer cover/tube. Now I can finally see how fast I am going. Now there is something I am a bit confused and hope someone can shed some light. I have a first generation Prebug (single seat, 3AA). I guess that is a CW50? I found a service manual and some of the specs in there are not the same as on my scoot. For example the spark plug, manual says BR8HS and in my scoot was a BPR6HS. Another example is the CVT belt, manual says 15mm width I got 16.5mm width. The belt is genuine Yamah and has a 3AA stamped on it. Could it be that because the wrong bulbs are installed the turn flash lights act weird? Here again the manual say the following: Headlight 12V 25W/25W x2 Flasher light Front 12V 10W x2 Flasher light Rear 12V 10W x2 I have Head light 12 15/15W x2 Flasher light Front 12V 8W x2 Flasher light Rear 12V 8W x2 Relay is 12.8V 8W x2 So could it be that I have the wrong head light bulbs inside it and therefore the is too few resistance and therefore my flasher lights act slow/weird? Can anyone with a Prebug check their light bulbs please? ( benji PIG spaz12) |

I broke my bulbs when I did my hid install. I do know the 88-90 prebugs are a little different here n there, but I can't find an older manuel. I think all of them are called cw50. Mine had a ground issue that was causing lots of weird stuff, including slow turn signals.

Another weird thing about my 88- both headlights worked oem. Both had high and low beams. My oem turn signals are 10w. Check the lenses, it should say what wattage the light is meant for.

My front lenses or covers don't say anything about Watt. The same goes for my head light. The rear on the other hand says 12v8w and 12v 21/5w    Ok then different approach, where are all the ground wires that go to the frame of the scoot? I know of one which is inside the handlebar cover just below the speedo. And one on the electric starter. Any other? What battery do you guys use? |

Could your pre-bug be a different version. Like pre-bugs built and released in Japan vs. pre-bugs built and released in America? Yes, that could be the case here. I found some Japanese manuals on auctions for $15-20 might grab one and compare it to the pdf that I currently have. |

Says there that you have a 1989 "Big Wheel Scooter" that may have been built in Japan, or by Yamaha, or for Canada. So.... yeah! |

The original Zuma like you have was called a Zuma in Canada. Then the first off the Zumas with the double seat were called the Zuma II. After that every Zuma in Canada has been called the BWS ( Big wheel scooter ). For the front signal lights mine are 10w. As for the rear I have no idea, I tossed that ugly mofo long ago.

Got me a pair of 10W bulbs and replaced the 2 front flashers. Now I have 10W front and 8W rear. Now they flash in a good pace as it should be. Even if I pull the brake all seems to work fine now. Just hope the flasher relay (2x8W) can hold it. If not I still have the other relay (2x10W) and I got also a set of 10W bulbs for the rear so worst case I go full 10W for the flasher lights.

My 88 was called a "riva Zuma II sports scoot bws" and it came with a single seat haha. I'm guessing the light differences are cuz of laws in different countries?
Alot of the ground wires get spliced together in the harness to save space. Instead of getting attached to the frame, several of them actually run straight toothed battery through a series of splices. I found that replacing those splices with ring terminals and making new frame ground attachments a better way to go. I'll try to take some pics.

Could a burned or weak head light bulb cause the flashers to flash slower?
