My 150cc Roketa MC-23 has running lights with ignition on & running as well as brights. I would like to add a switch that kills the lights altogether - but when I deactivate the switch, I can use the lights as I normally would. I am new to electrical, so I am unsure how to wire a optional switch (I am thinking about getting one at walmart.
________________________________________________ 2.
My speedo reads like other scooters - 10mph slower than what it should be reading - this was GPS verified, but in the end I went roughly 54MPH top speed. Q: Is there a way to get the speedo to read the actual speed, or is this the way it was made?
This is all for now - thanks for any guidance on this. Nick

No good reason to turn off the lights. The speedo is something that cannot be calibrated.

Don't think you can have the lights run normal when switch is off either unhook the lights and use a toggle switch from battery or leave them as is. The speedos are un fixable only thing you can do is remark the Speedo with tape and marker indicating correct speed from GPS readings. Mine is digital so nothing I can do at all and mine is 8 mph off at top speed even though its digital I figured it would be more accurate but its not.

I think you mean the speedo reads faster, not slower. This is typical of basically all 2-wheeled vehicles for some reason, and has been stated, hard to overcome. You just learn to live with it.

Yea just put numbers from 1-? and stick them on the outside of the protective plastic like this. This is my instrument panel on the Trike. Alleyoop

I wonder if I can dissassemble the speedo enough to remove the pointer, and replace it a few degrees behind (back) much the same as you can do with a clock hand. It would start out below the 0 mph mark , but maybe it would work

If the error was linear it might work.

I've gotten used to the speedo off, but its no big deal.
As for the lights - I was wanting to run a switch so I could have it off at the shop when working on it (wouldn't need it on) I wouldn't have it off when running in the daytime. Besides, the model bike I have - there is only one headlight on at a time - not both which all model MC-23 are the same way.
Was there a retrofit article that explained how to fix that?

If the error was linear it might work. I was wondering about that,If it's a mechanical (geared) speedometer, I don't see any way that it could not be linear. Ratios should stay the same throughout the range.

Concerning your wanting to shut off your lights while working on it in your shop. If you follow the BLACK wire off the ignition switch(which carries the 12vs to the system, you will find that it goes into a PLUG with about 6-8 wires. Now you will most likely see in the plug several of the wires are jumped so that certain accessories get juice as soon as you turn the key on and others when a switch is turned on. So you either cut all the juice off or you have to test the wires coming out of the plug to see which are directly feeding juice with the key on to which accessory or you can follow the wires to it's destination. Then when you find the accessory or light you want to bypass with your own OFF/ON switch you can splice into that one. Alleyoop

thanks Alley for the tip - will look into that.
I installed a new fuel sensor on the bike today - I saw that the sensor arm was bent backwards than what it should have been (didn't look tampered with), but if the arm was at the bottom of the tank, it read full, if at the top - it read empty haha - I bent the arm the opposite direction and it reads properly now tho. The wires matched the same on the bike.

Don't do it.
When you turn off the lights like you describe all the wattage that should go to the lights will go to the regulator. You can fry your regulator that way.
Some background -- you have a permanent magnet alternator which puts out whatever it puts out and varies with the motor speed. Unlike a car, it is not regulated at all. The voltage regulator shorts out the excess current to ground when the voltage rises above the set point. If you lessen the electrical load on the scooter it gets added to the regulator and overheats it.

I don't understand why the speedo shouldn't be off consistently but inconsistent it is. I'm off like 8mph till about 30, then I'm off 10mph till about 50, and then it doesn't even pay to look. I'm reading close to 80 when I'm going 60. At about 55 forward I look at the tach because between 5500 and 6000 is somewhere between 55 and 65.
I use the GPS as a speedo if I plan on going on the highway to be safe.

I use the GPS as a speedo if I plan on going on the highway to be safe. I'll never understand how the scooter-manufacturers can perfect fuel-injection, but can't get a speedo to NOT read 5-10 mph "optimistic"... I think it may be subconsciously "intentional"... LOL! Nothing builds the old ego of a rider seeing that speedo reading 65 at WOT. Of course, it may keep the number of speeding tickets down a little! My "new" old Kymco has the fanciest dash you might ever want... All digital, speedo, tach, water temp, fuel gauge, clock... The speedo is changeable from "Chinometers" to miles, and the clock from 24 hour to 12 hour with a mere push of a button... All backlit, everything works. It even remembers all the settings when the battery is disconnected. It looks like something out of Darth Vader's kitchen. AND... The doggone speedo is STILL 3-4 mph fast! Come spring, I'm going to upgrade the present 62 mph "J" speed-rated tires to 92 mph "P" rated for safety on the freeway. (Besides, this old-school, pseudo "Italian-esque"scoot is just BEGGING for wide-whites). So I thought I'd also up-size the front tire from the factory 120/70-12 to a 130/70-12 which should about "fix" the speedo error. Duh... The front fender is SO close to the tire that you can't even get a pinky between the tread and the fender. No way can the front tire diameter be increased any. All that being said, little "Minnie Mouse" feels like a Cadillac, accelerates hard, handles like a 150 in town, tops an HONEST 75 mph and cruises at 65 mph as easy and laid-back as my old Harley bagger did. And gives OVER 70 mpg gas-mileage in-town (even factoring in the optimistic speedo). Keeping in mind the old gal is SO enjoyable, even with some serious miles on her clock, I guess I can forgive the typically goofy speedo... The funny thing here is that my old Xingyue 150 actually had a ACCURATE tach and speedo! Go figger! Probably the ONLY one China ever churned out... LOL!
Much like a good woman who can really cook, but ain't no Barbie Doll, you just gotta love and appreciate these for what they are...Leo (watchin' the speedo read 24 mph over the limit, instead of the "Texas-acceptable" 20 over...) in the land of flat armadillos
