Okay I'll do that next. I have a volt meter around here somewhere. Do you know the amount of voltage a properly charged battery in a 150cc scooter should put out?

Today out of the blue, when I tried to start my scooter, there was no response from the starter. Additionally, when I turned the key, the lights did not come on, and when I try to activate the turn signals, there is a buzzing noise coming from the front of the scooter. The lights don't blink and the indicator lights on the dash don't light up either. It just buzzes. Also, I noticed now that when I hit either of the brake levers, the gas level needle loses power and drops to 0 until I release the lever, then it raises back up to the proper level. I'm able to start the scooter with the kickstart and once I do that, my lights come on and everything works except for the turn signals, emergency lights, and the brake lever/gas needle problem is still there. Just to be thorough, I'll mention that the brake lights do work when I press either of the levers while the engine is running, but while it's off, none of the lights work at all.

I doubt this is a battery issue but I won't rule it out...what do you guys think? I believe it's a wiring issue but I know almost nothing about fixing a wiring issue or identifying it.

Hey I was wondering, is gasket sealer a long-term solution or does it kinda wear off after awhile?

So not long ago I replaced all the gaskets in my GY6 150cc to fix an oil leak in the oil pan. Well here I am a few months later with an oil leak again, coming from almost the same place. I'm not using an oil thats too thin either, but I am using synthetic.

Anyway, this thing shouldn't be leaking like this. I'm planning to replace the gaskets again, but I wanted to ask you guys if I should also put a thin layer of gasket maker or some other substance on the edges of the metal along with the new gaskets, or should I just use the gaskets alone again? I've heard a lot of people say just using the gaskets alone isn't good enough, and I'm starting to believe it.

So which should I do: just use the gaskets alone, or coat the gaskets with a gasket maker or some other compound?

Howdy.

I know most motorcycles (especially chinese scoots) have a 10-25% optimistic speedometer error. Just thought I'd share what I did to correct it with yall.

I borrowed my dad's dash-mounted GPS and did some speed tests on the roads around here. I tested speeds at 10, 20, 30, and 40 mph. The results are that my speedometer starts with a 25% error at low speeds, and actually becomes more accurate as the speed increases, down to 15% error at 40mph and up. The results:

Speedo Reading - Actual GPS Speed
10mph - 7.5mph (25% error)
20mph - 16mph (20% error)
30mph - 25mph (16.5% error)
40mph - 34mph (15% error)

The error leveled off at 15% at 40mph (and above I assume). So that means my speed at 50mph is actually 42.5mph, 60mph is actually 50mph, and 65mph (my top speed) is actually 55mph realistic. This is all assuming a 15% error.

So what I did was, I just took out my speedometer unit, used a bit of paint to remove the current numbers on the faceplate, and wrote in the correct numbers in their place with a white permanent marker. Problem solved for me.

Not really a revelation or anything, but figured I'd share what I did to fix this annoying problem. You can look at it two ways...it's either a problem with an inaccurate speedo cable/unit, or you can choose to just look at it as inaccurate numbers on the face plate, which is much much easier to fix than fiddling with gears and cables and potentially expensive stuff. If you want to get fancy and you're good with graphic design, you can even design your own face plate in a graphics program and print it out, laminate it, and make it fit your speedo plate.

Yeah if it's anything I hope it's the CVT, because I can access it without taking the engine out, lol.
