The only thing with LEDs though is that they will blink on AC power... They are diodes, after all.

I wrote that sitting under my LED house lighting, which, if it is blinking, is doing it so fast I can't see it. That doesn't mean you are wrong, as I have no idea what cycles the lighting coils put out. A WAG would be one cycle per revolution. If that is right, I don't think you will be able to see it happen...ARH

A lot of LED house lights use a bridge rectifier to turn the electricity from AC to DC, if they didn't, you might be bothered by the pulsating effect that they have. If you look at cheap LED christmas lights, some people (I am one of them), can see them pulsating at 60hz, because that is what the power in the US cycles at.

On one of these bikes, the frequency that an LED would pulsate is dependent upon the RPMs of the engine... I'm not sure what the frequency would be, but a cheap bike LED would probably not have bridge rectifiers to turn the AC to DC, so while it might not be as noticeable at higher RPM, it might be visibly cutting out at idle, kind of like how an old AC powered light would appear dimmer at lower RPMs (but for a different reason, lower voltage). Usually smaller single LEDs, unless specified differently (like wired in parallel), operate at 1.5v.

The ones I have bought for my car are 1156 and 1157. Package says will operate between 8 volts to 20 volts...ARH

With all that aside, my $120 grote led light will be fine. On another note, before i even attemp to fire it up, i want to adjust the valves. Is it .003 intake, .004 exhaust? I will also adj the chain tensioner, but the starter motor sure looks in the way.is there a known block off for removal,? Some bikes can take freeze plugs to block it off.

:) Honda always said 0.1± 0.02mm https://plus.google.com/photos/10536...48744657475970

On Both? Usually the exhaust is a little looser.

IN=EX are recommend by Honda in many small bike https://drive.google.com/file/d/0B2b...ew?usp=sharing

Ok. Thanks. Word on the starter?

JerryHawk250 11-08-2017 12:03 PM

You may be able to use something like this. Just need to find the correct size. https://www.amazon.com/Needa-Parts-2...AB79JRQDYXB5FH

I would just make a block off plate out of 3/16th - 1/4 inch aluminum plate. Make a paper gasket out of an old breakfast cereal box, and bolt it on in place of the starter...ARH

We have those at work. Thanks

If I remember right that should be about 30mm which is about 1 1/8" But I would check that. I'm getting older and the remembering is getting worse. lol

Angus67 11-09-2017 10:56 PM

I got the starter out. Looks like a 1 1/4 expansion plug will block it off.
