I wouldnít go full DC without a battery. If you donít want a battery a small capacitor can do the trick. Honda did it for years on the XRs...

I had a little fun today.
I scrounged up a used 150cc cylinder, piston and head from a VBC super.

After a bit of cleaning, some installing and surprisingly very little swearing it was running.

It started 4th kick which is better than the 15 kicks or so that it usually takes.

Short little test ride and it pulls uphill nicely but I'm out of gas.

Rode it into town for a splash n go.

There was one small problem. When I got home I noticed that my taillight bulb had blown again. First ride with the brand new bulb and it didn't last 20 minutes.

It is a good day.
Be nice if it was not 34 degrees and windy on the east coast.
Enjoy the riding.

Oh yeah 34 degrees doesnít sound very nice. Today I was complaining about it being 58 degrees.

Get yourself a set of these tires, a nice up and over pipe and go here?

You could try the correct bulbs based on the wiring diagram. http://www.scooterhelp.com/electrics/wiring/VNB1.pdf

The regulator is still a very good fail safe option. Definitely would not install another bulb until one or both options are done.

Nice ride!

No I havenít done that yet. I know I should.

Itís just like me to waste a day for a few more CCís instead of fixing a known electrical problem.

Where does the voltage regulator go?

My electrical diagram looks like this one is except I donít have the pilot bulb.
Could that be the problem?

That could be the problem...no pilot bulb. Use the correct wattage for all the bulbs and make sure grounds are clean. If that dont work, get a 6v regulator and place in glovebox.

I'll defer to Safis on this one - he has a ton more knowledge then I do.
That said - the LED's I used were such a nice upgrade - I couldn't imagine going back to incandescents.

Your tail is burning out likely because it is getting too much juice when you were at higher revs - perhaps due to wrong or missing bulbs as Rowdy pointed to. Some swear by the regulators to rid the system of bulb killing spikes.

I'd be tempted to contact SIP - they will answer the phone if you call - and ask them how people do it - or follow up with Safis idea of a small capacitor - that seams like a nifty solution.

Below are the links the what I used.

2 for $10

Also 2 for $10
https://www.amazon.com/gp/product/B073TBR62T/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1

The second one were the lowest profile ones I could find - and they just barely fit. I might have had to even modify the bas a little now that I think about it. I ordered them in red - and I'm glad - because they are so bright, they would have made the tail light look clear when I pressed the breaks.

Gratuitous example. Don't mind that thing hanging off the side of the scoot. Not even stepping on the brake here. LED's are just so effortlessly bright.

A regulator is ordered.

For now itís on to other things.
Got a VBC1M engine on the bench an I canít get the clutch off.
Am I missing something?

A couple big screwdrivers and gentle prying on opposites sides to finesse that baby out of there?

That is the method I have used in the past. This one wonít budge.

Iím thinking about trying some sort of puller along with heat and some freeze spray.

Success.

I got the clutch off with a little help from a puller.

The fingers on the puller kept spreading and making contact with the case.

I used the ring from a crank bearing removal tool to keep the fingers held firmly against the clutch.

looks like the crank might be knackered.

depending on budget, a new crank is the way to go
elsewise follow the above link and feedback how successful you were

Thatís nice work.

Fortunately I have a used crank that is in good condition so I wonít have to attempt the repair.


I found some bits of what looks like brass in the bottom of the engine.

I donít see any part of the engine that it might have come off of.

Any ideas of where it might have come from? Something I need to look for?

Yeah, no. From the other thread.

I'm very skeptical that a fix like this would work on the clutch side, there's no taper here(like on a smallframe motor), so the key is doing most of the work and the key is much larger to deal with the load. Any JBWeld in there would be hammered pretty hard and you've got problems if the key starts to get loose. On the flywheel side there's no hammering on the key if it's properly tight on the taper and it's not transmitting power to the back wheel.

Meanwhile I'm waiting for modkuo to get the lead out so we can see if he gets spark and find out if his new FW stays put.
