Electric Bicycles

I run a 35w HID on my Aero, beware though, the stator does not provide enough current to keep the battery charged once you do this. I get about 1.5 - 2 hours or riding before the battery will drop to a critical voltage for the HID (somewhere around 11 volts). This is obviously an issue if you are r...

Re: Does anyone else own a Honda NS 50?

Very cool read about racing the then "new" NS50F back in the day! Just last week I was talking with a friend of mine while racing RC cars at a local track to find out he had bought a Honda NS50F new back in '90. A few days later he saw my bike and it really brought out some memories, and ...

Re: Bike runs well and then dies at full temp and wont start

It can, but let's take a breath, back up and review the basics. What's the three things an engine needs to run? A source of fuel, in this case an mixture of fuel and air that will ignite. A properly time source of ignition, a spark. Enough mechanical leverage to compress the mixture to the point it ...

Re: removing tube in carb

That tube is only the overflow!
Take the float out and let the carb fill to see if fuel comes out the vent.
Simple as that

Re: Bike runs well and then dies at full temp and wont start

Once it boggs down and stops, you should check the spark, it seems unlikely it's electrical, but you should eliminate it as a source of the problem. I would look at the crank bearings and, more specificly, the seals. First, check for any play[movement] of the rotor. You can just grab it and try and ...

Re: Can you tell me about the Aero 125?

I had a scooter shop back in the '80's and I would have to say the Aero 125 was probably the least reliable scooter that Honda made back then. It uses an Alum cyl. that is a little short on fining and was somewhat seize-prone. And I don't recall any over-size pistons. That could be a factor as to wh...

Re: LOW COMPRESSION ON FRANKENSPREE

With such a small swept volume these engines displace, it can be difficult to get an acurate reading with most compression testers which are designed much larger engines. Due to the volume of the hose, adapter and gauge result in low readings The rule of thumb that I have used for decades, is just t...

Re: Possible Clogged Pilot Jet 1984 Spree??

As well as the low-speed jet, you must make sure the low-speed circuit passageway is free and clear.
Here is a Wiki I wrote on the subject years ago over at Scootdawg.

Re: carbon build up

The rounded end of a fairly stiff feeler gauge works well.
If you want to actually get inside the port, buy a cheap set of small files and bend them to your needs.

Re: 1985 Elite 150 Full Restoration - In Progress

How is it going?
You are right at the fun part, hooking the chain on the crank sprocket.
I used to use one of those long flexi-stemmed magnets to fish it on.

Re: Iowa Spree Lands in New Mexico

I've never seen a Iowa Spree that was actually registered in Iowa. Judging by the rust on the muffler, etc., it would make sense to just go ahead and replace the main bearings and seals now. Like any 2-stroke that has been stored "open"[no plug], it will only be a matter of time til the be...

Reliving some memories...

hey, Kinda new here. I owned and operated an independent Scooter shop back in the '80's when scooters were all the rage. I had been working in a major Honda dealership and when I saw how they treated new scooter owners, I figured "Why not?' and struck off on my own. I can't say I ever made any ...
