Hi - my son is 14 and thought a MB hobby may be fun for the two of us.
Welcome to MBc! It is a great hobby to share. What are your plans for your bike?
I was thinking of getting a huffy cruiser and a grubee 48cc kit to start.
What do you think?
That is an OK choice. My first build was a Cranbrook. I love it and ride it often.
There are problems that I am not happy with. 1. Braking....coaster only is not a good thing, I am in process of fitting it with a front brake. 2. Single speed....after running out of gas once pedaling home was a pain. 3. Fenders look cool, but my advice is lose them. Do not try to modify them to make them stronger, just get rid of them.
My next build will be on a Schwinn.
The only mod I plan to do is to lose the front fender.
Good choice on the kit. Stay away from the cheep e-bay buys. There is a vendor review section here that you will find quite help-full.
Welcome to the forum. A motorized bike makes it easy to learn basic troubleshooting. There isn't any electronics except the CDI. You can make parts from things at the hardware store.
I agree that you need a front brake no matter what you have on the rear. You can buy a single brake lever that will activate both brakes from a vendor or on ebay.
What is a CDI?
It is what gives spark to the plug. It recieves power from the magneto and then uses that and a signal to spark the pulg at the right moment.
This is what it looks like.
Here it is on a bike.
If you use the search engine you can find out more about it.
So this may seem an odd question, but would the CDI get fried if a solar flare or emp hit it?
Or is it solid state?
I also highly recommend the "stickies". Here is one with the links to answer many questions you might have. http://www.motoredbikes.com/showthread.php?t=28255
Do not be discouraged by some of the things you read. My Happy Time (slang for the Chinese two stroke) has provided me with many hours of enjoyment with no problems. Yet I will say that it is worthwhile to know of any potential problems.
If an EMP strong enough to take it out happened, my first worry would be concerning the power to my house and my computer.
:jester:Solar Flare might cause damage if it was hit directly......How high do you plan on driving....and how fast.
Not sure but I think it is solid state.....others may be able to answer, I have not found an answer for you so a thread in the 2 stroke forum might be a good place for you to start.
Ever read One Second After?
The ol' Edsel was the only thing running.
Thanks for the link to the first build.
Talked to a local guy - he has a new in the box Grubee Star Fire GT4 for $185 out the door.
I guess Walmart has a cruiser for under $100 too.
The CDI replaced the Points in an engine distributor. The point gap had to be set with a feeler gauge during tuneups or a dwell angle meter. I once caused a sizeable carburator fire in my buddies 455ci Buick because I set the point gap too wide.
Yes, the CDI unit is solid state, which makes it even more vulnerable to EMP than a component assembled device would be, typically.
