Concealment of a 2 stroke

[pucksterpete]

Do you think a welding blanket, made of flame retardant flax canvas and a working temperature of: 1000° Fahrenheit, 537° Celsius, would work to conceal 66cc HT 2 stroke engine on the frame of the bike? Would the blanket be able to handle the Temps of the engine? How about some other kind heat resistant light weight fabric or another idea?

Thanks,

Pete

That would over heat the motor....boom!

This was done last year by a member, he made a set of side curtains which masked the engine.
I use a grid over which I attach black shopping bags from a local store. Mine is a 4 stroke but the principle is the same. You must have air able to circulate from front to back of the engine and bottom to top. No problem-but, the sound level is needed to be addressed also.

Do you think if I was able to use a breathable heat resistant fabric I would have enough air flow for the engine to keep cool?

No. I have the idea you want to envelope it.
You must have decent airflow and even a furnace filter wrapped around the engine would have resistance to cooling at low speeds. There must be an open area at the front to allow air to go thru the fins and an open area for the heated air to exit.
A covering on the sides only would be fine.

Why do you want to hide it?

 

[motorpsycho]

really...why hide it?
show it off man!

use plates of polished stainless steel on the sides, open front and rear ,the plates will reflect the surroundings. It sometimes is done in magic tricks.

I would love to show it off, but the French want me to have plates, registration & insurance. For me to have all these things I must have a "certificate of conformity" issued by "service des mines" and to get that, the bike must go through a series of test to prove road worthinesses (which will cost $$$), just like a car or motorcycle would. Because it has a motor, it can't be driven on the bike path, so must be driven on the street and for that, it must have lights (no problem), turn signals etc etc etc. Its just a BIG pain in the A S S here in France. They are basically classifying it as a moped. Even the Solex has all the same regulations. So, I just want to make it less noticeable from the street when I ride it on the bike path, so when the cops do go by they see me riding a bike and not have to do a double take if they were to see the motor.

I have the same problem here in the UK, I wanted to do the whole legit route but couldn't find an insurance company that would cover a motored bicycle! Instead I'm Getting myself a friction drive kit and partially covering the engine so from a distance it looks like a pannier and rack! I also found a company that sell various heat absorbing/reflecting fabrics that I'm using to line the inside of the bag. As long as you leave a gap at front and back for airflow it should be fine.
