Mini Moto Tips
Here are some quick adjustments and tips for the B1 Liquid Cooled Mini Bike that I have found helpful.
Additional protection against heat:
To protect the bike, I have put aluminum tape inside the fairing at the point closest to the exhaust and at the bottom of the fuel tank. I’ve done this because the engine gets so hot that I wanted to protect the fairing from melting, and it doesn’t hurt to protect the fuel tank for the same reasons!
My tips on the cooling system:
When you run out of cooling fluid for your B1 rep, use distilled water which is available at your local garage, add a little food coloring so you can easily tell the level, and you’re done.
Just fill the reservoir to a quarter full, this is enough coolant and leaves room for pressure.
Once you have filled the coolant reservoir, there are often air blockages in the system. To get rid of these, start the bike and let it warm up, then bounce the bike (gently) on your rear tire with the bike in an upright position. Do this several times, this should eliminate airlocks in the system and prevent overheating. You may need to top up the coolant level now.
Where not to ride:
Hi, I just bought my new air cooled B1 from you. Thanks, it’s a great bike. A quick tip for your other clients. DO NOT DRIVE YOUR MINI MOTORCYCLE ON THE ROAD. My friend (who also rides a mini motorcycle, but on the tracks where they are supposed to drive!) Is a cop (boooo!) And the law is very strict:
The rider or rider of a motorized scooter or bicycle on a highway could face heavy fines, license endorsement, disqualification, and in the case of dangerous driving, up to 2 years in prison.
Remember that the term road includes not only a carriageway but also sidewalks and shoulders and also any road that encompasses trails, bridleways, and secondary roads.
You can also include privately owned roads that are accessible to the public and, in some cases, have you included parking lots?
Parking warriors beware !!! ???
Here is some good advice. Before riding your mini motorcycle, you will need to make sure that the wheels and chain are aligned. That is how. Loosen the bolts on the rear wheel to be able to move it. Place a perfectly straight piece of wood (I used a meter) against the front wheel. When the front wheel is straight, the gauge stick should be flush with both the front and rear of the tire. So it is a simple case of aligning the rear wheel. The chain should now also be straight.
Changing the gear of your mini motorcycle is simple. A larger front sprocket combined with a smaller rear sprocket creates a smaller ratio, this means the mini bike will have better acceleration but less top speed. A smaller front sprocket with a larger rear sprocket will give your mini bike better top speed but slower acceleration.
Here are the possible shifting variations: The lower the ratio, the faster the acceleration. The higher the ratio, the better the top speed.

I tested 7/56 with my B1 rep at GP Karting, I think this is the right thing to do for that track as it has a lot of tight corners. I might go to Stretton soon so I can test my 7/68 setup. This should be good for straights, however it may take a while to catch up!
