How do i remove the battery form an avigo 750 trike to recharge

ebay or avigo

We need a wind screen & front light cover, where can I buy these. Thanks

Get a good one , the cycle place has it.

I'm sorry but your question is extremely confusing. Why can't you just use the battery recommended in the owner's manual?

you can use the computer to charge it via the USB, they do make house adapters that plug into the wall, very cheap to buy, and leaving it plugged in when not in use greatly extends the battery life. Go to ebay to get the house charger

The Tire Pressure Monitoring System (TPMS) gets signals from transponders in the wheels. By modifying the unit from its stock form (removing the stock rear wheel), the TPMS is not receiving a signal and will cause the warning light to illuminate. Unfortunately there is no way to fix this without returning the bike to stock. The light will not cause any damage, but the system will not be able to alert you of low pressure in the front wheel.

charge the battery...see if it holds charge....if not get a new battery

Your first thing is to check for dirty terminals. Once OK, then take it to an auto-electrician and get him to run a multi-meter over it. In about 5 secs he will diagnose your problem and generally it is a freebie service. It sound as if your battery is on its way out. I cant find a freebie manual for your model but have a look any way, http://www.carlsalter.com/motorcycle-manuals.asp

google specs for the 750 that will help you out

Your looking at about 46+ mpg in trike form from what I can gather
