How do I start my bike? Lift stands, squeeze a brake lever, and press starter?

[cyborg]

No switch on the center stand,, but a side stand may have one,,, and the brakes need to be applied before power goes to the starter

apply both brakes? Or just one?

[cyborg]

If all jmstar's are the same, this manual says to completely close the throttle and use either brake. Maybe there is a safety on the throttle.

2. Completely close the throttle grip.
3. Apply either brake and push the start
switch to start the engine.

Check the brake light bulb,,,may be blown and not passing juice

[cyborg]

There's a number of things that can cause the no start,,,bad start button ,,,solenoid bad,,,bad starter,,, blown main fuse,,,,cross the two big terminals of the solenoid with a screw driver to see if you get it to spin

I'm in Akron

So far all I have done is get it home and cover it in my driveway. I have some more questions. How much oil and what weight oil does it take? And what coolant and what ratio with water? Hopefully tomorrow morning I'll get a battery and see if it cranks.maybe try to start it for a second just to hear it run. (Onky for a second if it has oil) Is the SSR model something special? Or just a bunch of stickers? Thanks for all the info so far! Great people here.

Ssr is a middle grade scoot,,,not bad

Oil? Drain from underneath. Remove the oil checking dip stick and slowly fill at that point. Fill till it looks near the top and then use the dip stick to check. DO NOT SCREW IN the dip stick to check your oil. It should read on the dip stick measure without screwing it down.

For the coolant, I use Prestone 50/50 that I buy at WalMart.

Start with throttle left alone, either brake must be on. I only start on the main lift as the auto rich controller puts the wheel into motion instantly on my scoot. The rpm's go well up into the clutch engaged position. It takes from one to two minutes for the engine rate to slow down. Then you can go ride. So start, put on your helmet and gloves while the engine slows down, then go for the ride.

Thanks cyborg and Bobf. Here's what I found so far. bought a battery, put it in. only the lights and horn work.s o I put it on the center stand, still no start. So I pulled out the starter switch not connected. Hooked it up now it cranks can but won't start. Gauge shows 1/2 tank if gas. It ran last year (so I'm told). The engine is upright. Honda (clone?). Is the sparkplug on the left side as you sit on it?

[bobf]

Spark plug on the left side as you sit on it.

I would replace the gas and put in some SeaFoam cleaning agent. About an ounce for each gallon of gas in the tank. It is a cleaning agent that may help loosen things up that have been sitting too long.

Plug is near impossible to get too so you may need to take off some panels if that is where you want to search. Possibly just take off the seat and loosen the side panels mounting screws so you can slip them around a bit for views and access without taking them completely off. These scoots are not designed for service access.

On mine I also have the rear box and such also blocking removal. If serious then take the covers off so you can follow the hoses and wires from front to rear. To take the covers off you will also need to take the foot rests off and maybe even the mid way covers over the foot area. Not exactly sure how your scooter looks. If not necessary to remove the covers, don't do it. I had some troubles with misaligned when trying to reinstall. Once you do have them all off, leave them off till you feel sure you are ready to ride, not more fixing to do.

Bobf thanks. My bike looks almost identical to the picture of yours. No loovers below the windshield. Lower fork legs exposed. And it says SSR MOTORSPORTS on the legs and below the footboards. It has the radio also but I doubt it works and don't really care. If it can be reliable and get better mpg than my Chevy Silverado I will be happy. Can't wait to ride!
