Allowable Weight Limits on the Indiana Toll Road: · Maximum single axle weight 22,400 lbs. · Maximum tandem axle weight per axle 18,000 lbs. · Maximum gross weight ...

Most towing advise works to the 85% rule. As long as the maximum weight to be towed is 'Not' greater than 85% of the vehicles maximum 'kerb' weight, (maximum gross weight).
The Musa should not pull over 1000kg, (1 metric tonne). A braked trailer will allow that weight to rise by about 200kg.

Minimum troubleshooting:

Battery might still be bad, even though it's charged. A bad battery cell will fool you every time.

Remove battery and take it to any auto parts shop. Always disconnect negative (ground) cable first. When reconnecting, connect positive (red) cable first, then negative. Battery clamp bolts should be torqued to 60 inch-lbs only. If you don't have an inch-lb torque wrench, buy one. Battery should test at 12.5 VDC. The load check should show 270 CCA. If the battery fails, replace it with a Harley battery only. Bargain brand will only give you grief.

If it's not the battery, then you need to take the bike to a shop that knows what they're doing with electrical - most of these guys are barely qualified to change a light bulb. If you have electrical troubleshooting experience and a voltmeter, get the shop manual for your bike. It has a very straightforward discussion on how to use voltage drops to diagnose starting system and other electrical problems. Don't throw parts at the problem.

If someone has recently pulled the clutch, then it's very possible that the starter jackshaft retention bolt has been over-tightened. Book value for torque is wrong. It should be no more than 15 in-lbs, otherwise the jackshaft can bind.

That is a hard question to answer. Your range of distance can differ due to terrain. If you are riding the chair around the mall you might get 5-7 miles. If you are riding it on a sidewalk you might get 3-5 miles. If you ride it in the grass you might get 1 mile. The best answer I can give you is that most people can go 1-3 days between charges. You also have to consider your weight. If you are 100 lbs or 350 lbs. there are always factors. Since the chair does not measure distance it would be unfair to give you a number based on distance to gauge your battery life. You need to watch the battery gauge and determine what your chair is able to do.

I don't know but would guess about 150 lbs. Check the sidewall of the tires for the limit on the tires. The bike limit is probably linked to the tire limit.

It sounds like you have some sort of suspended bike (details not mentioned in your post) and the preload is way off.

If you bought it from something other than a professional Local Bike Shop it is very likely that it was just slapped together by someone with no clues to how it works or who will own it. An LBS would work with you and set it up to YOUR requirements, fit, weight, riding style, etc.

Name the bike so we can be more specific in our advice. Seek the manual and find an LBS to serve you going forward.

I could not find a weight limit specified anywhere, but it is designated as a man's bike and that should cover up to at least 250 pounds. However, the reviews state things like flimsy, and recommended for light (500 miles a year) riding. 240 pounds will probably stress it quite a bit. You might want to look for something more sturdy. If price is a consideration try craigslist for a used electric or hybred.

Do you know what the weight allowance is for this motorcycle? It should say in your owners manual ...

Not that it directly applies ... my Honda 750 weight capacity is 404 lbs with no additional accessories.

With a 20 year old vehicle, the original towing capacity does not apply.
I'd set a limit of whatever the weight of your vehicle is as a safe number (if car weighs 3,200 lbs, tow weight is 3,200lbs Max.) Trailer weight is also determined by the capacity of the hitch.
Trailer loading should be at 60% of weight on hitch.
Don't forget...you need a fully functional cooling system, adequate (most times additional) transmission cooling, and good suspension (air shocks, variable load rear springs and fresh differential lube). If this is done, you may be able to add 20-30% more trailer weight.
One item often overlooked is that it really does not matter if you can pull a load...you need to be able to stop it. Make sure your brakes are in really good condition!!!

Send them out to a good suspension rebuild shop. Most dealers can ship them for you if you remove them. Factory connection, W.E.R. or others. You will fill out a questionaire on weight, riding style, ability, and what you ride on.
