I dont know about your bike but a few bikes i have known have had this 4 down gear configuration. I would say it is meant to be like that.

Take the front wheel off , clean out the mud, free all the frozen parts and grease the brake cam shaft going through the brake panel housing. Replace the front brake cable and you should be good to ride. Hint: If the front brake drum is full of mud you need to remove the rear wheel to clean out the mud and grease the brake cam shaft there also.

Yamaha 4 wheelers are notorious for having bad intake manifolds. They often crack or separate causing problems similar to what you are experiencing. If there is a gasket on the manifold replace it and carefully inspect the manifold for cracks and separation from the metal flange. If your machine is equipped with reed valves inspect them for bending , leaking , cracking, bad gaskets, etc.
Just in case part of the problem is electrical , buy a new spark plug cap. NGK makes a replacement for about $5. The resisters in the spark plug caps burn out all the time. The cap simply unscrews off of the end of the wire. It might be all you need.

If it's a 1300 then 3.7 litres at filter change. Smaller bikes, obviously less.

Your existing kill switch, when applied, completes a circuit to ground. The tether does the same when the tether is pulled. You can tap it into the kill switch.

I have just finished restoring a 1981 model XT250.
The best advice I can offer is to take your digital camera and record as much info as you can about the way all the cables are fed through the bike also pay close attention to the way the wiring harness lays.
You will find all kinds of diagrams but photos are much more reliable for me.Photograph every thing even if it seems obscure it will help!!
Find heaps of containers for all the bolts bearings and odds and ends.Keep a roll off masking tape close buy and write info ontO the tape and attach it to the containers or the parts.
This will help when you try to screw the mirrors on and find out that one is a left hand thread.
When dismantling the wheels put the axle back through the wheel and all the components and put that nut back on secure.
Its little things like keeping the bolts in there right place that will help when reassembling.
If you can screw the bolt back into its original hole after removing a component do so .
The most used tool I can recommend would be a decent wire wheel on a bench grinder(a grinder that is bolted to the bench)
You can bring almost any bolt that looks like rusted **** back to new and it will take off paint and scale no trouble.
Very fine steel wool for your chrome .
Get a manual .The digital ones are ok up to a point but you should buy one form Clymer
hope this helps.
Good luck

Sounds like a battery that will not hold a charge. When the battery is low all the juice goes to the starter. Not enough left for a good spark. Kick it and the juice is there for the spark. Once running for a short bit the battery gets recharged so the key works all day. Then the battery dissapates the charge overnight.

Befor you spen $50 or so on a battery, look to see if there is water covering the top of the battery plates. If so then the current battery needs to be replaced. If not, add water to cover the top of the plates and ride it for a day. See if it holds a charge now. Battery may still be bad but it was worth a shot.

probably, alot of these sprockets are almost the same size so often when they are checking for compatability, they often mistake since they are close. If you bought it from a dealer, take it back with your old one and make them put a caliper on it to measure it properly.

Hi, Anonymous the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.
To download your manual for viewing or printing please click on the blue links below. Good luck and have a wonderful day.
