Hi, Edward for this scenario you will need your service manual that has all fastener torque specs and a wiring diagram on the back pages, parts fiche, and owners manual if you can not find the best tool you ever bought for your Yamaha, despair not, for a mere zero $0 you can download another one.

Hi, Rob and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the choke.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Quick disconnect check ball stuck.
14. Compression below 75 PSI.
15. A stuck-bent-burnt valve.
16. Improper valve clearance (too tight)
17. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
18. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
19. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
20. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections are loose or connected to the wrong cylinders.
21. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
22. Faulty neutral, clutch, kickstand safety switch.
23. Faulty fuel pump or fuse or relay.
24. Faulty or corroded run/stop switch.
25. Tilt sensor needs a reset.
26. Security system not disarming alarm needs a reset.
27. Check for engine trouble codes.

Hi,Vincent 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.

If it bolts loosening, put some Red Loctite on the threads. If the handlebars are moving in the clamps, put a folded thick rubber band top and bottom and clamp them up.

Sorry but I need more details. I can not see what you see. Please write back and tell me what you did (Step by step) to prepare the caliper for new pads. I think it would be worth double checking your work and the caliper for operation. The rear caliper is a two in one. By pressing down on the rear brake pedal. Do the rear brakes engage? When you serviced the rear brake pads. Did you remove the parking brake linkage? Actuate the parking brake lever. Do you see the parking brake linkage move? Depending on what you find. You may have to adjust the threaded rod at the caliper or you may find that something is wrong with the caliper.

Remove the engine cover, find the carburetor, move the choke lever, see if something moves on the carb. Generally, broken choke cables are very noticeable because they are loose.

I presume this is the first time you have used your snowmobile this year? That means you have stale fuel in it, probably condensation water unless you stabilised the fuel at the end of last season. Your main problem though is that the carburetor needs cleaning.

Did you check/clean your air filter? I had a no start issue with my Yamaha RD350 where the filter box was tight up against the seat and no air was getting into the carb. Do you have compression? Is the cylinder still attached by the connecting rod? Have you recently made any changes (like new jets) or repairs to cylinder or rings?
usually it comes down to an air intake issue if you have a working cylinder in a motor with gas and spark unless your timing is so far off that it isn't firing during the compression. But it might still backfire if it's off?

The gear cogs might have moved or damaged. Better get a repairman to have a look at it.

Yamaha... | Answered on Dec 04, 2019


I always add about 10% oil to my small engines to help protect them from friction. If it starts ok with that much oil, it might smoke a bit and cause a little carbon build up on the plugs or valves, but most engines after 1980 are high enough heat and compression ratio to clean themselves up.
Sometimes the oil doesn't blend in all the way without some sloshing around.
