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.

Hi, Anonymous and the usual suspects are:
1. 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 preliminary 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.
2. 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.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.
9. Improper valve clearance (too tight).
10. Check for generated diagnostic codes.

Remove and clean battery cables, if that does not work look at a replacement battery. Another test is to turn headlight on if possible and observe, if it goes dim replace battery.

If it still runs and rides I would think timing chain. If it was coming from the clutch I wouldn't think it would still pull itself.

Kick stand up or down,clutch in or out? Tranny in neutral with neutral lamp on? Did it start after that one time or it hasn't since? Check switch contacts for both power and start,test start solenoid and ensure power down to starter
Check all ground points and clean em at block,frame and batt posts also. Coat all terminals with dielectric grease. Best corrosion protection.

It sounds like the carb jetting is plugged up so that carbs should be removed and cleaned! When you first start the bike keep it idling by having someone hold it on and at the same time light touch the front and rear exhaust pipes. The carb that is working will have a hot pipe and the one not working will be cooler or cold.

need to replaces your starter coil which seems when it heats up crates short.

Yamaha... | Answered on Jun 17, 2019 | 58 views


First off, I put a brick under the kickstand to get my bike near level...then i gathered the tools needed. 5mm Alan Head (Hex) Bit, 8mm wrench, phillips head screwdriver, and a vacuum pump (not necessary but very helpful if you're doing it solo.

Attachment 51703

Next step is to remove the left rear cylinder side cover. three 5mm bolts hold this in place.


Unscrew and remove the resevoir cap and diaphram carefully. Cover your paint with a towel (I was probably a little overdue for a fluid bleed...)
Suck out the old fluid from the resevoir using the pump (or a turkey baster) and refill with new DOT 4 brake Fluid (or DOT 3 or DOT 5.1)
Attach a plastic tube to the clutch bleeder valve, set up your vacuum pump, and loosen the valve using an 8mm wrench.
Now, get to pumping...watching the level in the resevoir as to not let it suck any air. When the fluid coming out of the valve is clear, the system is flushed.
(NOTE: if you are doing this by hand, (1) loosen the bleeder valve, (2) squeeze and hold the clutch lever, (3) tighten the valve, (4) release the lever...then repeat 1 through 4 about 50 more times being sure to watch the fluid level in the resevoir)
Once you are done, close the valve to 4.3 ft/lbs and refill the resevoir. Then replace the diaphram and resevoir cap.
Put the rubber cover on the bleeder valve and re-install the left rear cylinder cover. Check the fluid is at the appropriate level...

Hi, Anonymous for this scenario you will need your service manual, parts fiche, and owners manual if you can't find the best tool you ever bought for your Yamaha, despair not, for a mere zero $0 you can download another one.
