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...

In that case something in the cruise control circuitry is shorting to earth. Look for places where wires in the harness my flex or rub against the frame or bolts.

you are not alone and Harleys do it as well.

yes be sure you mark everything. each gear to chain to engine.

before you remove tensioner wire chain so they stay tight on the sprockets when you remove the tensioner

Its a carb issue but more than likely the internal passages are gummed up. Its probably because you have been using ethanol blended gas. The alcohol wreaks havoc with small engine carbs they were never designed to run this type of fuel. You can try to rebuild it but I have found it only works about 10% of the time. Save yourself a bunch of headaches and purchase a new one. Try to buy non-ethanol fuel or at add a fuel system cleaner everytime to fill up. The cleaner will extend the life but ultimately the new one will plug up.

Hi, Pat, your title and registration prove what year your motorcycle is, 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 you bypass the Capacitor Discharge Ignition, how do you reckon it will work without any ignition/spark etc.

Yamaha... | Answered on May 28, 2019


Easy and cheap way to increase your speed without messing with the motor,gas,air or spark is to change the sprockets and chain set up on your final drive. Go to gearingcommander.com for all the specs and information on how it will effect your engine and what is best for your year model bike. Ride safe and ride free

Yamaha... | Answered on May 27, 2019


Possibly restricted exhaust or valve worn or piston rings worn take out spark plug hold gently but firmly against the plug hole turn over engine Holding the plug obviously not with spark plug cover on !! It should at least push the spark plug away from the hole with a pop pop pop sound if so hopefully that rules out valves if it's not burning oil then it probably not rings could be timing off or valve seals most engine with leak will run full revs under no load ps also check plug gap :-)
