Yamaha - Starter Clutch Assembly - 4KL-15570-00-00

I have a 2001 Yamaha Riva 125 scooter. The starter was not always engaging and making a lot of noise. I talked to the dealer and they told me it sounds like the starter clutch is bad. They wanted $350 to repair it. The only problems I had was not being able to tell if it was bad or not and getting the crankcase gasket on without tearing it.

"Perfect Condition only issue is some of decals are peeling" ! Summary of Craigslist ad for a 2004 Yamaha Breeze I bought. On last visit to inspect it before I bought it, there was a slight problem with starting, the starter would not engage and would just spin. Then it started. Long story short the starter clutch assembly was going bad. Local Yamaha dealer wanted $108 dollars for what they called a mandatory diagnostic inspection (in other words, $108 dollars just to come through their door). Their cost for just the starter clutch assembly part was close to $130.00 (incl tax). So it would have cost $238.00 before any real work started. I figured they would have charged me over $500 for the repair. Boy!, by this time my wife was really mad at me for buying the Breeze (I wasn't to happy either).

So onto Google I went to research the problem, repair and find the OEM parts for the repair. Downloaded a Yamaha Service Manual ($5.99). Reviewed numerous on line forums. Pinpointed the problem and learned that the repair was not difficult.

REPAIR: Remove seat, center cover, front cover, front fenders, foot board and bracket, left crankcase cover, primary fixed sheave, primary sliding sheave and you are at the starter clutch assembly. You simply slide the old starter clutch assembly off and install the new starter clutch assembly and put things back together. Biggest thing to watch out for are the removing of the 12 Phillips head fasteners on the crankcase cover and the nut holding the primary fixed sheave on the shaft. I used a #3 Phillips head on a hand held impact tool (from Sears), same size head screw driver, and WD40 Penetrant spray, to slowly remove the crankcase fasteners. The key to taking the primary fixed sheave nut off is to hold the CDI Magneto nut. (Do not stick a screw driver between the fins of the sheave. The fins will just break off.) Time for a novice to do this work was about 4+ hours. I would do this work again.

PARTS: I found everything I needed at 2wheelpros and the best price for the starter clutch assembly. I also bought some additional parts (engine oil drain plug, oil strainer, filter elements....)

SUMMARY: I was very pleased with the ease of finding the parts I needed on the 2wheelpros.com web site, the ordering process, and the fast service / delivery of all the part I ordered. I know 2wheelpros will be my first stop when shopping for parts for our Yamahas - TW200 and Breeze.

I have a 125 yamaha grizzly that runs well until it gets warm and sometimes will die and won't start until it cools down. The starter just spins. I thought originally bad starter and took it to local dealer and he bet it was the starter clutch as many have had same problem. He quoted me 4 hrs labor at $125 per hour and $130 for part. Wow. I decided to pass. I googled starter clutch and read some of your forums. They were right very easy fix with basic tools. Got an impact screw driver $10 at auto zone, starter clutch assy $72 and about 1 hours time to fix.
Start by taking off left side foot rest assy. Then take off the bolts holding the black snorkel tubes and fold out of way. Use the impact screwdriver to remove case bolts ( don't try regular driver you will strip them out.) The lower one that you can't get to use regular screwdriver and hit with hammer to loosen. This side of engine does not have oil in it. After removal of case you will see an aluminum wheel with fins and a nut with a locking tab. Bend the tab back so you can turn nut off. Now for hard part. Use impact gun to remove nut. If you don't have one don't use a screwdriver to try to hd fins they will break off. I used an oil filter wrench to hold wheel while I broke nut loose. Once this is removed you can slide this off then the clutch assy, install be one in and start assembling together like you took apart. I found the hardest part was figuring out how to remove that nut without damaging fins. Quad rusts great and will probably expect to do this again in 4-5 years as I guess the dust gets to them and wears them out. Some people have said they clean them up and oil them but I figure while you have it apart might as well put in new one. Good luck!
