How's it going , i have a couple threads where I've talked about a possible crank issue which turned out to be a starter clutch issue . I decided to make a new thread based on the other threads I've made. Since I found that the issue was the starter clutch , I'm wondering how many decided to scrap their engine thinking the crank was bad when it may have been the starter clutch ? I'm posting a video of my scoot making the noise caused by the starter clutch , so others can compare it to possible noises coming from their engine case. The noise can be heard all around the scoot , however the noise is loudest from the cooling fan side . the second video is after I replaced the starter clutch . I first replaced the oil pump and chain hoping that was the problem . Sadly for me , it was not the issue . I was really worried it was the crank , however I had one more option and that was to replace the starter clutch and if the noise continued I would then know the problem was in the crank . the third is a video of me spinning the bad starter clutch . to me it sounds awful loud . in the videos you cannot hear the entirety of the sounds caused by the bad starter clutch . in the first video you can clearly hear a weird noise almost sounding muffled compared to in person , and there is also more of a metallic noise when heard in person. The third video is the metallic noise I was hearing with the bad starter clutch in . even the third video dosent give any justice to what im hearing in person , anyway I hope this thread can possibly keep someone from replacing the crank or buying a new engine when it may just be the starter clutch. . . .

During the first video when the noise kicks in , the metallic noise also kicks in, and the same when it goes away . maybe it can be hear on a better desktop computer , but I can't really hear in through my phone , which sadly is all I have right now for internet. Also the noise would only start when the engine was starting to get warm . during the summer the noise was more frequent and constant after it began to warm up. The first video was taken about a month after a slight warm up ,and the second video was taken 2day after a complete warm up.

How many miles and what type or brand of starter clutch did you buy. I'm interested because I added a big block kit and I guess we will all be needing to replace this piece at some point in time.

how long after the BBK did the noise start ? If your still using the fixed performance Blue cdi you will damage the new starter clutch.

I have around 18,000 miles on the scoot . the new starter clutch is an NCY high performance starter clutch , paid 39.  free shipping from gy6racingteam on eBay. From what I saw they were the only ones that had them . they do make a cheaper high performance starter clutch for 29.00 if I recall correctly. I had a lot of starter clutch slippage with the stock starter clutch , but it was usually with a weak battery. I'll keep every one posted how the NCY performs . I just bought a new battery so hopefully I won't have any weak battery issues any time soon. |

I have to push my starter button several times as it gets 'stuck' and stops till I push the starter button a couple of times to get her to turn over. I have a 60 BBK. My battery is fully charged on a real car battery charger. So what type of CDI and where did you get it?

I'm concerned because I have a blue CDI and made many mods but I only have one tenth the knowledge you guys have. Scoot runs great, except the start issue.

My battery is fully charged on a real car battery charger. So what type of CDI and where did you get it? How long have you had the battery ? Even though it may read good voltage after charged , it may be weak . best thing to do is to test it under load or jump the scoot off a car and see if it turns over easier . if the scoot starts easier then the battery is probably going bad . its normal for these scoot batteries to go bad pretty quick . When you hit the ignition and the engine just sticks , its usually a weak battery issue . this means the starter clutch is engaged but the battery doesn't have the power to turn the engine over . it can also be a weak starter. Jumping with a car should give you the answer. A weak battery will also cause the S clutch to slip . a weak battery and an advanced Timming cdi may cause kickbacks. I have one of the cheap blue racing cdi's from eBay . I've had it for over three yrs now . |

Battery is as old as I've been a member. I think she's done. What do you have and where did you get it?

Mr. P
I have the same BBK and can tell you8 with absolute certainty you should DUMP the blue (advanced curve) CDI and get an "ADVANCING curce" CDI from tvnacman. It's one of the best improvements you can make - they are great.
HOWEVER
It will not fix the problem with having to push the starter button several times. THAT is caused by the puny, chicken shoot starter motors that come on these things. The motor turns the engine until th etop oc compression (which is way higher than normal with the 60mm BBK), then freezes because the starter motor just lacks oomph. After several button pushes you get the engine past this point, it spins and your scooter starts.
The only solution to this problem is a high torque starter motor. Or patience.

Just get a battery at walmart. Good and great price.
But the problem you describe will not be fixed with a new battery

HIGHLY recommend. ps: got the el cheapo variator this afternoon - will let you know tomorrow. If I understood correctly, the new KOSO is a disappointment. Right? |

I'll check tvnacman now and order the CDI. I've read about it enough here to feel right and good about making the purchase. NOW.... Please my friends, point me in the direction of a starter. I removed the kickstart because it was a pain while removing and reinstalling the CVT cover thirty times, about, testing weights and doing all the other stuff we do.
Anybody feel ok without their kickstarter or I'm not being smart.

I bought one of the gold CDI's and I fried it because it was for AC OR DC. I'm confused which I have but my scoot runs with the battery disconnected. Tvnacman, can you send me a link to the part or hook me up somehow? Thanks.

Can you hook me up with a link to the CDI that we have been discussing. My scoot runs without the battery hooked up so that should tell you if its AC or DC. Thanks.
