Rooz Posted March 17, 2022 Share Posted March 17, 2022 Hi, I bought a Keeway superlight 125cc a few days ago and the seller never said anything about the 3rd gear being noisy or having issues! Cut the story short, I went to take the bike for the MOT this morning and I heard a horrible noise in the 3rd gear. it sounded like the chain was gonna come off! I turned around and cancelled the MOT. I've put the bike on the center stand and started it and put it in the different gears to see whats going on and where the noise was coming from and I found out that the noise is from somewhere near the small sprocket close to the engine! This noise gets much louder if im moving the bike but it is still very noticeable even when the bike's stationary and it only happens in the 3rd gear. Please view the video attached: https://streamable.com/d8lrwx The bike doesnt slip out of the gears so this can't be a clutch... what is the the issue here? and what are my options? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Keeper96 Posted March 17, 2022 Share Posted March 17, 2022 If it’s only in 3rd then there’ll be something wrong with 3rd gear inside the box. I’d imagine the only remedy is open the box up and have a look Quote Link to comment Share on other sites More sharing options...

Where is this box and do I need to dismantle the whole engine to get to it? Quote Link to comment Share on other sites More sharing options...

The gearbox is contained in the lower half of the engine casings. to access the gears and shafts generally means splitting open the engine crank case. Sounds like a big job but if you have a good manual and a bit of common sense it’s not beyond the reach of a good diyer. or I’d imagine you could pick a whole engine up for £150-200 from a good breaker?

I thought about changing the whole engine to be honest as its much easier for me to undo some bolts and unclip some wires and replace the old engine with another one. But did a search on eBay and everything is so expensive! everything is £300+ for an old engine! I wasn't planning to spend that much to get this on the road. I thought what I bought was OK-ish happy to spend around £150 for another engine. Quote Link to comment Share on other sites More sharing options...
MikeHorton Posted March 17, 2022 Share Posted March 17, 2022 If your not confident for £150 you maybe able to get the bike repaired Quote Link to comment Share on other sites More sharing options...

But the issue that I have now is that I can't get the bike to the mechanics/garage since I'm worried driving it could cause more damage! and I can only go up to 2nd gear. calling a mobile mechanic is gonna be expensive as they charge a callout fee. Sticky situation! Quote Link to comment Share on other sites More sharing options...
