Motorcycle Timing Chain Repair Kit – Jialing 70 & Curved Beam 100 / 110 Timing Small Chain, Tensioner & Parts
Motorcycle Timing Chain Repair Kit for Jialing 70 and 100 / 110 Underbone Motorcycles
This motorcycle timing chain repair kit covers the cam chain (timing chain) parts for small four-stroke motorcycles, listed for the Jialing 70 and for 100cc and 110cc "curved beam" (underbone or step-through) motorcycles. You can buy a complete repair kit, or just the individual part you need: chain, tensioner, guide wheel, oil pump wheel, tension rod or tension arm. Easy Life Markets sells all twelve options on this one page, so you can pick the exact piece your engine needs.
The timing chain on these small engines turns the camshaft in step with the crankshaft. As the chain stretches and the rubber-covered wheels and tensioner wear, the engine starts to rattle, and eventually the timing can slip. A worn cam chain is one of the most common reasons these hard-working little bikes get noisy.

How to Pick the Right Chain Length
The most important detail is the number of links in your chain. Small motorcycle engines that look alike can use chains of different lengths depending on the cylinder height and cam layout. To choose correctly:
- Count the links on your old chain, or read the number stamped on it if it is still legible (for example, 82L, 84L or 90L).
- Count the teeth on the cam sprocket if you are buying a repair kit. Style 1 uses a 28-tooth wheel and Style 4 a 32-tooth wheel.
- Match the engine size. The 70 kit suits the 70cc Jialing engine; the 100 and 110 kits are for 100cc and 110cc underbone engines.
If the numbers do not match any option, contact us with your engine details and chain count before ordering.

Signs Your Cam Chain Needs Replacing
- A rattling or clattering noise from the top of the engine, especially at idle
- The tensioner is at the end of its adjustment
- Grooves worn into the rubber guide wheels or tensioner
- Poor running, hard starting or loss of power caused by the timing slipping
Like any roller chain, a cam chain stretches gradually as its pins and bushings wear. Replacing the chain, guides and tensioner together gives the best result, which is why many riders choose a full repair kit.
Installation Tips
- Set the engine at top dead center on the compression stroke and note the timing marks before removing the old chain.
- Check the rubber guide wheels and tensioner for wear, even if you are only replacing the chain.
- Line up the timing marks on the cam sprocket and flywheel exactly before tightening anything.
- Adjust the tensioner as your service manual describes and turn the engine over by hand to check the timing.
- Check and set the valve clearances after the job, and change the engine oil.
Who This Kit Is For
These parts suit riders who maintain their own small commuter motorcycles, repair shops working on underbone bikes every day, and anyone keeping an older Jialing 70 on the road. Buying the whole repair kit is the simplest route if the engine has done a lot of work; the single parts are handy if you only need to replace one worn piece.
Repair Kit or Single Parts?
If your engine has covered a lot of distance and the chain is noisy, the full repair kit is usually the better buy. A new chain on worn guide wheels or a tired tensioner will not stay quiet for long, and the kit replaces those wear parts together. If you have already inspected the engine and only one part is worn, such as a grooved guide wheel or a broken tension arm, the individual parts let you fix just that piece. The chains on their own are also useful for owners who replace the chain at regular intervals as part of routine maintenance.
Keeping Your New Cam Chain Quiet
Small motorcycle engines hold very little oil, so the oil level and condition make a big difference to chain life. Check the level often, change the oil at the intervals in your owner's manual, and adjust the tensioner if your engine has a manual adjuster. Letting the engine warm up for a minute before riding hard also helps, because the oil needs time to reach the chain and guides.
