First, with the worn chain installed I checked the cam timing. Then I installed the new chain and rechecked the timing. In the table below you can see the intake cam timing was retarded by 6.625° and the exhaust by 9.50° when compared to the new cam chain timing values.
Is it worth it to replace the timing chain?

Where are the punch marks on the cam chain?
Both punch marks are visible and in the correct spot. As the chain wears the tensioner will absorb slack and the cams will retard. In this image with the old chain installed the exhaust cam punch mark is far too high in relation to the cylinder head machined surface and the intake cam is not even visible.

Where are the timing marks on a Suzuki engine?
Timing. On most Kawasaki and Suzuki engines the marks are lines on the cam sparockets and should be even with the top edge of the cylinder head. There is one extra thing on Kawasakis and Suzukis. Count the number of cam chain rollers from the exhaust timing mark to the intake timing mark.
How long does a timing chain last in an engine?
This is especially important considering that many modern engines are known to consume oil. In a well-maintained engine, a timing chain can last up to 300,000 miles or even longer.
Why is my timing chain wearing out on my RX 350?
The timing chain problems are not uncommon, especially in high-mileage vehicles. Similarly to any other moving mechanical components inside any engine, a timing chain is subject to wear. A timing chain is lubricated by the engine oil. Lack of oil changes, low oil level or poor oil quality can cause the timing chain to wear faster.

How do you change the camchain on a bike?
The camchain tensioner can stay in place for this operation. Just turn the spring-loaded wheel to release the tension and pull up on the chain. There is a 12mm nut on the opposite side holding an M8 grub screw — undo it and turn the screw clockwise until it locks the tensioner plunger (keep hold of the chain until tightened).
Where does the chain go on a camchain?
The chain sits on the guide of the tool, and the changeable tool head (next to the thread) is set up so the breaker pins push on the link pins. It pushes them through very easily. You can just see them being forced into the slots of the tool.
Both punch marks are visible and in the correct spot. As the chain wears the tensioner will absorb slack and the cams will retard. In this image with the old chain installed the exhaust cam punch mark is far too high in relation to the cylinder head machined surface and the intake cam is not even visible.
How do you adjust the cam chain on a motorcycle?
That is, with no tension placed on the Cam Chain.

What’s the best way to change a camchain?
Using two hammers either side of the link (this does work, in a fashion). Using a nut splitter to “spread’ the pins. Relying on the press fit of the side plate to hold it together (seriously?). Some are even proud of tacking the side plate on with a MIG welder (oof!).
What happens when the timing chain is off on a Moto?
Cam timings that are off several degrees will result in a loss of power and the cam chain tensioner will have quite a job trying to take slack out of the valvetrain. When a timing chain elongates it may not do so in a uniform way and parts of the chain may be tighter or looser than others.
How does a timing chain stretch over time?
Before I get into it, one misconception I want to clear up right away is that the timing chain doesn’t technically stretch. Instead, the pins and rotating elements of the chain wear. When the pins wear they become smaller and their mating holes grow larger leading to increased clearances and chain length.
Is there a problem with out spec cam timing?
On stock engines where clearance between the piston and valves is plentiful less precise valve control normally won’t be a problem nor will severely out of spec cam timing.
What happens to cam chain when timing chain wears?
The remaining problem, which applies regardless of whether the engine is stock or modified when the timing chain has worn, is that the cam chain tensioner will have quite a job trying to take slack out of the valvetrain. When a timing chain elongates it may not do so in a uniform way and parts of the chain may be tighter or looser than others.

Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.
What happens when you change the timing chain on a dirt bike?
When the cam/timing chain gets loose it can slip and cause the teeth on the cam sprockets to jump. The timing is then changed, resulting in poor performance. If it jumps too much then the valve (s) can eventually hit the piston because the timing is so far off.
How much does it cost to replace a timing chain?
Prepare to have a repair budget of around $1,000 to $2,500 for both the parts cost and labor if you’re expecting a timing chain replacement. If, however, you are the DIY type, you may purchase a timing chain or belt and install it yourself at a price of around $80 to $250.

When I set the plunger with the old chain installed the ninth tooth was engaged on the plunger. Observations like this can be used to gauge cam chain wear and to determine when the chain should be replaced.

How many pins between sprockets on twin cam engine?
I like to span around 6 – 8 pins between the sprockets on a twin cam engine. Unicam engines are trickier and the number of pins you can measure is usually less. It is important to try and measure across multiple pins because the variation between new and old chain measurements will be more pronounced this way.
