Where do you put the cam chain on a motorcycle?
You must install them in the completely off (Loosest) position. That is, with no tension placed on the Cam Chain.
What can I do to fix my cam chain?
The real cure is a new Cam Chain. There is always one and sometimes several Cam Chain Guides. These guides can be rollers, Sprockets or plates. They keep the Cam Chain on track as it goes through the engine. Some of these guides can be quite complicated like these from a Kawasaki 700 V-Twin.
What should timing be for worn cam chain?
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.
When to replace the cam chain on a Honda 350cc?
The early Honda 350cc twins had a tensioner controled by oil pressure. Check your shop manual. If the Cam Chain is real noisy and the noise does not go away when you adjust it, the Cam Chain is worn out and needs to be replaced. Just like with the rear drive chain and sprockets, the Cam Chain sprockets should be replaced too.
When to replace the cam chain on a Moto?
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. Every engine will have specific marks designed into components to aid in the timing of the engine.
What happens when exhaust cam chain is worn?
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. This is a good indication that the chain is worn and 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.
How do you know the number of pins on a cam chain?
To do this you will need to know the total number of pins on the chain. It is easiest to count the number of pins prior to installing the chain, however, pins could still be counted with the chain installed in the engine by marking one of the links, rotating the engine around, and counting.
