The information from above gave me the confidence to adjust my chain slack and with Ferret's detailed instructions, I performed the 600 mile initial service this past weekend. Everything went fairly smoothly and I did not have to adjust the chain slack as it was within spec (I measured 25mm). However I did have a difficult time accessing the measurement point (mid point of the chain between the engine and rear sprocket) as the muffler was in the way. Ultimately, I was able to get a ruler in there and take a measurement. However, is the following the correct method to take the measurement?
1. From the chain's mid point, I take a measurement from the ground to bottom of the chain. This measurement is taken without any downward force to the chain as I just let gravity determine this measurement.
2. I then pushed the chain upwards using my index finger while I am laying next to my CB. In doint this, I applied quite a bit of force. I then measure the distance from the ground to the bottom of the chain.
The difference between the two measurements is the chain slack (which in my case measured 25 mm.) My concern is how I measured the two points. In measuring point 1, is just using gravity correct. And in measuring point 2, is it correct to apply some force or do I just want to apply enough force so that the chain is taut?
