    You should be prepared to satisfy any insurance requirements. Please enter your zip code below to get started. ZIP: What is a camshaft on a motorcycle? The camshaft consists of a few cams or lobes attached to a metal shaft that is driven by a gear and chain, and rests on bearings. The cam chain connects the camshaft to the crankshaft. As the crankshaft turns, so does the camshaft. In the best case scenario, a misaligned cam will result in a poorly running or non-running engine.

    In the worst case scenario, a misaligned cam will result in bent valves and broken pistons. How to Align Timing Marks on Cam and Crankshaft Before you take apart your engine, be sure to read the shop manual and take notes and pictures of how the camshaft is installed and aligned. Take notes and make your own timing marks if necessary.

    Remove the cam chain tensioner. Slide the camshaft through the cam chain. Align the timing marks on the cam with the sprocket and cylinder head. Tighten the camshaft holders. Reset the cam chain tensioner. Confirm the cam marks are properly aligned. For double overhead cam engines, make sure to count the number of cam chain links between each cam shaft sprocket. There is a specific number of links that should be between the two camshafts.

    Ensure both sprockets line up with the correct engine markings. Refer to your motorcycle shop manual for the specific cam alignment instructions. Cam chains will typically be endless or come with a master link. When you are ready to slip it over the camshaft make sure that it is properly engaged in the gear teeth on the crankshaft below.

    Setting the Cam Chain Adjustment The last step in installing and timing your cam is to set the cam chain adjustment. Your motorcycle will either have a manual or automatic cam chain adjuster that bolts onto the cylinder block. Install the cam chain adjuster in its loosest position and bolt it onto the cylinder block. Set the adjustment by loosening and retightening the bolt and lock nut.

    Refer to your shop manual for the specific procedure. If your engine has a lot of noise, it could be due to a worn cam chain. You may be able to reset the cam chain adjuster to take the excess slack out, if not, you should replace the cam chain as soon as possible.

    I have never seen one on a Tenere, but search for graves tensioner or manual cam chain tensioner install and you will find a few R1 videos which is exactly the same. The biggest issue with the Tenere is the degree crank which doesn't really have a spot where there isn't tension on the chain. Because of that there is a real possibly for the chain to skip a tooth if you are not very careful and keep tension on the chain when removing the stock tensioner. Some other members have posted up how they did theirs.

    Search around and there are some good posts on how to do it. Probably the safest way is to plan to remove the valve cover and check the timing marks after you are finished. Here is a link to a members site where he documents his procedure.. Scroll down the page an you will find the section on cam chain tensioner replacement. No maintenance, except oil and filter.

    Earlier I posted about the inner shaft… thetenerist. As mentioned tension must be maintained or serious damage can occur. You need a tensioner. I chose Graves, but APE makes a good one or there are tons of cheap no-name versions out there. Make sure the tensioner locknut is loose and fully retract the tension bolt. You need a tensioner gasket and a clutch cover gaskets well. Put a socket on the end of the crank and turn the engine over to align the timing marks. I chose to make a spacer to hold the cam chain tight.

    This way I didn't need to remove the valve cover. This greatly reduces the time needed to complete the job, but it comes at a risk. Another member had a neat idea to make a spacer that fits behind the chain guide. I copied his idea and used a short bolt and nut. It fits snugly behind the chain guide and keeps everything nice and tight. The zip tie in the pic is just for easy removal after. Then remove the old tensioner and install the manual one.

    After tightening down the mounting bolts, slowly turn in the tensioner until you feel it snug up. I tightened it by hand as much as I could. Then remove the spacer behind the cam chain guide. Put your socket and ratchet back on the crank and slowly turn the engine over. While doing this use your other hand to hold tension on the the cam chain tensioner bolt.

    You will find as you turn the crank there will be a few spots where there will be a bit of slack and the tensioner will turn in a bit more. Don't force it too hard just nice steady hand pressure. Probably after one full turn you won't be able to add any more. When finished turn the crank over a few more times by hand to make sure your chain didn't skip. Last thing you want to do is hit the starter and bend some valves. Reinstall the clutch cover and you are done.

    Updates Arrive for the 2020 Yamaha YZF-R1

    The rear brake reservoir is heated by the exhaust. Change rear brake fluid regularly as a consequence. There was a recall for the Throttle Position Sensor, which was reading incorrectly and sending false messages to the ECU mapping etc. This could cause the engine to cut out at very inopportune moments. The fifth generation of the YZF-R1 arrived in with a new frame, new swingarm and forks, and six-piston brake calipers. For we see the modern fairing and aero package starting to emerge.

    Check by accelerating hard at around kmh in sixth. The response should be close to instantaneous. The idea was to improve traction through corners. The chassis was a completely new design, and the cylinders were canted at 31 degrees forward. The new firing order revolutionised the bike in regard to tractability.

    There was a problem with the projector headlights melting fairings. This is a warranty claim item, fixed at the first service, but check the headlight housing. Time will tell on the reliability front.
