Engine Noise

[darrsi]

[size=1em]I've only had it 300 miles, can't be sure i just missed it when I bought it is the problem there. I've read a few things here about resetting the cam tensioner, sometimes they get stuck but they can also be noisy when near the next notch, etc. Not sure if that's the sound it makes or if something else underlying? [/size]

[size=1em]I tried the screwdriver to ear and does sound much louder in the cam chain location but also assume this would be normal given it is in the middle of the action. The more I focus on it the more it's coming from the top of the block rather than things around it, so valves, cam chain, etc.[/size]

[size=1em]As the bike is new to me, I'm planning on changing out the filters, oil, check valve clearances, etc. While there was going to reset the tensioner, given the location easier while tank is off and can move the carbs out of the way. Honestly was considering a manual tensioner, I see some people swear by them. [/size]

[size=1em]Is flushing common, I've always been put off by horror stories of causing more damage than good by it. But then it's done 5.5k miles since 2006 (600 since 2017) and thinking there could be some build up with all the start/stop. [/size]

Flushing oil is not something i would do, just change the oil within spec and everything should be good. Recommendation is every 6000 miles, but i always do mine between 4 or 5000. Try not to get mugged off with mega expensive oil either, because it all has to be of a certain grade anyway.


Depending on your riding style, or journeys, will determine how quick the tensioner forwards another click. So it could be months if you take things easy.


After you have put new oil in, with the bike on the centre stand, start the engine for 30 seconds then switch off and let it settle, this will then be your correct level.
You really want the oil to be towards the upper level of the window markings.


Been using this brand of oil for years now, it's absolutely fine and a decent reasonable price.

I actually use the fully synthetic version, but that's a personal choice thing. Either will work fine though, just don't mix them.
