  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

TE 449 - clicking engine noise on acceleration

I'm hearing a clicking or rattle from the engine upon acceleration. This is a different noise than when you accelerate in too high of a gear. Has anyone else had this? There is nothing loose outside the engine, I looked around. Thanks.

I agree with AZuwere.
Sure sounds like detonation.
I hope you are not running standard octane fuel.
Must run 95 or higher, preferably 98.

You may have checked this but youve not mentioned the chain is correctly adjusted?

Hi Spud
When you check the chain tension do you do it with the bike on a pit stand or with both wheels on the ground. the play they state in the handbook seems very tight.
please advise

The 511 and 449 are unique because of the coaxial suspension linkage. My 449 has about 15mm up and down movement just in front of the chain guard. Also, whilst your checking the chain have a look at the chain guide. On my bike the rear sprocket was dragging on the guide. I fitted a couple of shims to space the sprocket clear of the guide.

ok but is that 15mm with the wheels on the deck or on pit stand?-- I always am unsure!

It was the chain being a little loose. It just sounded like the noise was coming from the engine when I was riding. Thanks, I have started using better fuel too.
