• 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 The previous version was outdated and no longer supported.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!

Cam chain tentioner 10 clicks out 2300 miles

Well my husky seemed to have abit more cam chain sounds then normal, pulled the tensioner out and counted 10 clicks out, at 600 miles i was at 5 clicks out, does this seem like the chain wore out faster then normal? At this rate i will be changing cam chains at the same rate as tires.:banghead:
 
Yeah i took it off spring first, then the two 8mm bolts. then pushed the tensioner back in to zero clicks before install, that was at 600 miles and now 2300miles. I knew the 610 had some cam chain issues when i was looking to buy one. I just thought i would get more miles in before a cam chain change.
 
Say it's not so, that to me sounds "NOT GOOD". I would hope they last longer than that. Anyone else going to chime in?
 
Doesn't sound good. Are you still on warranty, I hope?
Mine has me a little worried. I counted 6 notches and 7 bumps at around 2700 miles. I wonder what they are new.
 
I was seeing about the same rate. When I checked mine at a 600 miles it was 7 clicks out. I went with a MCCT.
Here are my thoughts from another post.

The MCCT works great.
I can set the tension I want.

I will add a edit: If you are not good at assembling things by feel, don't use one. For me they are very simple to check and use.

I think for me the problem was that with hard tight trail riding or town driving with lots of stop and go, on and off. Or full throttle to nothing all the time causes the adjuster to prematurely tighten. Where as the desert folks seem to be able to get much more for miles.

So far I have 3000 miles on the with the MCCT and have not needed to adjust it. I do need to check the vales again and will check it at that time. And that is my future plans to only check it when checking the valves every 3000 or so miles.

Be ready if you do use a MCCT, you will get jumped on by alot of people for being and idiot. I find I post very little on the facts I am getting because of that.
 
Let me just ask, (not argue). What does the MCCT have that the ACCT does not?
1) Is it the tension mechanism wearing out or the chain stretching?
2) Will you not get the same results, but have to do it by feel?
3) If it’s the chain that is stretching, It will need to be replaced regardless of what is keeping it tight. Am I wrong?
 
I believe that most of the fault with the ACCT is that at some time in the heat cycle it over tightens the chain. Thus causing excessive wear to the chain.

Most riders that seem to get good life from the chain with the ACCT.
Ride long times at set throttle positions, the engine goes through very few heat cycles.

The worst seems to be short town trips and on and off the throttle hard all the time. Lots of heat cycles. And lots of chances for the ACCT to get another notch.
I rode mine a few miles back and forth to work 2 trips a day. So it no more than got to temp and I would shut it off.

I feel if it lasts me 10,000 miles I will have gained on the deal.
At the rate mine was changing, at 3000 miles it would have needed to be done. So I was willing to try the MCCT. So far it is preforming like I expected.

Hope that gives you some idea of the decision making process I went through.

Lastly always rememer this with the MCCT,
If you are not good at assembling things by feel, don't use one.

What oil type / weight are you running?

What is your typical riding condition?

I use Golden spectro 4- semi synthetic 20-50 , change out every 600 miles. I ride 20% single track 30% open areas and 50% canyon carving with the street tires on. The chain stretch could be from my aggressive riding, not sure tho. Never had any problems with cam chain ware on any of my other bikes in the last 20 years.
 
Man I dunno...... I've checked Flying Trash Can's at 4000mi. and he doesn't baby this bike much, and he was at 4 clicks. I checked another buddy's at 3500mi. and this one has been over heated a few times and he was at 4 clicks. I've done mine at 2500mi., 4000mi., and now at 6000mi. and I've been at 5 clicks all the way through. Some guys (and gals) are getting less than 3000mi out of a chain...... It's a mystery to me......
 
For those of you that have changed out the cam chain, did you install new chain guides and replace the driven gears? Just trying to get a parts list going.

Did you get that impression from something that happened on Cafe Husky?

What is an APE and what does it stand for?
 
No mcct for the dohc Husky's? I will send them an email. I put 2 TT mcct's on our DRZ's. I didn't remove the valve covers. Just put them up on a stand in 5th gear, found compression stroke. Removed old, installed new finger tight and locked nut. Fired up and adjusted. The how to they have can scare people. :eek:
