Project Resurrection

[The Lone Rider]

I dunno...

I've looked in the service manual and the tensioner is on the outside of each horizontal pair, and looks a little bit like one of those electronic thermometers you give kids. Has two bolts each side, and one on the top down the middle, and a gasket.

Part number 6 & 7 in this

Though I look at it now.. the service manual calls those the tensioners. The parts fiche calls them the lifters and 4 & 5 are the lifters.


I'm guessing parts 6 & 7 must have a spring in it, that pushes down on parts 4 & 5?


I haven't had a look at the bike really.. I'm unprepared as I have my bike lift in pieces to modify it to take longer & heavier bikes.

Ah the delights of overhead cams...

I think you're onto it re the tensioners - I don't know about Hondas version but some I've seen have hydraulicly adjusted tensioners fed off oil-pressure.

Otherwise yeah, a coil spring inside those gizmos.

Why? What do Harleys have? I've only ever worked on Japanese bikes - they seem fairly fluid to work on, for the most part. Especially if you can sucker someone into helping to hold things while you dismantle.

parts 4 and 5 are the tensioners, but 6 and 7 are the bits that will have let go should that be the problem. They come out easy, and you'll be able to tell straight away if one is buggered.

Harley's have push rods. It is a SHIT system, stick with the jappa.

With hydraulic lifters (think of them as a form of tensioner).

The last Harley I had to adjust them on was my '81 Sporty, it had solid lifters, easy-as to adjust too.

Shit system? - maybe to you but to me their lack of need of maintanance suits me just fine.

I only said it to get you to bite, but I have remembered you only wind up, instead of getting wound up.

Push rods work fine, as long as revs aren't the goal.

And roller rockers are roller rockers, the adjustment is the same essentially for OHC and push rods.

[The Lone Rider]

Ah yeah I'm familiar with push rods, just thought there might be more to it.

I thought factory Harleys had solid and non-adjustable push rods? And if you change the tappets, you need to put in adjustable push rods.

Anyway, new tensioner is about $75 plus GST... and a 2-3 week wait

And I can't get in to pay for it until Wednesday, and have to pay for it before it gets ordered.


There goes my trip to Omaru. Hoping I can still get it to a bike show 2 weeks into Sep though.

You have made sure, that the tensioners are the actual problem aye?

I ask, because on my old VF a noise very akin to a noisy tapit was actually a loose cam sproket. Imagine how much fun I had once those little bolts came out.

Push-rod flex sucks, that's why they went to the twin cams.


Parts 6/7 are the bits you're wanting to remove

Remove the valve cover and check the chains, if loose do this:
If not, I just wrote all this for nothing
Undo the central bolt first (carefully, there's a spring in there)
Then the two outer bolts.
Take note of how everything goes
Pull the spring out
Clean everything
Check both springs side by side
Clean everything again
Make sure the little pokey-outey (very technical terms) bits are able to push out, if ratcheting type, make sure they're not retracting


Once you clean everything a third time, re-install them with the two outer bolts, put teh spring in, tighten the central bolt over the srping.
Once that's done, wind the motor over by hand a few times (three should do it) to make sure they're working

Check tension on the chains

Sure it might suck for some - but as I'm pootling along at under 3,000rpm most of the time I doubt it's a problem to me...

Bonus!
Those tensioners suck don't they......

June 2008 - had new cam chain put in. Most likely be the tensioner.

3000rpm? I don't have a tach on either bike...
Anyway, everyone knows you need 200hp or the latest supersport, otherwise you're just a try hard wanker who doesn't know fuck about shit.

Well having only 65hp at least now I know what sort of street-cred I have!
