If you had a 'L' shaped object, and that object could be slid through the inspection opening and used to lift the primary chain you would be able to see the relative movement of the 'L' shaped object in the inspection window thus indicating the movement of the chain. Hope this makes sense. The 'L' shaped piece could be made from lexan or steel rod with a 90 degree bend. Should'nt take long to knock one out. Big Dog

 

It shouldn't be that difficult to get two fingers in there and flop it around. And yes, it's just a "feel". The trick is to make sure all the slack is on one side of the chain and for inpection purposes that'll be the top. You're looking for about 3/4 of an inch of play

Thanks Bigdog.....I feel like a moron for not thinking of that. I knew there was a simple solution and I was just thinking too hard to come up with it!

No Problem. Glad to help where I can.

 

Re: primary chain

,,why isnt my chain stretching fx dean?

Unless you beat on your bike like I do mine, your primary chain shouldn't stretch much after break-in, much like your drive belt. Don't blow off the inspections at regular maintenance intervals though...better safe than sorry

I tried to check my chain on Saturday, and could
only remove two of those stupid TORX screws.
I rounded/ruined two cheapie TORX tools trying.
Ordered a good one from Snap-On, hope that will
work.

Any one replace those things with allen screws?

 

To be accurate on the primary chain, be sure and check it at more than one spot. Sometimes there is a bit of difference. I've seen more than one that was way too tight. Any adjustment should be done at the tightest spot on the chain. Remove plugs, jack rear end up, put bike in 5th gear and slowly roll engine to check.

Use never-seize on the chain insp cover bolts and the derby cover bolts. Remember they are T27. Water gets in behind the bolt head and interacts with steel bolt and aluminum covers. With never-seize on it, there will be no more problems.

I've got over 60K on my bike and only had to adjust the primary chain one time at the 1000 mile service but I also don't hot rod it. Normal use will not stretch it very much at all as long as it's lubed.

 

i am a pretty conservitive rider and i do check every 5k and at different spots,,guess i just had in mind that it was supposed to stretch ..like a drive chain,,i didnt do the 1k service ,,,i was beggining to wonder tho
thanks

 

Got my Snap-On T27 TORX and it did the trick.
I'm glad I checked, the chain was loose. I adjusted
it and used some anti-seize when I buttoned it up.

Good to go....

 

FWIW, Loose Chain Caused A Knocking...

My partner, who bought an '02 Fatboy, had a knocking in the primary at ~3,500 miles. It turned out to be the primary chain was loose (he had the 1,000 mile service by a Dealer).

Adjusted and OK now.

 

I had about the same situation as your partner, Mitch.
The 1000 mile done by a dealer- at about the 3000 miles
I could hear a noise from the primary side. Sure enough
the chain was loose. Adjusted it and no more noise, Mmmm..

 

hey guys i had the same isue my chain made noise at 2500 to 3000 miles after the dealer did the first service, adjusted the chain and it has not changed in the last 20,000 miles and i service it avery other oil change ande i change oil at 2500 miles. i be4leive in clean lubricants make the bike stay together and i can ride not fix.
