We have 2 high mileage champs, one with a 2002 (35k miles) and another with a 2000 (50k miles). Based on discussions, I think thermal cycling is responsible for accelerated wear then oil.

If you can, review your chart data and give me an estimate of your average trip length. And I'd count a trip with many short stops as one trip if you get back on it before if cools off.

Hi Ver,

Mine is an urban warrior. Average trip length is 10 miles. I ride year 'round here in Colorado Springs, so sometimes I'm sure the engine never gets fully warm when I take it out for just a short hop.

Also, for my chart data, the indication was None and I use 10W40 motor oil.

IHTH!

Mine is an '06 with 14,000 miles. Modified plunger done at 11,000. I bought the bike at 3,000 miles and the adjuster was out 17mm already. At 11,000 it was at 20.5mm, so I put Verslagen's modified plunger in.

hmmmm, we have always been told that most wear occurred at startup, and figuring in the heat cycle as a tangent off of that. Your theory does make sense.

That being said, most of my trips were 25+ to work with a good bit of miles put on just beating around. 100 or 2 in a day stopping, but never really letting it cool down much. The PO had a much longer commute to work (50+) if I recall correctly, for the first 4500 miles or so.

That seems counter to the amount of stretch on Betties chain.

quick acceleration definatively plays a role. I havent accually measured yet, but when replacing my clutch plates i took note that my essentally brand new chain (about 3k mi) was signifcantly "stretched". Id say 14-15mm out from an unused measurement of 8 or 9. Those 3k mi followed my performance mods and needless to say I gun it quite a bit...as in pretty much always.

14,5XX Miles (2nd Owner Since 5,0XX Miles)
17.5mm Extension, Intend to Install Verslavvy once available
Stock Adjuster
Oil: Rotella T Since Acquired
Riding: Short Commutes During College Years (5-10 mi) Otherwise Lettered Highway and Interstate on 10+ mi trips (65-75mph)
Aggressiveness: Moderate while ringing it out every few rides

My ride seems to be on the mark for reinforcing inspecting the tensioner at 15k, I inspected at 14.5k and I'm sitting .5k short of the recommended 18 mm limit.

WEAR, at start-up is attributed to oil pressure Not being there to protect rotating and sliding parts.
The chain gets tensioned when the cylinder gets taller from heat. If your tensioner just grabbed a tooth on the ratchet then when the cylinder gets hot and grows afew thousandths of an inch it pulls hard on the chain.
That's why the new modification of the added spring that lets the entire tensioner assembly scoot away from the crankshaft a bit helps.

I know it's been a while since any updates on here, but I figured I'd add my 2 cents.

1995
22K miles (probably more, speedo cable was gone when I bought it)
Tensioner at 18mm, seems to be stock
Chain & Sliders are in good shape
Unsure of oil type or riding style. I don't know the previous owner, got the bike through my usual mechanic. Figured I'd check it out while the bike was apart, rather than be surprised a few thousand miles from now.

Year: 2015
Mileage: 16,659
Old or new adjuster: Original
Plunger extension: 14.5mm
Chain stretch: Didn't check
Indications: No indicators - checked the tensioner during oil and filter change
Repair action taken (what did you replace): Oil and filter
Type of Oil? I was using a Motorex synthetic bike oil. I ran the oil low (it took 400mm to top it up) because I skipped a couple of services - long story. I am now using a Penrite product MC-4ST 10W-40 (100% PAO & ESTER)
Rider type: I accelerate hard and then cruise at the speed limit.
Where do you ride the most: Mixed; local jaunts, twisties, and highway. I ran the bike hard while re-jetting - testing acceleration, top speed etc.
Number of Previous Owners? 2; I bought the bike with 1500 kms on it.
