They are both DOT. Also Kenda Parker DT have them DOT in both sizes (80/100-21 & 90/100-21) the 90/100-21 is a bad ass tire (Kenda Parker) it worked great in mud, sand or loose gravel.

I couldn't really tell what Inroads was concerned about as all these tires fit a DRZ just fine as you indicate. Lots of room up there to mount any of them. Perhaps he believes that he needs the exact same size that the factory put on.He doesn't as we know.Lots of choices.

my manual says 80/100-21.
Try this one it's an agressive Enduro tire and dot as well.

Thank you for taking the time to do your video, well done,easy to follow and informative.
On your other you tube video about your new camera I was impressed with the sound quality, what setup as far as the mic goes do you have, it was very clear with very little wind noise.

I'm not sure how good this picture is going to show up... I guess how big it will be but here it is. You can see how the left one has a groove in it.

Well, it looks like the one valve was a bit more than .004" out! I hope there wasn't another decimal on the bill behind the valve! Thanks for the pic.

Yours were damaged... TOCs valves are quite possibly stuffed too due to being run out of spec for FKHL... but the blanket application of your experience is misleading.

For others the valves might just be due for an adjustment. From my experience this seems to come due at around 30,000km.
There is a small amount of seat erosion which will account for a tightening of clearances where the seats are wearing faster than the tappets - situation normal. This does not mean that the valves are spent.
Good to see some humour

Either way your speedo/odo combo will be off about 10% anyway(optimistic).
Isn't the odometer able to be calibrated to remedy this ?

The seat is harder than the valve. If the adjustment has gone so far out of spec as to cause starting problems then it's a good bet that the valve is worn.

Km just saying if it were my head I'd rebuild it.

Ive got an audio technica ATR3350 mic plugged into the camera and the mic piece in the front of the helmet mouth piece. the sound was awful without the external mic, even going slow all you hear is the windnoise. Makes the exhaust noise much better too.

If you look at my 1st vid, new tyres required, thats the internal mic.
bought the atr3350 straight after hearing that :)

Recalibrated my roadie computer for wheel size, multiply by 2.5, divide by pie, add two something...


And it works ! Tracked todays commute with the phones gps to confirm the indicated speed on the bike speedometer. Looks like I'm 1% low, so ill recalibrate it again to set it 10% high, and give me some wiggle room from johnny law. :)

Offset for wheel calibration (stock trail wings) was 2163.3815mm. (Kind of a log)


I have enough room for my phone/gps/waterproof thing in the drz's old speedometer location. Brackets are silly easy. Prolly make a dash like mills to keep hands off of things.

some pics to compare gps to the wireless data. distance, average speed, and max/actual speed are very close. once it quits raining i'll take it up to 100 (or the limiter) for a few minutes to see how bad the deviance gets.

fun :)

GPS vs bicycle speedo comaprison:

Just had a look the ACCT, It's all the way in! I guess that explains the noise! The round nubby bit at the end of the arm had a shallow wear mark in it, should I consider replacing the chain guide as well?

Since it's pinned in place, I was thinking I could just machine a longer nub for now to get some tension back!
I know, Probably not a good Idea stretching the chain even further...

It looks like I might take this one to a mechanic. Not too sureI want to attempt a cam chain swap in one weekend...I've heard horror stories about people breaking off clutch baskets when they didn't have the proper tool! At least I could get the valves adjusted at the same time.... $$$ but less hassle

We've done a little work with Co-Cr face welded valves so out of necessity have some idea of seat (and OEM valve) composition and characteristics in these engines... and the results might surprise you.

Your comments have not been exclusive to TOC's head... The problem is that any time something is said you repeat yourself as if you're trying to force the point and you're generalising to the point that the novice is going to be thinking that when the valves are out of spec they automatically require replacement... which is simply not true.


PS. The longer explanation with more information was hosed by login and I'll be buggered if I am going to retype it.
For everyone's sake I hope he adjusts the valves so we can see the outcome first hand. He said it was his daily driver right? If so we should see the results in a week or two.

There she be, the fully extended yet still functioning ACCT.

IMG_0973

I have to ask, does anyone know how far the MCCT's reach is or how far is safe?? I joked earlier about making a longer contact piece for the end of my ACCT to get a few more miles out of the chain, but if it's actually feasible to do that, I would in a flash!

There's the wear mark I spoke of earlier. Normal?
