gruet782 My k761 still reversed on front, no problems, no underwear skid marks passing semi's, gravel roads and rain no problem, no cupping, few thousand miles now...

The original K750 KLR front tire works quite well at speed on gravel, imo.
Well I guess one experimental "reversal" has been reversed. As of today.

The Mefo Explorer MFE99 does work better on gravelly roads according to the owner.
But, he thinks it 'might be cupping faster'.
I think he may have run lower pressure than I recommended for mostly asphalt use (Maybe his Gauge and My gauge don't agree? His tire had a 30 mile 'Hot' pressure of 29.5 psi. And it was 'pretty warm'!) with his weight and gear load.
But this was both of ours First Experience with Mefo Explorers.

So I dis-mounted and re-mounted and balanced for "free", as originally agreed.

gruet782 Caught in the rain today for about 50-60 miles, first time in a real rain since reversing the direction of my K761 front tire.
Standing water on the road, curving foothill roads, little interstate and my gravel road home.
Good spray off the side of the tire, no problems at all.

Tom Schmitz Paul,

I have been changing the rear 761s at 9,000 miles and the fronts at 18,000 miles.

My rear tire is near that point now; I'll be happy to cut it as you describe when I change it out.

It can be 'amazingly tough' to push a sharp knife thru a Worn-out/Bald Tire! Be careful.
I will do it if I remember.... LOL.
I can mount and balance also for free, I have a friend close with the equipment.

So far grip feels real good however from the recent snow storm there is still a lot of sand on the roads so I am cautious on cornering right now, however I am not out playing "Ricky Road-Racer", I save my fun for the dirt...

pdwestman Gordon,
I am extremely pleased to hear that installing the Kenda 761 Front tire in the '^' or backwards/upside-down direction allows it to work properly.

A pair of Kenda 761s are about the price of one Front Avon Gripster!
The question now is mileage / handling and grip of the Kenda 761s.
I have gotten over 15,000 miles from 2 different front Avon Gripsters.
I have gotten between 8,300 - 11,025 miles on 4 different Avon rear Gripsters.

Maybe you and Tom can make me and others a 'convert'.
I can mount and balance my own tires for 'free'. Other owners pay for this service, and the less frequent, 'the more appreciated', it seems.

gruet782 After about 400 miles since mounting my Kenda 761 front tire in the wrong direction and it runs great. All the wobble behind semi's and strong winds is gone, 65mph on the gravel road to my house is nothing.
I don't know if I would ever buy the 761 again but if I do I will mount exactly the same..

gruet782 I am lucky enough to have the use of a Coats tire changer, so 2 more changes today...

Put it back on correct direction... same problem, handles like sh$t

2nd and last time, wrong direction, new tube, handles great...

If I have to change a tire again I think I will throw-up..... lol

Tom Schmitz Paul,

On graded gravel roads with a solid base (like Soda Lake Road in Carizzo Plain) I have run at 45-60mph with no problems. Don't even bother to air down. They're fine.

Heavily graveled roads (like the roads around Mono Lake, which have natural alluvial gravel base that is loose halfway to China) it's hard to get the tire to plane out of the gravel (about 30mph) and then it's a squirrelly mess. Have to ride the shoulder.

Speed o worked fine, no damage.... I believe flip worked also..
I did check for play or any signs of obvious problems before removing wheel.

Gordon, That is great news to hear.

Now I would like to know if you or any other users of that tire (Kenda K761) can tell a difference in your bikes dirt or gravel handling habits?
But you may not have ridden enough dirty roads to tell us.

As to the speedometer drive, I purposely rotate the Gen 2 drive units to the 9:30 position. That makes a smoother routing of the cable, especially near full suspension travel.

Thank you for participating in this little experiment.
Paul

ps, Re-reading I see that I over-looked, "My gravel road feels a lot better also..." Thanks again.
