Explorer / Re: Transmission issue & Hello!
« Last post by AM407 on May 27, 2014, 02:00:43 AM »
Well, the saga continues...

Received all the parts and put the bike back together last week. With the bike on the stand and before the clutch went back in, I ran through all the gears a few times and she seemed to be shifting perfectly. Buttoned her back up and fired her up for a few trips up and down the alley. Got it up to fourth gear and everything was great.

So my wife and I head out for the weekend to finally go riding again. Had a couple hours of great singletrack and some hill climbs and the bike was fantastic.

Then we get to a gravel road and she hits fifth gear, no problem. Then sixth gear... and BAM!... rear wheel locks up instantly and bike comes to a skidding halt.  :(  Gearshift was stuck solid, but with a bit of wiggling managed to find a gear (2nd or 3rd?) for the long ride back.

So, just got it home and got it taken apart again. Surprisingly, all I found was a single dog tooth that had come off and was stuck to the drain plug. But it seems like the whole transmission is mis-aligned/out of whack, as nothing will spin more than 180 degrees in any gear. I'd have thought something was stuck in there, but it all looks clear.

So, time to source a new transmission and start the whole process over again.  ::)

See the little brass coloured knob? That allows the rear brake to actuate the clutch to any amount if you wish.

The reason is to keep from stalling the bike if just using the LHRB lever.
You can have it affect the clutch or not- quickly adjustable.

I can see many times where it would be nice.

I found out the rotor is different also.

I'll hold off for a bit (Ive ready spent a lot on goodies lately)- I managed to straighten the bracket.

I reckon the Explorer rear caliper is far too fierce and replacing it with a 280i item could be a good move...

That's an interesting bit of kit. I can understand what a hand operated rear brake does but how does it interact with the clutch? And why?
Any chance of a web link to Clake? I've Googled it and can't find anything.

Explorer / Clake II

I installed my Clake II.
left hand rear brake, spring assisted clutch and keeping the footbrake.

I've only used it a bit so,far, but I think it will be great.

The brake can can operate the clutch also if you want, to a varying amount.
I really like a LHRB, since I can keep my feet where I want them and my hips straight with the bike.

TR280i / Rear brake caliper

Does anyone have a picture of the TR rear brake caliper and mount?

It seems it is different than the Explorer, and I'm looking into alternatives since the mount on mine is bent and I can see the caliper flex. The explorer came with a 4 piston caliper- appears the same as the front.

I'm new to this and an old trials guy. I always dreamed of owning an MAR in the 1970-1973 models. I have been looking for one in excellent condition. To be honest I haven't seen any on ebay in awhile or for that matter any on any site I've looked at. Anyone have any suggestions or know someone looking to sell? I'm located in chicago area. .

I thought the fender may be too close, but I over 75 hours of trail riding (and 4 trials) I've yet to have any issue at all with it.
Even with really sticky mud I didn't have any sort of problem.
I do run the pressures low and perhaps that helps flick the  mud off?

My understanding is you shouldn't adjust the idle without setting the TPS.
  There is a new throttle body avaliable that solves that, but I don't know the price.

Trialsage-good to see you got on!
