After looking at those rebuild pics, I'm not even sure I want to ask my grade-school questions. That's just awesome.


My XR is starting to leak from the cam chain tensioner; bad O-ring. I think if I can pull it out just a half inch or so, I can get the new O-ring on or silicone caulk it enough to call it good.

Can I pull out the tensioner a little safely without opening up the head? If so, what's the preferred method?

You've only got to pull off the rocker box.

only going from memory but you can make a little tool to keep tension
on the camchain without having to remove the heads

it's been a long time since I did this so I did a quick search and found this
http://www.thumpertalk.com/topic/688...ionertutorial/

if you look at the third pic down you can see a small hole in the top of the tensioner
assembly,here you can make a small tool right angle in shape that will fit into the
hole and rest against the cylinder head holding the tensioner in the relaxed position

I actually made one out of the end of an old car aerial years ago

any of you guys using these fancy clutch perches and lever assemblies with
the bearings in the lever pivot? (eg works connection)

$100 for perch and lever seems fairly expensive but obviously they are top
end equipment,would be interested to hear peoples experiences

I have one of those TM flat slide carbs. Been sitting in the box on the shelf for 20+ years. Tried it and went back to stock.

A little wrenching during our Alaska spring snow....

-NEW LED flushmount signals. No more bustin' them off during an oopsie BTW I've never felt the need to blurr out my plate.


-New Kush Sprocket (slightly modified inner diameter to fit my 88) The bolt holes didn't need anything.


-View of countershaft sprocket after 8K+ mostly road miles without any cush hub or drive. NOT BAD if I do say so myself

_Finally the view of the XR's Only case guard after my chain came apart at 60 MPH......It did what it was supposed to do!


More to follow...

More work on the ole' 88

-First a new rechargeable battery with pigtails for the charger. Now when the toggle switch on the BD kit is ON the tail light is actually lit up WITHOUT the motor running!! Who knew




-Next a little needed grinding of the snail axle adjusters, might be time for some new ones. These are pretty toasted in the 20-15 range (I have not ground that area out yet, but it's pretty worn..)



That is all for now, carry on!

I fitted one to a previous XR after reading it can help with the cough/stall
(as can removing the auto decomp) and found it to be ok,nothing miraculous.

What made you change back to stock Steve ?
