Seeing as how the stock combination is tight as a drum, I thought using the aftermarket tensioner with its minimal adjustability just might be perfect along with the 26. If not I have a $200 paperweight.
 
If you machine a slot to one of the OE tensioner holes to adjust it for belt slack, I would suggest adding a set screw against the mounting stud to hold tension. I had trouble not being able to tighten the stock nuts enough to hold the adjustment. Adding the 5/16"-18 set screw was the trick:up:
 
I think Lunatic has it opposite. He's reliving tension on a stock set up for some reason, so the tensioner will just rock back to the loosest position of the holes he hogged out and stay there. Would work fine for that purpose.

I think with the sprockets you want to put on, the belt will be too loose and you will need to take up slack in the belt and fight to keep enough tension on it.
I've done that both with belts and chain conversions on Buells and haven't found the clamping force of the nut on the stud to be enough to hold proper tension on the belt or chain, even when over-torqued. That's why I recommended a mechanical, adjustable stop like a big set screw.
In this configuration it would be pointless to slot both holes and make the whole bracket wobbly. Just slot one and pivot on the other one.

YMMV, IMO, TL;DR, LOL
 
1/4" is quite a bit. That 27 might just work. It might also make my gearing for Sears Point unacceptable. As is I just bump the rev limiter in a couple of spots in 3rd. This back section is mostly uphill in 3rd. Turn 2, 3, 3a, 4.

....no set-screw required. only on here could it start a debate.

No debate here? "Would work fine for that purpose", if he wanted to loosen a stock set-up. BUT he's trying to tighten a non-stock set-up. You gotta read the whole thread my man...

Outthere ordered a 26T sprocket (Not stock 27). I have done the same thing and it made the belt way loose (IMO). I slotted the tensioner to act like an old V-belt adjustment and found it would loosen up no matter how tight I mounted it because there is clearance left in the slot when you are taking up slack instead of relieving slack like you did. My solution of the set screw worked perfectly at stock mounting bolt torque specs and was very easy to tighten to whatever you like to boot:up:.

With Lunatics solution to his opposite problem, the tensioner is held in place by the end of the slots he made, would not need a set screw. Happy now?:angel:
 
Like in this terrible pic of my last XB track bike. 'Murica:) Yes it's chain converted, but stock idler bracket.

I tried to edit it better, but I'm lame. See how the bottom nut is closer to the edge of the stock idler bracket, moving the bracket up not down.

New tires, (used almost every inch of the old ones), new bearings, new rotor, front and rear pads.

I decided to try the Diablo Corsa's instead of my favorite Conti-Sport-Attacks

Once I break in the Diablo's, I'll add my comments. Might be a week or so, since I am being paranoid about slippery tires... (not really an issue with the Conti's)
 
;)

Couldn't be happier.

My highly talented mechanic is jealous and wants a couple new rotors...

I did everything but the tire replacement and bearings. Easy Peasy.

Also gave me a chance to cleanup those dirty bits I could not reach with the wheels and skins on. Not a full cleaning as I ran out of time and HAD to ride today.

I still have a box of new parts for my S3T getting installed this weekend. Delving into replacing all the motor mount bushings but I need a new front motor/air cleaner mount since a previous mechanic cut mine to remove a broken exhaust stud, never thinking I'd go back to stock. :sorrow:
