Title: Negative Clearance-Shims
Post by: threepot on March 11, 2014, 10:41:36 PM
It refers to my Super3. Sorry to post it here,but tried Triumphrat :icon_frown: Just some advice needed please. I checked the clearances recently. All Exhaust seemed ok,but on 4 Inlets I couldn't get a feeler in. And the other 2 were .07  .08
Am I right in thinking the best way to approach this is with the valve tool,and tackle each one individually? By buying the thinnest shim avail,then replacing the shim already in and taking a reading accordingly?

a good rule of thumb when you have zero clearance is to drop 3 sizes and be prepared to still reshim . 3 sizes will usually get you in the ballpark and you can at least get a reading .
if all six are out pull the cam its faster

Thanks Mustang. I'll come back to you on that. Maybe I have a 'soft' head :icon_frown: Maybe I should open a new thread on this?> But want to pick your brains again..I put a new set of pads in the rear on the Tiger earlier,but have spent most of the day trying to bleed it! I can get fluid to flow ok,but can't seem to build up enough pressure to close pads onto disc :icon_scratch: Could the master cyl be faulty? Thanks.

Threepot,

Why do you need to bleed when you've only changed the pads?

Anyway, I've had probs doing that in the past. I've found the halfords £5 bleed tool helps quite alot, still requires quite a bit of pumping though. If it still doesn't bleed properly then it's prob the master cyl seal. Not done the rear but front was easy enough as long as you've got some internal circlip pliers.

I had to swap the caliper from my Daytona. The slide pins had seized on the Tiger. Another bit of lack of maintenance by PO. Have tried the bleed kit valve,and a small length of pipe from nipple into a container of fluid,so it doesn't suck air back. That method normally works straight away :icon_scratch: I have read that placing the caliper higher than the reservoir helps? will try that tomorrow.

Just dont open the bleed valve to much and attach a tranparant hose on the bleed valve. Its only a 5 to 10minute job

And the seized pins are common on the rear caliper, not necessarily neglect by the PO.  There's a couple of different approaches for fixing them if you search for them.

A friend of mine from the National Chopper Club gave me good advice on caliper bleeding. Remove the caliper from the bracket and hold it with the nipple vertical, i.e. top dead centre, then bleed it. I had a problem bleeding mine, I did this and out popped a couple of little bubbles, problem all sorted.

Hanging the calipers up does help as Geoff says, patience really helps too  :icon_rolleyes:

Sprint manufacturing sell stainless sliding pins, new rubber boots is a good idea as they tend to go soft and lose the seal on the pins. Fit them into the caliper with some Girling red grease and use some Lithium based grease inside the rubber, it doesn't tend to dry up/harden like organic greases.

Thanks guys,going to try later.

Sorted. Took caliper off and left it suspended above the reservoir overnight,with the bleed nipple out.Did the job :thumbsup

Thanks for sharing  :icon_razz: wouldn't like to give us a tanking at rugby as well would you  :icon_rolleyes:

What sort of price were the Kyoto's, I've just paid out 24 quid a set for EBC's  :icon_cry:

I bought EBC pads to match the EBC discs I fitted after the OE warped.  I hate them; they've always felt glazed since day one, but am unsure what to replace them with as I've done over 60k with EBCs on the 'Bird with no problems at all.

Go figure, cos I can't.......

You need to thank Mr Hogg for that.

Didn't know what to do saturday - rideout or an all day rugby fest. Rugby won - there'll be more sunny days - hopefully.

I made the most of the good weather. Our loss to England took the shine off the rugby :icon_frown: But a smile out on the bike.. :icon_smile:

I did both, rode the Tiger to Twickenham and watched the rugger  :wheel, cracking day out well worth the effort

Where did you park the bike then? Somewhere safe away from the pubs presumably.

Nah, nice thing about the bike is you can park in the stadium car park. Since the bike section is right by the security firms tea hut nobody touches them.
