My Valve Adjustment Story So Far: Could Use Some Advice?

[Birdy68]

I went with a sharpened, bent finishing nail. This and a magnet did the trick. Also rotating the bucket to where the dimple was on the inside of the head, where I could get at it, was the last hurdle.

Thanks for the insider tip! I'll be at that stage tonight...  :)

LATE last night I was able to pull the cover off and take the readings:




I believe that only the three Intake shims should be replaced...

So I'll be using a nail and magnet tonight to measure those shims  :lol:

That was nice worksheet, is it by any chance downloadable?

[Birdy68]

Hi harre,

I believe Mustang has a version also. But here is the one I created at work yesterday  :lol:  (I was bored...)

It's in the European size A4 too

Thanks, will come in handy.

Nice worksheet!

If your intakes are the problem, I wouldn't rotate the bucket dimple to the inside like I did because that won't help you. I had 2 exhaust valves out of spec and the radiator is in the way there.

Seems like it's unusual that I'm having to change exhaust valves, instead of intakes. I keep hearing that it's the intakes that are usually getting tighter. But the bike here is a 96 Triumph Sprint, not a Steamer. I'm going to do the steamer next.

Valve clearances have now been done....


BIG Thanks to you Nikolai for the 'Nail' tip.
And a SPECIAL thanks to Mustang for the excellent Shim Removal Tool.




So - here's my findings and the corrections I made if anyone's interested:


Yes - it is a new Worksheet. I found that I needed an area where I could write down the second readings after installing the replacement shim.
 :roll:

I've included this version below for those that would like it.
Feel free to use.

Wow, that was fast! Good work!

So the nail helped you? I'll say don't make the nail tip too sharp: it could break off while pulling the shim out.

I'm waiting for shims to come in the mail.

I'm kinda weirded out that I'm the only guy with exhaust valves that are out of spec.

would it make you feel any better if I said  I have only had to shim exhaust valves on the 95 tiger of mine once in 55,ooo miles and they were two exhaust valves ?

Thanks for the new worksheet!

I've had to reshim exhaust valves more than once.

Just lucky, I guess. :roll:

[Colonel Nikolai]

Makes me feel a little better. This bike - a 96 Sprint - has 45k on it right now. Maybe this is the time for it?

[Birdy68]

Well - fitted all parts back together yesterday and start the Tiger up. All sounded good!
After a short while (I let the oil circulate a minute or two) I twisted the throttle slightly.....

The RPM's sticked!! :shock:

Strange - as the throttle grip twists freely and springs back OK - No problem there.
BUT - the RPM's stay open and ever-so-slowly come back down... :?:

Obviously it's a mechanical problem.... So before I start stripping all back down to get to the carbs - does anyone have any tips / advice / hints I should look at.

Thanks in advance.

[Colonel Nikolai]

Throttle cable? It's really easy to hork the cable ( pinch or kink ) when you remove the carbs / airbox.

[Bixxer Bob]

NO offence Col Nick, but if it springs back ok it sounds like the linkage is working as it should as there's no spring in the twist grip.

Edit, just deleted the rest of this post, I'd gone into Girly mode (IACVs etc) :oops:

[Mustang]

make sure there is some free play in the cable at the twist grip end there is an adjuster there at the twist grip

make sure the cable is setting into the ferrule at the carbs properly

sync the carbs

adust the idle  screw

if the rpms hang high at like 2500 rpm and then slowly settle back down to 1500 by itself . If it is you may want to turn the idle mixture screws in 1/2 turn to a turn

[Colonel Nikolai]

NO offence Col Nick

none taken: you know more than I do!
