Ticky Ticky... Is this cam bucket thrashing I hear?
« on: July 15, 2019, 10:37:06 PM »
Looking for insight. Getting a little noisier over there and it is consistent to the the rpm of the bike. If i rev it increases in speed and vise versa. It's become a cause of concern. Not sure how dire it is.

What year is your bike? Is it within the VIN range? How many miles on it?

See here for more info on the soft valve guide issue:

That looks like a 2014 Xc

It is the 2014 XC and is supposedly outside of the vin range.

I asked a friend of mine (service head in Triumph service here) - sent him the video link. That is a cause of concern, you're right. I've never heard a Tiger make that sound before.

My 2012 sounds like that sometimes and it had the head done. Almost at 35k miles  :027:

"sounds like a valve bucket" was the answer from the head mech at triumph here just based on the video

Hi, I have this sound after increasing the valve clearance to max. Yes, yes, I know, that was the advice of the local mechanics. Probably, that wasn't the best advice ...
2012 TEX- motor head replaced, timing - excellent ...
While I'm driving, I'm nervous about the sound, but the fuel consumption and traction are super ... I'm driving ...

The range of clearance (minimum to maximum) for the TEX valves is extremely small (0.05mm min to max). There is no way that the engine should sound any different if your current valve clearances fall within the specified range (exhaust: 0.275 to 0.325mm, intake: 0.10 to 0.15mm).

The original "cam bucket thrashing" issue is really a misnomer for the soft valve guide/head replacement issue in gen1 TEX bikes. The clattering is a result of worn valve guides which allowed the valves to become loose and close at an angle. In other words, if the valve guides are worn to the point where the valves are loose, you will get clattering noise even if the valves are adjusted to the proper clearances.

exhaust: 0.275 to 0.325mm... Exhaust- 0,32 tool in, 0,35 no. Intake- 0,12 in, 0,15 no.
This is a tip from non-English Triumph mechanics ... These are mechanics practicing on Japanese motorcycles.
  Valve spacing should be maximum ...
Oh yes, and I'm from a country that doesn't have triumph service
 The head is replaced unless the service documentation is incorrect ...
