Further update on problem.

Whilst the anakee change solved 95% of the problem which was a vibration transmitting thru the bars it still did not totally solve the problem.

This progressively got worse and I suspected it may have something to do with the clutch. With the vibration getting worse again, it has been decided by the dealer to replace the clutch basket within the next two weeks. Will let you know if this totally solves the problem and brings the bike back to what is was like at 8000km.


Thanks Mick for the chain tension suggestion at 60mm on side-stand has improved the running with two-up.

Hi guys,

I may be little late coming in on this one but here goes....

i had similar problem, always around 3000 rpm, sounded like a woodpecker in the engine.

took it in, they agreed and took the engine apart but could find nothing wrong.

just suggested that one of the cam chain tensioners was modified on the later engines and that may be the cause.

Basically I have to live with it.

However... Like one of the earlier posts, if you ride in lower gears ( as advanced riders do ) then the bike is generally at higher revs. i found that when riding in this manner the bike is much smoother and the woodpecker has taken flight.

Regards.

Off topic but, advanced riders use higher gears not lower ones.

Yeah, and there's no need on a Triumph engine because it's not a weedy 600 Jap 4 down low. These guys are teaching people to rev the nuts off their engine and waste fuel needlessly. Fine on a race track but useless on the road. I've heard one say "you should keep the revs at around 7000". I'd love to see an "advance rider" riding a harley.

Anyway, the vibes you feel at 3000rpms is the drive chain resonating is sympathy with the engine firing strokes. I've had 2smoke trailies do the same thing. Nothing to worry about.

I've had the same problem on my '06 and it still drives me nuts. The bike was easily the smoothest thing I'd ever ridden when I took it home new. After about 5000 miles it started to get the trailing throttle buzz, most noticeable in 5th and 6th using even throttle on the freeway. On a trip over the summer it became much worse.

I've tried various things including slacking/tensioning the chain, adjusting the clutch cable, I even went so far as to put on a new chain and sprockets at 10,000 miles saving the old ones just in case. No improvement.

Since the vibes started I've fitted new Anakees front and rear, no effect.

I have noticed that if I pull in the clutch lever *just a little* while the vibes are heavy, just enough to take up the slack in the cable without actually disengaging/slipping the clutch (RPMs remain the same), the vibes almost totally disappear. I pulled off the clutch cover and had a look around at the plates, basket, pressure plate and actuating rod but nothing seemed out of sorts. The basket sorta felt like it had a tiny bit of radial play but so did a partially disassembled bike sitting right next to the Tiger, so I don't think that's it.

I wonder if it's a case of too much end float on the clutch shaft? Anyone know if this is even adjustable (engine strip)? Maybe a bummer bearing down in there somewhere? I've come to live with the vibes and maybe they've even gotten better, but I'd sure like to be rid of them.

On a possibly related note, shifting on my (religiously maintained) bike has definitely not improved with age and seems worse than ever, though it's kinda fun playing its little game. For a while.

Despite this, I sure love the bike!

One other thought would be unbalanced throttle bodies, I took the bike to the dealer at around 9,000 miles and asked for a check of that, was told to come back for the 12,000 mile service! Okay, you don't want my money then! Anybody do a throttle body sync at home? Do you need a Tuneboy or some kind of high-tech balancer? I can't really see how I'd run the thing with no tank on it, I guess I could rig up fuel lines and power, but I think the airbox has to come off also, doesn't it?

I understand Mike (TigerFox) is going to post after he's thoroughly tested out his Tiger after it has had the clutch basket changed. It is now been changed and from Mike's remarks the jury's still out on this, a lot of the vibration which had continued to develop has disappeared but not entirely. The bike is still not vibration free as it was when it had got to the 8000km mark.

In initially investigating the vibration the dealer loaded in fuel management update and slacken off the chain tension which made the bike run smoother at low speed in traffic but did nothing for the vibration. The front rotors/discs were also changed under warranty.

He's basically had two different vibrations develop, the first as posted, a delaminated front Anakee, co-inciding and which progressively got worse was the clutch fault.

He originally traded in an '05 Tiger last year for a late imported new '06 and these are basically the same bike but I believe the '05 was entirely trouble free.

Lube the chain.

TbirdNZ, the '06 has the 1050 crankcases, different gearbox and the backlash eliminator on the clutch........ not the same as the '05.

I have notice the exact same thing on my 2006. I also had an 05, which I now wish i had kept....
