Gearbox queries

[andcro]

Hi guys,

Well my TTSE finally arrived just before the weekend and I've christened it the Phantom. I've only had time for a quick ride of about 10 miles but I find the gearchange not so smooth and once in 5th and 6th I'm sure I can hear a whine from the gearbox - like a diff whine on the old cars. I had a quick search in the forum - but can't see any mention of this, so the question is - does this sound normal?

Thanks

Andy

The gear change not being smooth is probably just down to the pivot bolt/linkage seizing up, see the threads on 'gear lever' to get an idea on stripping/cleaning them.

How old is the Trophy and how many miles has it done ?

Gear changes, especially on NEW bikes, can take a while to quieten down as the parts bed in.

Some Owners have reported an improvement after changing the Engine Oil.

I find that the more I actively concentrate on changing gear smoothly, the "clonkier" it can be,
but if, for example, you are accelerating "briskly" and pre-load the gear pedal a little,
then just "blip" the clutch at the right time while momentarily rolling off the throttle,
the next gear just drops right in as smooth as anything ! 

The "Whining" noise could be from the Drive Shaft and transmission links.

Also try only pulling the clutch in 1/2 way. This seems to disconnect drive allow a smooth change as it keeps everything spinning. Works for me

Coconut - the bike has 24k miles on it and has "apparently" just been serviced as part of the purchase.

The whining noise starts as soon as I put it in to 5th and stays with 6th.

Silverstripes - Will go for another ride today and try different clutch techniques.

Earthman - the lever moves freely enough - but I'm wary of this problem so will strip, clean and lube.

Thanks for the tips fellas.

I just looked at the gearbox exploded parts diagram - it throws a spanner in the works with the problem being just isolated to 5th & 6th so it's as you guys say possibly shaft or just me being overly sensitive

Just took it out for another run on a quiet road - definitely a whine, but not just in the higher gears - just more evident then.

It doesn't sound shaft related - sounds more from the engine area.

Also noticed if at slow speed and in the wrong gear, it can sound like a bag of bolts, but I'm guessing that's just character

As for the gear change - great going up, needs more pressure than I'd expect going down - no difference when trying different clutch techniques or blipping the throttle.

I think I might run it up to the Triumph dealer for them to take it out - even if just for piece of mind.

From your use of the word "apparently",
I'd ask the Seller for proof that the Service was done ! 

It's a fairly Major Service at 20,000 miles,
including Valve & Timing Adjustments !
