Gear change clunky on 1995 T'bird

Question for the spanner experts. I've just got a 1995 Thunderbird 900 with 20k miles. Took it for a first ride today for an hour or so. Generally very happy. Pulls really well especially when wound up a bit.

However, the gear changes are very clunky, especially changing up. I only tried 1st to 4th, but all seem stiff. On changing up most times it takes two goes. I push up on the gear lever and it won't move, then I take the pressure off and try again and it changes up easily.

Also changing from neutral to first is very clunky and loud. I know this is common to some extent with many bikes, but seems worse with this bike.

Perhaps my technique, but worse than I've had on any other bike. The garage I bought it off claim to have done an oil and filter change.


Any advice appreciated. What should I check first?

First, does the clutch release correctly? (Can you push the bike in gear with the clutch pulled in? If it drags a lot more than in neutral, the clutch may be dragging.)

What type of oil did they use for the oil change? These bikes use a wet clutch and different oils, even different oils recommended for wet clutches, will often perform differently. Look for oils that carry the JASO-MA(#) rating. I've had good results with Shell Rotella T-6. It's marketed as a Diesel oil, but it used to carry a spark ignition rating and it meets the above spec. It's also a full synthetic and is readily available here in the colonies for a reasonable price. (Since it doesn't meet the more recent specs for cars they have dropped the "S" rating, probably for liability reasons.)

Lastly, the transmissions do tend to be clunky, but you shouldn't have to try to shift more than once per gear change.

Thanks John. Just tried that and it's a little harder to push the bike in gear with the clutch pulled in than in neutral. Does that mean the clutch lever needs adjusting? Or a problem with the clutch itself?

Hi, I am in same situation as you. First I have to overcome a certain resistance with clutch lever pressed in first gear, which then releases, then it is just a little harder than in neutral. But when in first gear with clutch pressed engine do not pull.
I hope someone knows what to do with it.

The clutch runs in an oil bath, so it's always going to be a little stiffer than in neutral, but if the bike doesn't creep forward when you hold the clutch in in gear then it's releasing OK.

OK. I know how it is when clutch do not release properly from my previous VT 600, when it was not adjusted right.
