hi and happy new year to everyone.
i have a t3 which has recently broken its very small gear lever butterfly return spring. im told its a big job to replace a $5 part.... the question is: has anyone done this on their bike and is it a difficult or relatively easy job? are there special tools needed for the job and if i m doing it, what other parts should i change also during the course of the job?

Gear lever return spring was the first 'big' job i did on a Guzzi. if you have reasonable spanner skills, some decent tools and take you time - several hours strip and rebuild, it is 'easily' doable. hardest part was getting the front frame bolt loose to crab the frame, this allows you to drop the box out. it is a pain to replace a small cheap part but it's what you have to do, no easier option.
there are lots of help online about crabbing the frame - her is a simple one

Not done the job but, given the gearbox needs to come out (and that it is 40+ years old) it is certainly worth checking the condition of the clutch whilst in there - be a shame to do the gearbox now and then have to do the same job again to change the clutch next year...

I did that job on my SPIII. I did manage to do it without removing the earbox complete, just managed to pull back the end cover enough to get the old spring out and new one in. Had to break the new gasket to get it in though. It all worked fine. I would not recommend that method in hindsight. But it can be done if you are desperate enough.

I found, years ago, in the UK NBS Nigel is a gearbox top bloke and will often have a service exchange gearbox my last one was rather well used when this spring broke and to be fair needed a refurb anyway, cost me £145 .....old gearbox in fully refurbished one out .... well worth it to me as the old one would have needed more than the spring i am sure ......but as you are not in the uk that one is not an option

Yes you have to watch for that, so I don't suggest it's done that way.

crabbing helps get to know your bike - but be careful taking the pin bolts out and in again off the the swing arm, they are very fine rhr3qfs and easily stripped

I assume that you wanted to hit the adjacent keys and type "threads"?
