Hello again. I have a 1972 triumph tiger 650 with a 5 speed transmission. It locked up many years ago and a friend tried to rebuild it with used parts. Some of the gears may not be correct and whait I need is engineers drawings for the 5 speed transmission so I can tell which gear or shifting fork to replace. I have stabbed the gears 4 times and it will go into some gears but not others. I have inspected all parts for damage and can find none??? Is there anyone out there that can lead me to technical information on this transmissiopn or engineers drawings I suspect I have a wrong gear or shifting fork---Thanks again and I would appreciate any help

I recommend you ask those questions over on the BritBike website Triumph Bulletin Board?: http://forum.britbike.com/

As you are likely to get much more "Triumph" help there. Or at least, you could PM/email member "Ron - in California" at BritBike, as he appears to be very knowledgeable about the differences between the Triumph 5-speed gears, as the very early 5-speed cluster could be rather fragile (especially 2nd. gear) and a certain number of the parts were changed for '73-on, and shouldn't be mixed together?

Just to leave no (simple) stone unturned, are you turning the gearshafts (motor running or manually) while trying to shift? If not, may be nothing wrong with the gearbox, it simply won't engage dogs properly without moving the gearshafts.

Apologies if this seems remedial as that's not the intent, just don't want you to be frustrated chasing a possibly non-existent problem.

Good luck.
