From what I remember, Yamaha don't do a service kit and as the bush/seal sizes are odd, there are no off the shelf replacements available, so some machining is reguired to alter 'something' to take a different seal. Can't remember who told me this as it was a long time ago, so can't tell you who can do it unfortunately.

However, Nigel Brkett used to be able to supply a Boge rear shock for the TYZ at a reasonable price, so may be worth ringing him if no-one can advise where to get yours repaired.

There is a guy here in the states rebuilding shocks and he has rebuilt 2 for me over the last 2 years with excellent results. He says the shock seals leak because of nitrogen pressure loss in the shock. Apparently the seal needs the pressure to expand the seal against the shaft. The only time the seal needs replacing is when the shock shaft is scored or damaged. Usually there is some oil loss as a result of the pressure loss so the shock needs an overhaul but not necessarily a new seal. Good Luck.
