450T fork oil

[noser9]

Gentlemen, I have been searching on here, my Clymer, and even called the dealer and stumped them. I have an '82 GS450T that was my first bike and I have been rebuilding it as a cafe for the past couple months. Well I replaced the fork seals last night and was going to fill the oil and I can not find the capacity for the T model. The Clymer seems to have every other conceivable model but the T. The only thing I can think of is the T is generic and it is actually a TZ, a TXZ, or a TXD. They all have significantly different fork oil levels too. Is this the case? If so, how do I figure out which T model I have? Thanks!

A TXD would be an 83 model. The TZ and TXZ are 82 models. The Z denotes an 82, the D denotes an 83. I'm not sure on the differences between the TZ and TXZ.

Hmm...well that helps...but still the difference between the TZ (181 cc) TXZ (143 cc) is still pretty significant. Can anyone narrow this down a bit further? Thanks,

Tom

I agree. Perhaps it is embedded in the ID number on the bike (it is usually on the steering stem)?
Usually the feature set of the bike makes the difference (wheels, bars, seat, etc.) I looked at both forks and brake systems, and there was no discernable difference.

As long as the damper rods are covered, the amount of oil is not going to effect damping. What the oil does effect is how much air is compressed inside the forks. I'd go with the larger quantity since the springs tend to be a weak on GS bikes.
