Honda Spree and Elite 50 Forums

I picked up a smokin deal on an 85 Tomos Bullet the other day. While it runs pretty good now after a few hours of cussing at the ignition system and *puke* Encarwi carb, it's shifting into second gear really late and chattering during the shift pretty bad. Then once second engages, this horrid(but not real loud) gear-whirring noise starts. My first guess was it was low on trans oil, so I put in the specified amount after draining out the old stuff(black and quite thin) of just some 10-30 so I could take it down the road. No change.

My question is, is there a specific type of oil to use? I've been told it calls for something like ATF4 with grit, but the oil I used I put in the specified 350mL per manual.

Anything else I can do to this thing to get a little more grunt out of it without buying parts? Already considering the BiTurbo pipe..

Oh yeah, and the speedo reports 37-39mph. Feels more like 35ish.

^^ here's the manual...
Sounds like you have some internal problems judging by your description....
The manual doesn't give you much info regarding the problem, but does confirm the 10-w-30 oil for trans is correct.
There are apparently two clutches, so the low-speed clutch is probably slipping.
The gear-whirring sound is probably a bearing that is going bad.
This is all just some guessing, but best I can do....
