View Full Version : refill ratio

Hey Bats,

I recently bought a 2000 GPR. What a blast. :)

Anywho, I was wondering what the fill ratio might be on the gas vs. the oil tank. In other words - how many gas tank fulls should I expect to see for one oil tank full.

usually. when i did a wheelie and the premix was low. the refill light would come on. you can just keep it toped off.
a guess would be 5 tanks

yeah my light comes on with the tank full, which is why I'm currious about the ratio. Gives me an idea of how far I can go on an oil tank. For now I'm just checking it all the time.

can you see the oil tank under the teat or in that general area? if so and its clear. you can read it that way

yeah that is basically what I do. I pop open the "gas tank" and look inside to check the oil tank level. At some point once I get some docs on the machine I'll take the oil tank and sensor apart and check it out. Having rebuilt a Saab transmission I can't imagine that there is anything on this bike that I wouldn't be able to wrench once I had some decent intelligence on the issue. :)

Derbi Manuals & 6-Speed Manual (
Once you have these you won`t need a mechanic, these bikes are
easy to tune. Like a mountain bike with chainsaw engine...

Still don`t know where this "Teat" thing is located i`ll have to sit & think on it, lol.
