fuel tank capacity

Just wondering if anyone knows the exact capacity of the roughhouse 50 fuel tank. My owners manual isn't for my exact model and all the models listed are in liters.

I think the Roughhouse is basically the PGO PMX-50. Lemme guess, you have the almost useless but slightly engertaining manual for the Black Cat? Anyway, I the capacity is supposed to be just over 1.25 gallons. I've never put more than .8 in at a time. My gas gauge always tells me I'm almost on empty, and then I look and have 1/3 tank left. I have all the body panels off at the moment and looked for a sticker or marking of some kind on the gas tank, but there didn't appear to be indication of the capacity anywhere.

just a word of warning....
the Rattlers (50 & 110cc) seem to have a problem with vapor lock when you fill them ALL the way to the top -
when this happens, they are hard to start & ocassionally stall until you use up some gas - happened to my 50
there is a post about it some place in this forum.
dont know for sure if the black cats & rough houses have that problem or not...

I've not run into that problem at all. I use the kickstand and not the center stand when filling up. I fill up to the bottom of the rim. The tank never gets 100% full, but I never accidentally overfill it either.

There is a post on yahoo group on how to cure the vapor lock problem, pictures are included as well. I rarely overfill, unless I am using a plastic fuel jug. Then for some reason I always overfill it, so I typically leave the gas lid slightly ajar and this allows air flow into the tank. I am planning on doing the fix, so that I can completely top off my tank when I have longer rides planned.

I'll be doing that mod shortly - I caught the gas dripping out of the charcoal cannister while it was sitting in the shed.

Yep, I have the Black Cat manual...entertaining to say the least. I don't think it was ever checked for spelling or grammar, or it was poorly translated...anyway, I guess I just fill it almost full. Thanks everyone for the input.

BTW just got 100 miles on my Roughhouse...having sooo much fun!

I just noticed that my manual states "Tank Capacity: 5.1 Liter", which is approx. 1.35 gallons
