I've got a better question, why is this question in the Chevy venture forum ?
.035 gap
There isn't an 850 venture. Only a 1200 and 1300.
The Yamaha Venture was manufactured between the years 1983 and 1993. This motorcycle was produced in two forms, the Mk1 and Mk2. The Yamaha Venture was brought back in 1999 and renamed the Royal Star Venture.
100% Synthetic any major brand.
According to the owners manual, 1.9quarts.
I'm not sure, but if you go to venturerider.org, you can find a lot of info. Someone there will probably have that answer. Tell 'em 86er sent you! I ride an 86 Venture.
Depends on what model and where you live? Mopeds are worth less in more rural areas and worth the most in any city...in excellent condition...Yamaha chappy- 500-1200$, Yamaha qt50 200-750$, Yamaha Towny 400-900$, Yamaha champ 500-1200$, the more rust and the more plastic the bike has on it the less its worth...
So what, exactly, is the question? I have changed the oil in this bike, so what is it you want to know?
Should be around 3.2 Liters, if the same as the 1200's.
1983 and 84, 19.9 oz. per leg....... per manual.
