Re: fuel ratio
There is no way to know easily. Optimum air to fuel ratio for performance is 14 to 1 but economy is about 18 to 1. But without expensive equipment there is no way to tell what an individual engines fuel to air ratio is.

I suspect Bear knew that this question was NOT about AIR to fuel ratio.

That seems dangerous to me.
What carb size and jetting are you using?

Re: fuel ratio
24oko 48-122 now. Did not have the time to check for the jetting yet.
I think 32:1 is too much. Way too much smoke . Should be good for a racing setup but i am using the scooter for street riding.
Plus 50:1 is what the guys at VT recommended... Remember that Castor oil is very high performance. I would go 32:1 only if i am using some cheap stuff..

Re: fuel ratio
castor 927, recommed 25:1 to 32:1 .
50:1 to 32:1 need to retune jets on pilot and main.
You may not be aware of oil brands are not same premix ratio as 32:1
Some oils or are thick or thin.

Re: fuel ratio
I don't get it. Why are you using premix if your Elite has an oil pump? It's not a chainsaw.veedubh20 wrote:castor 927, recommed 25:1 to 32:1

Re: fuel ratio
all my bikes have oil pumps removed and i run premix, bear disagrees with this but o well lol... and some ppl add extra oil to tank and run oil pump for big bores......JJ Joseph wrote:I don't get it.

Re: fuel ratio
I disagree with removing the perfectly good and functioning oil pump just because you want to run extra oil. Just add a smidgen of oil to the gas to bolster the oil/fuel ratio rather than have to carry a lot of extra oil to run without a pump. I do agree with "add extra oil to tank and run oil pump for big bores......".fastplastic wrote:all my bikes have oil pumps removed and i run premix, bear disagrees with this but o well lol... and some ppl add extra oil to tank and run oil pump for big bores......JJ Joseph wrote:I don't get it.

Re: fuel ratio
The factory spree pump supplies somewhere in the 70:1 range I like my 32:1 smoker, but there will never be agreement on anything to do with lubrication. Between 30:1 and 50:1 seems to be the usual range, although there are alot of variables in play.
