can't believe how good my mileage is By grocerygetter (Read 1,747 times)

Good catch on the damage before installing.
And nice that you had no trouble with a replacement.
Its disappointing enough when you are ready to make a repair and have a brand new defective part in your hand, and then the thought process starts wondering how easy this is going to be rectified.

Also good call leaving the jets that came in it as these replacements seem to be working well. Although it would be interesting to know what they are. And if in fact we are all getting the same jets for that matter. You know that 10 yr old kid in the factory is grabbing whatever they give him from a box full of jets.

BTW took the wife out for a 100 mile tour around the north end of the lake and thru the islands today.
It was hot today, 2 people on it, some good grades to go up. I honestly didn't expect to get into the 80mpg range today. Outside temp and 2 riders do show in performance.
GPS showed 96 miles. Took 1.229 gals to fill it back up in town.
No dead-on science to these numbers but that works out to 78mpg. I eyeball it to the same place in the filler neck best as possible. But really if you mess the numbers by a decimal place or two it does make a difference in the result.

I absolutely notice a mpg difference with outside temperature. And sitting in city traffic. Definitely doesn't like hot city driving. None of which I did today.

Rural drives in cooler temps that I've been doing alone around the lake feel like it can't run any better.

The main jet on my carb is a #107. This is a lean jet and could explain why the mileage figures are so good. However, this could also give poor performance and a hot running engine unless the carb calibration is very good. I did not check the needle valve setting or the pilot jet size.

Maybe these carbs are a better quality than the OEM types and they certainly are a good price.

I'm waiting for a little cooler stretch of weather to tackle the carb replacement.

Thanks for looking into the jet size.
Yes I believe someone dialed his setup in with an O2 sensor and he liked the 118 or was it 115?
I would take heed to the higher temp that this carb/jet may impose.
Many people south of New England tend to have over heating issues as it is. Even in the 80deg temps here there's a nice breeze often off the lake. Possibly more oxygen.

My performance seems to be good to decent. I'm sure different jetting and the sliders that I havent got to will net me something.
Yesterday with 2 riders against a gusty 30mph wind and up a good hill that causes my truck to gear down, i was able to hold 55mph with no issue. Had lots of throttle left.

On that heat note I keep looking into small car heater cores or add-on tranny coolers that can possibly fit into the space below the gas tank where there is currently a 'snaked' array of the lower rad hose with a coil-over spring.
If I find a heater core that can be retro fitted there it will be my next project, even though heat up here is rarely an issue. I'd just like to keep the engine cooler regardless. Runs better.
