Air temps and top speed. Any relation??

- Summerai - Christine L /

Here is what im pushin.

-Stock E50 internals.

-Opened up the transfers along

with the exhaust ports a tad.

-Bored out the intake tube a bunch.

-High comp head.

-16x36 gears.

-Deristricted Estoril.

-Foam filter.

-78 jet.

I only hit 35mph gps with the

temp being in the low 30's.

I was hoping to hit around 40.

Maybe hope for warmer

weather and then tune the bitch?

Would that help?

Re: Air temps and top speed. Any relation??

What size carb? If it's a 12 bing, it doesn't matter if u bored out your intake. Also check for airleaks. A 78 jet seems a lil big for your setup.

Re: Air temps and top speed. Any relation??

how much do you weigh?

Re: Air temps and top speed. Any relation??

its been my experience that colder air is denser and thus you run leaner. i always jet rich for daytime so my bike runs perfect for bandit barhopping cooooool summer nights.

run out of gas. its a gas

hog man. yeah! so its

43 this morning still 35ish

on the top end. my face is

red!

Re: Air temps and top speed. Any relation??

well i would do the fine tuning when the temp is at 70-75. this way when the temp goes down colder than 60 i can put in a hoter plug, and when the temp goes past 80 i can run a colder plug

WHISKEY BIZ!!!

Drew, you have a number 3 cylinder, 2 hp high torque I believe. Open transfer also. How did your plug chop go? Did you check that yet? You are looking for a coacoa brown color to a regular coffee color. Black is too rich, white/grey is dangerously lean.

i didnt chop the plug yet but

i did take it off and looked at it

and it looked like a perfect cup

coffee with cream. a little

on the dark side but hey

with a 78 jet thats expected right?

Re: Air temps and top speed. Any relation??

Colder air is more dense, which would allow more gas to be used in the mixture. So in theory, you'd have more power in colder temperatures. You probably won't notice much of a difference...other than freezing your ass off ha. But it's always a good idea to use a bigger jet for colder temperatures.

Re: Air temps and top speed. Any relation??

My two-stroke motorbike (a Puch twingle) runs stronger and faster in the cold. It is also easier to set the idle correctly in the winter.

My problem is that plug chops in summer and winter look basically identical. WTF?

Re: Air temps and top speed. Any relation??

The difference is not really that great, twingle. The only time I have noticed is when it's <30 out and I ride my old Yamaha, it will run better with a little choke on all the time. Anything over 30, though, and it makes no difference other than a slightly longer warmup time.

My Benelli would do that too, though I didnt know til it warmed up as I only got it riding in January. But it made more power when it was warmer out, so I upjetted 2 sizes and it rides better all around. 2 jet sizes would probably be unnoticeable on a plug chop. I'd upjet the twingle a tad.

Re: Air temps and top speed. Any relation??

but it works and i dont have to sit there wasting time retuning a pefectly tuned carb when i can be riding in any weather.
