Bigbore SRX gas milage

[srxxx86]

what are you bender/hauck/cpr guys gettin for MPG on your BB srx? I'm gettin 13-14. Just curious, thanks

 

[cacsrx1]

Didnt notice much change from stock.

 

[terry]

What Big Bore are you runnin?

 

[pro116]

Guy's with cpr bb's told me there getting 15mpg

 

[yamaholic22]

Yea downhill with the wind at their back

 

[cacsrx1]

They might not get quite 15 MPG but most if not all the "big twins" will need gas before U.

 

[pro116]

Yamahaulic why do you say that?They actually run a little leaner jetting than stock.

 

[HyperMax]

Yea, what pro116 said....

 

[yamaholic22]

ok its possible, but not probable

 

[shortstop20]

They still might get better gas mileage than the "bigger twins", but you can't tell me that a big-bore SRX is getting the same MPG as a stock SRX. Maybe I'm just ignorant but I don't believe that. If that's true, I should've big-bored mine a long time ago.

Shortstop "they are jetted leaner"

I don't know where you guys ride or at what elevation. At sea level my cpr 780 does no better than 8 mpg. My plugs are cardboard color and cannot go very much leaner. Maybe a little? This is with head mod and bored carbs. It does haul *** though !!!

 

[pro116]

Mac is that a viper or srx your talking about there not even close in gas milage.

 

[yamaholic22]

It is a viper

My 800 SRX was not even close to stock jetting. If it was I would have burned it on the first ride out.

 

[77-SRX]

I have a Hauck 780 SRX. Not quite as good as stock on fuel but still very good. It does as well as any two stoke I run with and better than most.

Years ago, I bored a 1994 yamaha 600 twin to a 700. Not only did it run a bunch stronger than stock, it did it on a little less fuel.
