ok so i went through the tutorial i ahve done all of stuff except for the new o-rings. made the mistake of thinking the ones that were in there were ok, and i will redo the fuel level check as well as reset the float level after i get my hands on a micrometer like the one he has in the tutorial

Let me interrupt to finish this off. Didn't want to Hijack tc862011's main thread/help, but wanted to learn from the feet of the masters

You are under the impression that you don't have to worry about jetting because you have CV-type carbs?

Yes, from what I've read and talking to others, I understood that I didn't need to rejet my carbs

How stock is your 850? Stock airbox or pods? Stock exhaust or a header?

Everything on the engine and fuel delivery system is stock.

This is why I come here


Please carry on with tc862011's thread. I'll take my punishment in a different thread.

Been through my carbs 4x in a month, new boots, o-rings, etc. but best I've gotten is 30 mpg @ 25-33% throttle (5.5k - 6k in 5th, flat slab on the interstate)sometimes worse, like 22 mpg. [Actually looked at it. 22 happens at 50-75%]

i dont mind the hijack what ever helps me will eventually help other people. i have alot of post throughout these forums not because i am having trouble with my bike but because i am a firm believer in asking as many questions as possible, the more answers i get the more i know

i finally got down to business today and did a mapped trip of 50 miles after i filled the tank and then i refilled the tank after the 50 miles. the math is saying just under 35mpg for my little gs550. is that about right or is that low. i am not lugging the engine the rpms is usually floating around 5-6 unless i am getting on her, then i am shifting right around the 9.5-10, i know the more throttle you use the more gas you are using. this is just a curious question. its not bad mileage compared to my minivan (that i hate driving).

My precious get upwards of 50 MPG Imperial
what that is in US can be found in an online calculator.

You must drive fast?

I don't know what mine is getting right now, but now that I have the stock exhaust on, carbs synched, and replaced all the o-rings (carb boot and inside the carbs) it is running a lot better and getting WAY better mileage. I'll have to calculate that out at some point.

[tc862011]

the only thing i have to do at this point is get new o rings and resync, while i am at it i will check the fuel level

[Toasty]

It should definitely be getting better mpg then that, I get 45mpg even if I'm flogging it and cruising at 75+ on the freeway. If I try I'll get 50+ (slow acceleration, 65 on the freeway) and this is with my bike not running right.

Are you filling to the exact same level every time you fill up. With the bike on the sidestand, fill to the bottom of the spout in the tank neck. Putting in small amounts of fuel, if you fill a couple of tenths higher and show 1.5 gallons instead of 1.3, it can make a significant difference in how you mpg works out.

The best way is to check it over about 10 fill-ups or so. Just record the starting mileage (odometer reading). Don't worry about the gallons on the starting fill-up, but record the next 10 or so fill-ups. On the tenth fill-up, note the odometer reading, subtract the starting reading. Total the gallons used, divide that into the miles travelled.

One nice thing about doing it that way is that only the first and last fill-ups need to be filled to the same exact amount. Any, or all, of the others can be as partial a fill as you want.

I was never under 50 mpg on my 550, no matter how I abused it. The 1100G is always 45 or so.

Same here, my 1100 gets 44 regularly, I have to really abuse it to get down near 40 even.

[tc862011]

Do o-rings rreally affect that much. And one day i rant the tank from full to empty and got 160 which equaled to around 40 mpg.
