Hi all, so after sorting the breather hose problem the bike feels more responsive and sounds like it is breathing a bit better!!! So this brings me to another couple of points that i would now like to address, My bike is only averaging about 120 miles on a tank, is this right? I know it is an older bike (1998) with around 42k on it, but from reading reports it would suggest it should do more? Any suggestions? Also with regard to the Divvy's top speed, it seems to top out on a flat straight (Privately owned off course) at about 95mph, is this right for a 600? Thanks all in advance.

You should be seeing around 115 to 120 on the clock of your divvy if it's in good nick engine-wise.Can't comment on MPG cos it's so long since I had one, but 120 miles to reserve does sound a little low.

Saw 124 indicated on my old D6 once, with a gale blowing up my a*se  , 110 would be more realistic I guess. Expected around 150 miles to reserve too, yours sounds thirsty, balancing the carbs would help. |

Both my D's would only see about 110 / 112, indicated. And I'm only lickle  . Reserve was generally closer to 150/160 than 120 though  . |

Is it restricted?
I sometimes only get 125 (to reserve) out of my 1995 D6 on motorways, cruising at 80. Typically I usually get 150 to reserve. Be interesting to see if my new zorst improves that. My first D6, a 1998, I used to get 180 to reserve consistently.

restricted 1995 D6, 110 indicated (107 according to Mrs Sat-nav) all on private roads of course  i get anything between 145 to 170 till reserve, lots of short journey's kill the MPG, i get better MPG hooning round country lanes than i do sitting at a constant 75-ish on the motorway. Flymo |

Mine tops out around 120 indicated, and 180-190 before reserve, that's 55-60 mpg. Yours got a leak or summat?!
Standard except Remus straight thru stainless system, run mostly up and down the motorway.
Is it possible the speedo is misreading, because both your readings are about 25% under.

Resetting the TPS, fitting new spark plugs and fixing a carb air leak seriously improved the MPG when I had a D600.

Aside of any carb/spark etc. probs you should get 150+ depending on your riding style.
As for speed that's very individual. It will only be best if everything's going for you (plugs, carbs, wind, down hill etc, your weight, speedo accuracy and honesty!)
More than a ton though for sure, all being at least equal.

Don't know what mines doing to the gallon at the mo. Had the same tank full of fuel in it for about 1 year? Do you reckon thats good running?? LOL. JK. I used to get around 130 before reserve and thats doing around 6 mile journeys to work.
Have seen the speedo around 120mph before, but, if I remember rightly, once at around 110 it went flat as a fart and slooooooooowly crept up beyond that. Hope to have mine back on the road soon .....

Well, i have a Nexxus straight through exhaust on it, i don't think it is restricted, looking at some pics on here of just under the carb ports would suggest mine isn't. Unless there is any other way of restricting it? I mainly do short trips of around 25-30k just to work and back so that would explain mpg a bit more, I'm doing a run from Oxford to Great Yarmouth soon though so will look at it then. So the top end, what to do? I think I'll get a friend to balance the carbs (as suggested, thanks) then I'm planning on getting the valve clearances done, so i guess I'll see what that does!! Thanks for all your comments. Most appreciated.

The nexxus exhaust will not make any difference whatsoever to the engine performance - they're designed to match the std exhaust and are very restrictive (like the std exhaust)

I have 93 600 with 16000 on the clock.
I also get about 120 ish miles to a tank when keeping to about 80 ish on motorways.
But keeping it down to about 60 ish I can get to nearly 170 miles to a tank.
I think getting the carbs balanced might help my bike a bit more.

On my 97 600 I get about 42mpg & can touch 100mph.
I know the exhaust is blowing a little from a bodged fix which I'll address this weekend & I'm pretty hefty for a poor divvy (15 stone) but I'd expect a little better performance, esp as I had the carbs tuned & sparks changed recently.
I guess she's just getting on a bit but I try to look after the old girl

I normally get 150 or so miles to reserve, and an indicated 120mph out of my 94 D6, but I'm only little Charlie  |

Hi all, thanks for all your feedback and suggestions. So i did a nice long run over the weekend, about 80 miles each way, and the fuel didn't run out, so obviously not liking the short journeys, which i suppose is fair!!! As for the top end, i got the calculator out and did some maths and it turns out the previous owner wasn't very good with the application of the sticker on the speedo! Where the Mph sticker said 90 it wasn't correctly lined up with the proper spaces on the kph clocks below!!! Ok yeah should of looked at that before maybe!!! Lol, oh well all seems fine now, and it appears to be doing about 110-115!!! Which is obviously a lot better!!! Thanks again everyone |

KPH to MPH... Divide by 8 then multiply by 5.
50 = 30
120 = 75
The 600 I had once showed 120 on the speedo and averaged about 55mpg. But on one slow run in snow and slush I only got 130 miles before the tank ran dry. It usualy went for 160 between fills and 180 to bone dry.

Blimey, all this talk of 120 on a D6 worries me I 'bottled' it on mine at around 90 |

Resetting the TPS, fitting new spark plugs and fixing a carb air leak seriously improved the MPG when I had a D600. On this very bike im averaing about 160miles per tank around town and riding in a high revving manour. I've achieved 220miles out of a single tank full and expect 250 would be possible if i REALLY tried. Although i darnt because my reserve doesnt actually reserve me any fuel! Daves brother, Graham reported fuel consumption at best of 65mpg before i bought the bike. On the note of speed I've seen 100mph on the bikes speedo (Closer to 90mph on the digital speedo) but mine is restricted. |

I can get up to 120 easily and managed 125 flat on tank but vibration made me easy back.
On a long trip at cruising speed I managed to get up to 198 before reserve, but normally around 150 to reserve.
I did have to add a in-line fuel shut off valve between the tap and filter, as I think my tap is defective and fuel would seep into carbs when ideal for long period of time, causing the fuel to evaporate in carbs and so give me less mileage to my pounds.
Maybe your taps defective too? and getting a replacement might be a bit steep, but a separate shut off valve solves that problem.

I used to get around 180 miles to reserve but it has dropped a bit now, whether that's because my riding style has changed (I find I use a lot more revs these days) or with issues with the bike I'm not sure. I think that the carbs need balancing to be honest.

I usually got about 160 miles before reserve on both my divvies in normal use. On the old one, that was somewhat sensitive to speed. A long motorway journey at 90mph would see that range drop to 120-ish, so if you are testing your bikes top end extensively that might have an effect.
Haven't done any long, fast journeys on the new one, and never tried flat out on either.

Make sure all four choke plungers are moving. When even one sticks open the fuel consumption suffers badly.

My D6 has 135K on the clock (I'm a courier) and still gives me 150+ miles to reserve on the motorway at 80-85mph. Round London stop start get 120/30 miles to reserve. Best i've had outta d6 is 130mph indicated and still going - but had to lie on the tank with feet on the rear pegs ;D. It's actually quite comfortable if you have a 500+ mile round trip to do and get a numb a*se |

Does anyone know if a sizable difference in performance should be expected between the half faired divvy 600 and the naked 600N version? MPG wise I'm getting 53MPG running around locally, assuming the speedo is accurate, which i think is good. Speedwise, if I lie on the tank and really wring its neck, it will only just barely touch the ton. Its hard work really. Also, unless my speedo in inaccurate, everyone round my local area only seem to drive at 25mph in 30 zones, so is it my speedo at fault? And, the bike vibrates like billio. We're all familiar with the 4000RPM buzz, but mine is getting worse to the point of being unrideable. Vibes start at 3500RPM and are pretty much there all the way to the top. I don't think the motor is in a bad way. its done 47K, just been serviced, doesn't burn or drop any oil at all, mechaniclly quiet apart from clutch rattle. MPG is fine. Any thoughts anyone?

I have a 92 600S and last tank I had was about 140 to reserve. Just passed 10,000 on the clock.
I do have a question tho. I am running at about 5k to 5.5k RPM for 65mph on the hwy on 6th gear. Is it normal?

There is little difference between the S and N, just a tooth difference on the rear sprocket allowing more pull in higher gears as the N has more wind resistance I believe. MPG will be roughly the same unless you hover at 7k and +. Vibe problem seems abnormal. It should smooth out approaching 5k. It should pass the ton with 'reasonable' ease and by what you say your speedo is reading 5mph slow perhaps. Otherwise the rest seems normal. |

, 110 would be more realistic I guess.
