Let me first change the pads, lube the calipers & check the air filter - then I'll think about the dyno run :)

May as well do an oil change and new plugs too.

Doing the oil on Sat anyway. I don't think I'll do the plugs. It's only 15k miles and they are a bitch to access.

if you really want to chase this few extra mpg


then do a full service on the bike yourself and make sure things are done right


I would look at removing that exup valve if your still suspect of it but remove it properly


then buy yourself a power commander and get the fueling set up right on a dyno


then after you have spent £700 chasing that few mpg keep the bike for ten years so that £700 pays for itself :lol:


seriously if a 600 cc bike is leaving you from a standing start your either shit or there is something wrong with the bike! only you can decide which :lol: but a 600 should not be leaving you

No he doesnt


He runs them on a car dyno with a homemade adaptor!


not the best set up IMO


if your going to get your bike on a dyno then use a bike specialist who knows the bikes :thumb:

Or the third option, the 600 rider is amazing at launches ;) After that Phil speeds past

Could be just that I need to hone my slipping technique on the R1 - I could definitely pull away faster on the R6 without a doubt. If I let the clutch out too quickly, I get that horrible clutch noise which I didn't get before (on the R6). Not sure if that's lubing or the difference between 600 & 1000?


Definitely not going to remap/power commander etc. As you suggest, just not worth it. Would be nice if it was just a case of changing air filter and suddenly everything is better... hmm...

what clutch sound :?


I have never had any clutch sound on any 1000cc I have ridden they either wheelie or stall :lol:


a power commander and remap is well worth every penny if you intend on keeping the bike


do a full service first including plugs and stick iridiums in


balance the throttle bodies too while you are in there although this will have no bearing on MPG

Yes.


Maybe the bike is so slow due to the fat oaf with a large frontal surface area who is riding it... :popcorn:

Yer there shouldnt be any noises from the clutch.

Is it loud enough to video?

It's loud enough for Alex to hear above both our loud exhausts...


I can try with a gopro and external mic I guess.

is this clutch sound all the time at idle and a rattle?


or just when you're setting off

If I set off and release the clutch too quickly. Unless I slip the clutch a little, there is a noticeable power dip. I *can* launch it, but it requires slipping.

For the fuelling, if I see you at a rideout I can have a pop on it and see if there's an issue. Ridden plenty of bikes of the same ilk, fireblade, Gixxer 1000, MV Agusta, HP4 etc so if there's a problem I can compare it with those. The Gixxer was a bit rough off the line, whereas the blade was smooth, but if there's an actual issue I'm usually good at picking up on them.


For the clutch, some of my past Honda's have done that rattle. Usually I let the clutch out and there's a brief deep sounding rattle, not a thrashing noise. Usually happened at low to medium revs with a high load on the clutch, which I think might just be an imperfect clutch shuddering under the torsional load you are putting through it.

Nice one, I'd appreciate that.


The clutch noise you described is spot on. Is it bad for the clutch life to hear that if it is as you believe?

the rattle is the buffer springs in the clutch basket

this will do it mostly with the clutch pulled in


and slight rattle with the clutch out is normal


the screeching noise is totally different

Normal it is then Stu - no noise when the clutch is pulled in. Only on a sudden "dump" I guess when the revs drop to 1.5-2k.
