Hi, I'm new today to the forum, so I apologise if this has been asked before. I have a 2004 Boxer cup Rep (red white blue) one, two things that have bothered me since new, it has now 4k on the clock, the vibration through the bars at between 70 to 80ish and a slight whine ( no not me LOL ) when slowing through the gears, took it back to S/port shortly after i got it, they assured me it was just a quirk of the bike, is there anything i can do about the vibration, as after 150 miles my hands are so dead I cant even cancel the indicators and is the whine a quirk, bike runs fine.

Welcome Keith, I think you'll find that the vibes are pretty std, that is until you junk the cat & fit a Y piece in it's place, that and after around 12k miles the motor starts to loosen up a bit. Good choice of bike though.
Whereabouts in Lancs are you? I'm in St Helens Meself.

Ive been riding an aprilia over the past couple of weeks, and have to admit getting back on the boxer is a bit of a shock regarding the vibes. Mine's been vibey ever since Ive had it though and im sure most of them are just the same.

Hello Keith and welcome to the madhouse.

The vibes, well you'll always have some it's just the nature of the beast I'm afraid but there are some things you can do to minimise them.

Firstly get a damn site more miles on the engine, that'll help immensely, usually around 12-15 K the vibes lessen and the oil consumption improves.

Second thing is vavle adjustment and throttle balancing, this should make apretty good difference.

One other thing 'search is your friend' for most queries, but don't be afraid to ask ! Just not oil or tyres

When did the grips change to the thinner ones. I think Gromit was trying to get hold of some older grips, as they are thicker, and he found on his new bike that the vibes were worse than on his previous incarnations...?

Is it possible to fit the old grips in place of the new ones?

Industrial white finger i remember it well!!!!,everything as above,fresh plugs,Twinmax to balance the injectors,Shell optimax,and cool weather!!!

And as already been said miles!!!! and lots of e'm,i'd say you've another 6,000 miles at least untill your sentence is over!!!

Grips changed in 2003. I've just received a new pair of the old 'ribbed' style grips* from Motorworks which I'll be fitting very soon. The new grips are far too thin for large hands which makes the bike uncomfortable.

*S(cough spit)C told me the old-style grips were no longer available btw

Must admit, of the 4(!) 11S's I've owned, this one's the smoothest so far and it only has 4.3k on the clock. It started off really rough but a couple of tankfuls of juice and some 'enthusiastic' use has made a huge difference to the motor. Changing to H-D 20w50 mineral oil has also smoothed it a tad. Over the last 1200 miles I've found it also ain't bothered about what petrol I put in it - Optimax/Ultimate/normal 95RON stuff doesn't make a jot of difference. Wondering if the twinspark motor is making better (or certainly more efficient) use of the fuel.

Autoexpress ran a comparison of the different fuels this week. In an engine without knock sensors, all the 97+ RON, premium products delivered less power. On their test Astra VTX (with knock detection), Optimax and Tesco 99 both delivered reasonable power increases. Interestingly, BP Ultimate delivered worse performance! They're blaming it on a "bad batch"!

A lot has to do with much 'feel' you get from the bike,mines like chalk and cheese between Optimax and anything else,but haveing said that so's my Tiger,when we went to NI a few weeks back filled it full of normal and regretted it within minutes of rideing it,found it even more pronouced when out on the motorway.

Lloyd reckons he can't tell the difference either,but he's more insulated than me!!!

Keith - the y-piece (or cat eliminator) is available from Laser, Zach or Remus. Costs itro 180-200 quid new but they occasionally pop up on ePay or in the bits for sale section on here.
