Whilst I agree that if a person is not competent then they should leave it to those that are BUT

I have been in and round the motor industry most of my life and I can categorically tell you that dealer workshops are the worst when it comes to cutting corners and using substandard people and methods inthe guise of factory trained techs.

For a time I worked as a tyre "techician"by the end of my first day of training I realised that I knew as much if not more about bike and car tyres than the instructor (not trucks, that's another skillset altogether)

Basically the tyre shops only aim is to sell you the tyres with the biggest profit margin, fit them in the shortest time, upsell you some service or product you don't need then move on to the next punter, The actual quality of the work is a long way down their list of priorities.

Which is why

my wheels are cleaned of rubber on the bead shoulders before every fitting, and cleaned of weights, dirt and adhesive of course

the wheels (plus valves are then balanced sans tyres to establish the true heavy spot (if there is one)

The tyre is then fitted accordingly, if there are no balance marks on the tyre I'll check balance and if needed slide the tyre on the rim to get a better balance

Only once I've got it close that way will I use weights..

Show me a tyre shop that will willingly do that!

the same slapdash applies to workshops in my experience...someone on here recently had a gearbox killed because the monkey in the shop did't re-fill the box ..Boys it not hard..pour 2 measures into 2 jugs, 240ml and 800ml....if one still has oil in it you've not topped up the component.

I do the same with engine oil, I have a 5L container marked for "with and without filter" changes ...Simply fill it to the mark you require and then no matter how many interruptions you get you'll not over or underfill your engine

As along distance bike rider, I can and do ride for 10 or more hours some days...

... Here's my top tip for preventing SBS (Sore Butt Syndrome)

Change your underwear for lycra shorts...not the cycling ones with the foam and chamois just the tight fitting lycra ones (or cut out the chamois pad from cycling shorts.)

A pair of these under your ordinary riding pants will transform your "personal" comfort.

my experience of brembo brakes is this

Over time water and road salt/dirt/etc settles under the the outer brake seal. Once there the salt corrodes the brake caliper slightly the crystals grow, causing the outer seal to tighten against the brake piston.

The first evidence of this on the front will be unevenly worn pads as one piston will drag/bind more than the others

The same applies ( the corrosion problem) to the rear but the single side wear on the rear is more do do with bad lubrication of the slider pins

Best course of action is

Buy some red rubber grease http://www.redrubbergrease.com/ and a scriber as in the pic a Brake piston removing tool ..... I have the blue handled type in this link http://www.bikerstoolbox.co.uk/.../Brake_Service_Tools.html

a. front. Pump your pistons out as far as you dare on both calipers, top up your master cylinder if you need to. use a pair of old pads to stop the pistons coming out fully just yet.

You'll see that they don't come out evenly, one or more will be binding in the bore.this is exactly what I mentioned above as a symptom

b. Now is the time to get brave and disconnect the caliper at the Banjo union on the brake pipe, be ready for fluid loss, it is VERY DAMAGING TO PAINT

Now you need to gently but firmly push ONE piston back into the bore and use the tool inside the piston opposite to get it out...if you are VERY carefull you can use pipe grips and a rag or a strip if hard rubber as protection and grab the outside of the piston...do it this way at your own risk!

Once out use the straight end of the scriber to get under the outer seal and gently ease it out A close inspection will reveal all manner of dirt and crap on the back of it, give the seal a good clean and set it aside

Using the right angle of the Scriber (I have blunted mine into a scraper blade for this very job) run it around the seal groove in the caliper and you'll feel it go from smooth to rough, rough is where the corrosion is, at the gravitational bottom of the caliper.

Scrape out all the corrosion, clean out the bore (an airline is ideal but a clean rag can do it if you are carefull. lube the seal with RRG and re-install

Inspect the piston, clean off rubber residue from the outer edge (I use GT85 for that) is there is corrosion damage to the outer edge it's not a big deal as this part is exposed to the elements in any case so a touch up with fine wet and dry should suffice...if the piston is badly corroded where it passes through the inner seal it's time for new pistons.

Assuming the pistons are OK lube with RRG and reinstall....a paint dot on the caliper will remind you where you are at should you get disturbed

Repeat for the other pistons and the other caliper, re-assemble and bleed the brakes....prepare to be amazed at how powerful the brakes are!

To bring the other pistons forward you can use an airline (once the first piston is back in place) BUT you need to realise that the newly lubed piston will move first so you'll need to hold back the pistons you don't want moving or the piston removing tool

Rears are similar but being a one sided caliper you can pump them out without too much difficulty, remember to keep them even.

In all cases remove and renovate ONE piston at a time to prevent mixing up seals as the bore sizes differ

KB7 Filtering for Bikers

According to my bike cop friend the police view is that it is all about speed differential.....for example

traffic doing 15 mph...you filtering at 20 to 25mph OK, you filtering at 50 not ok

In my job as a bike courier I filter for much of the time and my rule is 20 mph max difference, that gives me enough time to scrub off the 20 mph if someones does a quick lane change.....I always ride with headlights on and some high viz. .... in very heavy or grossly unaware traffic (such as holidaymakers, people going to events etc) I'll use main beam and have my thumb hovering over the horn button

Also people are odd when filtering...some won't go between two vehicles, they wait until there is just one to pass...why,? that one is the one who will change lanes into the gap

Also creeping past a line of traffic on a single carriageway hugging the white line...why do that ? get out as wide as you can, well into the other lane if it is free, you'll then have some time to react to other drivers actions and plenty of time to tuck back alongside or behind someone when you need to

What amazes me is the bikers who will sit in a stationery queue or not drop in behind people like me who are by definition cutting a swathe through the traffic that they could easily occupy!

Clutch cable adjustment R1100RT

These clutches need freeplay at the handlebars or they will slip and wear out very quickly, so here is how you set the free play correctly.

Remove the rear wheel and the plastic side panels

undo the clutch lever lock nut* at the back of the gearbox and then wind the adjuster bolt out a couple of turns, you'll now have loads of slack at the bars

* I use a long socket on a universal joint on a long extension bar to get at the adjuster from the left rear. It can be done from the right but not with my big hands.

Back at the bars, screw the adjuster out until you have around 12mm of thread showing

Now here's where having a helper is handy....

Go back to the gearbox end and screw the adjuster in until your helper confirms there is around 6mm of freeplay at the handlebar end

Next get your helper (or use a zip tie) to hold the clutch lever tight up to the handlebar grip...this will prevent the rear adjuster moving as you re-tighten the lock nut, it only need a decent nip not a squillion Nm

Wheel on, side panels on, test ride and use the bar adjuster to fine tune your freeplay for optimum gear shifting. Every gearbox will have a different sweet spot for free play...too much and it will crunch into gear, too little and it will do the same so experiment until you get it right BUT always have some free play, I'd say 4mm was the minimum for a long lived clutch disc

NB #1 in an ideal world a conscientious owner would disassemble all the mechanisms and grease all the pivots and oil the cable while they are at it.... I do this once a year and I have a spare cable zip tied to my working one so I can do a relatively quick change on the side of the road if needed

NB#2 these cables are in two parts, an inner and an outer cable, IF you feel a click at the lever and gain a lot of free play at the bars it means your outer has started to let go...the inner will hang on for quite a while so there is no excuse for getting stranded with a broken cable

Oil level checking Oilheads (all)

These engines can hide oil like you would not believe possible, especially in the oil cooler as it has a thermostatic valve to aid quick warm up, the downside of this valve is that if you don't have the engine fully hot, then the valve closes before the oil cooler is fully drained into the sump for checking

The result is that you look at the window, see the oil below the centre line and top it up not realising there is up to another 1.25 litre hiding in the oil cooler and oil lines...then you get over filling problems such as oil in the airbox as the crankcase breather blows this excess out.

So here is how I do it for oil changes and oil level checks...

Bring the bike into the work area good and hot, now I mean really HOT like after a good fast run of 30 or more miles (not just up to temp showing 5 bars on a notoriously cheap and unreliable temp gauge)

Park the bike on the side stand for 20 minutes at least, this aids oil cooler emptying because the angle of the machine means the cooler is also angled down also.

Then put the machine on the centre stand for another 20 minutes (or longer)...it's a good point proving exercise to lie down beside the bike with a flashlight on the window as soon as you get it on the centre stand and you will actually see the oil level rise as the other oil chambers drain into the sump

After the second 20 minutes you should be seeing a fairly true oil level, I leave mine over night as a matter of course.

The oil should be in the centre of the window, bear in mind that from bottom to top of the window is only 500ml or 1 pint.

Now you can do your top up and I only top up with no more than 200ml at a time (usually just 100ml as my highest mileage bike uses 100ml per 1000 miles) and then wait for it to register on the window usually within 5 minutes, it has a fairly tortuous route to follow.

For best results only top up to the centre line and not above, this will give you the smoothest running as the camshaft sprocket and chain will only be dipping into the oil by 10mm or so rather than thrashing it around like a magimix on steroids when overfilled.

As a point to consider at an oil change....if you think your level is OK and when you drain your oil you only get 2.5 litres out then there is still 1.25 litres hiding in there somewhere, usually in the oil cooler because you didn't drain it hot enough or for long enough

My oil change method is as above and I always leave the bike overnight with sump plug out and the filter out

NB to avoid the horrible death rattle you get when you first start the engine with your newly changed oil and filter, spend 5 minutes filling your filter before you screw it on.

So there you have it, 3.5L without a filter change or 3.75L with one using good old 20/50 but done using the above method and you should be fine...My high miler is getting close to 270,000 miles on this method so I'm pretty sure it works.
