Hertfordshire Superbikes Launches on-line TV channel on YouTube

Hi ladies and gents!

As per the title, we have launched Herts Superbikes TV, as part of our YouTube channel.

Basically, it is a series of videos, to show our customers and the public the day-to-day happenings at a busy motorcycle workshop.

You get to see behind-the-scenes action, as well as the laughs and banter that goes on! You’ll also pick up tips and advice along the way!

We haven’t got professional video equipment, not are we professional videographers (give us a Ducati and we can work wonders, however!).

Check out the channel below!




Yamaha YZF R1 Engine rebuild with pictures, part 1 of 3

We have a Yamaha R1 in that was, unfortunately, run with little or no oil, as as we all know, it could cause catastrophic damage to the engine internals, as the oil lubricates all the internals.

This blog post is part 1 of three – as the project can be divided into three parts (and the blog posts will be divided likewise). Stage 1 is the disassembly, and diagnosis, Stage 2 is the actual repair and stage 3 assembly and testing. If we make other discoveries or realise the extent of damages are far worse than we imagined, this structure may have to change.

Firstly we went to get the bike on the bench and start stripping it down. The engine was not run after we had learnt that it had been ran with little or no oil, but we turned it by hand to check for strange noises, and indeed, it was a little rough and  sure enough, there was a knocking sound! Didn’t sound good at all.


First step was to turn the engine by hand to check for any potential damages. It was pretty rough and didn’t feel right.


We then proceeded to removal of the engine from the frame. Several skinned knuckles and some help from another technician and the heart of the beast was plucked from its torso!

The next few pictures show the engine disassembly, to look and see where the problem was.


Engine on the bench.


And we started off from the clutch side.


Proceeding onto the sump, to check for any lumps or debris caused by bits grinding or breaking off.


A closer look at the clutch side.


Removed the pump to check the gearbox for anything out of place.


We then went on to dismantle the crankcase upper and lower sections, to check the actual crankshaft itself.


Crankshaft removed, with bearing shells on the right hand side of the picture (on a shop towel).


The shells did look battered and abnormally worn. Along with the channels that the shells sit in. The crankshaft also had some damage too.


The pistons and conrods were, thankfully, saved. Had the engine been run for any longer, the build would have been taken to another level, of work, and expense!

We then checked over the rest of the parts, as below, and thankfully, nothing much to report here;


Piston bores were fine,

As was the top end and head, valves etc.

The  camshafts are another delicate part, and damages to these could be costly, and if gone unnoticed, it could really ruin your day! We removed these and checked for run-out and ensures all the cam lobes were smooth and as intended by the manufacturer.

The damaged crankshaft has been sent to a good friend of ours, and an expert with engine internals and engine building, for repair. We will post up part two when it arrives.

Take care for now!


Clean bike? Or can’t be bothered? It may just save your life

How many times has something like a split hose, broken chain, or other avoidable problem, come along when you least expect it? Miles away from home. During the dark hours. In the rain.. (you get the picture).

Now, cleaning your motorcycle wont only keep these avoidable issues at bay, it will also keep your bike looking good.

There are many on-line tutorials on cleaning motorcycles, so I wont go too much into it, but a quick Google search will bring you step-by-step guides. In a nutshell, be sure to use bike specific cleaner, rubber-safe cleaner for rubber parts, plastic-safe cleaner for plastic and so on. Most commercial bike cleaning solutions nowadays are safe to use all over the bike and are formulated as such. Wax on the paintwork will also keep it looking clean for longer and protects the paintwork.

Whilst you’re cleaning, it’s the perfect time for the real topic I want to write about:-

Preventative Maintenance

Preventative maintenance is maintenance carried out to prevent problems. A good example is your motorcycle chain. As the chain wears, it stretches and must be kept at a correct tension setting. To loose and it may come off, too tight and it may snap as you go over speed humps or potholes. The correct tension also helps increase its life. Now, ensuring it is always set at the correct tension will prevent it being too loose or too tight. Similarly, frequently checking brake pads is also a good idea, so as you don’t realise you got no brake pad life left all of a sudden. The same goes for clutch/throttle or any control cables. Checking them often could avoid that moment when you’re miles away from home, about to downshift, and realise the you press the lever and feel no resistance, and you somehow fluke it to a stop only to figure that your clutch cable has snapped.

Whilst you are washing your bike, it is a perfect time to carry out essential checks and preventative maintenance. Below you will find a list of things that are frequently checked, and I recommend for you to check. I may have missed something, so feel free to comment or get in touch for additions or amendments.

  • All lights, signals and horn working (including electrical switchgear – brake light switches, clutch switches and so on)
  • Tyres: wear, condition and pressure
  • Wheels: condition
  • Grips, handlebar, pegs all stable and not loose
  • Mirrors, fairing and all bodywork secure
  • Brake pads and discs
  • Chain and sprockets – clean and lube chain, adjust if necessary
  • Bearings – May need a friend help with these:
    • Wheel bearings, check wheels for sideways movement by tugging along the top and bottom from either side of the bike, with the wheel off the floor
    • Steering, push and pull bottom of forks (with front wheel off the floor using a stand that doesn’t hold it from the forks or headstock). Also, ensure that the steering movement is smooth with no knocks or notches.
    • Swingarm, it helps to have the rear wheel off the floor but isn’t necessary. Check for unusual side-to-side movement of the swingarm. The only way the swingarm should move is up and down (to compensate for speed humps and potholes, of course!)
  • Front forks, compress them a few times, then check to make sure that they aren’t leaking any oil and compress the front forks to see if the suspension works. Also ensure that it is a smooth movement with no nasty sounds.
  • Rear shock(s), press down on the back of the motorcycle to ensure that the rear suspensions works and the bike come up again. Also ensure that it is a smooth movement with no nasty sounds.
  • Rubber hoses/fluid pipes/brake hoses can perish over time if they are rubber. Certain metals can rust though too, so be sure to check over all of them. Even a tiny hairline crack can and will expand, so be sure to get it looked at quickly.

Preventative maintenance is that little extra that bikers should put in, to avoid big unexpected bills and odd breakdowns. Regular checks and greasing the right bits will keep your bike looking clean, feeling clean, and riding well. Ride a well maintained bike, your life depends on it.

We can do the above for you, as well as servicing and MoTs.

Ride safe,


Off-roading in Hertfordshire or London?

Hi guys and girls, another post today  following the earlier instructional on how to change engine oil and replace the filter on your motorcycle.


As many of you know, off road motorcycle riding, on an amateur level, is becoming a declining sector in the motorcycle world. This is due to many reasons; the green-lane closures is part of them.

As many of you are aware, we have recently taken on a new manager by the name of José Teto. He has many titles under his belt for off-roading and powersports (jet-skiing!). You can see his intro video over on our YouTube channel.

Being an off-road legend, he knows all about the trials and enduro rides (having competed in many on a pro level), so feel free to come down and have a chat with him!

Since José’s arrival, we also cater to the off-road and motocross sector, whether you race, ride or just potter around off-road.

We are also happy to carry out bike set-ups for long distance enduro rides!

Get the word out, and let’s collectively liven up the off-roading in Herts and London, and look forward to the coming summer!
