WE’VE BEEN BUSY – WITH. THE. FOURTY. EIGHT!

Been a while since we have posted, but all in good reason. As the summer picks up, the workshop gets busy. We’ve appointed a new general manager, and also opened a suspension room, as well as a paintshop.

Nevertheless, with the date of our next show, the Hoddesdon Classic Show, http://hertfordshiresuperbikes.com/classicshow/ and https://www.facebook.com/events/660508590673301/ getting nearer, we decided to take the 48 out of retirement and get it running again.

You may have seen our 48 at shows, during the eBay stunt where it was up for sale; MCN reported it too!), after it went viral when it was displayed for the McLaren Employee 2013 show or simply at the workshop proudly sat next to the Guinness World Record Certificate. Here is a brief intro on it: http://hertfordshiresuperbikes.com/48cyl.shtml

Anyhow, there have been numerous videos of it running all over YouTube, from various Kawasaki Triples meets, but nothing recent.

In light of our upcoming classic show, in conjunction with the Borough of Broxbourne council, we got it running again (after 5 years), and filmed it for our internetters!

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!

Yes! A CBX1000 Pro Link in at Hertfordshire Superbikes?! Yeah!

Here at Hertfordshire Superbike Centre, we have all sorts of machines enter our doors.

Lately, we’ve had a CBX1000 Prolink (see pic below for a minter!).

Our CBX1000 seemed to be in decent nick for its age (30 years or so! older than me!), but simply wouldn’t start. Checking the obvious, we found it to be a faulty starter motor, which was quickly diagnosed and the problem resolved!

And this thing running.. Sounds SWEET! I think they made it to sound like a jet!

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.

P1080875

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

P1080877

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.

And we started off from the clutch side.

P1080880

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

P1080882

A closer look at the clutch side.

P1080890

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

P1080895

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

P1080903

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

P1080905

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

P1080921

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;

P1080920

Piston bores were fine,
P1080916

As was the top end and head, valves etc.
P1080915

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!
