Omnia Racing Headlamps... Cool Quality.

A BIG thumbs up!
I saw a CBR600 street fighter doing the rounds on one of the forums lately and, to be fair, it was a nice build. What really stood out for me was the headlamp — not in the "cheap, Chinese, badly-finished rubbish" type of way, but more "Buy Me Now! I am the quality you look for" — so I asked the owner of the bike where I could get one. 

As he looked at me, I could see his face contorted with pained expression. He gave a quick glance over his shoulders to check for eavesdroppers nearby, and he slowly whispered the words Omnia Racing... I looked behind me, was about to ask more, but he was gone.

So I started looking online. Based in Italy, with an impressive website full of expensive bike exotica, they also had an eBay store and I found just the unit to set off my GSX in a way that would somehow complement the odd-shaped ESD tank, along with my crudely knocked together tailpiece. Sort of.

Frayed Clutch Cables, And Making New Ones.

When you alter anything from standard...
Inevitably something must change with it. The clutch cable was way too long since I've dropped the handlebars down, and although I'd managed to 'lose' some of its length, it wasn't quite right. 

But it worked; until it frayed. So I bought a kit to make a custom one myself. 

Having seen the job done by Gordon at Lucas Motorcycles, Ross-on-Wye loads of times over the years, I figured I knew all the tricks of the trade. Whenever I had a cable issue on my bikes as a kid, I'd be straight up the dual-carriageway to Ross and he'd make one for about ten quid. Bargain, and that was at any time up until 9.00pm everyday of the week... the guy was a legend!

So if you have an issue with cable length, an odd bike or the original part is too expensive, take a look on eBay and check out the kits available. This one came from the UK and is a quality bit of kit, nylon lined for smoother action, oo'er missus.

DANGER! Scared Of Using Engine Flush?

Skeptical, or concerned?

You will find different opinions on using engine flush from every mechanic out there. Some say never use it no matter what. Others put it in at every oil change.

So why the difference in opinion? What are the pros and cons?

Valvoline detergent-based engine flush.

Greasing The Suzuki Speedo Drive.

Funnily enough... grease dries out and goes hard after thirty years of getting mashed in a worm drive, but how do you get the speedo drive apart without ruining the seal? Once they're put together, it's nigh on impossible to remove it — and you can't buy the drive complete now, let alone get the right seal! 

So, after a lot of messing around with a spare one I have, I decided to have a stab at getting it apart with minimal damage. I came to the conclusion that a 2.5mm hole drilled through the body of the drive itself would allow access for a small punch to tap out the seal. If all goes to plan, a small dab of silicone in the hole will seal it up once finished. Job jobbed.

Symptoms.
Just turning the tabbed washer will tell you how bad it is. If it stops, gets stuck and generally feels tight, it needs to be stripped, cleaned and greased. Leave it and the tabbed washer will fail, maybe even the worm drive and gear itself. The drive in my ESD has had the tabs brazed back on at some stage. And this spare drive has quite a bit of wear on the inner tabs where it fits into the gear.

Whatever happens, it would be good to take a look inside and see what can be fixed. With a centre pop first, and then very slowly with the drill I had enough room for a small punch to tap on the back of the seal.

The Suzuki GSX750ESD Continues — At Last.

As projects go... this one is dragging. 
I've been doing too much other, altogether mundane, stuff rather than concentrating on the cafe. But I have a couple of weeks off now where I should be able to make an impact. I also had some business cards made recently, purely to advertise the blog, but I want to get busier on the bike before I start passing them round. The backs of them are useful as a service log too, so keep them in your wallet and you'll know when the old beaut needs another oil change.

GSX750 Cafe Racer Progress - Battery Box.

Back in the garage.
Finally got some time to crack on with the wiring and battery box. It's been bugging me for a while because I wanted the loom to look perfect, but sometimes you just need to make a start and fix any issues later. 

I'm still unsure on what sort of speedo/tacho combination I'm going to use too. I'd like two separate units to mimic the typical sixties/seventies bikes, but I have a certain budget too. The modern digital versions get very expensive when you go for quality versions. And although there's plenty of Chinese versions on eBay, do they actually work for more than ten minutes? Decisions...

Gasket Paper.

Doing It The Old Fashioned Way.
Because my brand new, fitted two years ago, gasket broke when removing the clutch cover, I needed a new one. No longer available from Suzuki, you can find quite a few New-Old-Stock ones for sale on eBay - for the price of an aftermarket gasket set! Seriously, are they gold impregnated?

Being careful with my funds, I shot down to Repco for a sheet of the old oil resistant stuff. Just under twenty bucks, plus a further 30% discount that weekend for being an RACQ member, and I was the proud owner of a roll of Flexoid gasket paper. 

Made in England!
That's refreshing, should be good then.

Copying the original gasket, and with a little help from Stanley's knife, and Snap-On's hole punch set, I soon had something that resembled the first one. Even the bloody holes lined up!

With all that done, I had to hear it running again. It's been a while, and I want to be able to run a flush through the engine. So loom was laid on the bike and bits connected where they should be. This loom is a mess! I need to have a big clean up and remove the rubbish repairs from previous bodges. 
With battery connected, I checked for spark - all good. I filled the syringe with fuel until the float bowls were all full and gave it a whirl on the starter. The odd firing occurred and then she was away!

What a difference...

An O-ring makes.
I should be writing lyrics, not playing with bikes. Oh well. 
The various seals I ordered all turned up quick smart from Blue City Motorcycles, in South Australia, with free postage too! Cheers guys. I also found their prices to be cheaper than most so happy with that.
I'd left the oil pump in a container of oil all week, pumping it every now and again to make sure there were no nasties inside. It looks perfect. With new O-ring held in place with some grease, it was ready to be refitted. 

Three M6 bolts hold it in place, then a thrust washer is fitted before the drive pin is inserted and then the gear can be pushed onto the shaft. Finally, a circlip holds it in place. 

It Never Rains...

But it does pour a lot!
The Easter break gave me a chance to not only procrastinate some more, but actually get a bit done on the GSX. I decided to fill the front brake lines with a beautiful blue DOT3 fluid, just so I could check for leaks and feel at the lever. The Chinese reservoir was duly fitted, and ten seconds later developed a leak from the sight glass. Tossers! 
It came off pretty bloody quickly as my freshly painted headlight switch sat underneath it. So a plastic reservoir was put on loosely while I bled them. The anti-dive units haven't held fluid for years so I was expecting problems, but the only issue was a slight leak around the banjo bolts. With a bit more tension applied to the bolts, all seems good. The lever is a bit on the soft side, but should improve once the pads have bedded in. 

Oil be fooked!
Next job was to put a new oil filter in, fill with oil and crank it on the starter to see if the oil light would go out. As previously mentioned, the wire to the oil pressure switch was 'missing' - which could spell trouble. The 'oil light' for today being my test-light mounted between the switch and the live terminal on the battery. It lit up nicely, but refused to go out once cranking. Bugger!
Could the oil pump have gone dry after all the months of sitting around with no oil? Had somebody removed the wire because the engine is fuckered? Was there more to this conspiracy? Oh joy.
I wasn't taking any chances, the sump was taken off to check the pick-up gauze.  The sump itself was full of thick, treacle-like oil and in desperate need of a clean out. Degreaser and brake clean soon had it spotless, but it's a worry that all that  was running round the engine. The oil pick-up was holding a tiny amount of carbon, but not enough to stop the oil pump sucking and pumping the brown stuff around. So, with all that cleaned up and blown out, the sump was refitted with a new gasket.

Untidy Wiring? Recovering Could Be The Answer.

You can put the insulation tape away too!
It maybe considered pedantic, considering the rest of the bike at the moment, but I didn't like the white, heat resistant (?) sheathing on the wiring from the signal generator. It was torn in places, fraying and looked scruffy - not really the look I was going for (for the wiring at least).
So, with a little bit of looking around on the dock of the eBay, I found some Techflex. A plastic braided sleeve which expands when you push it together so that you can get it over various looms, hoses or cables etc. When it goes back to its original length, it tightens back up and looks great. Worth a shot of anyone's money I thought.

Here's the old covering looking a bit dilapidated. I'd cleaned it up as best I could, but some things have their limits.

Refitting HT Leads Into Nippon Denso Coils.

Misfire in the Wet? Weak Spark?
Sat under the tank, they tend to get forgotten. But the leads that take the all important spark to the plugs need to be fully-insulated. If moisture gets in where the coil makes contact with the copper-cored plug lead, your 40,000 volts will probably make its way down the side to earth, rather than putting a spark across your plug electrodes. Why? Because it's lazy and wants the easy path. Wouldn't we all?
If you've ever touched a distributor cap, or lead, on an engine with a misfire, you might have felt the same sort of kick. It's easier to find a path to earth through you, than fire a spark across two metal points that are 0.75mm or more apart, especially in a cylinder containing high pressure air/fuel mixture.
The same can be said for the other end where your plug caps are. The rubber sealing boots are falling apart on the GSX's caps, so I'm putting new NGK's on it. For the price of them, it's not worth taking chances.

So what's that got to do with the price of fish?
Well, the original retaining clips for the plug leads had long since made for the hills. When the bike came to me the HT leads were hanging in by the fact that they were completely rigid and couldn't move, and a bit of good luck thrown in. Don't get me wrong, the bike ran fine, but it would have been different in rain.

Later coils did away with the clips altogether, and came factory sealed with a resin of some sort. As much as I would like them to go back together as Mr Denso wanted, without new clips, I'm going to have to seal them in semi-permanently too.

New Bits, Missing Bits And Dodgy Bits!

New parts are rolling in fast.
But some of the old bits seem to have done a bunk! I cleaned, painted (then scratched) a LH handlebar switch last week. Convinced it wasn't the one off this bike, and that it came in a box of Katana bits, I did it anyway. Why didn't I think it was off this GSX? The choke lever is snapped off on the Katana one.
I just went through all the pics I took of the bike and, sure enough, the choke lever is intact on the original switch - but where the f#*k is it?

I had a massive clear-out and general tidy in the garage this weekend and went through all the boxes. The switch and clutch lever have definitely gone AWOL. Oh well, hopefully they'll turn up soon.

In the meantime, new acquisitions have been turning up while I had some spare cash. Needing new master cylinder reservoirs, I went looking on good old eBay. A nice, anodised black, aluminium cylindrical reservoir was found for the princely sum of $7.55 delivered. How could you possibly go wrong? 

Looking for a Project. Buy Buy Buy!

Just missed out on an old XL250 on ebay. Yes I should have put a higher bid in but sometimes, when you're in two minds, you chance it to fate. It's not exactly a classic BSA or Triumph so I'm not too bothered.

So that leaves me scouring the web pages for restoration projects that are close enough to drive to. Never used to be a problem in the UK, but in Australia, it could be a days travel to get to the next state, let alone the other side of the country!


The post above was the start of BikeTech7.
Not very interesting was it? No pictures, hardly any text. Back then I thought you just wrote something in your blog and everyone was desperate to read the rubbish you churn out. Not actually the way it works, but then you knew that... didn't you?
I started the blog to keep an online account of my projects, and help others who were going through issues of their own and maybe had no prior knowledge. It's all a bit of fun, and hopefully helps you keep your bike on the road, or gets you closer to finishing it. 
Got questions? Just ask, I love to hear from you.

Meanwhile, here's some pics of one of my previous bike projects. It's a 1964 Norton Jubilee. The smallest capacity bike Norton ever built, it's a 250cc parallel twin and, although not completely original, looked pretty good when finished.

Thanks for checking out Biketech7 and I hope you can stick around.
