We love a “hack” here at Garage Night, as demonstrated by our project to put KTM forks on Richard’s BMW F650.
So when Trent found out about a way of using baking soda gun to clean up bike parts we were dead keen to give it a go. All you need is an air compressor with a duster gun, some plastic line, insulation or gaffer tape and a supply of bicarbonate of soda. And you can see the results in this episode of Garage Night TV.
Soda blasting is a great alternative to sand or shot blasting, because the blasting medium doesn’t damage the underlying metal. It uses the explosive force of the tiny soda particles as they shatter on impact to knock the dirt, grease, paint etc off the surface.

It’s warming up in these parts and I’m getting closer to putting the swingarm back on my bike. Since Trent made me a linkage bushing in the last episode, I’ve been gathering new bearings and seals, getting the swingarm powdercoated and even fabricating my own chain slider out of a special hard-wearing plastic.
Some bikes use simple bronze bushings in their various rear suspension linkages and pivots, but many use needle roller bearings. That’s certainly the case with my bike, which mixes caged needle rollers with “full complement” bearings.
Watch the video for all the details, but essentially the full complement bearing is the more compact of the two, capable of carrying higher loads for its size but prone to its fiddly little rollers falling out when handled because there’s no cage around them.

The winter months are a great time to catch up on bike maintenance, so I have finally removed the rear suspension from my Cagiva Elefant 750. I bought the bike secondhand a few years ago and was prepared for the worst when I finally got round to this task.
And the worst I did find. Bone-dry bearings in the linkage had deeply scored the hardened steel bush/spacer/shaft that runs through them. And being from Cagiva, this part is nowadays ‘unobtainium’ - you can’t buy it anywhere. Spin one up on a lathe, then? Well, once the part is made the steel needs to be hardened - not something that’s really feasible in a home workshop, at least not if you want the part to last.

We did it! Mountain Madness 2009 is done and dusted, with Garage Night “satellite squad” the Mushman Candidates placing FIRST in the under-650cc class and 2nd outright on points.
Trent and Pete again teamed up with KTM rider and navigator extraordinaire James to produce an outstanding result - though scoring second overall for the second year running left them even more determined for outright victory next year.
Our not-so-hotly-competitive “official” entry Team Garage Night - myself (Waz), Richard and Etienne - placed 8th out of 14 in the over-650cc class.
Richard and I hadn’t ridden on dirt for years, and for the three of us it was our first outing as a team. Not making excuses - but it took us a while to find our offroad legs. Continue reading ‘Ep 13: Mountain Madness 2009′

This is it. After two years of theorising, trial and error, parts fabrication and emptied beercans, we’re ready to bolt the new forks on to Richard’s Beemer.
Last episode we discussed exactly what components we were using and the modifications being made to fit them up. This time round we’re actually installing the yokes, steering lock and stops, forks, wheel and brakes – everything that’s needed to get Richard’s “number one” bike back on its wheels.
Pete and Rich show off some custom bits that we made - a neat adapter plate set-up for the steering lock and a tidy steering stop that bolts up nicely.
As we post this episode, Horizons Unlimited Mountain Madness (the HUMM) is less than a week away, so Richard’s suspension will be getting a full workout as “Team Garage Night” (Waz, Richard and Garage Night apprentice Etienne) go up against about 150 other competitors, including last year’s second placegetters the Mushman Candidates - Pete, Trent and James.

We’re back with our much-anticipated special project: fitting a set of KTM inverted or USD forks to Richard’s BMW F650 Dakar.
Now that we’ve got Richard’s “number two bike” back on the road, it’s time to get cracking on “number one” - the F650 Dakar that he rode to Singapore in 2003.
While no.2 (also an F650 Dakar) is Richard’s daily hack, no.1 is the sentimental favourite because of its history. A while back Richard decided to turn it into something special and has been progressively getting things overhauled, powdercoated, polished and blinged up with stainless steel bolts.
But the big-ticket item is a set of KTM inverted or upside-down (USD) forks - the factory-fitted variety made by WP Suspension. Whenever we’ve mentioned this on ADVRider or other forums there’s been a big response - so this episode, where we explain the conversion, should prove popular.

Garage Night TV has turned 10! Well, it’s our 10th episode, anyway. In this instalment, Pete replaces the rear wheel bearings on his Honda Africa Twin 750 - and gets a nasty shock when he finds what some previous mechanic has done in this department.
Sealed bearings. Great! They come from the factory with lots of lovely grease inside, and their own integral seals to make sure the grease stays in, and the muck stays out.
Right? WRONG! For me, the biggest revelation of this episode came when Trent popped open one of Pete’s new bearings and showed that inside was little more than a token smear of factory lubricant. So if you really care about those bearings lasting, it’s a good idea to check them - how to go about this is one of the numerous tips you’ll get by watching the video.
If there’s a lack of grease, you might consider adding some yourself. It’s not recommended to pack them solid, though, due to the possibility of overheating or hydraulic lock. There’s a bit of debate on this, but about 1/3 full of grease is one recommended figure. Continue reading ‘Ep 10: Replacing rear wheel bearings’
Watch Waz and Trent dismantle the wheel in Ep 3: Sand, heat and nipples and Episode 4: Wires, shocks and smoke.
A spoke wheel is a thing of beauty. Here at Garage Night, you can’t tell us otherwise. Cast wheels might be acceptable if you ride a road toad, but if you’ve got spokes, you’ve got class.
Just think, each thin metal spine is fragile on its own, but strong enough when laced together with a bunch of buddies to bear several times the weight of your bike when you’re full on the brakes, or keep your wheel from crumpling when you smash through a wash-out. And no matter how you try, for elegance of both form and function a cast or billet wheel can’t come close.
An old, neglected spoke wheel is NOT a thing of beauty, though - as I found when I bought a complete secondhand USD fork front end for my bike and discovered the seller had been less than honest about its condition. The Garage Night guys were never going to let me put it together in that state. So the wheel had to come apart. Continue reading ‘Ep 9: New spokes on an old wheel’
Missed part 1 of Chain and Sprockets? Click here
With the old chain taken off and consigned to the trash, Trent and Pete remove and examine the old sprockets, install the new ones and rivet the fresh chain in place on Pete’s KTM 950 Adventure.
Along the way, Trent discusses correct chain tension, the different ways a front sprocket may be attached to the countershaft, and why you should NEVER use a worn sprocket with a new chain - at least not if you want the chain to last.
Pete talks about how changing the sprocket ratio - in his case, the number of teeth on the front sprocket - has improved his bike’s driveability. There’s an interesting aside, too, on the possible negative consequences of going for a smaller front sprocket. Continue reading ‘Ep 8: Chain and sprockets part 2′
Trent and Pete are back from Mountain Madness 2008, and Pete’s KTM 950 Adventure is in need of a new chain and sprockets. It has actually spat out a couple of rollers - not something I have seen before, but an obvious sign of serious wear and tear.
You can really blow some money in this department by not keeping tabs on things. A chain that is lubricated and correctly adjusted will run smoothly with minimum wear. A dry chain that is too loose or too tight will not only wear prematurely itself, but move around on the sprockets and chew out the teeth.
The sprockets will respond by putting further stress on the chain, since the teeth and the links no longer mesh properly, and you are into a vicious cycle that ends with you shelling out cash much sooner than you should have - or, worse, stranded by the side of the track. Carrying a spare set, are we?
