XS650: Professional Motorcycle Tuning, Australia   Leave a comment

DARYL, PMT, MELBOURNE

My first contact with Daryl was back when I joined the Australian XS650 Club. After finding Terry’s website. I had picked up an XS650 Special for a song. Had been sitting 10 years. Reigniting an association I had had with these beauties during the 70’s and 80’s. Funny how the worm turns. Connects.

Was talking to a mate about my find. A warm far-away smile spreads across his face. Takes me out to one of his sheds. An 82 standard sitting in the corner. Sharing space with other beauties he hadn’t been able to part with. Naya, to cut a long story short – I started telling him about Daryl’s 270° rephase pins. We spent the next few weeks ‘touring’ around Europe (touring? – hmmm, hard physical work, long days, hotel beds – a dream). Boys back in town. Peter hands me a small package. Surprisingly heavy. You got it! 270 heaven. No looking back now. I’m converted. Wanted to do some remedial revision last year, to the 270 motor: clutch, gearbox, cam chain and a little headwork – ended up adding a 750 kit too. Checked the crank – no problems. Still, I added carrillo rods, balanced and welded it all together. Mum shat buckets of blood.

This isn’t my story, so back to the point.

Daryl isn’t just Mr 270. He is Professional Motorcycle Tuning. Melbourne (a truly beautiful town, Port Phillip, Yarra River, AFL and the nearby Phillip Island circuit to name just a few teasers – well worth a visit).

Where to start ? At the beginning.

First ride on a motorcycle:  within a week of my 10th birthday, May 1970. I said there and then that I want to be around them for the rest of my life!!!! I am now 50+ young

I have, luckily enough, been able to do this most of the time. I moved to Melbourne, 1978. Worked as an apprentice electrician. I didn’t really like it. Spent most of my time at a mates motorcycle shop, helping. How I got my first XS650.

An XS2. In a million bits. All in boxes. Engine totally dismantled.Forks removed, swing arm in another box. But, everything was there. Over the next few months we rebuilt the engine, installed the forks and swing arm, some new tyres, got some replica Dunstall mufflers and another mate painted thetin. Cool looking wheels.

 I rode that bike around Melbourne. Did a trip up to Sydney and back. Never missed a beat. I came out from my electrical job one afternoon and it was gone. I thought the guys I worked with might have moved it on me as a joke, but no, it was stolen. Called the police. They didn’t really care. Never found it. Only had one photo of it – long lost. I really liked that bike.

 After finishing my apprenticeship, 4 years, I joined the army for 3 years.  Since then, I have been involved in the motorcycle industry, working as a mechanic until becoming the service manager at Raceway Suzuki, owned and run by the guy that helped me build that very first XS650. Small world.

Took an offer, 2000, to join the official Australian Suzuki superbike team as a mechanic, boring job, pull one engine out, put another one in. That was thelast year that we ran full spec FIM superbikes down here. All came straight from the factory. Got to look at the inside of one. It was not a 750cc engine.750cc was the limit. I know how big a 750 piston is. This was way bigger. Factory tricks. A mate working on the Yamaha team told me they had “fat” engines as well. How can privateer do battle with that??!!

 Season finished. We won the championship. No job. Tried working at a Ducati dealership. Didn’t “fit” into the Ducati thing and left after 3 months.

 What to do now? Start my own shop. Professional Motorcycle Tuning. I opened 1st Feb 2001. Best thing I ever did !

PMT workshop, Melbourne … a city definitely worth visiting

 

I have owned XS650s for most of the time, all roadster types (447), I don’t really like the special version. Too american for me. But hey, they pay the bills.

I started doing a few engine rebuilds for a few people put ting a few of my little tricks into them. Word spread of what I can do. Terry (Toota) used to get the rephased pins done but his engineer retired, so now I do them. I am the only place in the world where they are available.

 I always have 2-3 XS650 engine rebuilds on the go. They vary from stock rebuild to big bore rephase and everything in between. XS1 is my favorite engine to do. Stronger cases, taller 1st gear and the head, all valve inspection covers the same. 3 bolt. Some people think it is a head off something else. I am working one at the moment that is being de-stroked 6mm, down to 62mm, 256 conrods bushed to 20mm and an 81mm bore. 640cc.Rephased, what else? Got some titanium valves on the way from USA. Still waiting. Special cam, my dry clutch and high ratio primary gears. XS1 gearbox.

If my math is right it should be able to spin to 10,500-11,000 RPM, piston speed 22m/sec. Bee-hive valve springs. Not that all hard to do, the secret is in the set-up.And the best bit, most of the parts are available across the counter. The guy that does my head porting is a whizz!

Now, my awesome tracker is on the back burner for a while. Too much customer work on the go at the moment and I have my TX750s to play with.

One thing I have been working on is an XS650 dry clutch. Just about got it done. After I do some testing (race track) on it I might start to do kits, costing ?? $3000-$4000.No one else does them. Someone in Japan does a kit for the SR500 every now and then. They areall sold out not long after being put on sale and they are a similar price.

 What else?? Yes, my belt drive. I am doing one for a customer at the moment. He now wants to fit a Motolana swingarm, 25+mm shorter than stock. I can’t cut and join a belt. Yet! Another spanner in the works. And he wants his stock one braced. A removable partwill have to be put in the bracing. I can do it. I can do anything. The belt drive? About $1000. Belts on Harleys last tens of thousands of kms so I can’t see a problem. I used to look after an XV1600A that in 100,000 km had only one adjustment.

I have been working on a light-weight charging system.It will also incorporate an ignition for all styles of engine, std, 277° or 270° crank, as required. As the cam chain stretches the ignition timing changes.With my system it is truly set and forget. But more on that later, no price yet but it will be reasonable for what you get

Some of Daryl’s builds:

750cc, 270 deg crank, Probe ignition, 34mm Mikuni carbs, TRX850 front end, Motolana SR500 swing arm, SR500 fuel tank, SR500 Nitroheads seat, and a lot of over the counter parts.

barrels,
