It's been up for 3 hours and no one has posted this yet? Slackers. Dave even gives a shout out to the forum! I'd love to find some of that Olins suspension and put it on the Greenie. In my spare time of course. I can't even find time to adjust the valves.5 points

I assumed there would be a post about it. Now I get to have @wavey_davey1 be mad at me for posting the LDG video before he did.4 points

While Fortnine did a great job of explaining the fundamentals, the specifics and nuances are very complex. Headpipe diameter and length are the primary indicator of RPM range, but inlet and outlet cone length, end diameters, length between- all affect peak power, power spread, whether there's a smooth transition into and out of the powerband or a razor-thin line between 'on the pipe' and 'off'. When I raced flat track, every 2-stroke racer who had the skill to tell the difference and the means to acquire them had 3-4 different pipes to choose from depending on track length and condition. It's almost like it's rocket science or something.4 points

What kind of adapter goes for the prick inflator ? i would like to see the pressure readings before doing ANYTHING down there3 points

Two of my favorite two stroke experiences were racing a TZ250, which was a lot like the above mentioned TZ350, and a KTM 440 EXC dirtbike. The TZ250 was the classic two stroke, no power, followed by some power as you rev. Then, around 8,000 rpm it started to make noticeable power. At 10,000 rpm it kicked in and went, pulling hard up to around 13,000 rpm where it was done as quickly as it started. That bike was serious fun on a track. My other favorite two stroke was the exact opposite. The KTM 440 was a monster that didn't have to rev to make power. It was almost friendly at idle, but at some point just above idle it turned into a beast. It quickly went from making some power to making massive power. It was a dirtbike, so it didn't have a tach. But it didn't need one. The power was always there. It was a case of too much power being too much fun. I was not really faster on it then I was on my DR350, but my smile when riding it was way bigger. It would plaster a smile on my face the way it yanked me out of corners. It was like the way spaceships hit warp speed or light speed in sci-fi movies. Expansion chambers can make two strokes deliver amazing power. They don't automatically make for a peaky motor, they don't always means power up top. They can make power wherever they are designed to. Thinking of them as acoustic resonance is a good way to look at them. Depending on how they are designed they can make power down low, in the middle, or up top.3 points

Y’know it wasn’t that long ago when most fuel stations in the uk had a tyre pumper compressor inflator pumper. They were free initially, then were 20p, then 50p, then a quid. Then they were always busted, and now they’re all dodo likes. ☹️ I recently saw an esso, or shell or whatever evil corp, advertising that correct air pressures in ones tyres will increase efficiency, help the environment (!) and swell your prick magnificently. 😬3 points

This is exactly why they video is educating; because those expansion chambers should be designed to fit a very specific type of engine, targeting a narrow rpm band. I purchased mine from the manufacturer of my engine, and it was supposedly tuned to that engine type. However, nothing was specified on what rpm range it was designed to work best. All the guys from my moto club installed those chambers on their bikes, and it now occurs to me, the only certainty was the unbearable noise produced. As to the increased power, no idea....3 points

I got my parts from Midwest Control Products in Bushnell , Il. . www.midwestcontroproductsl.com TR6-150 threaded rod. DNTFL-6 rod end , DMCS-6 ball joint , DNTFL-6 ball joint , DMCSL-6 ball joint. I will never understand why they installed two r.h. thread rod ends on an adjustable rod. I di turn this quite a long time before I realized I was going nowhere ! Hmmm IDK why I went crazy on the rod ends but I got all of them and picked the ones I liked. On the threaded rod , just get two and cut the first one the same length as the original , reassemble and adjust to suit you. You have the extra rod to work with ! This stuff is inexpensive and top quality. You will not regret doing this. This was from Aug/2011 so I hope these part #s are good. These people manufacture high performance things so this is not a hokey-pokey place. Good luck3 points

That's this bike. The photo of the front tire, first photo in the thread, turns up in the video about 20 minutes in. @wavey_davey1 great to see the bike on the road, and on the correct side of the road into the bargain.2 points

Ha ha My CR 125 motocrosser was the same... Nothing and I mean nothing below 7500 then all 20 horsepower at once thru to 10,500 ... Doesn't sound like much but it only weighed 80 kilos and I would've been 10 stone wringing wet back then too. Loved it! Geez I would've loved to have had a go on a TZ back in the day as no way in Hades I'd fit on one now!2 points

I was allowed to ride a TZ 350 one time. Proper race bike, with slicks and all. No idle, started working at 6,000 rpm, went mad at 8,000, tailed off above 10,000, and just managed to get to 12,000 without any additional gain. Loads of fun, but that was on a track. On the road, it would have been a pain, if not to say completely useless.2 points

Well , you need to purchase a l.h.thread ball end and a threaded rod w/l.h. &r.h. thread and go to work. I will try to find some part #s. This is the best way to fix this so you can trim this height to suit you .2 points

There are a couple options by changing the shift mechanism. You can lengthen the connecting rod or rotate the pawl arm on the gearbox one tooth clockwise (which will likely necessitate changing the rod length to keep the arms parallel). This may require some 'fettling" to make both you and the gearbox happy . . .2 points

He did not learn to say Guzzi properly, but I will forgive him. This Guzzi 2013 is a mirror copy of the one I am after, pending the sale of my Quota... This guy has published a lot of videos about the problems he experienced, which are very educating to me; I did not know the 2013 Stelvio had a clutch recall. I did not know about the throats wearing off either.1 point

Windows down. Had a looong roadtrip in the US in 82 with a 66 Catalina. Bought from the Norwegian seamans church in Brooklyn, 250$. Windows open in Death valley, no AC. Keep arm inside, or severe burned. No ac was intentionally, feel nature. Today, of course not . Cheers Tom.1 point

Like said it's been a reccent topic of conversation between the wife and myself and we have actually done a survey when driving recently. It came up because on the Supra forum people whinge incessantly about the wind buffet when driving the Supra around with the drivers window down. You can buy a simple stick on device to eliminate it but I don't need one because I never drive with the windows down so I kind of got interested in how many people do and it went from there. The sunroof and rag top thing I've had for 30 years or more though.1 point

Dunno if that's an Aus thing, rarely see anyone do that here- other than the poseurs cruising their pinky rings.1 point

Well then, since it's free at least for basic I may have to give it a shot. Probably not reasonable to ask for something specifically tailored to my whims.1 point

Did that on the Quota... the shift lever height was better, but it kept coming out from the gear lever.... Now that I have installed a rubber insert in the foot peg, it is a better fit...1 point
-
Well not really because they even drive around with the window down on days that don't require A/C and in very late model cars. If they were all driving old beaters I may take your point. Phil1 point

I'm a bit loath to say it mate, but that is more or less exactly what Resolve is. I'm not even sure there are all that many other products out there. To be honest, I don't do very much editing at all. Even so, my experience is, "simple" products are generally crap. To get good results, you need a good product. The trick is to concentrate on the features you want to use, learn them, and ignore the rest.1 point

Book it up to environmental protection. The air that comes out of the crankcase is heavy with oil vapour. It's better for the environment if the re-condensed oil goes back into the motor.1 point

Could have stuck to history without the political commentary, but fundamentally good. Oh, and "The engines are identical" is at best misleading, and at worst, well, misrepresentation. Anybody who's ridden one knows it's not 170 horsepower, doesn't come on like a light switch- in fact, the powerband is much less abrupt than a Kawasaki Triple. Even if every part number in the engine is the same, the pipes and the porting make all the meaningful difference. On most 2-strokes, an hour by a professional and a tailored pipe can add 10-50% to any 2-stroke, depending on era and state of tune.1 point

Sound and Video has always been, and still is, seperately recorded in film production. I'm pretty sure everyone here would have seen at least a photo of one of these at some point Filmtechniker 15:05, 24. Aug. 2008 (CEST) (Transferred by Heubergen/Originally uploaded by Filmtechniker), Copyrighted free use, via Wikimedia Commons It's purpose is exactly what "some people" achieve by honking the horn. Hold it in front of the camera (film cameras don't record sound) and bang the top bit together to make a short, sharp, distinct sound. Obviously a clapper board is not absolutely necessary, assuming you don't need the blackboard on the front to note take number, date, whatever. You can use two bits of wood, clap, bang two hedgehogs together, anything that makes a short and distinct sound and clearly shows the "moment of impact" on camera. Then, "all you have to do" is line up the sound with the picture in post-production. PS: I would use some variation of the clapper board even when using a camera that records sound. Experience shows that it is much, much easier to find a spot in an audio track if you have pictures to give you visual cues where you are up to in the recording. For instance: start the audio recorder, count seconds up to starting the camera, get sorted and clap in front of the camera. Find the pictures of the clap, look at the elapsed time, and you know where to look for the sound of the clap in the separate audio recording.1 point

I know a number of YouTubers use two separate devices for moto video; obviously the cameras, but they put a sound recorder under the tail section, or wherever the sound is best. Then they honk the horn so they have a point to synchronize, and add the exhaust sound over the video, sometimes with a voiceover if the camera sound is ugly.1 point

The best guitarist I have ever heard, most likely. At least at short range. This bloke was at Uni the same time I was, and I recorded a few demos for him, with him and a bloke playing Vibraphone. at the time, he was paying the rent playing in this band. Another Austrlian. Unfortunately, I've never heard him live. Would love to, though. The video is quite old, I think, but he is still around.1 point

One of the best flat and finger pickers I've ever heard. Grew up playing bluegrass, but can play and sing anything. Here, he's covering Dylan, the only person I've heard that gives the same feel.. Don't know how to imbed. Well I see it did it automatically.1 point
