  1. Great, thanks. I think we'll have to disagree on the definitions. I'll stick with my definition of: Double Blip - blip throttle to lift front wheel, when it hits obstacle second blip to drive the rear wheel in to the obstacle. Zap - Lift front wheel (either blip or a bit of clutch), when it hits obstacle clutch dump (combined with building revs prior) to snap the bike up and get extra rear wheel lift. Splat(ter) - Aggressive acceleration, usually with clutch dump but not necessarily, to launch the rear wheel directly into the obstacle. May involve a kicker or not. These fit a multitude of situations and have clear points of difference. Look at lineway's son in the photo he just posted - no kicker but assuming the front tyre never hit, that's a splatter by anyone's assessment surely? Plenty of the indoor trials obstacles require huge splat(ter)s off a smooth stadium floor, so there's certainly no requirement for a kicker of any sort. Some of the really big splatters happen at pretty high speed, so I doubt there's much if any clutch involved - that's not something I have any intention of finding out for myself! My personal analysis of the zap vs blip is that the zap gets so much more lift for two main reasons: The extremely fast acceleration of the bike from the clutch dump with the front wheel compressed against the obstacle causes it to very rapidly rotate which results in the forward mass (front wheel, forks, engine) accelerating almost vertically - this gives some good vertical momentum to help carry the bike that direction. With the throttle snapped closed, as soon as the rear wheel has accelerated to the speed of the flywheel the tension drops off the chain, allowing the rear suspension to extend and help spring the bike up (the front suspension is doing the same as the bike rotates up away from the obstacle). The blip uses the same compression of the front forks and resulting rotation of the bike, but without the fast acceleration it has much less result, and using engine acceleration to drive forward means the chain isn't going to drop tension so the rear suspension can't extend as freely. This also helps explain why you have to contact the obstacle below the top (something I know I'm not good at) - so the front of the bike gets forced up when it's driven forwards. Maybe if you drove into the obstacle quite fast you'd get a bigger lift as the bike rapidly rotated up - another thing I'm not sure I'll be doing any personal research on! A good discussion anyway.
  2. Nice! Maybe when I get to his age I'll be doing that too. No, wait, that was decades ago. Oh well.🙃
  3. Yes, it's so depressing, makes me want to take a drug overdose. Sorry lineaway, only joking, well partly anyway. Only about the drugs, not the depression.
  4. Thanks for picking up that error in my writing - corrected. Perhaps I should have included roll-up's kissing the front in this video. I just wish I had the skills of Jimmy, Pat and the others who make such good teaching videos so I could actually demonstrate effectively. If they would only put cameras on their bars like this then I certainly wouldn't bother doing it myself! So often I watch the videos and just can't see accurately what's going on with throttle and clutch timing, and if you don't know what you're trying to do with throttle and clutch then what hope have you got? So much of it is about accurate timing of the weighting, unweighting, clutch & throttle, "almost right" is about as effective as "completely wrong" in my experience! I'm afraid that leaves me somewhat confused (more so than usual anyway). Jimmy's videos are excellent, certainly among the best series I've seen (and I've wasted way too much time on YouTube watching trials!). The trouble comes with some of the translations, as in this video. The first demo. says "Zap / Touch Front", the second says "Double Blip / Zap". They are clearly different, otherwise he wouldn't make two demo's, so why are they both labelled Zap? If we're going to have two different techniques with the same name we might as well just call everything "riding". I would call the first a Double Blip / Touch Front and the second a Zap as there is clearly use of the clutch to launch the bike after the front wheel hits. When we come to Splats I don't understand what you mean by, "Your splats are a zap without touching the obstacle."? My understanding is that if the front wheel doesn't touch, then it's not a Zap. In my demo there is a rock being used as a kicker, and the back wheel lands on the obstacle - so why is it not a Splat, albeit not a startlingly good one? I'd add that a kicker is not requirement for a splat as Jimmy shows in technique 4. You could Splat with or without the clutch, the key as I understand it is launching the rear tyre airborne directly into the obstacle without touching the front tyre. If there's a word or term, there's a definition. So what's your definition of Double Blip, Zap and Splat(ter)? That might help clear things up. I've asked Jimmy Ertzer if he'd mind setting up bar-cams and making videos - that would be an excellent outcome!
  5. You're probably partly right to blame him for that. Mostly I suspect it's due to Covid dramatically reducing the global use of oil. Trump's contribution seems to have been his determination to ensure the USA is one of the hardest hit countries on the planet, thereby reducing U.S. consumption even further. But how good would it be if he'd spent a even a moment actually trying to reduce dependence on fossil fuels in the first place? I used to be embarrassed when we had Tony Abbott as our prime minister, Trump almost makes me proud of Tony. Sad.
  6. That's priceless! Sadly we have one State in Australia that does not have a single non-Murdoch "Entertainmentpaper" - not even a single local rag. What hope have we got.
  7. Lineaway I suspect you underestimate the potential effect of another 4 years of Trump. Maybe in the short term not a great deal of difference, but perhaps in America you don't see just what most of the rest of the world thinks of Trump, and how they will be pretty much forced to act to contain him if he gets another term. I really can't see that you'd come out unscathed if America becomes increasingly isolated by much of the developed world. I don't know how it looks and feels within America, but from the outside it feels like watching a replay of the fall of the Roman Empire as Trump makes the most bizarre, destructive decisions, the complete inability to make an effective response to COVID or apparently understand basic science around climate change - it makes the country a laughing stock to the rest of the world. I'd suggest there's good reason for much of the more independent media caning Trump. On the media, I must both apologise and thank you Americans for taking Rupert Murdoch away from Australia! What his networks publish can not be considered "news"!
  8. For a bit of fun I made a video of Double Blip, Zap & Splat on the same obstacle with the 2 bar-cams (throttle cam is a bit better since I rubber mounted it). I've posted the link to the video in new thread. If nothing else it should clarify my (mis?) understanding of the three. Definitely not something to watch to learn technique, but maybe it's useful as an explanation at least of what I understand (right or wrong).
  9. After a bit of what I saw as misunderstanding around the differences between Double Blips & Zaps from my first couple of videos with bar-cams I thought I'd have a go at making a video with those two plus a Splat. I'm not pretending these are particularly good specimens of the technique (large understatement!) but maybe they give a fair idea of what I consider the differences. Double Blip doesn't use any clutch - just throttle, Zap uses rev and dump the clutch as both suspensions bottom & Splat uses rev & dump to launch the back wheel directly into the obstacle. Willing to be corrected, but this is my understanding. EDIT - corrected "Zap" to "Splat" thanks lineaway.
  10. Thanks for the feedback - always trying different things to find out what works. Timing is certainly the key to these things, watching that video I actually wondered if the second blip was a bit early - you can see the throttle winding on well before the wheel actually hits. You could be right on the "too far forward". I think of it that the rider needs to accelerate their body forward to where the bike is about to be just a moment before the bike accelerates there, otherwise you get left behind as the bike can accelerate much faster than the rider can, or you have to hold onto the the bike to let it drag you forward which stops it from reacting quickly. Not sure I've explained that well ... Anyway, there's probably a fine line between getting forward too far / too early and getting left behind. I'm not sure I quite agree on the "landing on top" on this one, here's a still frame from that video as the wheel impacts. If it was much lower it would still be on the ground! , I also think there's a misunderstanding around "Double-Blip" vs "Zap". Rightly or wrongly this is the way I refer to them: Double-Blip - there is no clutch use at all. The Blip refers to using the throttle only. The clutch is out when you start riding toward the obstacle and stays there the entire time. Zap - the clutch is used in conjunction with throttle. So this video is about the Double Blip - no clutch use at all, the tiny bit of lever movement in my video is just the free play. This also applies to CptStarck's post above, Jan Peters is showing a Zap, not a Double Blip. Pat Smage & Ryan Young Double Blip video.
  11. Part 3 in my micro series. Clutch and throttle cameras synced to maybe give a better idea about timing. Obviously not much going on with the clutch in a Double Blip. This clip I've tried to show the difference in reaction when the back wheel hits with throttle on and off - it's perhaps a bit subtle, but it should give the idea I think. Throttle on and the bike jumps much more, not as smooth rolling over. Don't take what I offer as reliable knowledge - I'm just a dabbler of little real skill!
  12. Staying on the same Zap theme - I knocked up a short stationary zap video, this time with clutch and throttle cams. Unfortunately the throttle cam picks up a lot of engine vibration - I'll work on that. As before - keep in mind this could be the vision impaired leading the blind. I'm more than happy to receive constructive suggestions. I've filmed a basic double blip over the same log, trying to show the effect of throttle on and throttle off as the back wheel hits. I'll put that in a different thread on Blips when it's finished.
  13. My riding and video skills are certainly nothing to write home about, but I'm happy to have a crack at making some more of these mini-clips - it's kind of fun doing it anyway. I find that the typical instructional video makers like Pat Smage and co. often leave out some of the vital timing and coordination detail that makes it all come together for me. Possibly they learnt this stuff so long ago that they don't even think about some aspects that we plonkers are still barely aware of. Can be frustrating. I remember when I first twigged on the right (more or less) clutch timing - it was revolutionary! Anything you're particularly interested in seeing? If I can, I'll see what I can put together. I was thinking a stationary zap or "stuff" maybe? Perhaps hopping for traction?, although I'm not sure how helpful my technique might be on that one. I'd like to do rear wheel hops, but sadly they're still not part of my repertoire really. Ideally I'd hook up with an expert rider and put cameras on their bike then take it home and edit it up. No experts near me though.
  14. Great to hear it's of help! I only wish I had some other skills worthy of videoing. I played around with setting the clutch cam to also show the throttle better but couldn't make it really work. Getting off the throttle is definitely something I found important. I think the difficulty for most of us learning is that it's a bit challenging to wind up the revs before dropping the clutch, so we do a half hearted blend of throttle and clutch at almost the same time. My experience is that it just doesn't work. With throttle on the back wheel just sticks to the ground. Jimmy Ertzer's videos are really worth a watch, he's got some good progressive skill building exercises.
  15. Thanks, that's somewhat reassuring. I'll give it a few more (frequent) oil changes and hope for the best. I hate it when something breaks for no apparent reason!
