    Tire musings

    Oh I did that on my trail bike, well Tubliss... And yeah, it's mind boggling how much grip it has, especially combined with the gummy hybrid tire. Just need to learn to trust that the bead doesn't need a rim lock like the trail/mx bikes do.

    Tire musings

    Quite honestly I'm not sure what it has. I'm sure that at least at some point it was tubeless, but it's 20 years old, and I'm probably the 3rd or 4th owner. Could be anything inside there, maybe even rocks, lol. Again, this exposes my noob-ness, but I guess it's just a foreign concept to think about a rear motorcycle tire without a rim-lock running 4 psi... Is there just some magic trials voodoo that keeps the bead on at 4psi? My tires definitely need to be replaced sooner rather than later, they are cracked and worn down, but at this point still holding air, so I'm letting that bear sleep until I pull the trigger on new tires. I'd rather not take it off just to see what it has inside until I have a replacement on hand. My luck it wouldn't seat again or the tire would fall apart as I'm putting it back on. I found that since I used HD tubes in my trail bike, the weight penalty of Tubliss was effectively zero, and the advantages of being able to essentially run zero psi with almost no chance of blowing a bead was of great benefit.

    Tire musings

    Okay, I couldn't really find a discussion thread on tires aside from the odd mention of tire brands or tubliss here and there, and since I have a Beta, I'm putting it here. If there's a better area for this type of post, I'll certainly head over there... I'm mostly curious as to people's thoughts on the different types of tire (tyre) systems. Not brands like Dunlops vs. IRC or whatever. I'm thinking about true tubeless vs. tubliss vs. tubes (light or heavyweight) I'm new to trials (but not new to trail bikes), so I'm really curious what people are running. I recently put Tubliss on my trail bike and absolutely I love it, and I'm tending towards that when it's time for new tires. I've really been happy with the low pressure performance and the "rim lock" of the tubliss system, but it also comes at a slight weight disadvantage (unless you're running heavy duty tubes), which I'm sure I'd notice more on a trials bike. Anyhoo, thanks in advance, and happy riding

    Interesting. I've heard more that you just want the front and rear to match, so that it feels balanced. Sounds like this is your first trials bike (mine too). Do you come from a trail/mx background? While this is my first trials bike too, I do come from a fairly extensive mountain bike background (and 15 years of moto trail riding, too). I used to teach maintenance classes and riding clinics thru the shop I was managing. The main thing is to not really get too wrapped up in the numbers. Suspension is so personal. Just like where you like your brake/clutch lever to sit, it's all personal preference. Just go find a bit of trail or a section where you can repeat it over and over. Ideally it will have a fairly varied terrain (rocks, ruts, jumps, whatever). For a trials bike, this mainly depends on your skill level, it may be as simple as just some slow circles, and a rocky semi-technical trail somewhere... Make sure it's something you can do fairly easily, because you want to be able to concentrate on your settings, not getting thru the section. Then start messing around with your settings ONE at a time, and repeat that section of trail. When you only change one setting at a time, you know for sure what changed and how that affects the ride. Keep changing that one thing until you feel either it getting better, or getting worse (then go back to where it felt best). This is my plan once my shoulder heals. Just get out to the local OHV park and mess around with the suspension for a couple hours. From the videos/tutorials I've seen, especially coming from a trail bike back ground, the setting will be softer than you think. Like that video I posted, you're probably going to bottom out on anything over 3 feet. Anyhoo, best of luck

    Not sure if you saw my reply to your post in my other thread, but I'm running ~65mm sag in the front on my bike 2000 Rev 3 with the USD forks, and that seems perfectly rideable, but granted I haven't really ridden it since I first bought it (except tooling around in the back yard). I weigh 175ish (~80kg) without my gear on, so I'm not that different from you. So I don't think you should be trying for ~20-25mm sag with your weight on it. That seems pretty hard for a trials bike.
  6. So the picture I posted was correct? Crap, okay, I could swear I had seen fork rebuilds with the washer between the 2 seals, so the retainer clip sits against the washer, not the rubber seal. I see my mistake now, thanks for the correction! Good thing I haven't actually ridden it... Hopefully I can get them out and redo it without ruining them. Damnit.
  7. 22mm of sag seems awfully hard. That sounds more like sag for an MX bike. I'm currently running about 65mm in the front (with my body weight). Granted, I haven't had much time (any, really, I've been dealing with a shoulder injury as of late) to mess around with the settings since I bought it, but 65mm doesn't seem too far off. I weigh almost the same as you, as well. I found this video somewhat helpful. They don't really have specifics, but a general guide to get you started.
  8. I gotcha. Although this is trials, so anything is possible, lol
  9. Never really said I was all that worried about it, but I wouldn't exactly say that potentially dripping fuel on a hot exhaust pipe is "nothing". Are you talking about the brass piece that the tubing slides on to? Just my luck that'd snap off, lol
  10. I haven't been able to find a U.S. distributor of this stuff...
  11. Hi all, The exhaust is so close to the carb, that one of the vent tubes has actually gotten partially melted because the tubing routes right over the exhaust pipe. I was lurking around trialssuperstore.com looks for ways to spend money, and found this: Anyone know if this would work for my 2000 Rev3 270 with Mikuni carb? I assume this is a relatively universal part, but you never know... https://trialssuperstore.com/products/dellorto-vent-90
  12. You know now that you mention it, I have experienced a few mild kickbacks trying to start it. I hadn't put 2 and 2 together.that makes sense. Thanks for the tip. And yeah, I can imagine the look on your daughter's face. hilarious!
  13. Truth be told I haven't even really ridden it (except a few circles in my yard) since I bought it. I am in the habit of closing the fuel off, since my other bike tends to leak as well. By cleaning the crankcase, do you just mean pulling the spark plug and kicking the living daylights out of it at WFO?
  14. Yeah, really seems like I have either too much or not enough fuel. The plug is damp. I would say it's not soaking wet. I'm in Carmichael BTW, good to find someone local on here! I haven't even tried Prairie city yet. With the DMV closed, I can't get my bike registered (currently an Idaho bike), and AAA won't do out of state registrations.
