  1. In all likelihood there will be more then one capacitor involved, the big one connected to the fuel pump acts like a battery and would almost certainly be dedicated to the fuel pump which is the highest draw on the alternator.
  2. How do they prove negligence unless they were being held under water by the land owners 🤔 that's the part I can never figure out.
  3. Make sure absolutely everyone signs the 'I'm not your mommy' waiver form, everybody that didn't sign is trespassing 👍
  4. Non graded bearings will simply never be as good as a better bearing even when you first install them, that's a reality, will they spin your wheel around and around, yes and maybe even a little bit sideways give or take. Guess I'm saying how do you think they come up with 5 grades of deep groove roller bearings and then there are the ones y'all are buying at 4 bucks each and not graded at all. Wheel bearings are obviously very important and highly stressed on a trials bike, was asked what I use and recommend and that's it, graded name brand bearings. I don't pay that much but I don't buy them in US, maybe it's a tariff thing
  5. Because there is only 2 bearings and they are carrying a wheel that is 27 something inches in diameter. Small amount of play in the axle bearing results in large amount of movement in the wheel. You can push thin oil into a wheel bearing with an insulin syringe and displace the water, might be wise after your next deep water crossing, makes them last longer.
  6. So you figure a 4$ roller bearing with only 7 balls and zero claim to tolerance is as good as the one with 9 balls, costs 4 times the price and meets a high tolerance spec 🤔 interesting. Yes you need to keep the water out of any roller bearing, that is what the grease and oil does, it displaces the water. ... if it was for the track idler wheel on a 1968 snowmobile I would agree with you.
  7. You are going to find bearings have a precision rating, low numbers are low quality, higher number ABEC rating cost more. Same tool is good for pressing in the new bearing, use an old bearing to push the new one in, works slick.
  8. SKF from a local being supply 6 or 8 at a time. You can buy different specs, expensive bearings have more balls and tighter specs. ... made up a puller to change them super easy, the steel sleeve to extract the bearing spacer is cut from a used CO2 canister.
  9. If you grab the tire by the front and rear and give it a sturdy wiggle rotating action about the vertical axis and can observe any change in the chain slack, that is a clear indication the wheel bearings need replacement or the swingarm bearing needs attention. Bad bearings also contribute to reduced braking. I end up replacing wheel bearings more then chains and that is buying the higher quality bearings ymmv.
  10. If the chain tensioner is doing something when the bike is at rest with no rider aboard you are good to go, if the rubber block is touching the swingarm at rest that's not good. ... so far this year alone I spotted 3 bikes with the axle set crooked and I noticed it because the chain tensioner was doing nothing when they parked their bikes. Make sure the axle is good and tight and that your wheel bearings are perfect, wheel bearings wear out fast.
  11. 😄 I think he is talking about the rider with both feet down and picking the bike up by the handlebars 🤔 looks like me except I can't pick a bike up by the handlebars.
  12. Wait 🤔 you lined an aluminum fuel tank because it was rusting?
  13. CV carburetors operate off intake vacuum pressure that is literally robbed from the engines intake stroke. Key to making a Beta 4T respond as well as a Montesa 4RT would be to install PGM-Fi instead of a carburetor and the vacuum operated fuel tap. PGM-Fi self adjusts to any altitude and air temperature changes and the engine intake vacuum pressure is 100% dedicated to engine performance, by comparison carburetors basically suck.
  14. This right here is why I no longer want to check at an important trials event, far too much ambiguity around the rules and the rules keep changing to advantage the entertainment of the near non-existent observers. The solution to the problem is in the building of the section, you can build a section that is suited to a no-stop ride and you can keep the perimeter tape far enough back from the ride line so that it never becomes a problem of somebody wanting or needing to cross it, you can lay out a section short enough to easy be ridden in an allocated time, or you can make a section so long that nobody can complete it in time.
  15. Montesa 👍 Viva! "Meets current EPA standardsModels sold in California meet current CARB standards and may differ slightly due to emissions equipment"
  16. If a trials bike is going to need to be emission spec where you ride I think you are looking at a Montesa or something electric.
  17. I think you need to maintain that it is not intended to pass EPA road specs any more than a new chainsaw or lawnmower would pass road vehicle EPA rules.
  18. Tires are stamped 'for off road use only'. There must be a way to import it or your feds would never be able to collect the outrageous tariff that is unique to your country.
  19. I bet when you push the brake pucks back into the calliper fluid will now go back up into the reservoir, if you did that first it might have cleared the hole.
  20. When you remove the brake master reservoir cap and force the disc pads full width apart did that not force fluid back into the reservoir? If not then you found a problem.
  21. Not considering population density, 287 people per square kilometre in UK vs 38 per in USA and only 4 people per square kilometre in Canada. UK has 7.5 times the population density of USA and 71 times the population density of Canada. UK has exponentially fewer places to ride, not much relative distance to get to anything and a lot more trials riders. I seen a Jotagas once.

    TY 175 fork

    If only classic TY had teflon coated bushings in the lower legs to replace, but sadly they do not.

    TY 175 fork

    Triple trees limit your options to run larger stanchion tubes, the stock steering head bearing is the weak part. Steering head bearing upgrade to taper bearing is relatively inexpensive and gives you the most bang for your buck. ... if you could devise a way to run a fatter axle and larger bearings that would go a long way to stiffening the front end, it's not hard to twist TY175 forks. Super important to replace the stock wheel bearings frequently to maintain suspension and brake performance.

    st 125 2004 stator

    Simple answer is yes, stators can be rewound, very often by a local business that specializes in repairs to stators and starter motors.
