  1. Picture of what you have to work with might be in order. From your description all it likely needs is bags of money and many hours of wrenching. I say no to period correct parts, unless they are used and in need of service it won't represent a significant cost saving to buy obsolete parts. Here's the problem; if you don't have a ride that works near perfect you will not enjoy the sport.
  2. Rim lock I would buy a light one, but my bikes are a lot lighter they all work if you don't pinch the tube mounting it and that rarely happens. ... I can easy spot the cheapest one there and that would work just fine.
  3. Want to know a Canadian backwoods Trials tire fix secret, the worlds best tire sealant is Fish Glue. I even used it to fix holes in an inner tube tire that has sheet metal screws in it for riding on ice and snow 😎
  4. Seen it done with sheet metal screws through the side of the rim and into the bead, but that's a bit backwoods.
  5. Almost shocking that rim has no hole for a rim lock, hole is typically not same size as the valve stem hole. For the tire to slide that direction it was under brake force Rim lock is a safety feature for braking because it might suck real bad when your brakes don't work.
  6. Rode 4RT for decades and only used the same all season hydraulic transmission oil I used in the farm tractors and excavator in the transmission. Regular Honda oil in the engine. Filters are easy available and inexpensive. Never have clutch and transmission problems even in winter sub zero riding 2T or 4T Using Kubota branded oil at the moment, check out your local farm supply
  7. You know you need rim locks or some other way to secure the tire to the rim when the valve stem goes crooked or disappears into the rim or gets sheared off depending on how you have the valve stem locked down, I put one side of the tire on and then push the tube in from the other side tube deflated, install the valve stem, rim locks are in place with the nut backed off completely, push the rim locks in by the bolt and nut when you are mounting the second beed, the rim lock is where you need to install the bead first then work around the rim to about the 3:o'clock position to finish mounting the tire. Don't need soap or water with mounting a tube tire except to test for leaks and to wash the wheel before you work on it.
  8. 4T Trials bikes typically have separate oil for the engine and transmission, the transmission oil needs changing when it contains water or the clutch will cause problems as the transmission never gets hot enough to boil the water out. If you are doing lots of water crossings or power wash your motorcycle regularly you will need to change the oil when the clutch starts to make strange sounds or act up. ... They only hold half a litre in each reservoir so it is not a significant cost to change out. The separate engine and transmission oil is a great design because it allows you to use inexpensive hydraulic oil in the transmission suited to wet clutch applications and change it frequently. Separate engine oil enables you to run high tech multi-grade engine oils in the engine if you wish without causing wet clutch problems associated with friction modifiers. Water is slightly less of an issue in the engine oil where the oil is in contact with very hot parts but it has a paper oil filter that will have issues if that contains water. ... Do you power wash your bikes, operate in a wet environment and do lots of deep water crossings? <- you need to change out the oils and filters more often compared to the guy riding a dirty dirt bike in an arid environment.
  9. If it is a radial it will have an R stamp in the tire size, and/or clearly state Radial on the tire sticker. If it does not say Radial or R then it is not a radial tire. Radial tires typically cost more. You can safely run a rear trials tire in either direction on a trials bike, happens all the time. One rim lock might not even do it, you might need two rim locks if the tire does not fit the rim tight, two rim locks on the rear was common in the days before radial tubeless tires became common. If the tire slides on the rim it will typically shear off the valve stem leaving you with a tube that can not be patched. All of that just to run a cheaper tire that performs less, weighs more and is far harder to install. Tubes and rim locks are no longer cheap and you might even spend more coin to convert to tube type compared to just running the correct tire. Tubeless rim and tires have a different bead shape compared to tube type.
  10. When I ran tubeless tires on a tube type rim they were almost impossible to bead suggesting the tubeless tire rides tighter on the rim, going the other way around you will have the opposite problem; about the only way you could do it is to glue the tire on the rim and that would both seal in the air and stop the tire from moving on the rim. Is the tire radial or bias ply? Best to buy the correct tire and better to run a radial.
  11. Locks only stop honest people -> 'out of sight out of mind' Best way to secure a motorcycle in a garage area where it might be stolen from is to put the motorcycle inside a locking container.
  12. If it has 'top hat' washers then it is is a floating brake 😐 the type of disc brake where the disc needs to float to centre the disc between the pads. To do that the disc needs to float side to side and not radially, if the washers are worn in 2 spots radially you can loosen the retaining blot and rotate the top hat washer so it wears in a new place.
  13. 🤙🏾 I was there for a month trying to rent and ride there but sadly it never happened. Terrain looked awesome for trials riding in places I'm sure you're not allowed to ride.
  14. & Aloha what island do you ride? 😎
  15. Determine if your clutch operates on DOT brake fluid or thin Oil Determine if the problem is in the Master cylinder, brake line or Slave cylinder Replace parts and install is fairly easy requiring very few special tools outside of possibly a big plastic medical type syringe similar to in the picture below Easiest way to fluid fill is generally from the bottom bleed vent screw
  16. Did it leak out where you can see it or inside the engine casings?
  17. 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.
  18. 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.
  19. Make sure absolutely everyone signs the 'I'm not your mommy' waiver form, everybody that didn't sign is trespassing 👍
  20. 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
  21. 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.
  22. 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.
  23. 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.
  24. 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.
  25. 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.
