  1. If I had a bad rear shock on my trials bike, I would replace it with a new one. Around here the enduro riders drop that much money on having their brand new rear shocks modified by SSS ... I'm trying to imagine the Mississippi area riding terrain and it keeps starting out like a muddy Saskatchewan 🤔 post pictures once you can 👍
  2. I service forks a Lot both my own and to teach other riders, once you've seen it done it's easy but messy. The fork slide bushings are what you are trying to keep good and will require regular replacement. Keeping the slide bushings good is key to keeping the fork seals good and there is no oil filtration so frequent oil change and cleaning will keep the whole fork lasting longer. Aftermarket slide bushings frequently need to be file fitted, don't just slap them in expecting them to fit, they likely will be too tight at the gap. Clean everything just as you would clean a gun.
  3. Coming from enduro bikes I honestly can't see the motivation for someone wanting a diminutive displacement trials bike. Riders coming from enduro sports even wear protective gear 👽. You should be using the trials bike to develop your control skills and learning to ride the pegs instead of the saddle and bars. Small weight and size rider on a trials bike is not a problem, bikes all weigh the same and you move around on them a lot if you a re doing it right. Don't grease the wheel bearings, replace them, makes a huge difference in the bikes handling and braking performance and the bearings are as cheap as bearings come. Buy the bearings from a local bearing supply and buy their best one if there is an option.
  4. Trials boots, you need them. Don't try to make due with your enduro/MX leg casts. Going super cheap on boots and the bike investment will give you a good reason to dislike trials riding. Get a good trials bike, learn how to ride it and then you can make lots of hill climbs the enduro guys will struggle or crash on, it's great fun.
  5. Found this a moment ago: "installed a tiny 12V Lithium rechargeable battery into the airbox 🔋 and a switch to turn off/on. Now when I hit the switch, I can hear the fuel pump energize and kicks first kick no problem every time."
  6. Look at it the other way around, they use ethyl glycol in brake applications so a failure does not result in oiled brakes, if it was not for that fact they would most likely be using mineral oil in all the hydraulics.
  7. I have a Montesa for sale, 3300 US$ is about 4500$ Canadian you could buy a lot more motorcycle for your $ in Canada, too bad for you it's so far away.
  8. Did some of the pre-filter get into the pump or is it 100% accounted for? Sure sounds like you found a big enough problem to account for performance issues. Water destroys the treated paper in fuel filters, makes it so fuel does not pass through as easy, replacement is the only reliable option if your bike ingests water 😐 like when you drop it into a lake. Fella riding a Vertigo Nitro here today (close to freezing temps here) after kicking his bike for about 20 kicks, I said sure sounds like you're charging the battery or you need a jump start. About 30 or 40 kicks it finally started and ran fine for the rest of the day. ... he's going to investigate the battery voltage situation as a possible cause. If yours has a capacitor instead they were reportedly less problem cold starting, which makes sense because a power capacitor charges different and is less problem in cold temps compared to a lithium battery lol one or two kicks should be loads enough if the alternator is any good.
  9. @mrskywalkerI don't read this as you being a novice rider, it's all about how good you are with throttle, brake and clutch control, that is what makes the most difference between your ability to pilot a small vs large displacement trials bike. You say you will be riding this in a yard that is relatively flat? <- then sound volume would not be a problem if you are riding a Montesa 4-stroke, they only bark when you rev them up to blast up a big hill, the rest of the time they sound like a Honda generator. Lots of ways to make a Montesa 4RT even more quite too, they come restricted for road use and you have to modify them to make them race ready as per the instructions that came with the bike originally. 1250$ even in US$ does not buy you much of a modern trials bike, that's about the price of a new set of front forks. To get the most out of learning to ride Trials you need the bike to be operating perfect, anything less than that will detract from your learning experience. Beta Evolution 4T is not an easy bike to start and keep running nice compared to the fuel injected Montesa, particularly once it falls over Beta 4T are harder to start and will have you messing with choke settings, Montesa has a tilt switch to kill the engine if it is upside-down because they just don't want to stop running in any aspect.
  10. Fuel injection pump submerged inside the fuel tank is located there for cooling, the motivation to keep lots of fuel in the tank is cooling. IF the fuel pressure became low the first thing I would check is the filter or filters plural if it has a pre-filter. I have seen pre-filters deteriorate in some fuel where the plastic bits get sucked into the fuel pump and second filter on other brands of motorcycles. Generally the canister fuel filter is under high pressure and the hint for that is it will be fabricated from steel and not thin plastic. Fuel pressure is generally tested by a gauge or by operating the pump off a battery and then measuring the fuel volume output over time. Pressure is fairly high on an injector pump, you are talking about 60psi range. Service manual is sure to tell all about it. From my experience with Honda/Montesa Fi the fuel filter is part of the pump assembly and not available as a separate part, the cost of the pump and filter complete is about 1000$ to replace. ymmv "bike runs perfect once it’s going" Once it's running the electric fuel pump is being powered by the alternator and not exclusively by the battery, that's why I recommended check your battery voltage when it is cold and compare that to when it's running. Montesa/Honda runs 100% off the alternator so it has a relatively huge alternator plus a big capacitor to spin the fuel pump.
  11. 🤔 thats' a fuel injected bike, poor start could be low fuel pressure, pretty sure it has a battery? low voltage at the battery could cause low fuel pressure, fuel injected bikes in general you should not need to mess with the throttle much for cold starting, on some like the Montesa that even messes them up and it won't start unless the idle is spot on. check your battery voltage when it's cold might be worth a try, when the bikes warm the battery is theoretically charging.
  12. Had a phenomenal new Trials rider here today, first day out riding serious terrain and he's already acing expert level stuff with very little coaching. He was our third place champion at this years GnArden hard enduro and has only ridden big bikes previously, one day out and he's definitely addicted to trials riding and the concept of riding sections now 😎
  13. A friend riding a 2023 gas gas 300 experienced the exact symptoms today, it was like omg and then he could hardly make it back to the house, pulled the carburetor and the low speed jet was completely plugged. We ran a thin wire through the hole and that totally fixed it.
  14. Air leak after the carburetor could do it, starved for fuel at the emulsion tube inside the float bowl part of the carburetor, faulty bottom end seal.
  15. Video does indeed make everything look flat and easy and from what I've seen hard enduro riders just starting to ride trials bikes are not afraid to try hard stuff, fact is they show nearly zero interest in doing easy stuff. Put a Jake Stapleton on either a trials bike or an enduro bike and he will point it up or down anything imaginable and make riding it for several hours look easy 😎 you don't tone your terrain down for riders like that you set out a pro line and watch the magic happen. Some advanced enduro riders are riding trials bikes competitively at the intermediate level within the first year on a trials bike. Ridership numbers representing all class of riders here is Way up in the last 3 years, including frequent practice day sessions, event support rides and in actual competitions. Given a venue the sport has seen a huge growth in talent compared to previous decades, that's the reality here.
  16. You don't know me from Adam. Y'all should lay off the Booze before posting!
  17. That part was very salty and this part "Sorry, that is an absolutely terrible attitude to have. You maybe dont realise it, but you are undenibaly driving people away from trials with an attitude like that." <- wtf
  18. And from your salty post, curious where the other 1% of your trials events are held, do you have a really big boat?
  19. Canadian here. And our CMA rule book states the following: Q-141 Conduct. (a) No riding on the course within ten (10) days prior to the event. Q-140 Scoring (section d Other Penalties) #3 - Practising on the course within 10 days prior to the event, and/or on the day of the event = Disqualification. Not saying it's a good rule but it is the rule if we want to host a CMA sanctioned event. @faussy yes, indeed my considerable experience with building trials events are unique to me and holy talk about attitude 🙄 I sure hope you do more then just show up to ride at events.
  20. Not so crazy, when I was 6 years old I taught a chimpanzee to play hide and seek and to ride my tricycle.
  21. Test between brown and white and then between brown and blue, I think blue is the light and white is the ignition if the meter agrees then white goes to points and condenser and blue to the light and horn. Next step would be to assemble and spin the motor to do a voltage test and see what comes out.
  22. If it's just a multi-tap transformer then the ignition will be the first and the longest winding will be the lighting coil output I should think. That way if the light coil burn out you would potentially not be stranded. Does that make sense with your meter testing? the lighting coil I would predict to have a higher resistance value
  23. How many wires are physically connected to the coil, we can't tell if the one white wire goes to the coil or just under it, if you have 3 wires exiting the coil that is potentially a combined lighting and ignition coil, only two wires would be just an ignition coil. Lighting coil will have measurable resistance separate from the ignition coil and one wire common to both those.
  24. The most basic wiring diagram that is similar to what you have right in front of you is a chainsaw. Wire it just like a chainsaw. search 'chainsaw points wiring diagram' the first images that show will work.
  25. That was my first thought even if it is not such a good idea. Securing or spring loading something to a brake line is just asking for trouble.
