Bingo 👍 I build a national event when nobody else steps up to do one. Somebody has already stepped up for 2024 but if that event fails to materialize I will host one.

😎 Snow conditions have improved greatly and riding season is on again 👍

You're not getting it, have you never seen coloured Coroplast? It's solid colour corrugated plastic that is easy and cheaply cut into the shape of an arrow that can be used and reused for many events. We used white sheets of printed plastic with red & blue arrows and letters A-E printed under them for the classes for years and they were not near as visible and not as reusable. The plastic arrows can be stapled to a tree or stake or affixed to a rock face with a small amount of latex calking. It's a sustainable marker system.and it works.

What works for marking sections out in a desert does not equate to marking sections out deep in the dark forrest, that's why the venue should have some latitude over the section setup and materials used to mark the course, colour arrow gates has simplified setup for the builder and made it possible to reuse the markers. We have used colour arrow gates for a long time here now and it has been well received by the riders and checkers. Our NATC like format was applied by request of our champion class riders and we try to follow the rules our riders will need to be familiar with when they participate in a TdN, that's how I have tried to do it and profits from our competition events (small if at all) go to the Canadian TdN team effort. Some actually think that CMA plans or in some way contributes positively to the motorcycle Trials competition events they collect money from and to that I would just like to say 🤣

Never could care about the colour of the perimeter tape, that is usually sponsor branded tape and might be in any colour depending on who donated, it's the gate arrows that we adopted from NATC except for adherence to the actual arrow colour scheme. NATC says: "Gate arrows must be Black for Pro, Red for Expert, Blue for Expert Sportsman, White-with-black background for Support and green-with-white background for Clubman." imo Rule books should stay away from assigning the colour of gate arrows unless they are the same as the number plate of the rider going through them, that is the only format that is sensible for the observers. Example: if the rider has a yellow plate (or bib) they ride through the yellow gates, couldn't be easier. As an event hoist and builder I can easy obtain or already have ample quantities of coroplast for gate arrows in white, red, blue, green & yellow. Nobody likes green because you can't see it in the woods and black arrows will share the same popularity unless the black is on a contrasting white background. If I get lost in a section because the perimeter tape is a wrong colour 😕 I would be more concerned about my short term memory loss and gates should consist of 2 arrows pointing towards each other in pairs, not one arrow and the perimeter tape. ... and ya, CMA also doesn't stay up on TdN rules, our new rule book says time limits are suggested and backing up is a 5, but if you have a section time limit and the sections are set out so you don't need to back-up, who really cares! Sanctioning bodies should stay clear of making such specific rules on course setup and course markers should be left to the event builders unless it is to follow a sensible paradigm. CMA is jeopardizing their involvement in local club trials if they keep making rules that do nothing but complicate the hosting and marshalling of events, the organizers are going to insure their events through other options and imply rules that make sense for their own events and that is exactly what has been happening here in recent years.

"have done some basic checks on the stator resistances and voltages and these seem to be within a spec" More on that; what was the coil resistance readings, were they all the same and how are you measuring the AC voltage coming off the alternator? ... It's not suppose to be all dirty and rusty like in there 😐 and one thing you never want to see near the magnets and coils is metal shavings that can short things out. The ignition pickup coil produces a brief electric charge that is voltage amplified by the CDI and the ignition coil to generate the high voltage spark at the plug. The pickup coil has a resistance check but the CDI boxes on any bike is near impossible to meter or scope test, you need a known good unit to really be sure, that's why I like to buy trials bike in pairs. Without a replacement CDI unit you can only process of elimination troubleshoot whereby if everything else electric tests good then it must be the black box. Engine running backwards would have me checking to see if the ignition timing is way off or the engine is stuffed full of carbon.

Looks to be a really nice enduro version of a BSA 441 Victor Special 1966 -1970

Good, now somebody can explain what class I should ride in this year and what colour arrows I should be using because Black arrows is not going to cut it. CMA show 13 rider classes that will require a minimum of 3 riders per class for any event results to count, which would be fine if the average CMA trial could draw 80 riders but reality is that half that number of riders would be a significant improvement in turnout. Four separate Veteran classes 🤨 seriously! plus a Women class 🤔 so now we have a class for every age, gender and ability imaginable. This rule book was definitely written by somebody not in touch with reality, we (the people that actually put on CMA national events) adopted NATC arrow schema years ago, the rule book still refers to red on right and blue on left. Riding Lines – Championship – Black – Trial 1 – Red – Trial 2, Women, Veteran 2 – White – Trial 3, Veteran 3, Modern Classic – Green – Trial 4, Veteran 4, Vintage – Purple – Trial 5, Veteran 5 – Yellow - Championship – Black - Trial 1 – Red - Trial 2, Women, Veteran 2 – White - Trial 3, Veteran 3, Modern Classic – Green - Trial 4, Veteran 4, Vintage – Purple - Trial 5, Veteran 5 – Yellow

CMA rule book for 2024 is online now: https://www.motorcyclingcanada.ca/rule-book-2 As an event host I have some issues with the new rules so I'm sure other will too. ... still trying to interpret this part: " Front number plates are required for all National Championship Rounds. They may conform in size and shape to the outline provided by the fork tubes and yokes. Numbers are not required." 🤔

That's 5 micron 🤔 it takes some serious optical equipment to measure in microns considering the human eye can only see something 8 times that size.

Conrod has zero play, I'd roll with it. It will likely engine knock a little like an OSSA 🍀

Online manuals are easy but thank-you. Document the heck out of that part if you are going for a new engine, hopefully that happens. I'd be most worried about heat near the exhaust valves and would be inclined to take pictures of inside the top end.

Check that your oil delivery hole is not plugged, possibly even since new, somebody just now reported that issue on a 4-ride, & that would certainly account for an engine knock.

You got a part number for that shell bearing? 🤔 I think the oil pressure is mostly top end and you haven't experienced problems yet because it's built really well and the oil in the wet sump and splash off the cam chain was sufficient to stop it from imploding.

Snow was too deep to ride for a couple of weeks but conditions are improving 👍 at least I can ride the lake and the snowmobile tracks now, just wish I had made way more tracks. If you're planning on riding winter trails where there is snow accumulation figure on needing a trail groomer or two.

Hey Emlyn, I had one of those once, had to rewind the alternator coils when it burned out. The 12 volt rectifier you need is nothing special you can use one from almost any similar motorcycle, same with your rear brake master cylinder, should not be difficult to source either of those items. Worst feature of the bike is the air intake doesn't like deep water crossings, that's what eventually killed mine, try not to drown it.

Made a set of custom brake shoes for a friend that rode one of those, I used Thorndon XL elastomeric bearing plastic and it made the front brake powerful enough to do nose wheelies, unless you run them hot enough to melt the plastic, that was not so good 😆 Not saying I would recommend that exact modification unless you regularly ride in deep water, but it's worth mentioning that there is another way to approach the problem 🤔

Using mineral oil for any hydraulic application that won't end up oiling your brake pads is a brilliant move. To minimize the number of fluids that you use for maintenance buy Honing or Sharpening Stone Oil which is food safe mineral oil and excellent for lubricating anything that needs a light oil. Norton brand is what I've used for decades in all kinds of applications and it costs ~20$ per quart which will last you almost a life time if you only use it on your motorcycles.

You can do like I do and continuously ride the rear brake 😆 hard on the brake pads but at least you never lose track of where the brake pedal is.

The big difference between Saber and Dominator or Interceptor is that Saber 100:1 oil is too concentrated to use in an oil injection system.

I have used Saber in everything 2-stroke for many years with no issue.

Buy something built in this century and fitted with 4 piston front brake, 2 piston rear brake and most important it needs to start easy. For gear you will want an open face helmet, gloves, proper trials riding boots and a back protector is recommended or required once you plan to ride in competitions. To advance your riding skills fast you will want riding partners, ideally someone riding at a higher level than yourself that you can follow, plus a venue that features some challenging natural terrain. Trials bikes are among the most expensive motorcycle per pound you will ever buy but cost of operation is relatively low, they don't break easy and they burn relatively little fuel, however replacement parts like fenders and tires will be expensive. If buying used, plan on spend almost as much time servicing your motorcycle as riding it.

Too new to expect serious problems, I would check the plug gap or replace the plug, check the air filter for cleanliness and the correct saturation of filter oil, basically anything that would cause fuel to incompletely ignite in the combustion chamber such as the ignition timing.

On the up side the 4RT engine is designed to survive low oil pressure far better than a regular Honda engine costing near half as much, there are roller bearings instead of oil pressure bearings or on near everything.

If the Oil Strainer Screen is plugged the pump and filter will starve. I didn't see mention of the strainer screen outside of the Engine Oil Flow Chart pictured above.
