My Montesa came with an addendum to the owners manual detailing how to prep the bike for competition, it was in the crate right from the manufacturer, so I would ask your dealer if they scooped it or if they can provide that information. ... as for is it OK to remove the fuel tank vapour pollution control measures, that is likely a personal choice, the engine won't notice any difference. I owned another 4RT that was stripped of parts almost beyond reason by a previous owner and it worked just fine.

If it's anything like the rest of the world, pre-entry started because of covid rules and will likely remain because pre-entry is of huge benefit to the people that organize and host observed trials competitions. The only people that resist pre-registration are the ones that don't take entry to the event seriously and don't care if the event is successful or not, it's all about not wanting to forfeit the pre-entry fee.

Do Not wear loose baggy clothing and boot laces that can catch in the moving parts. Proper trials riding boots are every bit as important as a helmet considering your first crash will likely be at crawling speed. The boots also work great for rough terrain hiking and chainsaw work if you don't end up using them for riding.

Find some old guy that has a great place to ride owns 2 trials bikes and does nothing much else but ride and wrench trials bikes 👍 How do you feel about crashes because that is likely to happen, if you are in the habit of participating in rough sports you will likely have no problem. Riding a trials bike on trials terrain is a full body workout if you are doing it right, that will surprise you.

Want to know what will happen after you put lighter pressure plate springs then required in your clutch <- it's going to slip in high gear ranges, same as if you leave 2 of the 6 springs out. Rhetorical question but dimpled steel clutch plates in a wet clutch leaves more space for oil between the plates, do you believe that scenario will make the clutch grab stronger or slip easier 🤔 and with dimpled plates having more oil between the plates and less surface area contacting the friction plates, will that make your clutch feel any lighter to pull at the lever, I think not. Throw in some lighter springs and you have a formula for inducing more clutch slip.

What model tire exactly, is it a tube type tire that you bought? that would account for it, tubeless rims are different profile. ... if it is a tube type tire sell it to somebody that rides an old TY.

The problem you are noting with the Beta 4T throttle response is they fitted the bike with a CV carburetor. Vacuum operated carburetors rob engine intake vacuum pressure to operate the carburetor negatively effecting both the throttle response and the engine performance, in PGM-Fi fuel systems 100% of the engine vacuum pressure is dedicated to intake of air & fuel, Fi does not exhibit the throttle lag and occasional misfires inherent to the CV carbs normal operation.

Yes that normal trashy clutch sound in neutral the 5 plate Montesa clutch does not exhibit, the TRS o-ring fail was very early after receipt of the bike, was leaking down from the start. Fortunately I rarely have clutch problems with any of my vehicles, that tractor lube works perfect, you just never even tried it to know better.

Yes 2 and experienced a failure in a TRS clutch O-ring already. The clutch is not up to par with HRC Cota 315 or 4RT, I have to keep it engaged or it sounds like a bag of bolts.

any particular reason you made that a reply to my post or is that just a habit 🤔

Personally I think you are trying to improve the best clutch in the industry. Hasn't been mentioned yet but there are 2 types of friction plates in the Cota clutch, 3 corks and 2 paper, the consensus was the paper plate gives the clutch more bite, or absorbs less oil and exhibits less compression, depending how you look at it. Key to making the clutch pull lighter is not to weaken the clutch but to improve your clutch actuator leverage at the levers, the further you hold the lever out from the pivot point the more leverage you have against the hydraulics and the greater your friction range is.

It's a well tested and proven fact that cyanoacrylate adhesive is far superior to bung plugs when you want to field repair a slice or puncture in a trials tire, particularly if it is in the sidewall of a 2 ply trials tire, plugs will just make a mess of the damaged area when it's a sidewall split.

... no dude that's just plain stupid.

You can fix most problems with crazy glue 👍

If anybody wants to trash their expensive soft compound radial tubeless competition trials tires after one use, you can throw them my way. Even the worn out tires work good for winter riding after you pump about 600$ worth of carbide grip studs into them 😎
