My 4RT ran more relaxed over long distance trials, had double the amount of engine revs if needed and carried a straight line up rocky sections. But I prefer 2 strokes, grip better on compact clay/mud, easier on downhills, less starting issues and easier to change direction in a hurry.
I've same bike, same year bike but a 250. Had it from new, the adjusters were set midway. No guarantee this is correct. You might need to keep check on the the fork pressurising during use, loosen the air bleed screws to release excess with the bike on its stand. Careful the screw doesn't shoot past you.
The 125 might kick over a bit easier than the 200 but none of them are hard to start, the only difficulty some have is the left hand kick start using their left leg, if so, try standing to the left of the bike and starting with your right leg.
If you've not ridden a trials bike before, compared to a road bike, they're designed by Martians. There's a lot to adjust to and a 250s 20 or so very tractable horse powers is one of them, along with very low gearing.
I had one but didn't try a bike in, I think the roof will be too low unless you ratchet down the front suspension/pivot the handle bars. Try before you buy if it doesn't burst into flames first.
To me Gas Gas's 4th and 5th gears seem the same, it pretends to be 6 speed. Beta's 1st is low enough to tickle through cobbly streams without using the clutch, but not much use in other sections. My Sherco used to rev too high in 5th on the road sections but was OK otherwise. My 4RT was best on the roads but a heavy numb thing on sections. For me it's a tie between Gas Gas and Beta for range of gearing. Let's see what TRS's turn out like.
Dell Orto carbs have a fuel adjustment screw, not air adjustment, screwing it in clockwise will weaken the fuel to air mix, the opposite to an air adjustment screw fitted to Kehein carbs. If it's a Gas Gas Pro I'm surprised it has a Dell Orto, Kehein have been fitted to UK models for a few years
For me, colder weather, hot engines being plunged into cold streams equals milky oil through condensation. I just live with it and change the oil more often.
I think the courier has a different sole. I've sidi trials and Forma Boulder boots the Formas are fine and an inch taller. Best protection I had was MX boots with a commando sole fitted by a local cobbler
Mine clack clacked the other week because the chains connecting link spring clip and outer link plate had vanished, allowing the link plate with the pins fitted to back out and clack its way against the chain tensioner, luckily no damage.
I've found a lot of the spherical bearings fitted to shocks are Polytetrafluoroethylene (ptfe) coated inside the outer bush with a chrome plated spherical bush in the middle. They're intended to be used dry but eventually the coating wears through, I've been told adding lubricant to these types of bearing can accelerate wear, but once they've worn through the coating there's nothing to lose by adding waterproof grease.
Need a rear tyre, any good deals on anywhere?
