Keihin Jetting for 300.
Your TRS manual is pretty clear about what ratio they want you to mix at.

I think they're trying to prevent moveable ballast. They all add weight, they have no choice, but it's firmly affixed to the bike.

2012 gasgas txt 300 clutch slipping
75w light gear oil is pretty thin, so I wouldn't worry about that. The GG only takes 350 - 400mL (370 will get you right to the middle of the sight glass if you drain it hot and tip the bike to get everything out). I think you're in the US. My recommendation would be Silkolene light gear oil or plain old ATF. If the belray is motorcycle specific I wouldn't expect it to cause the issue with slipping. Assuming that's the case, pull the clutch out and measure it. It should be between 9.85 and 10.05mm. If it's way under the low end of the spec, that's your problem. Time for new plates. It won't be much over, because if it was the clutch would be rock hard to pull in.

Beta 2019 models? When release?
Sachs, Paoli. Equally yucky! (I'm still remembering my '13 that had Paoli's on the front, although I think the rear was a Sachs).

Beta 2019 models? When release?
There's little point in a huge redesign for any of the manufacturers now. We're riding the very long tail of trials bike engineering, where the 'changes' are all essentially fixes to any existing problems that crop up, or supply chain issues, etc. New manufacturers like Vertigo and TRS started with a blank sheet and the ability to pick and choose what they liked (or didn't) from the current crop of well refined bikes. They could also have thrown all that out and started over if they felt there was room for major change. The best they could do (which isn't a knock on them) in terms of innovation was really just the fuel injection on the Vertigo, and as we know they weren't the first to do that. Short of someone finding a way to shave another 20 pounds off a bike, I'm rather fine with small steps in refinement, as all the current bikes are more than capable. The cost associated with any major weight savings at this point is going to be prohibitive, so again, what are they gaining with huge redesigns other than a huge engineering bill... I can't think of anything. P.S. Beta could just make a lot of people really happy by putting some Tech forks and a Reiger on the bike. Hell, they could split those changes over 2 model years! Or even three, they could do one year with one Tech fork leg and one Paoli.

engine oil
Not to overstate what should now be obvious, but again (read the description and note the two quoted viscosities): http://www.silkolene.com/motorcycle/gear-oils/gear-oil-light/ https://www.motul.com/us/en-US/products/transoil-expert-10w-40 Etc etc. I think you get it now.

engine oil
I know nothing about the specific oil he's got, but plenty of people run motorcycle gear oil of 75w or 75w80 in trials bikes. Silkolene Gear oil light, Maxima MTL, etc. All work very well in a variety of trials bikes.
-
engine oil
Gear oil and engine oils are rated differently. The end result is that a 75w80 gear oil is roughly equivalent to 10w40 engine oil. A lot of gear oil manufacturers publish engine oil equivalency ratings on the products.

Well, there you go. I was wondering what the deal was with the Vandal, it seemed to have disappeared.

Have you not seen all the other factory bikes with automotive wheel weights stuck to the bash plates and secured with zip ties? High tech isn't really required. At one point they were using rebar on the TRS because, well, probably someone found it laying around..
-
Cant start up the bike
The Vertigo starts fine (first or second kick when cold). So either you're doing something wrong or there's an issue specific to your bike.
-
Gas Gas factory bike detail
It's the lowest place available to put weight. I suspect they don't mind the slight change in angle of the bash plate because it just forces the bike forward a bit if you end up resting on it at the top of big steps. Clearly the loss of a little ground clearance isn't a concern or they wouldn't do it.
-
Gas Gas factory bike detail
Lol, yeah. Just settings... of course the settings are applied to a one-off Ohlins shock no one else can buy. Although to be fair, in keeping with his 'we use all the supplier parts' quip, it is at least an Ohlins.
-
Arnau farre dropped
He blew out his ACL as I recall, he could be a very long time coming back, if ever. He did look good in the indoors up until he got hurt, so I hope he's ok. Athletes get paid (or as I imagine in Arnau's case, he probably just gets transportation costs, mechanics, support, etc covered) to compete, and if they can't what would you have their employer do? They need to get someone else on one of their bikes.
-
Gas gas colours.
Yeah, they're needed. There were two GG's released in 2017, the first was red and grey with big GasGas lettering on the seat. The second was the E4, which I believe was red and black. I don't recall ever seeing yellow on a stock GG in recent memory.
-
Beginning of the end?
Can we dispense with the absolutes? I think in this particular case, it wasn't. He was back on the bike within a month, performing at the same level just with reduced fitness. I think it's fair to give him a good period of time to overcome any lingering physical issues and at the same time reclaim full confidence, which always takes a hit after any injury.

oil change in TRS 280 RR
The current recommendation only became 'definitive' when TRS got around to inking a deal with NILS. Prior to that they spec'd ATF, which is likely what most people in the US use in it as that's what the importer still recommends. That said, any light gear oil like silkolene light, Maxima MTL, etc will also work.

2014 txt pro 300 stiff clutch,250 pro softer springs ??
As above. If you ride an easy line, go ahead and make the clutch as soft and progressive as you care to. If you're moving on to advanced techniques though, you want a clutch that hits harder, and you have to pay a bit of a price in lever effort to get that. An adjustable preload ring is the easiest way to go back and forth without messing with the clutch pack itself. Provided it's within spec, all you need to do is select one of the 3 settings, and the clutch will go from hitting like a hammer (with heavier lever pull) to being nice and, well, slow (with easier pull). They come on all the new GG's, but you can buy a Xiu ring.

Beginning of the end?
Bou didn't qualify well either, he dropped a mark. Not as bad as Fajardo, but he started 13th. So I don't buy it. Fajardo rode well.
-
Beginning of the end?
Bou aside, I have to say Fajardo's Saturday ride was inspired. He got Raga by 12 marks, which was quite something. Hopefully he can put it together a few more times this year. Busto on Sunday had a great second lap which gave him the edge over a very consistent Bou. I suspect the lingering back injury and lack of practice time are the biggest contributors to Bou not winning as per the norm, but often at this level it just takes one small hint of weakness for rivals to force their way in and start to exert more consistent pressure. I'd love it if we saw a regular battle for the top 4 spots.

Chain Tension & Wheel Alignment
Having the wheels completely true on a trials bike is completely unnecessary. Use the chain guide as a marker to find the places where it's really out, adjust the spokes, and call it good.
-
Busto and Fajardo to Gas Gas
Yeah, it seems that way if you ignore all the numbers that are 1's 2's and 3's.
-
Busto and Fajardo to Gas Gas
Busto wins. GasGas's collective heads explode as Bou goes winless on a weekend for the first time in I can't remember how long.

I'd suggest waiting. You'll get used to it. I can't ride the Dell'orto, the throttle is insanely heavy to me. Which is to say again, you'll get used to it.
