Not sure about the v Mar and other linkage plates but all of the 300RR's have a more further back set than standard. Most of the csp, future, and other after market foot pegs are further back, however I don't know by how much in comparison to the stock 300RR. Hopefully there will be someone else who knows the actual answer to your questions.

Interesting, I just had my daughters Beta 80 apart for some tests of the fan and see this post. It was connected just as Reggie says... yellow is connected and earth grounded on the tab, the others two went to the fan and t-stat.

Hold on a second, I don’t remember telling you about the time I did that? glad to know I am not the only one! LOL

I remember reading a post where there was a little play in the PTB and when shutting off the throttle it would go past 0 and stall out, a small drop of super glue under the stop was used to diagnose the issue. I don’t remember 100% what the final fix was , but there was some talk about a washer as a shim and a few other options talked about. not sure if that will help but good luck figuring the true root cause out.

I wouldn't expect it to be, however I never done that before so don't know for sure. I have been surprised many times in the past at what I have seen happen with miss configurations, so wouldn't put it past it being able to.

MT43’s do have a very stiff side wall. Could be a factor on coming off a rim for sure. How hard he rides it might also be a factor. Good luck.

I think in this case as it's a trials rim on the 4 Ride there is a good chance it will be fine though. Still... good to know and will keep that in mind in the future. Thanks.

Pirelli MT43 is what I would run... probably run 5-6 front and 3-4 rear. If having grip issues on a 4 Ride maybe 4-5 front and 2-4 rear on the trail. Good luck!

Hard to say for sure but if I was going to try it I would not do the wire mod to prevent running the high fuel map. I simple terms your risk when not doing the full switch is if you run to rich or to lean. I would think it would run a bit rich maybe (best guess) and be ok... but I could be very wrong.

The step of disconnecting the white/green wire on pages 5 and 6 causes the ECU to use a different map to allow for the extra fuel needed.

It has been a long time sense I checked into it so I am not sure if this is the same thing I found last time but the concept is the same and maybe you can get the correct version for your usage. https://www.g2ergo.com/store/g2-throttle-cam-system/ or maybe http://www.rollonthrottle.com/specialorder.html I also found this one, but dosn't look like it would work for most standard Domino trials bike setups. https://www.motionpro.com/c/rev2-throttle

Unless they stopped making them they did have a company that did some various throttle tube versions. I will see if I can find the information on the company and post it if I do. if so I see you have two options, one is pick up one from them, or cut down a fast tube yourself. if you take a black slow tube and compare to a white you should see that the difference is just the diameter of the tube where the cable sits when twisted. You can custom your own by filing a small amount off of a white tube yourself. Good luck!

I like the Galfer pads myself. Had a set of the Gildfren S33 (Jitsie) and would say they where good but like the galfer a little more. My 2 cents.

That's good news. Sorry don't have any Grimeca to check for you... all mine are AJP or BrakTech.

As stated above back out the adjuster all the way before bleeding or you could try removing the lever completely. If it doesn't work with the lever removed you likely have a problem with the master cylinder.

Not sure why some say it changes things but I am at least able to give a guess. Not all of them have the same lever or the same pivot point location, this could change the stroke and leverage to give it just a touch more throw at the slave side. Best guess but at least its one possible explanation.

I re-read my post and thout... I should have made a comparison comment on my 2017 300 RR and my 2007 4RT 250 and my riding buddies 2017 4RT 260. in short, the differences are subtle between the 300 and the 260 if your not doing things like big hits or drop offs, with the lower end power being the most noticeable difference. And suspension being the second. However the differences in power and suspension become more apparent when riding harder. The diffrence between the 2017 260 and the 2007 250 is power and suspension and is more noticeable unless you have had the suspension update, then it gets more subtle but still more pronounced than the 300 to 260 comparison. hope that helps too. FYI - I LOVE my Montesa 300 RR! Best bike I have ever owned!

I would have to say that my order of best would start with the 300RR's on top, then the 2014 - current 260 Race Replica, next the 2014 - current Standard 260's, and then everything else. However a well setup older bike like my 2007 can still be a very nice ride in comparison to a stock older bike. It has custom setup suspension, fast throttle tube, and is the full power model. I find it much nicer to ride than a couple of 05's I have been on as well as its stock setup, after the updates. The why? 1) The 300's just seem to pull smother off the bottom, the twin map switch helps in the mud, the extra power feels great, and the suspension is just awesome. 2) The Race Replica 260's have the same extra power over the older 250's, and the suspension is a touch nicer in my opinion than the standard, and well they just look cool. 3) Standard 260's have a nicer smother and more power than the older 4RT 250's 4) Custom setup older 4RT 250... well custom to you, who can say anything more than that. 5) Everything else is just well everything else. Hope that helps.

Not sure where to get a Leonelli with the bullet plugs here in the US so I had to cut off the spade plugs and attach bullet plugs to one. After that plugged right into my 07 without issues.

Are you talking modify a 4 Ride into a 4RT? I thought they had different internaly spaced gears 1st to 4th and only 5th was the same, as well as taller suspension and different foot peg mount locations? As for everything else its mostly just tank, fender and other external parts to my understanding.

Maxima MTL 75, or GRO Extreme 75 are known good options. (Not sure witch you can get there) so I would expect the new Repsol 75 is about the same but still can get ELF here, at least for now...

Just because... FIM_Trial_Regulations_2018.04.22 States less than or equal to 300cc max for a 4T in Trial 2. (http://www.fim-live.com/en/sport/regulations-and-documents/trial/) Section: 3 MOTORCYCLES, CLASSES AND OTHER SPECIFICATIONS Sub Section 3.1 Motorcycles and Classes Paragraph: 5.

I would guess that most of them have been modified at least a little. I would speculate they all have at least a programmable throttle body on them, fast throttle tubes (white tube instead of stock black), anything removed that isn't critical to a competition (extra wires/harnesses, tubes, tanks, etc.), and have installed the riders preference of brake pads, fluids (engine oil, transmission oil, coolant, etc). Past that there is so many other things that can be done its hard to guess what else they may have gone for...

No I would not say poor rear brakes are common on a 4RT. Both my 07 and my 2017 300RR have great brakes. One of our other group riders has a standard 2017 4RT that is great brakes, my friends 05 has no issues as well. Have seen a few 2014 and 2015's at some events with great performance. I suspect its just a little ware in time or maybe some other edge case issue. Heat and the quench cycle worked great on one set of pads on my 07 that gave me a small bit of trouble when I first changed them but they set in quick.

I will speculate that because of the type of person Toni is he will push through and start winning again soon and it will be behind him faster than it seems. Yes it has affected him, yes this will cause the others to try harder, and it will be a bit more up hill than in the past but with how he is riding I am not convinced he is done just yet. My 2 cents.
