The Beta out turns and tracks better than the 4RT. The 4RT is amazing when the front tire is in the air. No matter what bike choice, (Repsol, 260 std or 300) the suspension is better on the Montesa. The Beta starts better. They are both pretty bulletproof bikes. Of course the ease of FI is very nice on the Cota. Their is a noticeable weight difference and ground clearance issue on the Cota. Plastics are way cheaper for the Montesa. If you want a bike to last more than a decade, the Montesa is it. Probably an unfair, but truthful comparison is I know more riders that used to have a 4Rt than have one now. Mainly the Honda lover`s stay Honda lover`s.

Back to square one. The pilot circuit has two passages. One comes out under the slide, the other in front of the slide. These have to be clear and free flowing.

9 0ut of 10 times the problem of all motorcycle problems is a plugged pilit jet.

Read agsin and again.

That is exactly one of the issues of the current organization. The sections become the same style as the local club only sets the boundary ribbon, not the splits. Bring back the technical turns, but the riders would want to stop and hop.

Well that really was the best move for the sport.

Usually you would lump Beta and Montesa, for build quaility and more of a stable ride. Sherco, Gas Gas and TRS would be more on the fringe for the younger hop and bop crowd. I prefer the Beta, but would go with the TRS for build quality in the hop and bop types.

Did you get the correct spoke? There is like 4 sizes , just a little different.

Buy the newest Sherco possible or any year Beta.

Actually you are partly right. I tried lot`s of gear choices. It came with 10 cs, I tried a 9 and 11. Worthless. I even rode for awhile with a 10 and 39. The problem on the Beta is the gap between 1st and second. So I just went for gearing 2nd. With 9 and 44 I usually never use first, but every so often having a super low first works a treat. (The 10 and 39, first worked great but again second became worthless.)

TRS is like the new Gas Gas. The riders looking to better themselves tend to dress the part. My son has gone this way and wears the skin tight pajama`s. But no TRS gear yet. Our club special orders our own club gear every year. Jersey, pants and Jacket.

Actually it is just the opposite. The new bikes come geared fairly tall. They spin due to this style of gearing. With the gearing lowered, once you are on the throttle you will not spin. You are now tracking at a slow pace.

My son was about the same,went from a Sherco to a 300 Beta 4T. He absolutely loved the four stroke power and the engine braking. We also have 10 4rt’s at work that he rides quite well. Last summer he switched to a TRRS 300 RR. main reason was weight. If you hop all day the 4 strokes are just heavy. Good luck and have fun. The 300 is a great looking bike.

There should not be any play up and down, some maybe side to side. Even worse the earlier Sherco`s mains would spin in the cases.

The 250 is a low compression bike in the first place, look at the Factory specs. I run 9 and 44 sprockets. Not for a low first, but for a great 2nd gear. My 3rd gear is exactly the same as a stock second, and 4th is just barely taller than the stock third. It gives you such a broad range having 4 workable gears in a section.

You are more correct in that than most people would like to admit. I had a cota 200 stuck in the corner of my garage for 17 years until I was old enough to ride vintage events. It was like cheating as it had just enough power and handled well. Actually the stock Montesa makes it`s power in the wrong places for mere mortals and that is why it sucks in mud. And speaking of Pat vs a guy named Frexia, the bike Marc rode was not even close to a stock bike. It was quite exciting to get to watch both riders those two years. It really did push Pat, and he worked for the win the second year. Last Sunday was quite fun when we had about ten guys of all levels try a very hard corner which included many issues. First it was a very fine line, it dropped down and then suddenly had an up. all the while being a hard left turn and ended in a floater off a small wall. Not large or dangerous, just very hard to put it all together. (And just a little slick) The results were interesting. A 250 and a 260 4RT always spun too much, but a 300 4RT did it ok. A TRS always spun. A Beta 300 4T always spun out and a couple other bikes struggled. My Beta 250 did the best, between the lower power and 9cs and 44t gearing made it work the best. So yes, it is not always about power. The Montesa riders were quite different levels, clubman, expert and Champ. To get back to the OP real thoughts. He thought the Montesa had more inertia than the Sherco. Reality very good riders on a stock Montesa always hit lower on a splatter than on a similiar two stroke. That is coming from riders that have been there done that. Not from my opinion. I have witnessed this watching our top riders through the years. So yes, a stock bikes needs help if you are pushing your limits. (Not everyone is super human.) I also have seen Bou, Busto, Fuji, Frexia, and the most interesting Karlson make the Factory bikes just fly. Not on video, in sections that I have scored. Those bikes flat out run really well. Truly amazing riders. But I still believe the two stroke is better.

When you had the flywheel cover off did you check to see if your main bearings ars bad? Just grab a hold of the flywheel and check for up and down movement. If your mains are bad the seals will never seal.

The 4RT is really strange as it hits at just above idle and then it does rev out well. The initial hit is hard to control on clutch release. You can watch most 4rt riders as they will spin in places where most two stroke riders don`t. It`s always interesting to watch a Bou video because the sound never matches what you think the engine should be doing. And yes, if I had a 4RT I would invest in a pipe!

And why do you think only 4 Montesa`s entered the British Championship?

So what are you trying to figure out with the weight of mass for?

That is why they came out with a 300 instead of a 250. Do you really think a 300 4 stroke makes as much power as even a 250 two stroke? No , not even close.

Yep. The stock one does not sound like that one. That is why the sound is covered up!

You need to spend some dollars if you want a stock 4rt to have some punch. https://www.termignoni.it/en/product-category/montesa-en/ None of the good riders on Montesa have stock machines. Also most of the top riders have a stronger clutch to create a quicker inertia.

I would have liked to see a pic, before you cleaned it up. From the second picture it looks like the cylinder was leaking into the water jackets. I would pull the cylinder off and have a good look at the piston and rings. With using H1R, chances are your rings are just stuck as Bel Ray products leave a real gummy residue. (I used to get all B.R. products cheap and loved H1R until I saw the insides of my motor.) You will need to remove the rings and clean up the grooves. So you will need a base gasket, and orings. Rings if you feel like it. Two things to check while going back together would be the water pump and make sure the fan is working properly. Good chance the fan is not coming on all the time. When they start going bad you can spin it to get it started. Good luck, I`m going riding.
