I had recently my bike at the technical inspection to get it road registered after the rebuild was done. The bikes origin is from Torino Italy so I had to go through a §21 as we call it which means everything was tested. The brakes are capable to lock the wheels and the bike could be stopped on the road in suitable length. I think it depends beside the correct align between drum and shoe also to the right pad material.
Mmmh I don't know how bad your brakes are. The ones on my bike work astonishing well having still the chrome. I use original brake shoes (over 30 years old NOS) and had them aligned to the drums, which was quite a job. The outcome is what I need.
If you are braking with the wrong area of the brake shoe you can get very little braking power. So I recommend too to look up how well the shoes fit to the drums.
There is the statement that all Beta 4stroke models get the injection system Beta had already developed mounted to one Enduro model in 2015 due to better performance and the Euro4 regulations ...
Would be interested in a 4T Beta too the new model is fitted with a injection system no carb anymore, thus starting should be easier but furthermost no issues while riding in the mountains.
I'am more an old style rider and too "just" have old bikes, but a 4T Beta Mmmmh very nice.
The older 250 and 300 4T that I have tried were both easy to start, much easier then Bultacos or SWM.
No option for me too expensive but there is the issue of the very low € compared to a high £.
The same price in € and if as said every else is still working well not too bad. The model is getting rare and original spares to the 199b are very expensive (beside most crappy replica parts). I 'am afraid of issues because the bike had probably stored too long in the wrong place as there is heavy corrosion visible on strange places ...
No buy without having a very close look to it and too a roll out ...
Countersunk serrated washer are very OK, they are called DIN 6798 Fächerscheiben Form V = versenkt as we name them, they should be easy to get, here one address were you can order just 100 at once ... https://www.wegertseder.com/index_prod.asp
They work best. Nowadays you can use countersunk screws with Allen (female) head which are easier to thighten and loosen again,
A sidewise run out of 1mm is still Ok, while 3mm is too much.
A run out to height here also 1mm is OK, tires have already a run out of 1 - 2mm, a good workshop will mount the tire so that the run out of rim and tire will be compensated to each other.
Anyway as it is a trials bike I guess there are not so high standards as you can't ride very fast as with a road bike.
So a rum out of 2-3mm might still acceptable in both directions. I personal don't like it and gave the wheels of my old bikes to a professional "Radspannerei" that trued them, a small amount of bucks and as they too check the tension of the spokes worth to spend,(10 € per wheel). I gave them just the wheels and axles to save money.
There are so many different shapes for Trials and for MX bikes. Some mich really suit a rider why not. I am not an expert in handle bars I always buy the same models I'am personal used too. Tomaselli and Renthal while the Tomaselli is a tad flatter and less bend. The Renthsl is very similar to the old steel handle bars that came with the bike.
Anyway the last twinshock I purchased had a MX style handele bar mounted. (It's an old style handle bar even approved for street use). I personal felt uncomfortable with it. The bar is much more bend backwards. So I changes to a Renthal 5'' and everything was OK again.
The custom made piston is of course expensive then a bought serial nut not so much. There can be more difficulties and even costlier.
When the bike is a good runner, brakes are OK, so suspension and of course all other engine components and the ignition. Get a new one, they cone too with piston pin, rings ... (just my 2 cent opinion)
Mmmh ... mud sections you do not find everywhere that's a fact.
It seems to me that they show up less as they don't fit in new trials and are ... well ... more dedicated to classic trials and the past.
Anyway when a three is a zero it's OK to me, here I might be in the minority or the only one. I need some time to get used to it, then it's Ok.
What I hate is cleaning up the mess done to your gear and bike, too the excessive wear that comes with riding in the mud. You can't. Bend anything in soft clay but it dulls everything.
Yes probably not soaked, excessive oil should be removed. There is special air filter oil available. I recommend oil that can be washed out later in warm water with soap for cleaning.
You need Sodium Hydroxide or Potassium Hydroxid which you find in oven cleaner.
If done this with fasteners fort the front mudgatd from GasGas which were plated gold to fit to my Bultaco.
Worked great, but you have to rinse quickly to stop corrosion then the item should be polished to get the surface hardened.
I haven't done such a big part probably it's better done by a player.
There are some videos in YouTube too that shows how it works. Even a vid from Mr. Fredinghouse form West Coast Customs has a vid about plating removal from aluminium.
Another point when doing Motoalpinismo in the Alpes I have 19" inner tube with me to fit front and rear tire. In case of and this size fit's both wheels.
That inner tire is from Metzler too if this helps?
Using Metzler when I remember right and one the other there must be a Pirelli to the Michelin. Not sure what is mounted to the Smilla ... have forgotten ... does it really matter never came to this question so far.
This was the time were man were man ... just the 60's everything was possible in 2000 people thought that they should use a rocket for commuting to Mars and so on.
Time will tell there are as usual many option to develop a bike IF they will do a production run.
I haven't read the comment from KTM's CEO. I think when they will build one it will be a real KTM and the bike will use components from the engine to the suspension as with all bikes from them. (still a guessing just from history their bike development)
