All types of SS are predominantly iron. You argue it's not stainless because it's magnetic? I would expect a ss spring to be magnetic, because the very act of cold drawing and then tempering makes stainless magnetic...

Yeah I did some quick calcs and they are very close, equivalent to about 1/2 tooth at the rear. The fact you already know you like the 51 and you aren't shooting in the dark, getting one made is probably the way to go. I take it you've tried contacting talon directly?

I don't have an EM so not sure what the standard front sprocket is but if you run a 10/51, it's virtually identical to 11/55, and I see above 55 is available. 11/51 is also very similar to 12/55. Not ideal, you would probably have to buy another chain aswell as the front sprocket, but an option albeit an expensive one

Only when you get to expert will you think the 250 isnt enough for you, so unless youre going to be making expert in the next couple of years id steer you towards the 250. Although if the right 300 came along at a good price, go for it, just be prepared to spend a few 100 on bits slowing it down. I actually think a detuned 300 is nicer than the 250, more torquey low down, they are just a bit of a handful up top if you get too aggressive with the throttle

Not an ossa expert but from a practical point of view I always find it easier to keep gloss black barrels clean than matt ones. The latter kind of get stained with mud

I would worry about any 2 stroke trials bike long term doing any sort of enduro. I dont particularly like 4rts, but you will at least know the gearbox and engine will stand the abuse

Had this happen to one of my ggs years ago. Once fixed you need to tie the clutch line to one of the down tubes where the exhaust comes out with a zip tie. As for rebleeding, what you have described is correct. There should be a bleed nipple on the banjo where it enters the clutch casing. Just bleed like you would a brake cylinder

Its a wheel bearing on a trials bike, what do you need high tolerance for? The water and dirt gets into the expensive one every bit as easy as the cheap one, and once it does they're done

Personally ive found wheel bearings to wear out no matter what brand or cost they were. Once water and dirt get in they are toast so I wouldn't put yourself out too much sourcing quality wheel bearings. Its the only bearing on a bike I don't care where they came from

I stand corrected

This is one event that will never go stop allowed, its never been stop allowed even when the world championship was. Tradition. The only two options are accept that brief stops are now the norm, or reinforce the rules to riders and observers that no stops will be tolerated. I don't think it's that confusing, or making up of the rules. Stop isnt allowed, but slowly over the years longer and longer stops have been tolerated. This isnt specific to the ssdt, IMO this is standard practice from club trials right up to the world championship before it returned to stop allowed.

Thats still two grades. The whole idea is to have everyone ride the same line, thats the whole point of the event. The guy who finishes 300th wants to ride the same sections that Dougie Lampkinn rode. Anyone who rides the ssdt knows exactly what they are signing up for. If they find it too hard, they don't return next year, and someone else takes their place. Putting in a route for people who find it too hard is what you do at your local club trial. Whether it's a 5 or not for stopping is up to the observer. Some will give it a five some won't. People have let longer and longer stops go unpunished every year since the no stop rule was introduced. Thats unavoidable. Whether one observer gives it as a five or not isnt really important, the key is to be consistent across the 300 riders riders through your section.

You suggest making two lines in the ssdt? The event is over subscribed every year, adding an extra line to accommodate the bottom half of the field would only dumb the event down

Not sure what the point is that youre trying to make
