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
You may find it hard to believe but I think you are absolutely right about not having another route and for all the reasons that you have listed .So to stop the farce of people stopping and observers allowing a 3 when they clearly fived it because they feel sorry for them just make the event stop allowed and there won't be any nonsense of making the rules up as they go along or perhaps men can be women depending on who is deciding. Its all very confusing, as they say rules are made for breaking. Best wishes Alan.
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.
I understand your concern about ruining the event I am not suggesting two lines just have an exit point in the section before the super hard stuff for those that clearly are not at that level of riding, it would save time for all and be less of a farce. The real point is trouble with all the stopping in the sections in a supposedly no stop marked trial the top riders can keep the bike going because they have the skills but also because of their fitness level being higher than the average rider. The two routes suggestion is only based on that or the easy way is just mark it stop allowed and the same at club trials that are run as no-stop , all I seem to see is people stopping but the results do not show those fives. To me that is just a farce what is the point of the rule if it is that flexible IE whatever you fancy.
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.
@lemur I Absolutely agree with you regarding the points you make although speaking specifically on the SSDT 2025 out of 280 odd riders a lot of the sections over the week are really only suited to about 25% of that number hence the constant stopping that is seen in the videos perhaps it is time the vast majority of the entry were given their own shorter more manageable sections within the same areas marked out for the 25% that actually can make a good attempt at the present more challenging route. that is obviously designed especially to suit approx 5 riders who are fighting for the win.
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
The 225s are rather tame. The jerkiness could be a whole number of reasons. Poor carburation, a bad ignition or you could just not be accustomed to the type of throttle response trials bikes provide. Are you coming from a road bike or a mx bike?
Has it got a flywheel weight added? You can tell if there's a 10mm spacer fitted between the casing and the flywheel cover. A flywheel weight is usually added when converting from 125 to 225 and helps to smooth the power out. I remember Kev from GGUK used to run 2 flywheel weights
There should be a few posts on the forum here for 225s. 9/48 is more 125 gearing but is rather low for a 225 or 250. It could be the person put a 225 kit on a 125 and didn't change the gearing. Gearing up may help
What's your intentions? Build a genuine replica, or a modern pre 65? If you have the original steel rims you could get them reconditioned and keep the bike original. Regardless of the rims I wouldn't waste time with anything other than SS spokes. Expensive but worth it if you intend to keep the bike for any amount of time.
Traditionally the spring/open side always faces inwards, but ive seen a few engines (some older Japanese stuff) that specifically call for the reverse on the transmission oil side.
As above, I think I remember another post from yourself where you acknowledge your bike doesn't have the original swingarm, so it may not be an 04 onwards swingarm. The pro model came in 02, so you could have the 02-03 swingarm.
I prefer 'turds' to sealant, Ive had gashes in the sidewall of tyres sealant wouldn't seal in a month of Sundays. Sealant/turds are ok so long as you catch a puncture before the tyre comes off the rim. If it does come of the rim, you will be pushing from that point on. Guys at the ssdt carry a front tube, which will do the front and also the rear at a pinch, and the only reliable way to get a tyre back onto the rim out in the field. If you ride relatively sensible this however is rather unlikely. A throttle cable is also easy to carry, but again very unlikely to break one. Once I caught a coolant hose on a rock and split the tubing loosing all my coolant and I didn't want to risk riding the bike any distance after that. This was on an sy250 which were known to have vulnerable hoses
The stop clock you see on tv would not be the official time being used, but I also can't see trials using anything more sophisticated than a guy on the floor with a stop watch. I remember a year or two ago Marcelli got timed out once despite the stadium/tv clock still showing he had 2 seconds left. I rewound the footage and he was correctly timed out, the tv clock was slow to start. Anything optical I doubt would work as sometimes the riders exit the sections by jumping off the last obstacle in lots of different directions. I seen last weekend Andrea Rabino lost out to Berta by something like 0.1 seconds, it was definitely less than 1s. I highly doubt they are timing riders to that accuracy.
Im still undecided whether I like so much of a time element being involved. I get the 5 minutes total time to ride 5/6 sections in the first round, but when it gets to the final and they have ride the section forward and backward within a minute, I'm not so sure. Busto had a great ride last weekend on a section even Bou fived and got timed out by 1 or 2 seconds. Then there's the element in the superpole round that if you five the last section at the start you can beat the guy that fives the last section at the end because he spent more overall time. I think Raga used that to his advantage in Barcelona and ended up winning superpole
Don't take it personally about the normal thing it was me that prompted you to use the word normal in what I posted , probably because I am old and as we are talking specifically on a trials motorcycle forum about a 2 stroke engine then I tend to talk about the bikes including what used to be the norm which was a longer reach plug , if you go back to the 1980's you wont find too many 2 stroke trials motors using a short reach plug which is a relatively new thing in the trials bike world . Outside of 2 stroke trials motors of course a long reach plug should not be referred to as a normal type , al though having said that I must say every petrol engined van or car that I ever owned in my 61 years never had a short plug fitted and so perhaps I can excuse myself for calling long reach the normal ones. Enjoy riding your bike. Regards Alan.
And if you go back to the 60s, 2 strokes such as Villiers will have short reach plugs 😂 Fashion I guess
I personally would be for that. Trials is comparative, so who cares if we are all running £140 michelins or some cheapo glorified trail type. I even think trialgp needs taken down a step via tyres, but that idea isnt exactly new. The problem is trying to convince the prima donnas of your class who will scour the end of the earth for every last ounce of performance. If you even suggest they will only be able to ride up a 3'11'' step as opposed to a 4', they will tell you you are ruining the advancement of the sport
