I would also go with the OKO, ease of set up over the dellorto & runs cleaner.

Apparently not, as the Beta is the best selling trials bike.

Have you cleaned the carb & blown through the jets?

Not a pro, though.

None of these points/comparisons you make are as important as how a bike feels to ride. Trying a bike is vital if you are thinking of buying.My advice is get the 250 which feels the most comfortable.

Don't overthink it, or spend too much time asking for peoples opinions on the internet. Everyones got different experiences. Start by having a ride on the bike you're thinking of buying, you'll soon know whether it suits you or not. An EVO 250 is the default clubman bike, i'd start there, get a test ride.

It is indeed a 97 JTX as mentioned above.

Problem there is you need the ultimate rider to make it work 😀

Is the correct answer.

Stators on these definately an issue. Also as you say, the fuel lines associated with the rear tank dont help. Certainly a model to avoid.

They all fit different, go to a shop & buy the one which fits the best.

Mine was like that from new.

Had this on a new Beta, the wheel had been built wrong & was some way off centre. Need to true the wheel to the correct offset.

65:1 is too much oil as you have seen when you open the throttle, I doubt this has anything to do with the knocking though.

The FIM dropped their proposal to make the WTC 4 stroke only, hence why it was shelved in favour of continuing 2 stroke development.
