They may not be correct compared to the stock bearings. I have had them in my 301 for 18 months and still tight as the bike was new.
That's as maybe, but I wouldn't think Honda/Montesa would spec full compliment if they didn't think it was necessary. Full compliment have a greater load rating I believe............
Two bearings in each end of the dog bone for a total of 4 bearings plus 4 seals.
It is VERY important to also check/replace the two more bearings that are in the swinging arm, these,if neglected can result in a very expensive repair.......

Whilst agreeing with the above statement I would be wary of

All balls has the cheapest complete bearing kit.
May be cheapest but they aren't the correct needle rollers in their kit - should be full compliment type..............
It's funny how your article blames valve sticking on the lead but in the end of the article when they mention :"how to prevent the valve sticking" they don't even mention to stop using lead. lol they completely change the subject to "temperature" so basically they re saying is a temperature problem and not lead problem! thanks for the article though
It is indeed a temperature related problem and I am glad you've now read the article properly. Whilst you may well get away with using AVGAS on a high revving hard working engine just be warned that you may well have the problems mentioned if used in a trials engine that is just pottering about at low revs - I know I did.

Have you ever asked your self why they took lead out of every single fuel but did not take it off aviation fuel??? safety is priority over pollution so they made exceptions for aviation.
As you say, safety reasons due the problem of using Ethanol as a substitute to prevent pre-ignition etc. But one of the problems IMHO is that it is a misnomer to call it LL when in fact it has a lot more TEL than the leaded fuel we used to be able to buy at the pumps. I believe the LL is just to try and appease the green lobby.....
Theoretically the woodruff key should not take any load from the engine at all, it only locates the flywheel correctly for timing purposes.
I would be investigating the torque you are using to retain the flywheel onto the tapered fit.
Also worth checking the tapered fit itself and maybe lapping it to correct if the fit/surface is poor.
Hooray, for once a correct and sensible answer on here! Take note especially of the last sentence.
I suggest you check thread dia to see if it is 14 or 16mm then just do a search on evilbay for Honda petrol tap (loads on there) find the one that is right size etc see what model(s) it fits and buy a genuine Honda one rather than the chinese **** that proliferates on there! 🙂
If you want it to last, suggest you grease the tensioner pivot,dogbone bearings (inc ones in swinging arm)and the wheel bearings. Others have found the steering head bearings to be a bit lacking of grease as well. Hope this helps.
Or just go to a friendly / educated test station and save the hassel
I don't regard education as a hassle really. I agree with a certain N.Mandela who said "Education is the most powerful weapon which you can use to change the world."
