Diaphragms and needle...damn hole!!

[anteva2]

Hello everyone. I recently had to replace the main diaphragms on the carburettors. I know the procedure and the order of assembly. The thing is that when it came to assembling the needle, the support piece, the one with a small spout that has to be matched with a tiny hole in the base of the piston, it was IMPOSSIBLE for me to know for sure if the spout was or was not inside the damn tiny hole.

I have practically assembled the needles without caring if the "spout" matched its hole. The thing is that the bike is impeccable in terms of power, it needed a change. I don't know if I should be worried, what I do know is that at the moment the bike is going great, much better than before.

If it runs ok, and you think it's placed right, leave it.

I assure you that it is very unlikely that they have coincided. Another possibility is that the base, with the movement, rotates and snaps into place, although I do not believe this either due to the pressure exerted by the spring. The best of all is that it works and works very well. I am not going to take it apart again.

Assemble it loose, spin it, let the point find the hole, tighten er up.

Assemble it loose, spin it, let the point find the hole, tighten er up.

Especially when I was changing a lot of needles and tuning, that's what I would do. Spin it in place, and after it fell into place, then tighten everything down.
