For reference purposes this spring minus custom gap measures big enough ID to go over the sleeves, x 5/16" (8mm), x far as I can tell, 1,13/16 - 1,7/8" in length....
Plunger cush components look same as swingarm ones but in fact slightly physically different.
Update on previous post, figuring may as well keep the theme together.
Even though I asked for measurements when I ordered by phone, the replacement spring is vastly different to the original and measures,:-
0.303 wire
, ID 1.752", Long/high, 1.704"
~7.7mm wire, " ID-43.3, long/high 44.5
(similar to a10gf, but slightly different but seems to work ok)
I feel is not long enough, and a sloppy fit diametrically (3.5mm),and apart from not seating well on the landings, could affect crank balance to a small degree.
What I meant with the measurements from previous post, was what I think the spring should in my opinion ideally be closer to, as below;
( wire- 5/16" ID-1.625 x 1,7/8" long,
in metric-
( wire- 8mm, ID- 41.5+mm, Length 47.5 mm.)
Reason I needed a replacement was I had a noise at kickover, that I knew was cush related, but was running fine, so wasn't too concerned till the gear changes were a bit crunchy, so figured the springs needed adjustment- again...... good thing I checked.
Hope that's of help to anyone, cheers
