Size of part no. 93210-27250
Hi guys! Can anybody help with the size (outer or inner diameter, thickness) of the heat resistant O-ring between mid- and end muffler?
It´s the Yamaha part no. 93210-27250.
Thx!

I´m thinking of the direction to install the 6 clutch damper of the rear wheel. Does it matter what direction the rounded corner be installed?
Please post a picture of the dampers you have.
No, it deos not matter if you are using the genuine Yamaha parts
I have a 1975 DT250B in need of a new piston. I was wondering if i can use a 1977/78 DT 250 piston. Wiseco offers a single piston that fits all of these models. So it got me thinking that a NOS yamaha piston could work too. Can anyone confirm?
I am looking for a 0.75 oversize so I would prefer NOS Yamaha. Wiseco only offers 0.50 and 1.00 oversize.
Yes, you can use a 77/78 piston in your 75 model.
But, If you'd rather have the correct one, let me know.
i can quote you a price for either piston.
I've lots of pistons for almost all of the Enduro models

I ordered inner diameter 28, thickness 2,5/3/3,5.... I tried 4 mm >>> too thick
