Hello,

I have a question regarding the front bearings of the new Novarossi Flash and 353 engines. The Flash has a front bearing with metal seal #17010 and the 353 a front bearing with rubber seal! Look at the explosion views on the Novarossi home page. On the picture both motors have a bearing with metal seal?

And second question … a bearing with metal seal has a non contact seal that prevents only the bust to enter the bearing. In other words the sealing is achieved by the form of the metal cover with contact only on one bearing ring, the other side the air can enter freely! So basically you have an air leek on the bearing? Can anyone answer?

Cheers
