Default os speed question

i just sent my piston/sleeve out to get pinched. i am also wanting to replace the bearings in the case. should i wait until after i break in the pinched p/s to replace the bearings, do it before, or does it really matter either way?

Replace the bearings now before the break in, that way they can seat with the new piston and sleeve. Thats the best way in my opinion.

I would recommend the same. That way anything thats lurking in the old bearings doesn't ruin your fresh pinch.

BTW how many gallons did you get out of your speed before you had it pinched?

maybe 3 gallons on a new piston and sleeve. i let e friend use it and i think he got it too hot. thats what you get for letting friends use your stuff right lol. also when i got it back there was a little bit of really fine bust on the inside of the restrictor so it way have gotten some dust in there too. not sure if he was using oil on his airfilter. i hoping this pinch will do the trick so i dont have to buy a new p/s. seeing the dust is also my reason for wanting to change the bearings

First of all I would never let a freind, cousin or uncle or brother drive my 500 dollar engine.

Second of all I have a speed with 11 gallons and still kickin strong.

YOU HAVE TO MAKE SURE TO LEAVE THE PISTON DBC, EVERYTIME. THEN YOU WILL BE FINE

I just hit the 3 gallon mark and its running better than ever feels like it has really come alive. I have got it hot once too around 280. Man I love this engine.
