When installing the pistons, does the big notch go to the intake or exhaust side? I had a timing issue and turned the pistons 180 because they were hitting the exhaust valves. Now that the timing issue is fixed I'm worried the pistons are backwards.
Thanks, Jodie

The larger valve "pocket' is the intake, the smaller one should be under the (smaller)exhaust valve.....

I got it all together, correctly and surprise it runs. Nice Sprint BTW. I have a tx125 I ride around in the woods. I've been thinking about getting a 250 or 350 for my next project.
