Question for the hive mind…just offered up my Malossi 210 piston to the crank in the motor I'm building for for my Rally. When I put wrist pin in with the clips there's a gap between the pin and the wire clips. Bad? Don't worry about it? The wrist pin is from an older Malossi piston I had as I can't find the one that came with the kit.

Just want to make sure I'm good to go before I button this thing up.

Cheers!
Nate

It's normal.

Newer 2014 kits are the same.

I usually make sure the c clip is installed properly and the gap faces the top or bottom of the piston.

If you can get a chance, a good upgrade to the older kits, is to widen the exhaust port.

If I remember correctly, something like 60mm (I need to find my old notes).

And also enlarge the piston windows.

It's copying a German workshop technique. I tried it on a stock 210 setup, and it just ran faster.
