Title: Help confirming Piston Identity
Post by: r1_pete on February 08, 2014, 03:04:18 PM

I finally got round to stripping the bitsa engine, I'm pretty sure the whole top end is F2 - Head Barrels and Pistons, I'd just like some help confirming these are F2 pistons, I did expect a higher dome...

Hi Pete, turn piston upside down and the model code is stamped on it, I think 392( f1) or 410 (f2) 405 (k7)

Bottom picture L/H piston, if you enlarge it you can see 410 on the relieved area arround the gudgeon pin---so its an F2
