good news i've been & checked for you & the S5 &S7II both share the same crankshaft so you would get the same power as a S7II
just incase you're interested the number is 01162-13B

I wasn't sure about the S5! I just thought I'd mention it to maybe save someone some grief. Sorry if I sounded negative!

The S7II is suppose to be a pretty hot engine! If you can convert yours to one I think you would be really happy with it! You might be able to use the rod you've already got if the bushing's still tight in it. Is your rod knife edged? If not it might have a different weight than the S7II rod and that would hurt you on engine balance. If it is knife edged and the same part number you could convert your engine over for just over $100. S7II for $100? No brainer! Worth looking in to!

The only reason I would still have doubts is because of the description listed for the S5 and S7II. If you go to the link below and read the descriptions you'll see what I'm talking about. Then again, it could be someone just got more colorful on the S7II so they could sell more of them. Don't know, I've never even seen an S5![&o] Hope it works out for ya!

yes the S5 also has the 1122C hardened conrod
the "C" meaning Competition!



the casings have a slightly different number though with the S7II having an "S" at the end of the number!this just denotes that the casing has been machined away a litt;e more around the rear bearing area

Good deal! I'd like to hear how one works out with these parts in it. I bet you could pick up used motors off of EBAY and put together some nice backups.

Just noticed your avatar doesn't have that bouncy thing going on anymore! I liked it when she jiggled!

thanks you guys for all ur help!!!! i will definately be purchasing a ws7II piston and liner for the s5 and i will let you all know what the results are.
