rockymountainatvmc.com and/or partzilla.com, along with your friendly local Yamaha dealer.

Rocky Mountain ATV and MC has been good to me. Should be a link on most pages.

Partzilla is another favorite of many... they've run hot and cold for me over the years... good service and then bad service.... the last time that they took forever and then shorted me on parts... even the packing list was marked "0" on the missing items... and didn't credit as promised was the last time I bought there.

RMATV prices are a little higher than Partzilla but on bigger ticket items when I've asked they always price match. And they have a much better free shipping policy... lower order amount and RMATV will ship twice for free... what they have in stock ships immediately... then they ship the rest when it all arrives. Partzilla waits until your whole order is ready which sometimes takes weeks.

I have also had really good luck with Rocky Mountain.

Thanks all!
I will give RMATV my money next time!

Thought this would be a good place to document the difference in the SD and SW crank seal for the magneto side thanks to folks on the thread




Hopefully I installed it correctly hahaha

Looks good!

Would it be ok to use oem Yamaha piston circlip on the wiseco piston I have?

They seem to be the same diameter, oem does look a tiny bit thicker

since it was bought up, how do you remove the darn wiseco clip??? That's what is on mine and it's a pain!

Get some needle nose pliers in there and pull it out. That’s how I got them out. Put your hand over the circlip because they will fly

I would order new Wiseco clips... not worth the risk. Should be pretty common, probably CW15 part number?
