You have to add both crank seals , and little end bearing to the list aswell

ended up costing me $750, customs ,seals and bearings
was not cheap in the end but its easy

and better than getting a taiwanese one for the same base cost

Lots of good info here...

Sticking to a 10,000 redline, OEM Yamaha parts are best & should easily last your season. (Ours lasted through the 24-hours of Nelson Ledges more than once.) Lightening the stock rotor helps but if you are concerned about the crank spreading, a small tack weld on the stator-side crankpin will hold it. No need to weld all the way around, as it is just more to grind off when you rebuild it next.

To answer your original question, if you have the time, skills & tools to avoid paying a shop to do it, then by all means tackle it yourself.

I note that the Hot Rods crank I have uses main bearings without dowel pins. I will be switching the outer mains for genuine Yamaha...

Interesting. Any reason for this? Run some loctite on the outside and should be fine?

Hot Rods?
Just more Thai Crappo Quality Reproduction IMO. Certainly Not cheap enough to take the Risk.

Read it. I never mentioned their converter, i said to use another. I was saying that an OEM banshee crank is US$400-450 and you can work that out in whatever currency you like yourself. Personally, I always work in the sites original currency and then convert myself, why would you trust a 3rd party youve not used before??? Even big players like ebay and paypal just guess until the transaction goes through.

So, as I was saying... the banshee crank was $408 at Ron Ayres last time I checked. work it into your own currency using a converter you trust once youve added the post, job done... No meats here!
Lmao, never mind that Jon I guess I was kind of toasted when I wrote that.I´ve been working too much I guess. I don´t know where did that come from either.
What happened to me was that after using their currency conv. I came to a figure that was outstanding for a crank so I went ahead only to find out after alls been said and done that I was better off had I bought it in Europe, and basically because I disregarded the little writing at the bottom of the page.
