I've got a crank I would like to get rebuilt and I'm just wondering what my options are, I've got a quote from Crank Works for 620, just wondering if there are better/cheaper options, Ive heard Art from Jet Works rebuilds them but I haven't heard back from him yet

620... 848 for a new oem. i would pay that difference. my point is crank works is taking advantage of people because there are not many who do this line of work. couldnt anyone with the right tools rebuild them for less than half of 620...

Art doesn't rebuild those himself. He sends it to Crankworks. (Unless something has changed)
I had mine done and am very happy with the results. $520 to do that, 2 years ago.

Pat from Patch motor works does all our cranks, he's swamped this time of you but worth it MOTO360, He just finished up my new 846 DASA crank. Either that Jetmaniac or Fast Elements for an SBT'er.

Art (Jetworks/Blackjack) has my 5mm+ crank right now. To the best of my knowledge he's the one rebuilding it. I dont know what hes charging me to do it though, still havent gotten the bill for my new motor:icon16:

For under 400.00 you can get a quality rebuilt from Competitive crankshafts.I have built a couple engines with them and they seem to be holding up great.Stay away from hot rod cranks the rear brg can come apart.

Munki63, what does your crank need? Does it need 2 new rods and all the bearings? Or is there some parts on your crank that are still good?

Don't know got is used, I'm not a crank expert but if I spend the $$ on a new X-metal or Jet Works motor I'll be putting a newly assembled crank in, not uses... Advice from Matt E
 
If your 5mm stroker crank has the customary stock lenght rods, I would only use Yam rods (Kawi rods if longer) That and the bearings can be had for about $500 + 100 labor. If someone can rebuild it for less, they may not use quality parts. The expensive front bearing can be usually be reused if no evidence of rust is noted. I would not try to rebuild one myself, to difficult to phase the center section.

I forgot!
getting it trued and welded is a very nice option too. I had a place in quebec rebuild a oem crank with all oem parts and it was not cheap, slightly less than a new oem but they trued and welded it. It was the smoothest running motor i had. i can't remember the name of the company. i will look.
 
I talked to Art at Jetworks yesterday, he uses Japan Nachi bearings except for the expensive front bearing (oem 125.00) he uses a Korean bearing that he's had no problems with...he will install for extra, an oem front bearing if you want...

There are a lot of reputable shops, even locally. It all depends what parts you use and how much of a discount they or you get. I use Pat bacuase he showed me how he does them, then he showed me how he phases and trues each one. There is a tolerance on truing, and he does them better than the book. I had a stocker that was WAY off from yamaha. FYI all cranks are trued, by all shops, they have to be. Not all cranks are welded. If they are going to be shipped via UPS or something, they should be. I appreciate all that he has done for us, and he lets each of us select the parts we want for the build. I will only use OEM beaaings, the one he is finsihing for us today is not. Thats what matters to me, could I get that service any place else? Maybe but not over the phone.

Compettive crankshafts does the same thing. O.E. brgs rear and 2 center single row with a aftermarket double row front.He can rebuild yours or when supplies are available all new parts.20 years in the buisness cranks for pwc,atv's and motorcycles.I paid 350.00 for one I picked up yesterday.Great cranks , fair price and good communication
