locogato11283 Posted December 9, 2018 Report Share Posted December 9, 2018 JFC. You might get parts for a 521 motor build for $3700, but not a turn key deal. A 521 isn't something you can just slap together anyway. Quote Link to comment Share on other sites More sharing options...

specialblend07 Posted December 11, 2018 Report Share Posted December 11, 2018 LOL. You'll be into suspension for almost $4,000, then $6-7K for a COMPLETE running motor. Quote Link to comment Share on other sites More sharing options...
ZillaFreak Posted December 11, 2018 Report Share Posted December 11, 2018 Did the 3700 include trench of the cases for the 10mil crank? Did it include bore of the top case for the 72mm bore? Quote Link to comment Share on other sites More sharing options...

Reason I asked about trenching and boring is because it is actually needed for the top end and crank to even work. You can still run stock carbs, trans, and exhaust and it will "work" just not correctly. Quote Link to comment Share on other sites More sharing options...
specialblend07 Posted December 11, 2018 Report Share Posted December 11, 2018 Good luck with that kit! You'd be better off with a ported stock cylinder at that point. Quote Link to comment Share on other sites More sharing options...
ZillaFreak Posted December 11, 2018 Report Share Posted December 11, 2018 He is trying to MX this 521, so ya stock cylinders would have been cheaper, faster, and better for MX. I for see this happening but way worse. Quote Link to comment Share on other sites More sharing options...
