+1, this is a very nice engine, the crank is not lightened but the rest of the work inside is super clean and a good value, i did a crank out of one of these for a customer and they are smokin, good linier feel and nice top end
You will be happy with the B3, very responsive on bottom and decent top for a 3 port, take good care of it and it should last a good while, not to alarm you but keep a close eye on the bearings, there has been issues with werks bearings in the past, other than that you should be good to go. Good luck
