Okay guys, First of all i recently traded a blown kx80 for a Brand New stroker, and a new set of Vforce3's. When installing the crank i used the old bearings that the motor came with. Alot of you guys told me that it could lead to a big catastrophic failure using these old 89' bearings after i beated them out from my stock crank. So i ordered som Hot rod bearings and seals. Now, i was recently reading a thread about Vito's 3mil Vs. Hot rods 4mil. I was reading that these cranks dont hold too much and alot of members were saying that they will pick the 4mil over the 3mil. Im not true'ing or welding the crank, im going to do trails and some Drag. I ride these blaster's pretty hard trying to keep up with the Dirtbikes And other Blaster's lol. Now would this crank hold the abuse for my riding type? Im ordering my pston some time this week or the next.Im going to use the spacer plate because my cylinder is on its second to last bore. But ill be running a cut head for more Compression. Thank You guys for reading! Any input or Advice would be really good.
