Sorry for all the noob questions but the pdf file manual I have doesn't show this stuff, how do u get the rod off of the crank to replace the rod bearing? It seems that the rod journal is pressed into the crank but at a second look I noticed that it doesn't look like there's enough room for the journal to come out passed the ends on the crank.

your better off just getting a new crank,unless your setup to balance and true it. you will end up with vibrations

I have about 5 of these paper weights. they work great as door stops too.

lol, well this brings me back to my other post about stroker crankshafts, can you SAFELY use a 3mm stroker crank with standard height big bore cylinder? on the hot rod crankshaft website when u look at stroker crankshafts it says it makes your factory engine a 470cc and when used with cylinder works big bore makes it 500cc's never mentions having to get a taller cylinder to compensate for the added stroke. i already have the big bore so if i have to get a crank assembly, i will get the stroker if safe???:D
