I was wondering if anyone can help?I have a Sirion rally 2 and after two blow ups I would like to get the crankshaft re ground and use the .25 undersize bearings.i have the con-rod bearings sorted,but am struggling to get the part number for the main bearings.I ordered both sets of bearings at the same time.the con-rod bearings were fine but the mains have no tangs and the upper bearings have two oil holes not one.the part # for the wrong bearings are 11704-B1021-.I am currently throwing emails back and forward to the distributors,just wondering if anyone else had these problems?I did however manage to get an engine manual,which is nice!

somehow put this in 4x4 questions might get more looks here!
