piston question

[ilmoakw]

Im rebuilding another 200S engine. My buddy was over last night and recomended enlarging the oil holes for the wrist pin to get more oil in there. Has anyone heard of or has done this?

I done that on Mopar 440 stroker engines, might not hurt on a trike.

i don't think it' sa good idea on atrike. here's why. if you push too much oil there, you'll end up robbing it from somewhere else as trikes don;t have much spare oil like a normal larger motor. Also you'll end up lowering the oil pressure and that coudl mean less oil getting to the bearings under ehavy accelerating and thta means engine failure possibility.

i woudl leave those alone, now if you want more, you can look at either getting a 200x piston for it, or getting a weisco larger piston high comp setup for it. you can get a weisco setup with top end gasket set for about $145 online. then it's about $60 for a bore and hone and your set. if you want more, then your looking at cam and springs, and cnc valve job w/porting. at that point a top end rebuild woudl be pushing the $500-$600 area including wesico piston setup.
