I decided to open a new topic to entertainment you with my 2nd edition engine build and
raise some useful discussion up about a Revolution pushed to it's limit in street use.
My target is 250rwhp@7500rpm 185 ft-lbs@5000rpm, but especially I'm trying to improve reliability, which has been the problem. I'm fustrated to open the engine every 3000km.
So, here we go....
CP Pistons are the old ones, driven 6000km. There are couple of scratches in a skirt because of flying bearing pieces in the engine. They are measured and polished to prevent carbon building to the top. Compression ratio is a mandatory in my case.
Has somebody seen somewhere forged pistons for 4.25" (12:1, 1/4" stroker offset pin)?
New piston rings and at this time end plays are adjusted smaller than previously.
1st 0.60mm
2nd 0.70mm
oil ring 0.35mm
Old K1 rods, new bolts. There are marks of flattened and spread pin bushings under pressure. Pin clearances are still okay, but too narrow or soft pin bushings will be a problem in the future. Better pushing material will be needed some day.
Wiseco cylinder liners are used ones. They are measured and re-honed to RA12 recarding CP's instruction for Ductile moly rings.
Falicon 3/8" stroker full circle crank. As I know there are two types of Falicon full circle ctranks in the market.
The other one is with an open rod pin and an other one with blugged rod pin, like mine. How are oil drillings when the rod pin is nod blugged. Does somebody know what is a backround for changes?
