So I've seen lots of posts on performance and maxing speed. I'm curious, starting with a brand new china engine 48 or 66cc; what all can be done to make it last forever......well as long as possible? The reliability of these engines, from what I can tell, is scary at best.
The focus here then, is not more power or final speed, only reliability. I'm not an engine expert nor have I messed with these engines, however some reading online has given me ideas to start the ball rolling.
- First I assume do all the steps from the Pre-build checklist on this site here. http://www.motoredbikes.com/showthread.php?t=11986 (sorry for broken link)
- Second replace bearings in the engine, right?
have found from searching I guess, from what I've read that's figured out. SKF 6202-2RSH Roller bearings (4) and INA K10X14X13-TV or INA KBK10X14X13 or gilardoni 10x14x13 needle bearing for the top connecting rod (credit here http://motorbicycling.com/f13/66cc-engine-tear-down-setting-high-27007.html )
- Third, Port the intake and exhaust? I know everyone seems to do this for performance but would it also help reliability?
Like I said I don't know much here but I think maybe these few things will help? Anyone have any ideas?
