Reply To: Yamaha kt 100 engine life vs power

Yes it does, compression may be good, in fact with the modern “Gold” ring compression rarely suffers.

But piston wear will create extra slap which is bad for top end performance not to mention the chance of skirt breakage. Main bearings also lose power after X number of hours.
