WOW!!! What do you guys do to cause damage to your engines? 2002 summit 700, rebuilt top end at 8500km due to power issues, top end was good, a little low on compression was all. Turned out to be the primary clutch spring housing was cracked, last time I take anything to a dealer! Oh, and did the top end myself, $260 from royal Distributers including full top end gasket kit. 09 m1000 5000km and still pulled the same as when I brought it home, 09 summit 800 4600km 135psi each cylinder and pulls really hard! Only sled they gave me engine trouble was that stupid RT1000, blew it up twice and sold it.
