split 3 hawk motors n all have bad crank case bearings,one spun idling,one showing copper,other badly worn no copper.rod bearing condition varies,1 fair,2 getting bad.one 17,000miles,from wrecked bike.one w/from25,000-30,000mileswheelied/wrecked bike.one on bike i bought with 38,000miles.want to know if others here found similar bearing conditions in their motors.i figure lack of oil,low level and or wheelies,since hawks use little oil regulary,or lack of oil/wreck/running,since no tip over switch is fitted to any.since those big pistions/crank generate a lots of forces is this a problem thats gona happen even with u guys having brand new bikes babied with fresh oil changes n regular maintainence or motor design flaw for all hawks n rebuilds necessary by 30-40,000miles,like,dare say,harleys-or what.fill-in the blanks gentilemen.inline fours i've been(many)have no such issues with widely varying mileage n maintainence.i need to know the life span of these motors as it may alter my long term use of them.waiting on me to throw money at them.senior members?ay n all info very greatly appreciated.chris in ga.

I've parted three superhawk motors now.

All three were just damaged heads in valve crashes

No bad crank bearing wear noticed.

From what I've seen it's not an often reported problem and there guy's on here with 60-90000 miles. Typically not a honda weakness!

ok.bearings will be replaced in this last go-around n see what happens.swapping heads round with others i have as the cam bearings also showing wear,with a cam having a black line from heat/friction around bearing surface 1/16"wide.good to have spares.cylinders of this motor are great,runs stronger than any motor thus far.why i'm so disappointed.(so thats what a good running hawk feels like).synthetic oil will be used.my daily driver ninja 250 was monstertrucked-totaled by my boss,who caused other issues.no d.d,no job now,he finally turned it in on ins.so waitn on hawk parts.bought this motor to run till insurance came thru.cant work till fixed;why i'm learylong ter. i ride a bike year round,rain,cold,whatever.got to be reliable.thanks for the info guys.feel little better now.went to the 'gap"in a car this weekend,i was a roadblock,but had fun talking bout bikes,hanging out,etc.next time i'll be on it.anyone else have anything to add let me know
