ladies...
really tight means really tight.
a torque wrench is useless on these little buggers.

Well after checking around my 3 other Gs1150 based engines(1150 heads) to make SURE the nuts where MAN tight,I used a Craftsman Torq wrench at 8.5 ft lb,I know to do it with an open end wrench or Z1 tool,but I was just checking things Bored waiting for parts and found this on my dragbike Engine only been down track 4 times,I quess this adjuster was ready to let loose also...This engine was built by a local PRO guy had different size nuts on the adjuster screwsBikebandit here I come.After finding this I am glad I have 1150 heads on all 3 of my bikes so Valve cover will easy to get to not 20 bolts like my old 1100.I must say this has me PARINOID.....

The Valve damage the screw caused,glad i have an almost fresh set from an 1150 parts bike years ago...Every exhaust valve except the one that the adjuster came lose on..lol and 2 intake....

GS's take 8mm wrenches or was there a mixture of 8mm and 9mm used.
i thought roller bearing GS's used 9mm.
i robbed some from an 83 750 years back and they was 8mm.
is GSXR's 8mm also?
i also use a box end wrench even if i have to modify it some with a grinder.
i wouldn't worry about 2 diff size nuts..just man tighten them and life will be good.
sometimes PRO's build the engines and have minimum wage grease monkeys do the small stuff.

to be honest a person with any type of performance parts should have a routine to go over things such as valve adjustments and such a couple times a month(drag racers or hard street riders).
this could save a lot of down time and dollars out the window.

Thanks for the reply,Yea i checked the valve clearance after the bike ran down the track 4 times it was fine never had to loosen anything,glad i decided to have a look,the adjuster was extended for the bigger G4 cams and did have 8mm and 9mm mitch match nuts,I know it dont mean much but when you pay $5000 for an engine the bolts should match,its not a junkyard dog after all..lol
