head nuts ? was created by pete greek1

the head nuts are rusty on the 76 900 I just bought, & want to replace just the 4 outside ones for now, & the copper gasckets, can this be done if I alternate front on one side, back on the other side, & visa versa, or will I have to worry about leaks, & have to replace them all & the head gascket...Pete

First time I've ever seen blue carbs!, like the paint otherwise. Oh yeah, should be good one at a time, recheck them after a heat cycle(when cold). Add a dab of oil to bottom of nut for cleaner torque reading( I know, iknow OCD)
Mine:
04 Honda rebel 250(wifes)
04 GSXR 750(bolt on galore)
98 CBR 600F3(filter, pipe, adjustable cam sprokets, dyno tune)
76 KZ900A (LTD gauge pods, crash bars, LTD(style)pipes, dyna coils and ignition,headwork and mild port cleanup by cavanaugh racing, K&N filter pods, heck I dunno.

Wireman,...if it starts leaking, I"ll have Leon give me directions over the phone, it should take me about 10 minutes, my tools are a pipe wrench & a screwdriver, as far as the blue carbs, after I put the 29 smoothies on it, I"m going to sell them to RonKZ 650 !!!! :laugh: :woohoo: :woohoo:

Make CERTAIN you torque all the head nuts and check them again after you heat cycle the motor one time. That should be on on a stone cold motor.

It's the failure to retorque the head after that first heat cycle that causes leaks.

BTW...did you buy that bike of Old Kawman? :side:
