I had a job that was never going to go well. Removing the blowing exhaust headers from my old 2007 CBF1000.
The bike has now done 122,000 miles and 16 winters with the original exhaust never being disturbed. I could see that 2 of the nuts were visibly eaten away by corrosion, but the rest looked ok. However I was expecting everything to be totally seized.
I cleaned them up as best as I could reach and treated them to a week of daily Plusgas soaking.
The nuts to the furthest left and right both moved, but they've lived their lives with the least spray from the front wheel. The rest of the nuts were solid.
The results so far? Out of the 8 I managed to get 4 to come out cleanly, although it was the studs that turned out. All the nuts are firmly welded to the studs with corrosion. 2 snapped studs and the 2 heavily corroded nuts just crumbled.
So, next step is to try to clear the remains of the 2 crumbled nuts from the studs so I can get the headers off. Then I'll waste time and effort trying to turn out the 4 stuck studs before I eventually lose patience, cut them off, drill them out and helicoil them.
I've got new(ish) headers with only 25k miles to fit. ____________________ 2016 CBF1000F - Commuter heaven | 1994 CBR600FR - Awaiting defibrillation |
