My 954's block cracked on the dyno today!
I took the bike to get custom tuned today after putting on the full Hindle. The good news was that it went from a baseline of 137 hp to 145 hp and 72 ft-lbs after the tuning with a nice 13.2 AFR and pretty flat hp and torque curves. During the last pulls, though, the bike started leaking some coolant although temps had been in the low 200s. We noticed that the leak was coming from the front left of the block a few cms below the head, along what appeared to be a casting line. It seems that the block outside of one of the water jackets cracked across the front of the block. The bike was allowed to cool down between each set of a few passes.
Has anyone heard of such a thing? This seems like really bad luck. I'm thinking that this area may be able to be welded. Tho other options are going with a used motor or getting a new Honda case, but that's probably not worth the cost of parts and labor.
Any thoughts would be appreciated. I was so close to that 9 second quarter mile until this happened. Did I mention that this really sucks ass?
