How about a 999/1038 kitted engine, sell you 749/924 kitted engine. Swap! Some owner would love to have that 924 motor-unless your attached to it...
I think we have special relationship. I still remember that moment when I was in 6th gear WOT and I felt this small hickup from the engine. That was the end for the cylinders and pistons. Also emptied my wallet quite effectively
I'm not sure how much money the bike is worth because ppl are always worried about tuned engines since they don't know it's past. So I'm quite skeptical about selling it for any reasonable price. Therefore the bike's a keeper and if the engine would go some day then it's 1198R engine in it for sure. So many other goodies in the bike that need to be used
