Re: engine refresh
After pulling the pistons out I can see that the cylinder walls are badly scored and the plating is worn through.
I'm counting the cost/ benefit of boring and replating, 76mm high comp. pistons, gaskets and bearings, & valve job. vs. just finding a good used engine and getting the bike back on the road faster/cheaper.
I know I would really enjoy a 980cc with 13.5:1 compression, but I would probably want bigger cams, ported head, maybe bigger valves, then it would need bigger throttle bodies and then of course it would require a lot of dyno tune time and a custom file... It's fun building horsepower but I have been down this road before with cars and I know it's a money pit and I might end up working on it more than riding it.
