At the end of last year, I bought an '07 mobius lsv. I just got done with the break-in period and gave it the juice. I am only able to get about 38 mph out of it. Don't get me wrong, I didn't anticipate rocketing down the river but I thought I should at least get 43 or 44 mph or was I wrong. My concern is that when I slalom, I may not have enough speed. Let me know what you can get out of yours.
