Actually, it sounds as if you have most of the mods done, so at this point, I would check your settings in your manual for the suspension, and start from there. MAYBE you need it revalved, but if you don't have it adjusted properly, that will do it too. I agree, a new bike would be awesome, but I am assuming if you COULD get a new bike, you would, so I won't state the obvious. With the mods, I bet your RM is on par powerwise, and set up the suspension, You will be FINE on the trails against the newer bikes. As for racing, I'm sure you would be fine in Lower amateur racing, assuming if you were serious about racing you wouldn't be asking about a 93 RM. All in all, have fun! The better, more comfortable the rider, the faster you will be. The answer is not always to buy a new bike, but if you want to race against the best of the best, then, you'd better equip yourself properly. Only YOU can answer that question.
