Lets try to get back on track and help this fella out. I mean no disrespect Nbomar but is it possible that the guys beating you have more experience in racing than you do? Drag racing is tough on machine and body and there is no getting around the repairs that will come at a quicker pace. There are no free rides, but as we have read from guys on this post it can be exilerating to get these big machines up to speed. To some it's very important and to others it's not and they will recommend that they are not built for speed or they may have another bike for such activities, we all have choices. It boils down to two things the machine and the rider. We know this forum is loaded with experience & knowledgable builders & racers. If it's important enough to you I would be practicing on my own and figure out the power band vs when to shift and work on your reflexes. You may be able to get faster without spending another dime. When I find myself in a situation that calls for my childish side to come out, I drop the clutch and never touch it again until it's over & I'm slowing down. I'm not recomending that you power shift but it has helped me even the odds on more than one occasion. I have been told by some knowledgable folks that it can cut at least one full second on a quarter mile run, I have no way of proving or disproving that statement. I guess if you figure on the amount of distance you would cover while counting the full second like "one one thousand" while doing well over 100mph that is a considerable amount of distance from clutchless shifting. Some of these guys have some impressive skills in racing & their machines, some are desighned for straight line runs and others are for superior handling. So it again points to machine and man, some excess cash is always good to have but then isn't it always that way. Try to get to a point so you have maximised your bike and experience so you are positive that you know that this is as fast as your combination is capable of going. At some point you will have to learn to be content with what you have unless you have an endless supply of cash, but you are still at the right place to get the information needed on where & how to spend it.
You may want to consider switching bikes with some of the people that you ride against if you feel comfortable with that just to see what happens, be carefull when driving different bikes as everything changes. Be safe and don't put yourself or anybody else in harm's way.
Good Luck & keep us posted on your progress
