Roadracing World magazine did an in depth article on that weaving to heat tires up urban legend a few years ago. Basically they used temp sensors on the tires to see how much heat was generated by weaving as opposed to just going straight & accelerating normally & also by accelerating & decelerating. The weaving did just as much heat build up as just accelerating. No more at all. People see cars doing this weaving stuff on race tracks so they just assume that doing it on a motorcycle does the same thing. Wrong. Accelerating & decelerating helps build up heat more than just plain accelerating & combined with going through turns normally that is the best method to get those tires up to temperature.
Jake is right about getting a new set of tires mounted on the track & being able to just warm them up normally & then going up to your usual speed. It is amazing how much B.S. there is out there regarding tires & what you can & can't do with them. At a WERA race last season a rider came up to the hot pit entrance & demanded to go out & do a warm up lap with the bikes I just let out on the race track so he could scuff his tires before his upcoming race.
No, the 3 minute board was just going up & he was not taking his GSXR1000 out on a track with a bunch of 250cc 2-strokes who were already on course & about halfway through completing their warm up lap & then be gridded up for their race. The guy starts yelling at me calling me a friggin' stupid a-hole that needs to learn about racing & get a life & get out of his way.
No. The guy tells me if he crashes on his new tires it will be my fault & I am making things dangerous out on the racetrack unnecessarily.
No (yeah right buddy). He then ends up telling me I will pay the damages to his bike when he crashes during his race & he will make sure he collects it. As he says this he rolls his bike up between my outstretched legs in an effort to try to intimidate me.
No (you have got to be kidding me - like to see you try pulling that one off!).
At this point I make the radio call for back up as we need to get this friggin' moron off the hot pit lane so I can hop over the hot pit wall & help grid up riders. Given the jerks refusal to accept a firm "No" several times I am pretty damn sure the guy is going to try to sneak out on the track if I leave the hot pit entrance unguarded. That means all those riders who just got their tires warm will have to wait til' we chase the joker off the track & by that time their tires will be cooled off. That's just not going to happen. Unbelievable. After the race day I talked to the tire vendor who sold the dork the tires (yeah, we keep notes on racers that act like morons) & the vendor claimed the rider was arguing with him as well telling him what he needs to do with his tires despite several reassurances by the tire manufacturer's track side race support professional telling him he was wrong & not to worry.
OMFG.
