Lines: 49 Lane splitting - (In California anyway) is not specifically legal, it is "not illegal". It has to do with lane sharing, two motorcycles can share the same lane (two cars could if they were small enough), so can a car and a motorcycle. If the motorcycle is traveling at a speed much greater than the flow of traffic they may be guilty of unsafe driving though. It is not legal to use the shoulder or center divider, unless you are a CHP :^) Bluprinting - This is not necessarily building an engine to factory specs, just building it to "some" spec. What spec that is depends on the intended use. If it is stock class racing, then one bluprints to the most advantageous factory spec (as was stated). If it is just to get a great running street engine you blueprint it to most easily obtained constant. example: Combustion chamber volume (this is known as cc'ing a head) For stock class racing - The factory spec states a chamber volume of 65 cc's. Step one, find a set of cylinder heads with all chambers smaller than 65 cc's. Step two, enlarge each chamber till it's volume is exactly 65 cc's. For a blueprinted street engine - Step one, take the set of cylinder heads that you have and measure all the chambers, noting what the largest chamber is (this will usually be greater than the factory spec, say 68 cc's). Step two, enlarge each chamber till it's volume is that of the largest one measured (68 cc's). This is a subtle difference, but it is much cheaper to just blueprint an engine than it is to blueprint it to "stock" specs. I don't want to nit pick, but I have blueprinted a lot of engines, some of them for stock class racing, and there is a world of difference (try spending an entire weekend at an auto dealer weighing pistons with a triple beam balance, searching for eight that are exactly the same weight). -Pete- /<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>\ ^ ^ v Pete Bellas "When it is not necessary to make a decision, v ^ Citicorp TTI it is necessary to not make a decision." ^ v Santa Monica, CA Lord Faukland v ^ ^ v Path: ...!{randvax | trwrb | philabs | vortex}!ttidca!ttidcb!bellas v \<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>/ Brought to you by Super Global Mega Corp .com
