What's a good set of race heads for a 98 yzf r1
Not entirely sure of your question. Are you meaning the cylinder heads? You can do some things to the heads, porting, polishing, shaving etc. to increase performance and efficiency. However, you don't generally replace the heads themselves with anything other than what was designed for that particular block. If you are looking for ways to increase the performance of your R1 there are many things that offer more bang for the buck. First would be some light weight wheels, magnesium wheels will reduce overall weight and increase acceleration etc. Cams, power commander ECU, after market exhaust (drops overall weight while generally increasing HP), SS brake lines, Galfer-like pads, racing battery (or none at all, less weight) racing bodywork, K&N air filters, the list goes on and on. Are you going to be racing this bike full time or just track days? There is a lot to be said for reliability. Unless you've been racing for several years, ie lots of experience all ready, there are a ton of things to learn as a rider to going faster than just more hp on the bike. There are racing schools available that can make you a much faster rider on the same bike. If you have unlimited funds for the racing effort than consider buying a Graves built superbike motor and just bolt it in. If you are on a budget, consider losing body weight (approximately every 7 pounds = 1 HP), reducing weight of the bike (aftermarket wheels, exhaust, rotors, bodywork, etc. etc.). Hope this helps.
