Ok gang, here's the deal. We have a lot of experienced people with R1s and drag racing on this forum. And we have a ton of information buried within threads. Sometimes the search engine can let users down, and not spit out exactly what they are looking for. And sometimes people just don't want to read through 5 pages of posts for the one little bit of information they are looking for. Having all the typical questions/answers along with basic information like yammy part numbers etc. in one spot would be tremendously useful I think.
Please reply on this thread with any input. Post up any question you think would be appropriate for a FAQ sticky. Even if you don't know the answer, post the question anyway, someone here probably knows the answer. I really think this will be a group effort, and just wanted to get things off the ground.
So I think there are "general" drag racing questions regarding launch techniques, bike setup, etc. And then there are model specific types of questions. I don't think we have to get so specific as to break it down into more sections. But if we find we have a ton of info we could break it down to chassis/tires/engine/etc. I have no preconceived ideas on what the results will look like, only that a bunch of common/useful information be easy to look through in one spot.
Once we have enough input from people on this thread, we can sift through and put together a legible FAQ that can be posted as a sticky by a moderator. Goobr, a moderator here, has already agreed to make a sticky for what we come up with (thnx mucha!).
Here is what I blurted out as a start to a FAQ in another thread. I didn't really put much thought into it, I just typed what came to mind. So come on gang, let's get this thing rolling...
general clutch questions:
Q) I own an '04/05/06 R1, and I think my clutch is fried. I only have X amount of passes on it, and X amount of miles. can the clutch really be gone?
A) Yes it is likely the clutch is toast if you've been making passes with moderate slipping through first gear.
Q) what is the best replacement clutch for drag racing?
A) stock yamaha parts hold up the best, and are also the cheapest. don't forget to replace the half plates with fulls. many times you can get away with just replacing the metals when they warp/glaze over.
Q) how many passes should I expect to get from a clutch?
A) depends on how hard you are riding the clutch. I've broken clutches with just 5 or 6 passes. I've also managed to get a couple dozen medium'ish launches out of a clutch. with a stock bike and 10k rpm launches, expect few passes. with an extended and geared bike expect to get more. with softer launches from say 4-6k rpm, expect to get more passes. etc. etc.
Q) what parts exactly need to be replaced when changing clutches
A) assuming all plates (fiber and metals) are being replaced:
<xyz> number of fibers - yammy part #
<xyz> number of metals - yammy part #
Q) how the frig do you get the clutch cover back on
A) try some wheel bearing grease, but mostly patience, experience.
Q) do I need to replace the clutch cover gasket as well?
A) not every time, as its a metal gasket. but typically I do every 3rd or 4th clutch
Q) will an oil line from tobefast help with clutch longevity
A) I'm not convinced it helps, but some swear by it. your mileage may vary.
Launching questions/techniques:
Q) what rpm should I launch at?
A) depends on a lot of variables
what year R1?
stock bike? extended? geared? lowered?
techniques on launching will also differ from person to person. some will hold throttle and ride clutch and slowly roll on throttle. some like to start from a lower rpm and quickly roll on throttle and let clutch out from the hole. etc..etc.
Q) should I do clutchless shifts?
A) yes
Q) does clutchless shifting hurt the transmission?
A) not if you're doing it right
Q) how do you properly do a clutchless shift?
A) blah blah blah
