horsinaround930 if you dont mind me asking...... how much do you weigh?
If I was looking to build a consistent 8 sec bike on motor I would definately do what bisquit61 suggested
1397...cams....headwork....gears...good exhaust...good tune....upper or if your a real good rider mid eights. totatlly reliable for street or strip.
minus the clutch mod...I would spend the extra coin and get a Rock Solid Clutch setup soo you can run it in hand slider at the track and regular clutch on the street. You get someone like Rearick Racing to setup th clutch for you and you will be set. Another thought is if you gonna go go to a 1397cc drop the extra grand and 1441cc it.
. Make about 200-210 or a little more depending on your builder or tuner.:
This is a very true statement!! If you want it done right then get with someone who really knows the busa!! My tuner has been racing busas since 99 when they came out!! He has spent a fortune over the years running different cams,degreeing them different ways,compression changes,head worksuspension work,clutch setups, etc,etc,etc!!! If you are in the central texas area holla at me. Ill get you intouch with him. I can tell you I have seen his cam-only setups make 193-195whp on motor 255-265whp on 60 shot. They just dynoed a stock headed 1397cc he did years ago. Owner finally got it tuned and it made 219whp/123wtq. With it geared for nitrous it went 8.8@152 on motor. He is a good guy and lives at the track so he is always down for helping out with things.
From what I have seen around here weight plays a big roll in how fast the bike is..... but also the air,humidity,sea level blah blah blah all changes what bike do in different locations. ie requiring more power,suspension etc to reach your goal!!
You will see that some things work for some while it doesnt for others. As soon as I stretched my bike the stock shock went to crap!! It would squat so hard that even with a tiger tail it rubbed. I dropped the coin for the penske shock so I would not have to **** with buying stock shock after stock shock {shimming,springing and revalving} a stock shock for it to fail. Mind you Im 230lbs unsuited!!
Its like they told me when I came on here talking about fast plans!!! Welcome to the forum and get ready to spent some money!!!! I dont want you to misunderstand what Im saying!! You dont have to buy the best of everything to get the job done!! I have seen bare bones stuff move the beep beep OUT!!
A suggestion is to go to the track near you and see what the locals are running. Maybe talk to them alittle and see of they will give you a idea of what they have done and what they run so you have a idea of what it will take you to acheive your goal!! Just dont watch what a 140lb rider does if your 230lb because you will never reach that with the same mods!! Little skinny bastards LOL jk!!!
Aside from that................... man have fun!!! I started racing my 03 Busa may of these year and just cant get enough of it!! I too have 8 sec plans. I kinda went the reverse route by doing a fuel system,penske shock and RSM clutch. But after making some passes on my bike I knew I would be addicted and looking to go really fast. So they were things I needed.
