No,I run one battery with 325 cranking amps.
dang that is as large as some car batteries...reserve capacity must go pretty quick huh?
just some dropins and cams wont get you there. Thats probably only a 20hp add there.

Not really,it was made by Yuasa. The new model has 310 cranking amps. YTX20HL-BS-PW

i am going to check that out.....i also thought of wiring a second battery to the fan, so i could run the fan off a toggle switch and cool it. this battery would probably solve my problems.
do not mistake cranking amps with reserve capacity or to calculate steady draw.. you are STILL limited to what your charging system can cover.. 300W I think is stock? GixerHP had 400W stators?
That big cranking number is most important when "starting" the bike, after that? means nothing... many car batteries may only have 300-400 CCA but they have reserve capacities that may be very long.. look at the battery label, it has some fun data..

I would like to upgrade my charging system just out of GP... do you know how much the stator was?I know,my stator is not stock

I had it rewound,There is a company here in Orlando that does it. They rework Altenators for emergency vehicles. I beleive the Bad economy made then close shop,I will check. It was $150.00 to have my Busa's Stator and Voltage Regulator reworked.

well if i were to build a motor for boost (nothing extravagant im on the street most of the time anyways) what would i need? would there be anything else i should do to it while the motor is apart for a few more hp? im lookin for reliable power the bikes already have enough for the street lol but a lil more wouldnt hurt.
very cool...
you need to decide what the end product will be.... PERIOD... build accordingly.. I can not even count the number of hot rods i have built over the years where they started too cheap on the build for what they ended up with.. you then get to spend the money again and then some... Do it right the first time...
Contact someone like Greg at HPC ... you will save hundreds if not thousands by using his knowledge... Guys like him have very specific experience with specific motors and know what the limits are.. (this costs lots of guys lots of $$$ to find out)..
Listen, and spend accordingly.. you will be far better off to budget $5000 now than $3000 now and then $5000 again later when things go south.. I have seen this happen way too many times with far larger amounts of money..

when building a bike....it is best to :
1. set your goals....for example 250hp or 9.20 1/4 mile
2. look at your finances, and come up with a budget. be realistic
3. do some research, and come up with a plan
stick to the plan....

i dont really have a specific hp goal but i would like to have a turbo bike. more power is great but i dont want it at the expense of reliability even though i have a 600 for daily driving now so im not putting all the miles on my busa.
if you do not know the HP you want then they are right... what is the budget?
Who cares about the mi. on the busa. If you putting alot of mi. on a bike than your gonna want them on the busa cause it's WAY more comfortable.
Sounds to me like you should go with a stage 1 turbo (around 240hp) and I think you can get the kit for about 3500

o yea i was thinkin about a 1000 or busa.....hands down the busa won after ive been riding the 600. dont get me wrong i like the 600 but its stayin stock it just reminded me the busa is a mans bike 
as far as a price range i dont really have one just gotta save x amount of money. at least it gives me plenty of time to read up on things and ask questions on this forum

First things first, a motor is a electrical device used to make power and a engine uses fuel and air and a spark to make power. I have built several high performance engines over the years but I have never built a "motorcycle engine"---no pun intended. However, both automotive and motorcycle engines respond basically the same with performance modifications. If you can build a car engine you can build a motorcycle engine. The Hayabusa engine has had years and years of aftermarket and private high performance development work done to it so it is a matter of what your performance parameters are.
had to laugh... Engine/Motor.. we went through this lecture in school...
I think you are pretty much correct, a power plant is a power plant... However there is a certain amount of "overbuild" on any assy ever built.. I think bikes have a lesser amount of this "overbuilt" technology.. This might make them a bit more sensitive to errors in tuning and durability (heat again)
I like building the bike engines because they are smaller and easier to work with.. If you have ever done a transaxle, the transmission is also a piece of cake.. it is a matter of learning a few of the ins and outs of setting up clearances etc... I think I like the brute power of a 500cid nitro burning fuel motor at 8000hp but the thing is a sledge hammer in design compared to a 1100CC bike engine with transmission that is more built like a swiss watch.. apples and oranges but they both make juice
Both are very interesting in their own right.. and if you can work on one, you can work on the other.. (I would add you can probably learn computers pretty quick if you can do engines)
