First I will start with what I have now and what I use my busa for. I have a 2007 Busa with the full B2 Boz Bros exhust, smal airbox mod, a BMC race filter and a PCIIIusb. I use my bike for everyday riding, commuting, twisties as much as possible, the occasional race here and there on the street and I hope to go to the track this year once but have never been to the track yet. I keep telling myself I will go each year but never find the time to go. My goal here is to build a motor that will last with very little problems. I want to do this build right the first time.
Right now my tranny is at APE getting undercut ( Just talked to Jay yesterday and it looks like it is going to be another 2 weeks  but thats ok since its supposed to snow here today so cant ride anyways)
Next week I plan on sending out my block and cams to Jay to get the 1397 block with the JE pistons and some webcams plus I will get the high flow oil pump. I will be also using engine ice, duel fans hooked up to a switch and have not decided yet but I will be running either one high amp or duel batteries as well (hoping to get away with just one battery).
I am debating on the lift to get on the webcams. Originally I was going to get the .395"/.378" lift cams that would require the titanium retainers and valve springs. But now I am debating after talking to Jay about getting the shorter lift of .378"/.330" since it might keep the power band lower. The webcams will be coming with the adjustable sprockets as well. Also one other thing that should be mentioned is I will be getting a port and polish job on the head too.
My question to you is:
What lift is better for the street and occasionally blow your friends away?
What would the difference be in low down power?
If anyone here has the same setup what kind of #'s do you see?
One question about head gasket. Should I get the standard thickness or the .018" head gasket?
Also is there anything else that you suggest?
Thank You for all you help!
I just have to throw out a pic or two..... |
First question, what climate do you live at?
Second why are you undercutting the tranny, did you have a problem?
Third, on your valve job, is he pushing the guides down or leaving them stock height?
As for the head gasket, run standard thickness,
Do you know witch 1397 pistons you are getting, are they 12.8 to 1 or the 13.1's?
Cams are a funny topic, here, im building DnGrumpy's 1441 wright now, and have researched what will drop in. And i have come up with various answers to the question.
By far a 378, is a drop in!
A 395, some say it will drop in,, and some say no!
Im in the process of measuring to see if it will drop in, or not! The ti keeper's are a waste of money if your machinist is moving the guides!
Also the oems keeper's last longer!
