First what photo hosting sites are any good, I have photobucket but I'm not going to pay to post pics. The motor is going together, basics are CP Pistons, ti rods, billet crank and the head work by Vance and Hines. Frame, gen 1 with gen 2 everything else. Bodywork is Airtech Hayabusa B. Since Bridgestone 003's are no longer in production I went with the RS 10's. Next step I guess is put the bike together while I wait for the bodywork it should be ready in two to three weeks. Next I need to gather fuel lines, kill switch, fuel shut off, battery switch, sprockets and double check the rule book for anything else I will need to purchase.

Better than checking the rulebook for forgotten items -- is to get a copy of the Inspection sheet and go through what you're going to need to get through inspection.

Safety wires, tire age dates, full length metal chain guard, steering stops - stuff like that.

Have fun!  Remember that the inspectors want you to be able to race, too. cheers

1) Why ti rods and billet crank on a 1350 Busa class motor?

2) you do know that the Airtech "B" is designed to work with a Gen 1 and not a Gen 2?

Billet crank, Ti rods because 15:1 CR and they are less likely to spin a bearing at higher rpm's and I'm looking for a gen 1 cylinder block to go bigger at some point.

Spoke with Airtech when I made the order. You are correct about the gen 1, they told me the B body front will bolt up to the gen 2 stock fairing mounts and the rear bolts up to the gen 1 subframe but they have directions on the web site on how to modify the gen 2 subframe to fit

On the inspection sheet, I read through it but using it as a check sheet is a great idea thanks.

I find that it's good to have a reasonably intelligent, motorcycle-savvy but uninformed person inspect your bike while reading out loud from the rules & inspection sheet.
Their input  will be unbiased and ignorant of your concepts of how things should be. Helps to stop the tunnel-vision we all get and lets you see things from a different point of view.

How do titanium rods and a billet crank prevent bearing spinning? I see where the rods might be an advantage to reducing the reciprocating weight, however bearing spinning is due to lack of oil clearance/metal to metal contact. And that is remedied by having a high oil pressure and oil volume flow.
I am not saying don't buy those expensive parts but I just want to know how they prevent bearing spinning as you claim?

IIRC, the current APS/F 1350 record was running a Gen 2 crank and Gen 2 rods.  And the only thing that put that bike in "Fuel" was it wasn't running event gas.

Oil failure from heat, debris etc is probably the cause 98% of the time but when you have a motor that lives most of it's life over red line your chances of bearing fatigue increases. Knecum Performance is building the motor, we went went through all the different options and what the bike will be used for and this is the setup that was chosen. I have a 74 Z1 drag bike with a 15 year old Falicon crank and rods, it was money well spent

BTW HAPPY THANKSGIVING EVERYONE

OK, that's great that Knecum is building the engine. He is a Hayabusa expert. No doubt he will be doing some needed things to improve oil flow.

Ok I'm tired of trying to load photos, error massages and resizing pics. So here is a link to the photo album. I mounted the tires, the head is back from V&H and engine parts are starting to come in.
