From the rulebook:
9.4 LOCKWIRE REQUIREMENTS
Because historic racing motorcycles have unique characteristics of construction, AHRMA has developed specific lockwiring requirements for roadracers. As a general rule of thumb, “If in doubt, lockwire it.” Note: Only stainless steel lockwire may be used. The following regulations apply in addition to those listed above.
a) Primary case filler, drain and level-check plugs must be lockwired.
b) Crankcase filler, drain and level plugs must be lockwired.
c) Transmission filler, drain and level-check plugs must be lockwired.
d) Any primary case, crankcase or transmission inspection plug must be lockwired.
e) Any primary case, crankcase or transmission overflow or vent hoses must be lockwired.
f) Oil filter nuts and oil filter plugs must be lockwired.
g) Fuel tank overflow lines must be secured and have a catch bottle or one-way valve provided.
h) Lockwiring of carburetor drain plugs, or securing with a fuel-proof sealant, is encouraged.
i) All flexible oil lines must be a reinforced oil and gas resistant hose, and must be secured by lockwire as secondary security, in addition to a swaged fitting or hose clamp. Total-loss oiling systems must be equipped with unbreakable catch bottles and/or a “select pad” diaper system.
j) All fuel and oil lines must be securely clamped or secured by other acceptable means, and will be pull-tested during tech inspection.
k) All fork drains must be safety wired or securely taped.
l) Exhaust systems must be securely mounted and bolts lockwired. A secondary security system is encouraged and may be required at the Tech Inspector’s discretion.
m) Brake torque arm bolt lockwiring is required.
n) If not lockwired, axle nuts must be secured with a cotter pin or other acceptable means.
o) Foot brake pedal pivot bolts and nuts must be lockwired.
p) All brake rods and cables with threaded adjusters must be wired or cotter-pinned to prevent the loss of the adjuster nut.
q) All throttle cables must be secured to the throttle housing by lockwire.
Oh yeah, and don't forget a belly pan...
Honda go sideways!

Scott,
Specific to the Honda 350, here is what I have done to mine and have never had an issue at AHRMA tech.
Front fork axle pinch nuts
Fork oil drain screws
Brake stay (both ends)
Throttle cable
Exhaust nuts
Oil drain plug
oil filter screws
oil filler plug
fuel lines including tank crossover (I don't use clamps)
rear brake stay (both ends)
rear axle hitch pin open ends
rear brake rod adjuster nut
For oil containment I used a paint roller tray attached to the stock footpeg bolt holes and the front motor mounts. Don't forget a breather catch can for the breather hose off the valve cover.
Where are you gonna race?

kenessex:
Not to hijack the thread too much, but what do you do for the fuel line crossover? I've capped it off/wrestled with that damn fuel line long enough. Any leads on quick disconnects?
P.S. Chances are real good I'll be at Grattan for race school with YM Racing (They seem like real nice guys). New Vanson suit on the way, even gonna get me a brand spankin new Shoei jes fer racin.

Krapfever,
I cut both of the crossover outlets off short so they didn't interfere with the frame as much. Then the crossover lines can go on with a more vertical approach. They are still a pain in the ass, but still easier. I also use a longer peice of hose. I don't care if it hangs way down as long as I can get it on and off easier. I am still considering just capping the fitings off entirely and not worrying about the last few ounces of gas, except I don't know how much capacity that will really cost me. Of course in an 8 lap sprint if I am stupid enough to not fill up my tank so I can finish a race I deserve what I get.
I will be at Grattan, come find me. #412 I drive a red Ford Escape with Alaska plates. I will probably pit by pit out of the practice day between turns 4 & 5 by the jump. I plan on being there for the practice day on friday. What classes are you going to ride?

Scott,
Do you have any info on the track day at Blackhawk? I will only be about 4 hrs from there. When is it? How much for the day? Do you have contact info for whoever is running it?
That used to be my home track, but I haven't run it in 20 years. It is a great track for a small bike.

McMaster Carr and MSC have Delrin QC fittings with various ends on them. You can use the small ones for the crossover but not for the mains. I did and my 175 was running out of gas. Oh, you have the change to "O" rings to Viton, the originals swell up in gas.

Scott,
I've met Bib Bob at Grattan and Mid-Ohio. I'll email him and see if I can come down and play. That is a little short notice since I am stoill in Alaska right now and won't be to WI until the end of next week. I doubt I will have my Seca 550 ready by then but the 350 should be ok.

thanks for all the help from you all. especially krapfever and kenessex. ken actually showed up for the track day at blackhawk farms to ride while i was "in class". he gave me a bunch of pointers. i love how the vintage motorcycle community leaps to help out the newbies. hopefully i'll be seeing some of you at grattan.
