Hi all. Will be running an old twin at Willmington this year. My build is pretty much complete and I used an old SCTA and Lorring book as guides, but just had Tonya send me last years rule book to get everything buttoned up. I know there might be a few changes in the 2016 book but I'll adjust as necessary when it comes out. Just looking for some clarification on a few areas. Figured you guys may know the answers, if not I'll just forward the questions to Keith.
For reference, I'll be running MPS, overhead cam twin.
1- Gasoline Shutoff(7.B.2.4)- I gather from this rule that I can't use plastic fuel filters to my carbs. I have no issue swapping out the ones I have on there, but what's acceptable as a replacement? Glass just seems like a bad swap. I can go without them as I have a filter on the petcock in the tank, but just wondering what others do.
2- Fuel Shutoff(7.B.2.5)- I'm a just going to be running standard supplied gas on my bike, but was going to enter in both G and F. This rule says I need a fuel shutoff that I can operate from the handlebars. If I'm running a gravity fed system with no pump, this doesn't seem possible. So I'm guessing the Fuel class is off limits to me without a fuel pump? Confused here because I could have sworn I've talked to people that ran gravity fed fuel systems in both classes. Just need some clarification here as I may be misunderstanding something with this rule.
3- Controls(7.B.4)- 1/2" ball ends on controls..... Please see picture. I measure my ends at .601", and they look 'ballish', will these be ok?
4- Fuel Systems(7.B.25)- This section really confuses me. I'm currently running Tygon lines (the neon yellow, pricey nice stuff) from the tank to the carbs, all barb style fittings, with wire style clamps. The rule says something about fire proof lines and connections, fire sleeves over lines, metal clamps on flexible lines...... Just needs this spelled out for a newbie, doesn't sound like my lines or clamps meet this requirement. What about the Tygon? The rule says no plastic lines but then the rule says clear lines are ok if they are marked on the line as fuel capable. Well fuel use Tygon (4040) is opaque yellow. I can hand carry the data sheet for the line with me that shows it's fuel certified. I have never seen Tygon 4040 with writing on it though. And if I have to sleeve it with fire resistant sleeve anyway.... I did see a few posts elsewhere on the forum that lead me to believe that sleeving and clamping the Tygon will be acceptable, but I want to make sure. Only 6" of line, but I suppose it's critical to get right.
My carbs have vent lines and overflow lines as well. Didn't see anything in the rules about these types of lines as they are not directly part of the fuel delivery system. Do I need to sleeve those as well or can I leave them bare?
5- Rear Fender(7.F.4.2)- See picture. My seat reaches the rear axle (barely) so this should be sufficient for the rule, correct?
General question, how does the weekend work? What I mean is, do I have to pack up my bike and overhead cover each night and take it with me to the hotel after the day is over? Or does it all get left there as is with security... Or can I just sleep in my truck bed and skip the hotel?
