Slash cut pipes with Nesba

I've been pm'ing a little with gkotlin and wink regarding this and figured I'd post up in case anyone else runs into the issue. A couple weeks ago at Putnam I was told that my slash cut style pipe would not be allowed on the track (upper right of attached shot)



I emailed a number of people asking what needed to be done to the pipe to make it legal. If the edges needed to be rolled like you would a pair of jeans, or iif the pipe just needed to be rounded down a bit, or what. Didn't get too many straight answers...checking through the rule book there's no mention of it. In one response I was told that slash cut pipes were not allowed and in another they were allowed but had to be modified. Finally I asked what needed to be done and what the guidelines were to make that pipe legal and not have to go out and buy a new one. Mark Stern got back to me after checking and said to go ahead and run the pipe unmodified since there was no official rule this year against it. So if anyone has a similar style pipe, looks like it's ok to run for now...but my guess would be the rules will shift next year. So just an FYI since it was totally news to me to show up at the track and fail tech inspection for it.

You got to be kidding? They are worried about the way a muffler is cut, yet I have seen some of the most giant hoopties held together with zip ties and bubble gum run through tech no problem.

Anything that is sharp and protruding is asking to get shot down at tech. In a crash (god forbid) if that pipe gets slammed into someones leg or body they are fucked for life.

I see the point, of course it's a safety issue. But slam a foot peg into someone and it's going to cause it's own fair amount of damage. Plus the pegs like the ones that came on my bike have a nice amount of little pointies all over them. I mean the pipe is short...real short. You'll slam into my foot peg long before hitting the pipe.

As time permits, I'll just take it in to get that back edge rounded a bit and call it a day to avoid the problems in the future.

So... no official statement at this time as I can't speak to this policy for NESBA. However, my understanding is that safety if the key issue. For example, if someone comes through tech with rear pegs still on, we recommend that they zip tie them up, or remove them (note: this is a recommendation, not a requirement)

In regards to the slash cut pipes, the issue is that it is sharp and could easily penetrate in the event of a crash or bike to bike collision. I understand the reasoning, and believe that many organizations are looking at putting a safety rule in place related to slash cuts.

Specifically identified in the NESBA handbook is the requirement for balls on the ends of levers. The purpose for this is to ensure that the lever has a lower likelihood of penetration. Although the slash cut is not in the current rule book, my understanding is that it is not going to be allowed at Midwest events. Remember, the Director still has discretion on safety, and that is his/her utmost responsibility.

Either way, the thought process should be, how can I make EVERYTHING as safe as I can in a known unsafe environment? Rounding the edges like the tip on most exhausts would significantly reduce the safety hazard.

Ok... I am not wanting to stir the pot on an "un-decided" decision, but I need to ask;

With the Blackhawk event coming up on July 14, is this style pipe going to be allowed through tech? I have two friends - which I am sure others do as well - who have this type of pipe (if I guess right it is a Jardine) and would want to know whether or not they are going to pass tech or not?

If I am also a guessing man, if it comes down to cutting or grinding a $500.00 part on their bike to ride the track with a specific organization, they may pass on the organization before modification.

Again, please no one take this the wrong way - I am only attempting to look into the future here. With the advent of motorcycle popularity and the Moto GP style of pipe, I would hate too see riders buying manufacturer upgrades only to learn that these type of slash or bologna cut ends will not be allowed during track events.

EDIT: These are probably the most popular pipes to be purchased that will become the basis of this decision;

Jardine, TiForce, HotBodies, Racefit, BOS, Muzzy (some) and MIVV (UK model). Also, just about any upgrade muffler with tip supplied for current model year Buell's will have a slash cut single cut, non-curled lip, exit as well.

Yeah, but is it really a safety issue if it goes into your body through an existing hole? Your body hurts cause your not using enough lube.

I'm all for safety but i think this is a bit overboard.

If slashcuts are banned, what about footpegs that have been crashed on.
I see a lot of those in the paddock, and the danger is the same.

Sure, you wad it, theres a chance you will slice your leg open.
Theres also a chance you will break 5 bones in the process.

Its a very dangerous hobby. I dont think banning a particular type of exhaust system is gonna make it any safer.

Im curious to know if there have been any documented injuries due to slash cuts. Seems to me it would be highly unlikely to be cut by one in a crash.

Tom,

For what it's worth, after a crash, bikes are supposed to re-tech. A ground down and sharp footpeg should NOT clear tech. After my last crash, I couldn't go back on the track until I replaced my newly angled footpeg.

And FWIW, the danger is not the same. A three inch spike will cause significantly more damage than a half-inch spike. Both are dangerous.

As said above, our job is to minimize the risk of what is controllable. We have many complaints about not allowing levers with out balls on the ends. "Hey, I'll sand it down.", "Hey, I'll put duct tape on it." Neither answer clears tech.

Reality is, NESBA will make the determination of the rule. Whatever it may be, we will try to enforce all of the tech requirements uniformly. The issue at the moment is that we don't know what the decision will be.

In the meantime all we can do is wait. Some will hope that slash cuts are approved. I will hope that they are not. Whatever it is, once it is determined, people can make their track organization selections as they wish.

That is great to hear Tom! I don't think I have ever heard anyone at NESBA event referred to as a customer. Only as members, or family.

Ok so I got an official response from Fred, one of the directors. He apologized for making a mistake. Apparently this was only in the discussion phase and he thought it became rule this year. He said to disregard any rulings on pipes and that my pipe was and continues to be perfectly legal. Either way I'll print out all the emails and bring them with me just in case.
