Chain Guard For Bikes Question??
« on: July 11, 2008, 08:44:24 PM »
I have a question about the sprocket edge to sprocket edge rule for the chain guard. The rear is easy, I have a Tiger racing guard to put on & it goes all the way back. Guy got me an extension piece to extend to the front, but I'm not sure how far front I need to go.  For the front, if you get too close to the engine case & countershaft cover, I will have clearance issues as the suspension moves. How close do the Tech's like to see the guard to the cases? I have an 07 GSXR1000. Thanks to anyone that can educate me a bit.  :?

You're thinking correctly on the guard length rule. Any rule compliance that can "cause" an integrity issue or a possible failure (and ultimatley a component safety concern like suspension movement making a chain guard contact the rear of the frame which can stress the mounts of the guard itself), needs to have each bike looked at on a case by case (or in this situation, model by model) basis.

Your GSXR will only be required to have a guard extending from the rear edge of the rear sprocket, to the left rear vertical portion of your frame with the suspension compressed (IE: approximattely 1/2" to  1" short of going inside your frame while unloaded). Your frame and subframe in this case, creates vertical coverage with the required material for the rider's protection, so there are no compromises in the rule in doing so. You may also allow the guard to extend forward beyond the frame, but we reccomend to everyone in your situation to notch their guard (same distance would apply),  so it does not rub on your frame. 

Terrible reference pictures follow, but if you'd like close ups of either feel free to ask... and don't hesitate to call the number on the ECTA website regarding MC questions.

Excellent question OldFart..... looking forward to meeting you if I haven't already.
Our outlook is that an effective chain gaurd should allow the chain to freely exit the bike while at the same time protect the rider and any components that could fail if struck by the chain(IE:the brake line, n2o lines, etc).

Thanks, that was exactly what I needed to know. I haven't met anyone yet,(a newb to LSR), but have talked to John Noonan & Todd Dross, & Keith Turk on the phone for some help so far. I'm trying to do my best to show up fully prepared to pass tech , & rock & roll. I don't want to be the clueless new guy running around all weekend, like a chicken with it's head cut off, imposing on the experienced guys, trying to get my bike prepared. I talked to Keith about perfs on my leathers & Keith had asked me how he would remember me at the meet, I told him I would be, "The tall, skinny, a**hole", hopefully that will make me stand out? I think he will remember. Looking forward to meeting everyone in Sept. in Maxton. Bob Leesberg

Nice to not be the ONLY one, but I don't feel as special now that I know there are two of us. Hopefully Keith can tell us apart still. :-D

That is the problem with these screen names, you have to remember two names for everyone and some of us have a hard time remembering one  :cry:

Say DahMurf, if you get around to it would you introduce me to that Deb gal,

Thanks for the pics Todd & Deb. Todd, appreciate your time the other day on the phone. I was surprised at the depth of your answer as NARIDER, now I know why. I thought about calling you again, but I'm trying really hard to not be a pain to anyone. I know how it is when it's volunteers doing all this. I guess the trophy girls (& maybe a trophy guy for Deb?) & all the huge purse money make it all worthwhile. It was the same thing kept me autocrossing. Cool video of you Deb, I caught that the other day now that I'm figuring out who's who. Thanks again for your help.

Sum, cut Willie some slack!  He's already told us that his typing is challenged and that sometimes he uses Sheri's sign-in so he doesn't have to hunt-and-peck his way to his own sign-in.  If we had to wait for him to find himself each time -- we'd still be waiting. . .  See, Willie?  Some of us do pay attention to your stuff.

Just for your comment I'm gonna do it -- I'm gonna go take a photo of a billboard that's been calling to me (for you) for quite a while.  I'll get the photo up here later...
