Sorry to disappoint but by fingers went into a back sprocket when I was about 12 , still got all 10 functioning well ;)

I agree the act of fitting something is a minor feat of engineering  ;)

The problem is and im generalising  here ( just to be clear that im not digging out MA or anyone in particular ) is that our generation needs to stop taking it up the arse over every "little Opps that might happen" bullshit  ::)

I know that 99% of you wont get it as you are happy to sell out to the system as long as the system delivers it in little jabs rather than a big left hook.

This is how OUR  generation has let the PC monster creep in and control our lives . Our fathers were real men who fought for what they believed in and went to war ( real wars not rich pricks and media funded bullshit oil wars )

But we roll over every time someone says  "BUT IT COULD HAPPEN" and say yes sir no sir 3 bags full sir . I am ashamed and embarrassed by my generation   :-[ ( we are a generation of Pussies  ::) Dog help our kids and their kids  >:(
Its only old bike racing FFS get over yourselves

I agree Bill.
 Pretty soon the litigious will have the world riding Vespas made from Nerf.

 Motor racing is a dangerous sport and we accept this as a consequence of the sport.if you dont accept it dont do it...Simples.
I cant wait till riders get red carded for not having both wheels in contact with the ground or excessive wheel spin.

Kind of funny that my Road registered machine does not require a rear sprocket guard just a chain guard and i dont have to wear half the protection i do if engaged in a sporting event.  Yes protection is wise but enforcing the fitting of an alien device to a machine based on historic correctness is shooting yourself in the foot...... naa thats dangerous too.

Col , I think the point is were does it all stop.   We all sign a waiver to enter each  event and reminded at riders briefing that motorcycling is dangerous and we ride knowing this.

I've always wondered why Vintage riders walk so funny, used to think it was the lack of suspension on their bikes but now I know it's because most are happy to bend over and cop it every time someone at MA tries to justify  there existance by inventing something new.

Think it is quite funny this bit about fingers getting in and comparing it to the front sprocket covers that we only need to have if the sproket is further than 30mm from the swingarm pivot. A lot off the factory covers had holes big enough to get fingers through if you are stupid enough to try(TM an RM suzuki's spring to mind) but they seem to be ok.

Next it will be Lanyard kill switchs like they have forced onto those out of control Trials bikes.

FFS,it's your  boot/foot going in, not fingers,might have started off on tar 1st,(Beatty lost top of his foot on the factory yamaha when he crashed shoving his foot into the rear chain),same deal with open primaries,hate to have 3 spring AMC clutch do a number on my leg when it all goes pear shape,(oh look,NEB's are flush  ::)),s/cars use lanyards,so too a few guys on tar,(generally you only havta experience "shit happens "once to get the gist of it??), :P
work,the curse of the racing class!!

again its all good until the lawyers step in...your a fully employed fitter and turner working a specialist lathe and one day your short 2 fingers... (unhappy wife for a start!) then you get the boot... what do you do? no job, feeling shat upon? you can complain about PC all you like but every bugger in this spot immediately googles See you Later and Gordon. then all the poor bastards down stream get bent over big time.....real cash real court orders etc. just grin and take one for the team....

Not debating the need for the guard was only looking for a bit of guidance as to where I could do a couple of cut outs . Don't want to arrive somewhere and find someone says it's not legal because.......
Not trying to over complicate things, don't want a philosophical debate just some guidance from those about. As  I said guard was easy to fabricate and mount cos of an existing bracket, just wanted to do a couple of cut outs to take the junky look away as it mounts from the midpoint of the swingarm  on a slider. Engine sprockets I reckon are a different matter as slots, holes etc shouldn't see finger protrusion but they are much smaller to what I'm looking at.

This rear sprocket guard is the biggest load of crap in the rules.

Blah Blah Blah to prevent trapping between the lower drive chain run and the final drive sprocket Blah Blah

Last Friday afternoon i stood there and watched 73/74 Hondas breeze through with their chain guide halfway down the swingarm wIth at least 6 inches of nothing behind it up to the sprocket teeth.

Then I witnessed two Huskys knocked back because their chain guides were fixed to the brake stay
( standard ) and totally enclosed the front of the sprocket. They were made to CABLE TIE a cutting from a fruit juice bottle to the swingarm to get through scrutineering.

its not selective anything; to the observant you would have noticed that CMX was exempt for a couple of years while the Commission sort to define what it was that we would have to be compliant to. It was decided (and I agreed at that point to add to the GCRs) that if a bike came from the factory with a chain guide that was fitted to the swing arm such as a CR or a TM125 then it would be acceptable. If as in the case of the Husky it wasn't (on torque arm)then something will have to be added. If a bike had nothing then it would have to have something - my AJS is a classic case.
That someone out there decided that it should look like half the stuff I saw on the weekend isn't my problem, some guys did a great job but others with nothing (and there were quite a few) were asked to do something about it.

The rule is a reasonable rule and was put in the GCRs after a flag marshal at a road race received an injury when picking up a fallen bike.  Darryl Beattie also lost all the toes a one foot after a freak accident on a GP500 bike.  So the potential for permanent injury is there.

So if a flag marshal grabed a hot exhaust and burnt his hand? Or he was hit by a bike?
If someone grabs the sproket their finger are going to go between the spokes and the sprocket and still get jamed up even with the cover on the outside.
Wouldn't it have been better to tell flagies not to touch fallen bikes?
What about the top of the sprocket incase the bike rolls backwards?
Sorry but your reasoning hasn't convinced me that this is a good rule and I still believe we are being screwed.

Peter Sunderland told me he was shown the x rays of his scrotum,(apparently you could see the valve collets plainly),think thats why scatter sheilds came in for drag bikes,(his rebuilt JAP went back to Alf Hagon as birthday prezzie, from memory ::)),
turn 6 East creek,matcho spits the primary chain,i quickly park,go running back down track waving arms,yelling at marshall,DONT PICK IT UP,he picks it up,burns the shit outa his hand,then after dropping it,kicks it into the dirt inside track,(it was nowhere near the race line!!), :P
work,the curse of the racing class!!
