Gymkhana

The timer itself is pretty accurate, and holds a lot of laps to scroll through. However the triggering system is a bit cumbersome to set-up and sometimes doesn't pick up the signal, or can pick up some other infrared light source and start/stop your timer in the middle of the lap. I found it works for me about 90% of the time, and when it doesn't, it usually just needs a readjusting on the bike, or old batteries in the beacons.


As far as using this timer for GP8, yes, you need two beacons, set up on both sides of the start/finish line.

Those beacons are nothing more but an infrared light bulb. You can probably just get it at Radio Shack and strap it to a battery.

With regard to quick & easy timing systems, I have found something that I think will do the trick.

I have written to the organisers of the event that this kit was built for to try and track down the designer. If I can persuade him to reveal his parts list and a wiring diagram then I will post it up ASAP.

This might have gotten lost, as it was the last post on the previous page, and might have gotten skipped over as the page turned, but this link has instructions and wiring diagrams for exactly what you guys are looking for.

As I said, the only reason I haven't built this, is that I never had any experience with assembling electronics.

I tried to outsource this to a few people I knew, but it never got off the ground.

Not that this will help much since they are cheap, but I have a bunch of cheapo stopwatches if anyone wants to try this I can send or meet up to give one or two to someone.

A variation on the Moto Gymkhana theme is Duel-Attack, a bit like drag racing only with a high degree of bike control involved. This video is of our group in Vietnam just having fun by running it as a team event.

I really like this idea. As much as time attacks are, a head to head competition is a good change of pace. We are definitely doing something similar this summer.

this other photoelectric switch timer system looks simpler to make: http://translate.googleusercontent....1.html&usg=ALkJrhgIzDaK_U_q8mRZGwPpjhuUsA7W4Q

Good practice session today. Vulfy, YamahaRN - any chance you guys have pictures from today?

It had been a long time since I did any gymkhana, but I made some time to get out today.

I took this fat girl for a dance:

I put the ones I have on the fb page.

Thanks!

how about putting it here, so three days from now when Facebook changes something we'll still have access , please?

Why not use something like this, so nothing has to be mounted to the bike?

I was looking for something like this, always see these things taped down on the roads! Had no idea what they are called or what to search for though. Thank you! Will definitely research more into in now.

The only picture I got with a cone and a bike.

I'm late to the party but very interested in something like y'all have been discussing. It would seem better and cheaper than buying a lot of modules for the timer that I have now. I have added a second beacon to my front fender so that it will transmit in both directions to start/stop the timer regardless of which way I'm traveling. It works, but it'd get expensive quick if you had to have more than a few and then figure out how to mount them to various bikes for an attack event. I didn't mind putting velcro adhesive tape on my fender, but a lot of riders might flinch at that type of mount.

Any news on this new device?

This is the timer that I am using now.

zip tie to the fork leg?

I had an audience for a while today:



I think I dragged an exhaust pipe on my cone?



The biggest limit to the V-star seems to be the cornering clearance. It drags the pegs pretty easily.

Going to give it a whirl this weekend. Thanks for the inspiration.

This may have been covered earlier, but do you guys warm up your tires beforehand?
