Thanks for the reply. You're right about the earth (in this case the horn) being non centre as I followed the only two wires from the switch to under the tank cover. The prior owner told me that two buttons needed pressing to kill ignition but the switch body had to turned on the handle bars a little sometimes. The pressing of the two buttons was to make the ign kill wire hit a curved metal in the switch and the other button hitting the other side of this curved metal thus connecting the two wires. Suspecting a poor connecting or corrosion I cleaned the switch and followed the two wires to under the fuel tank/frame cover and saw one going to the horn and none to ground. After some more investigation I found the wire going to the horn was broken inside the loom so the horn was not connected to the switch. How the bike ignition went to ground then was by holding both buttons firmly down, the curved metal then was able to contact a bare spot on the anodised handle bars to ground out the ignition. Mystery solved. Thank You

Recently bought a 95' Techno with a strange wire setup for the ignition kill. The ignition kill wire from the coil has been rigged to a switch that connects to the horn, then the other wire from the horn goes to the 12v output on the voltage regulator as shown in attached image. The wire colors in the image are the same as on the bike. The kill switch actually works as wired but I wanted to remove the unneeded horn. Shouldn't the wire coming from the kill switch to the horn instead be connected from the kill switch to the ground? Thanks, Markc

I need a flywheel / ignition cover and prefer a stronger (and expectedly less expensive) aftermarket one but I cannot seem to find anything on the web. With the exception of the TYZ250 (which I could not find anything), are there any other Yamaha models that used the same basic engine? Thanks, Mark

I'm not a member of any clubs nor do I have an ACU license. I just bought the bike this week and it's my first trials bike. Mark

Hi Paul thanks for the reply. I've been up to Arncliff which appears to be nearby Halton Gill, perhaps I'll be able to get out there on May 2nd. How does it work, do I just show up? I've seen a place on the right side of the Ripon road (B6255) just past Fellback going toward Ripon, but don't know anything about it, I would love to know more as it's just a couple miles from where I live. I also heard of a place near Ripon and the M1, but haven't been there.

Bringing up an old thread: For the gerabox; is it gearbox oil (which is usually 75w-90), ATF fluid, or 10w-30 engine oil (according to a 2003 owner's manual it reads SAE 10w-30)? Thanks, Mark

Hi, my Name is Mark and I bought my first Trials bike yesterday, an 05 Scorpa SY250. I live in North Yorkshire, near Pateley Bridge and I'm looking for places nearby to practice riding and to learn the basics. I'd be grateful for emails from anyone who lives nearby and/or know nearby places to ride. Thanks, Mark
