Timing set up

[Daffyd]

At last, I finally got my GS back together (6 months...bad weather,little time). Unfortunately it won't fire. The original points were no good,so I fitted my Piranha ignition from the previous engine, can anybody tell me how to set up the timing using a strobe please....if I don't fix it soon there may be a load of GS bits for sale. Seriously, any advice appreciated

What bike Dave? For a GS1000 the book of words says point your strobe at the timing mark at less than 1500 RPM and the F marks should line up. Spin the motor up to 2500rpm and the advance marks should line up. Note that's for points - the Piranha box might have a different set up for advance if it doesn't use the standard advance / retard mechanism.

Sorry mate, the bike is a GS750d /e. The bike doesn't fire at all, the timing is WAY out. Turns, sparks, tries to start, but ultimately doesn't
Fuel is getting through (there was a huge bang, I thought someone was shooting at me).???????????????????

cant give you exact advice for pirhana ignition but just try moving the back plate around whilst cranking it until it sounds positive about firing, then fine tune it. make sure all your connections are good also!

Dave, when you get it running the 750 figures are the same as the ones i gave you for the 1000.

For the static set up Google Newtronics Ignition - Newtronics is the new name for Piranha.

Of course you might just have the plug leads on the wrong cylinders - worth checking.

sounds like the rotor/trigger is 180 degree's out.
if so,
pull it out from the advancer and spin it half way around and re-engage.

Hey guys, thanks for the advice....will let you know before end of week. After re-checking wiring, main fuse was in a really poor state,so that is my first task,will then double check connections. Just off to check newtronics site now, will follow all advice. If all else fails, can anyone lend me an Uzi?????
Thanks again :clap: Dave
