Posted February 15, 200916 yr hello i just brought a yamaha rxs 100 ive brought a new battery/ spark plug ignition coil/rectifier now my hard part is the only wireing i have is from the engine its self ie i wanted to do a field bike as i have a other swing arm and its lowed at the rear and got a nobby rear tyre on now my hard part is what wire goes where to get a spark i have 5 wire ie 1.black 2.red/green 3.blue 4.yellow 5.green plus in the manual it says on the wires from the engine theres a code saying SB what does that mean? does any one know how i could wire it up useing the new bits i got ie the bloke at the motor bike shop said i needed these bits but i dont need lights etc i just want to have a rocker switch so i can turn it of to cut the engine out etc if you know what i mean hopefully some one can kindy share some light:) cheers rob

These bikes dont need a battery to run, so there will be no need to fit it along with the rectifier these 2 items are there to run the brake light, neutral light, horn etc Regards Jim

February 20, 200916 yr heres a engine code pic and the bike pic i said which is not a standed yamaha rxs /rx 100 bike! Hi There, 1Y8 is the modal code for the RS100 the RXS100 code was 31J, but from your photo's it would appear to made up of bits from an RS and and RXS. So all you need to do is run the black wire from the engine to the switch then on to the coil, As this bike doesn't need a battery to run and looking at the photo where are you going to put it The only draw back from this is that lighting/charge coil may go O/S but as you have no need for lights or battery charge it will make no odds Regards Jim

February 21, 200916 yr ive done that what you said but i cant get no spark is there points in the engine to sort out? if so what gap does it need to make them work Yes there are points in the mag, the correct way to set them is to turn the piston back from top dead centre (piston at the top of the bore) 1.8mm at which point the points should just open they are not gapped,as such, to a figure Regards Jim
February 21, 200916 yr Author hello rob i`v been watching did you get her to started? hi there no not yet due to other owner before me has welded the gear peg ie got to clean the metal pole so i can take the side cover of
February 22, 200916 yr hi there no not yet due to other owner before me has welded the gear peg ie got to clean the metal pole so i can take the side cover of that's a bugger rob had same problem with kick start on one of mine, luckily he just welded the end so it was a case of just grinding the end off then gently easing it with a chisel in the split, i tapered the end of the shaft with grinder before fitting new lever. hope you sort it glen
February 22, 200916 yr hi there no not yet due to other owner before me has welded the gear peg ie got to clean the metal pole so i can take the side cover of Hi you dont need to remove the gear change pedal to set the ignition timing ...... just remove the smaller case/cover to give access to the mag and set it as I said in prvious posts. You need to check that your on/off switch is working so wire the black from the mag directly to the coil .. if it sparks the switch is at fault (or the earth to the switch) either way you can sort that one out. If you still have no spark you will have timing problems or perhaps the heel of the c/b points has broken off ... which was something that happened to the RS motor when someone dogged a screwdriver into the mag and adjusted the C/B points in an incorrect way Regards Jim
