Stop picking on the poor fella. Dont worry about it spencey Im no expert but I've never experienced problems due to air in the fuel line I've gone a few yards down the road and my engine suddenly died because I forgot to turn my fuel switch on whoops boy did I feel stupid then but the fuel is constantly flowing through the pipe as long as thats the case then a pesky air bubble doesn't matter listen to kevtherev he's already answered your question.

Thanks man interesting read so basicaly it is possible then just a bit of work and a few parts required I still dont know if its coil is running 6v or 12v but no worries I will bring out my multimeter when shes in the garage and do any mods if and as neccessary I will keep you updated when I get it done thank you slice.

hey guys I've got a technical question for you my DT 125 LC mk1 1982 which I recently purchased has a 6v battery which I'm thinking of replacing since not only does it need a new one but I wish to run a digital ignition (keyless) system and alarm that requires 12v I dont want to have to add a secondary battery I'd like to replace the current one with a 12v battery instead since unlike sport bikes theres not much room to hide things. The bike is currently being restored by myself and my father with occasion help from a mechanic so project "difficulty" doesn't really matter as long as its possible I'm thinking of changing the speedo to something more modern like a digital one from a YZF R125 or XT 125 later on too. Here are my questions for you guys. Can I replace the battery with a 12v one with or without replacing parts/modifying etc?. The service manual I have says that the lights and horn run off of 12v not 6v why then does it require a 6v battery? Just to add I have already connected a 12v power source and the neutral light, the oil light and horn function correctly I am currently unable to test the indicators due to a previous owner making a mess of the wires and even changing the power cables (no inline fuse as far as I can tell) oh and I am currently unable to start the engine since the bike is sat in my living room till next week hence my eagerness to sort out the electrics before the stripdown and powder coat etc. Any ideas or thoughts on this matter would be greatly appreciated. Many thanks. Karas288

Forgot to mention I think mines a mk1 and it seems to have the YEIS system but sadly does not have the YPVS system if anyone would like info about this model of bike then let me know and I will try to help as much as I can I've got the service manual for it.
