Hello all newbie here Got my self a mutt mastiff 125cc...and I changed the rear indicators the other day as the factory ones keep burning out...so anyway I followed the old wire and put the correct leads in the correct sockets everything was fine ...goes to put seat and idicators together again via a bolt IVA side and there is sparks coming from the bolt as I turn it ....what could this be ?...it's in the garage now but I am wondering if anyone has an idea what could cause it or have they had it happend ..the bike still started up and the indicators worked fine for about 20 mins

So I have had my titan for just over a year now and the most serious problem happend the past two weeks. It is struggling to start in. The mornings or when it's stood for a while, and once it does start it cuts out every now and again... Going over bumps (only sometimes) the revs will drop out with out me taking my hand of the accelerator, takes a while to gett it back to normal revs and moving.... And today I hit a bump and that was it I had no power going to my dash, key wouldn't work and kick start would not iva, no lights no horn no nothing.... Tested the fuses they had power going through so I'm stumped to what it may be anyone got ideas? Many thanks in advance
