Hi guys, This is sure to be my first post of many as i am new to the motorcycle game. I bought a FZR-250 '89' 2kr with EXUP with 13,000 km's on the clock (genuine? who knows) and because it was hardly ridden, the battery wouldn't charge so i replaced that. There is also a rattling sound from around where the EXUP valve is, does this mean it needs a tuneup? Yesterday it was a hot day and rode to the shops, when i stopped the temp gauge was basically in the red came back half an hour later and jumped on to go home and the bike would not rev. I legged it home going about 40. It can rev to about 8k and the hotter the bike gets, the worse it gets. It starts to miss and if i give it full accel, it will just stall. I have also noticed a rapid clicking noise that seems to be coming from just in front of the fuel tank that will speed up with the revs which made me suspect a coil/ignition issue? I was putting premium but after ringing my local bike place they advised me that with the old school carby bikes that can cause blockages and could require a strip down/rebuild. I was going to do a full service and reassess the situation, but if any of you guys could shed some light that would be great. I have read extensively on here about various issues, but couldnt find any like mine. Thanks!
