I\'ve had my battery for 3 years,and recently i\'ve been having starting problems,it won\'t even jump start of other vehicles.i\'m assuming the battery just needs replacing-hope this is the case-it\'s a 12a with efi controlled by microtech.It started once after charging the battery,but it doesn\'t start off a full charge-it turns over well enough but doesn\'t fire,but sometimes fires a little,but not quite enough.Also,the exhaust has gone quiet,and performance has dropped considerably.Tim RX Motors reckons the lining of the exhaust has gone(from my description).It\'s a powerflow full system,i\'ve heard complaints on here about them before.Hope someone undestands what i\'m crapping on about.
