Hi everyone, Thought I would share and see if anyone has any ideas or remedies. My KTM RC8R has been a slow starter the last week or so.. Usually when cold, I push the starter, hear the relay click in and the starter motor tries turn the engine but not enough to even think about starting (it started as just enough to kick it into life...) Once started it is charging itself well and being warmer I can park up, go shopping and it starts on the button. When kept in the garage it is on an Oxford charger etc. I took battery off, had it tested and told it was good (showing 240 CCA) However put it back in bike and it wouldn't start so in brain wave I took out the fuse to kill the lights and hey presto it started!! But fuse back in (good job I have spare key to lock seat down!) off I went stopping and starting no problem... Next morning.. same problem! Phew that was long winded! Anyhow can someone confirm that despite battery seeming to be good, it is not holding enough charge to cold start a big V-twin, or perhaps there is something else I can check?? Any suggestions welcome!! Thanks
Hahaha Hiya Babyblade Just poor quality Yuasa batteries and a big old V-twin I think! I tried push starting a few times... waste of time - just wore out the back tire skidding and killed myself trying to get up to speed!
Hi Yarg I have an alarm and separate tracker but they are completely dormant unless manually switched on.. As tracker is independent to battery. Only spare battery I have is an old one which was replaced. But I could try scrounging one to test needs a high CCA though.
Hi RC8R How old is the bike? It could be the starter motor itself, a build up of carbon on the contacts. If ya can access it, try a few gentle taps on the starter, if improves the starting, you'll need another starter very soon as its a temporary fix. If that don't work, I haven't got a clue, bike electrics are a dark art. Good luck
Hi all RC8R again Firstly sorry to Nellie for not thanking him for his advice... I lumped my reply in one and reply in with response to Yarg.. oops! Second, Thanks Floyd... The starter is on top of the engine, between the pistons, under the airbox / tank, behind brackets.... I think you get picture!! I am coming to the conclusion that the battery is struggling and a small lay up... Which brings me to my next question... The recommended battery is Yuasa as it has 230 CCA. Obviously the bike needs the extra oomph... My ask is... Does anyone have experience with the Lithium Ion replacements.. the cost isn't much different, They are 2kg lighter (more doughnuts for me! :) ) and the CCA is 290.. So should start easier.... I know they need a special charger.. but you can boost charge them.. I would like peoples thoughts... Cheers
