Member Contributer fink Posted March 27, 2016 Member Contributer Share Posted March 27, 2016 Check the starter relay. There was a recall issued over some starter relays. I can't recall which years were affected. Link to comment Share on other sites More sharing options...

I can't recall which years were affected. ok what i be looking for on it???? but that makes sence as the main power goes threw it. just round the recall letter on the www and decoded the date on the bottom of the starter relay and think it may be a bad one. this is link to what i found http://www-odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/UCM483041/RCRIT-15V439-3871.pdf Link to comment Share on other sites More sharing options...
fatshoutybloke Posted March 27, 2016 Share Posted March 27, 2016 Yes, mine occasionally does that too. Exactly as you say, random times and always starts immediately at the next attempt. Link to comment Share on other sites More sharing options...
Member Contributer Grum Posted March 27, 2016 Member Contributer Share Posted March 27, 2016 Yep, had it on the odd occasion and seems to be on cold starts. While I don't have the specs on the starter motor, it seems to be (from memory) smaller than the 6th gen, possibly lacks a little grunt, never had this effect on any of my three 6th gen versions.

phatstorage Posted April 2, 2016 Share Posted April 2, 2016 Mine's done it pretty much since I've had it, ignored it after a while as it's not got better or worse. Link to comment Share on other sites More sharing options...
mrmessy800 Posted April 13, 2016 Author Share Posted April 13, 2016 well mine in going to Honda this sat so they can have a look (plug the laptop in) Hope it does it when they try and start it Link to comment Share on other sites More sharing options...
dogman Posted April 14, 2016 Share Posted April 14, 2016 What grade of fuel are you guys using? Mine has never done this and I have had it almost 2 years now, I think this engine has more ignition advance or compession than the previous use in 6th gens, and I am wondering if a little preignition while cranking is stalling the engine and causing electrical overload. I have always run 98 RON which would less likely to preignight, but I am only guessing. I have a stihll chainsaw that does this as well when starting and that is not much fun...

Hmm interesting thought dogman. 6th Gen specs = Compression 11.6 to 1, timing 15deg BTDC at Idle. 8th Gen specs = Compression 11.8 to 1, timing 8.3deg BTDC at Idle. Surprising the 8th gen is more retarded (timing wise!!!!) than the 6th gen. You might have a point with the fuel octane, can't say wether it's done it more on premium or standard 91ron as I have played with both. I will definitely take note of when it happens next and the fuel I use, though I seem to have this starting issue very rarely. Still got my doubts about the 8th gen starter capacity, reckon it's smaller than the 6th gen. Cheers. Grum Link to comment Share on other sites More sharing options...

I have a stihll chainsaw that does this as well when starting and that is not much fun... i do run both types of fuel. and it is very much hit and miss when it decided to not fire. i do think it might be the starter solined as when it happens everything cuts out on the bike. and the main power runs threw it. so if its week it would cut everything. thanks for your thorts but ill see what Honda Bromsgrove say and hope the ecu has logged a fault.

fatshoutybloke Posted April 15, 2016 Share Posted April 15, 2016 I never run less than 95RON because that's the lowest you can get here and mine does it sometimes, so I'd say it's probably not that. Link to comment Share on other sites More sharing options...
mrmessy800 Posted April 16, 2016 Author Share Posted April 16, 2016 up date honda found no fault found! ecu not logged any fault codes. so they checked all connections cleand them inspected starter solined checked battery. nothing so as they know about it that have another look when its in for her service.
