As I stated in the title my engine won’t start. I was riding home from work yesterday when I noticed the engine felt a little rough. When I tried to accelerate onto the highway the engine stalled. When I tried to restart it it would crank and crank start then immediately die. So I had to pay for a tow truck. I changed my own oil at 600m like it says in the owners manual and I’m 100% positive that I correctly installed my new OEM oil filter and filled the oil too the proper level. My question is, what could it be? And do you think Honda Powersports will cover it under warranty?

I bought this stupid thing expressly for its “reliability”

It could be a number of things but luckily for you the bike is still under warranty so the easiest option is just take it too the shop you bought it from and let them diagnose the issue. If they are a good outfit they may even come and collect the bike. If you put the oil filter in the wrong way round then you would have had issues pretty much immediately. Coolant level OK and bike not running hot?

 

[8lincoln30]

Coolant level is fine. It didn’t really even have enough time to overheat. The only major difference was that I noticed a lot more vibration in the handle bars before it completely stalled and wouldn’t restart. Thanks for the reply

Ok keep us posted on the outcome for the purpose of learning something.

 

[8lincoln30]

Will do

 

[motorboy]

just to be on the safe side recheck the oil filter-because if you bring it to the shop that is the first thing they are going to check

 

[8lincoln30]

Well I already took it too the Honda and they said, if it was the oil filter the problem would have happened almost immediately” and I’ve ridden it for more than 300 miles since the change. But thanks for the reply

I'm assuming your Honda dealer has the bike now. Unless there is obvious abuse, the problem should be covered under warranty. My guess is the problem will be in the fuel or electrical systems and have nothing to do with the mechanics or durability of the engine.

 

[8lincoln30]

Thanks for your response airhead83🤘

I’ve been running 86-87 grade fuel. It says in the owner’s manual 86 is the minimum octane rating. And I don’t see any reason to use 91 or better. Could this be my problem? Because I’ve read some of the CBR300R guys run 91+

 

[kiwi rider]

No, it's not the grade of fuel, something more serious.

So my local dealer says it’s probably a faulty oil pump. I guess that means that it was running dry. My question is if my oil pump failed, then what are the chances that they actually need to replace my entire engine, since a dry engine cylinder walls and piston is probably totally F’d in the A? Currently they’re just going to try and replace just the pump. Is that the correct plan of attack? Or should I demand a new engine altogether?

You'd have to see the internals of the engine to know the answer to that question but yes, if the oil pump failed fully then you'd expect the engine to be totaled. But if it was only a partial failure then the engine could still be OK to varying degrees.

 

[airhead83]

I'd play nice with my Honda Dealer and let them sort it out. Once your dealer gets into the engine, there's really no reason they would need to take shortcuts since Honda is footing the bill. I'd like to believe they would do a proper repair.
But I'd insist on some reassurances Honda (regional, district, somebody above my local dealer) has the problem on record, so any near future problems would still be corrected and paid for under the original warranty.

 

[8lincoln30]

Does anyone know the typical turn around time on a warranty repair of an oil pump?

 

[airhead83]

It will mostly depend on how soon they can get hands on the oil pump.
The dealer's service manager should be able to tell you it's available through normal channels... meaning 'a few days or weeks'.
Or we're waiting for availability... meaning 'we have no idea'.

 

[motorboy]

Honda is one manufacturer that does not replace engines-your dealer will take it apart call Honda tell them what they found-if the finding are iffy(meaning their not sure) they will send a rep to take a look-if not the parts will be ordered and the bike fixed-it is not going to be done over night at best two three weeks

 

[8lincoln30]

So the dealer says they’re waiting on parts, and that they’re replacing the cylinder, piston, rings, and oil pump. Does anyone know how long it should take once they get the parts?

Thanks for the update.
How long the repair will take... Will depend entirely on how quickly parts come in and how willing the service manager is to designate a mechanic to stay on your bike until completion.
Play nice and throw out lots of compliments for what they've already done to diagnose the problem. Sounds old-fashioned, but things normally progress better with a pat-on-the-back than a boot-up-the-arse.
Just saying.... "Patience Young Grasshopper".
