CBR 900 RRV Misfire....

Hi all!!!!

So....after its winter hibernation, I broke my Blade out, for Spring/Summer. It's a 97 (Dec 97!) RRV and I've owned it (second owner) for about 6-7 years. It's not "mint', but its a really tidy, useable Blade.

I got it out in my Workshop and, whilst i left it ticking over and went up to my office, a "friend" of mine walked in and rev'd the nuts off it. I was pissed....but just pushed him off it and went for a quick "rod test" to see how it was after its annual rest!!

At low rev's, it started to misfire and needed a bit more throttle applied to get it going/to get it to pick up. I nursed it back to the shop and it was quite lumpy at idle, but then seemed a bit better.

I thought I should start by checking plugs (replaced about 2 years back with only 1000 miles) and they look decent. I am tempted to change the coils, but at £370 ($500!) for the pair, if I'm not right, its a waste of cash. I also noticed when it was rough at idle, that it almost seemed to "knock" a bit at the bottom...but am not sure.

Any ideas of symptoms when the coils start to degrade? Is it low end misfires? Anyone on here have good used coils i could buy? Found some on eBay in the UK, but they won't guarantee them (like buying any used engine components....sellers claim ridiculous low miles etc!!).

Thoughts on any damage possibly caused by the dick of a friend rev'ing an unloaded engine like he did?

Thanks in advance

Re: CBR 900 RRV Misfire....

Probably just crappy winter petrol. You could try some snake like STP or Seafoam fuel cleaner, or drain it all out and replace.

Coils can be tricky, but they are available on fleabay, etc used. I got a pair last year as I was chasing a dead cylinder, but then decided to eliminate them one go with coil on cap from a 2006 600RR which only cost me about $75 total.

Re: CBR 900 RRV Misfire....

For some reason....my reply didn't seem to post...

Do you reckon the stick coil mod is worthwhile/easy to do? Any thread with instructions and which coils I would need???

In my 99 track thread in my signature I had it well documented, before Photobucket phucked it all up. It was one of the last mods I did, so it’s towards the end. I have all the pics still, and you can read my narrative on them in the thread. It was very easy. I used 2006 600RR could IIRC, but an older sub wire harness as it was a bit longer, but the connectors are the same. I made the harness is a way that it plugs right into the original harness, so I can immediately go back to OEM coils if need be.

It’s maiden voyage with the coil on caps was a track day. Ran without an issue all day.

Re: CBR 900 RRV Misfire....

Awesome.....Ian....how can I get the pics and find your narrative? I think that, whilst I have the poor thing apart, I would like to do this mod. I have nothing to lose and I would love to have it running even better.

Guys...y'all been brill

Re: CBR 900 RRV Misfire....

I'd try fuel first, and drain the carb float bowls (there is a drain screw at the base of each one) just in case of any water ingress, drain the tank as far as poss and slap some fresh fuel in. My RRw (1998) had two sets of leads and caps on in in the time I owned it so that's another cheap fix rather than forking out for coils. The lead and cap and coils are 3 separate things and can each be changed separately, unlike the later Fi models that have the coil as part of the cap, yours will have two coils mounted on the frame somewhere under the airbox, around the head-stock area - follow the leads back from the plugs, 4 HT leads one to each cap (same stuff as car HT leads) and then the cap on top of the plug.

If you get 2nd hand coils they could have a fault too so you still don't know 100% for sure if they are ok.

Re: CBR 900 RRV Misfire....

Awesome guys. Thanks so MUCH Ian....will look into this. Machinehead, I am working tomorrow, but on Friday, will be doing exactly as you say. Start simple and work up. However, love the idea of modding the coils....seems a sound plan?!

Thanks Peeps

Re: CBR 900 RRV Misfire....

I did the Coil on Plug mod on my '98 a number of years ago.... more modern technology better spark discharge, cheaper to replace...

Works for me

(not really standard at all to be honest, but it keeps me amused!!!)
