Title: Number 2 Cylinder Misfire
Post by: fishnbiker on January 12, 2025, 11:57:58 PM
My old '95 FELIX is undergoing a ground up repaint & cleanup. After doing a test run I found that the #2 fires intermittently. New plugs, new leads & new coils have not made a difference. With rebuilt carbs & a second rebuilt set used always finding the same problem. Sometime ago I read on a 885 Steamers Facebook thread alluded to a loose connection in the CDI to wiring loom connector (sounds logical). The #2 header pipe stays cool after startup, while #1 & #3 get hot. Not remembering which wire might be faulty is why I'm asking if anyone here has any insight?

Thanks,
Ken/Fishnbiker

I know they are discrete component systems, so should be repairable. I did take some pics of the board on my old one..
If the bike is your long term keeper, a spare ecu is probably not a bad idea. Most 3 cylinder bikes of that era will share an almost identical ecu, wityh only minor differences in rev limit and suchlike, but might be a quick way to check. There are at least 2 on eBay uk for less than £100gbp and I think they are both 1290061's which are compatible with the tiger.
I seem to recal the driver transistor for the cylinder failed on somebodys a long time ago...
I'll see if I still have the pics, they may be on the forum...

Cheers, will look into those suggestions. My thoughts were toward a loose wire in the loom connector (from what I remember).

How annoying. I'll be very interested to see who the culprit is.
Good luck.

Update ... After fiddling around in an overstuffed garage, I finally broke down & bought another CDI, 1998 Tiger model, along with the matching wiring loom to play with testing old vs. newer parts. A two thumbs up to Maxence Sonilhac (TRIMAX) at FACEBOOK on the Triumph Tiger 885 Steamer Owners Group for providing the parts.

But, as often happens, it seems like life gets in the way. My aforementioned overstuffed garage is now a processing shop  for fence building. Sanding & painting 9 sections of 8' panels & posts with 2 coats of oils stain has been my social life for a few weeks now. :^_^

Hopefully back on track in another 2 weeks.

The power transistor could fail and cause these issues, really easy to open up the cdi and have a look, should look leaked and brownish, had a couple of cdi issues as well, tried tinkering with it but only a replacement fixed my problem, issues described in "steamer with bad habits" topic.
Good luck and keep us posted!
