If your hands are going to sleep I'd look at your seating position and your back/neck. Could be too much weight on your hands, unlikely with a dirt bike, or your neck is causing problems. Or if your hands are cold, wear gloves - j/k
My hands could be numb because maybe I had a death grip on the bars. This thing is a handful compared to my ninja 500 and I am still a fairly new rider. (Less than 3000mi's riding total)

Yeah I am nice and loose on the ninja 500, but not the XR-R. I will get used to it. So far my face hurts too from the grin. Nobody has the sweet cheeks?

Hey - troubleshooting my XR right now....looks like weak (yellow) spark.

Testing my coil .....I have found no references anywhere to resistance for the primary and secondary.... only peak voltage tests, which I can't do.

My primary is showing 4.5 ohms, and my secondary from coil to plug cap is 11,250 ohms. Does this sound right or is this completely wacked?


Also, found a little puddle of water inside my stator cover. Rusted the silver end of one of the ignition coils on the stator - no other visible damage. I sanded the rust off, could there be any other ill effects there? It hasn't changed my problem, still runs like crap. It is not completing a burn and the plug is blackity black black black after just 30 seconds. Carb is clean and valves adjusted.

If its had water inside the cover check there's no rusty flakes between the solder points on the trigger coil.
(Thats what stopped mine - faulty gasket, lots of water and rust!)
Also check the stator gasket is not damaged/allowing ingress of water
Check fit of the rubber grommet on the stator cover, if all else is OK thats the only place water is likely to get in

Hey JM, thanks. The trigger looks ok. The gasket is f'ed, and so is the rubber. I just don't know if the stator gets f'ed if a couple pole ends (one of them the ignition pole) of the stator shows rust. I sanded off the rust, but the running condition hasn't changed. Could there be more problems that I can't see?

So is there a missing bolt on my (new to me) XR-R?

Seems like something should be there...

I am fighting with ignition problems aswell! I just bought all new(used off ebay) ignition components and guess what?! No spark! I tried the stator, nothing. Tried the CDI, nothing. Tried the coil, nothing! All different parts, nothing different. The only thing I have not changed is the wiring harness but I did check it out and it is fine(continuity)



I am just about ready to set this thing on fire!!!


Anyone around Denver want to earn some beer by testing my CDI's on their known-running bike?

Drain opening for water that falls into the spark plug pocket. Keep it open with a toothpick in case mud clogs it up.

My main jet has a brass nut on the holder. It was set to hold the jet from seating completely into the carb body. If I take the nut off, it screws in farther. The bike ran fine in this position, but has anyone seen this before? It's a 170 main, and I've got a 68s pilot, for what it's worth. Oh, and it's clean now.

Jiminy,

"weak spark, orange colour, black sooty plug" - does not sound like a weak spark to me.
Get a normal button, 4 holes, and rig a grounded wire through 1 hole and another wire, which you will connect to the HT of the coil, in the opposite hole. This creates a jump distance of ~8mm, and it should jump this distance easily - try? Take the plug out the head, then kicking becomes a doddle.
But it sounds like yours will do this fine, your carb is the problem - and good lord, I hope you cleaned it well! Shiny parts bru, and use compressed air too to unblock any hole you can find.
That nut on the emulsion tube (the long part) should be there. But check
http://www.dealercostparts.com/pages...BNYMBN4E1700BL
and see for yourself what parts must be there and which one's you have? I think the big tube seats on the needle jet and the nut is just a locker, and if you say that without it it goes in further then maybe the n/jet is absent - which would explain that very sooty plug & shite running?

Your freshly sanded bits now shining you may want to put some grease on, or paint the lot with oil. Would stop rust forming the next time some water makes its way into it, and normally a wee bit of oil does actually.


Jaronimo,

depends what version/type FCR you got. Some have the slide operating system on top making it just too high to fit, and you'd have to heat-up & dent your tank(s). Jetting these things is not too easy either, and a plain pain compared to a TM40. Then, the advantage over the latter is minute if at all, probably only noticeable when you go to the dragstrips with it, so I'd KIS and get a TM.

Yep, what he said above. Back off the nut. Screw the jet all the way in until it stops, then lock it down with the nut.

It sounds like it is something easy.

Spark plug HT lead, spark plug cap, wire on coil ground to earth broken, ground wire in stator broken,
condenser faulty, bad connection in wiring harness etc
