My 99 RMX250 lost spark out of the blue a few weeks ago. I thought I would start a new thread here. It was mickv who put me onto this so all credit goes to him thanks mate! :grinning-

At first it appeared my problem lay with the cylindrical lighting coil bolted to the upper triple clamp as disconnecting it seemed to sometimes give me spark back. Turned out to be coincidence.

The problem was the pink plug behind the headlight. It has a bridging cap and once I removed it 6 pins were badly corroded and full of mud. :o
I cleaned and bent the terminals slightly so they had a tighter hold and it runs perfectly again. My advice is check and clean yours now before you have problems. :)

This is the plug we're talking about.

Good to hear that it was resolved easily. Some have actually cut the plug off completely and soldered the wires together. I just clean it from time to time, and use some silicon o-ring grease.

Yeah thanks a million mate. I was tearing my hair out trying to work out what was wrong. I was at the point of sending parts away to be tested. I'll keep an eye on it regularly from now on. I've also sealed the entire wiring behind the headlight in a plastic bag so hopefully that will help too. :cheers

Thanks for the tip ^rockon

Yeah it's a simple one Tony but can cause so much grief. Give yours a quick check before next ride just to be sure. Especially if you've ever drowned your bike, or pressure washed it or ridden it in the rain.. :laughing-

Maybe! I'm still mighty tempted by a WR300. ^ton I'll probably still keep the RMX though it's a great bike for what I do.

Glad to hear your sorted, the lighting coil you were on about is, unless yours is different to mine, a capacitor, it gives the coil a massive boost in dc power on starting when cranking speed so low...

with the plastic bag keep an eye on it as they are great at not only keeping water out but just as good at keeping it in they tend to sweat when left standing and all kinds of nasty things start happening ( 13 years as an auto electrician i have seen a lot of this ) bags are great to put over conections for a wet ride or washing but i would recomend removing them straight after to allow any trapped moisture to escape

Yeah I'll keep an eye on it. I was thinking that could be a problem. I might take it off after washing the bike each ride. :)

Hi Guys
Noticed you have RMX250, I bought ona 1999 model just over a year ago and have rebuilt most of it with RM250 parts, seat, sub frame, black plastics, carbie, aftermarket headlight, just did top end. I want to put a FMF Gnarly exhaust on it. Does anone know what the part number is or what model RM250 pipe will fit, as I have ordered all of my parts from the states and saved a bundle.
Thanks

No pipes made to suit US model RMXs will fit 98 or 99 Australian models. I have a 99 RM250 FMF fatty on my bike. The only difference is the header is a slightly different angle on the RM. I just cold bent mine and it fits perfectly.

I believe the 95 rm is the same but it does need a couple of small mods to make it fit as the 98+ has the 96 rm frame.

Sounds awesome, show us some pics!

I just spent a few hours cleaning the rust and paint of my beaten up exhaust and would love to get my hands on an after-market one. Can you let me know which year RM plastics etc that you bought to fit?

According to this website http://www.suzukicycles.org/RM-RMX-series/index.html?RM250-RMX250.shtml~isoraami

My RMX250 (10/1998 compliance = 99 model?) looks pretty much exactly like this 1998 RM250

I bought 96-98 plastics UFO front and rear gaurd from MX south, along with a monster universal sticker kit, fork cap, thin head gasket RM seat mount for the tank. I needed this as I bought a good as new RM full gripper seet and sub frame for $50 on ebay US plus $50 delivery. Polisport RMX headlight. Bought a new piston, rings and bearing for $100 from ebay US.
I wanted to buy a black tank and radiator shrouds but the bdget didnt allow, wanted to keep the bike reasonable cheap as I have trouble holding on sometimes.

I wanted to put a monster sticker kit on it from the UK, spiral gfx have a getto kit they will do for any bike, but again the costs prevented it

Most of the gear I bought was almost half of the price conpared to buying in Australia, if buying new just put a big order together to help with the shipping costs.
I would love to put a pitchure on, but I am new to the site and I dont know how to.
