    Hey guys I’m new to this forum and I just traded a beat up Ford Ranger for a beat up 87 tw200. The guy I got it from said he was riding it about 30 miles everyday to work and it ran great (of course), but one day he was riding it in the rain and it just sputtered out and hasn’t started since...
  4. '09 TW No Power.. Bad Ignition?

    Technical Help
    Hey guys, Rode by Tdub to work yesterday. I took the long way home and rode it how I normally would. After parking it, and taking the key out, I left it sit overnight. I went to fire it up the next morning and nothing happened. First I thought, "Oh great, time for a battery" So I checked the...

  6. How to change spark plug boot?

    Technical Help
    I ordered a new coil, OEM because I didn't want to have to deal with spark plug boots that were the wrong shape or anything like that. Yamaha solves this issue by simply not including a boot. Old wire and boot is on the right, new wire is on the left. How do I swap the boot to the new wire...

  8. 3x CDI's that work on the TW

    Technical Help
    here is info on 3x aftermarket cdi's that work on the tw. none of them are plug-and-play, so you need to frig a bit with wiring. none of the units behave exactly like the stock cdi, which imho is still the preferred option for most applications. waaay cheaper though. the first two units...

  10. Where does this spring go?

    Technical Help
    Hi guys, I took apart my ignition switch to troubleshoot the intermittent power supply issue. While taking the 'cylinder' off the bike a spring popped out and I can't figure out where it is meant to go. I tried it in the position as per the photo, but it didn't feel right. Key was difficult...

    Hey guys, I'm in desperate need of a tw200 CDI. Does anyone have one for sale or know anyone who is selling one? I've tried everything and because of the year it's super hard to find any sort of conversion or parts for this bike. My bike is actually a 96 but I'm located in Canada so I guess...
  12. Ignitech CDI

    Technical Help
    I live in the UK and recently bought a 1991 TW200 that has been imported from the US (only TW 125's were sold over here). It was sold as a non runner project and bought from an importer (online) so buyer beware etc. It looked like it had obvious bits missing lights, clocks etc but nothing that...
  13. Ignition circuit cut-off relay testing - Service Manual ERROR?

    Technical Help
    It appears to me the service manual diagram for testing the 1987 TW200 ignition circuit cut-off relay is incorrect. It is obvious from the ignition circuit diagram that the two wires powering this solenoid are the Brown and Sky Blue wires. These connect to the two lower terminals when the...
  14. WTB: 1987-2000 Ignition, gas cap, helmet lock with matching locks and keys

    TW200 Classifieds
    Hi guys, My 1990 has a gas cap that doesn't lock. I'm not sure how the P.O. damaged that lock cylinder, but I can't seem to fix it. I think that means my only choice left is to just buy a matching set of all three items - the helmet lock, the ignition, and the gas cap from someone parting out...

  18. 1987 TW200 - Absolutely no response to throttle at all

    Technical Help
    Hello guys, About two weeks ago, my 1987 was running fine at about 72-75mph on the highway when it suddenly lost power. I couldn't get it restarted and had to tow it home. I went over everything with a fine tooth comb and couldn't figure out what the problem was. After it sat for a few days...
  19. Cannot re-key gas tank or helmet lock - totally different channels than ignition!

    Technical Help
    Hey everyone, So on my 1987 I have two keys - one for the ignition, one for the gas filler and helmet lock. I'm assuming this means the previous owner, way back in the early nineties, bought a new ignition cylinder. Tonight I went to re-key the cylinders for the gas tank and the helmet lock...
