    Hi all. This is my first post on this forum. I've had a 2005 TW200 for a few years now and it's been a pleasure to ride. It was running fine until recently. I took it in to a local mechanic who pulled the carb apart and replaced bad O rings and it ran fine for a few months. It started...

  7. 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...

    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...
