    I just inherited a 1998 tw from my granddad, it stood still in his garage for a while and I want to get it back on the road again. I'm not a pro at servicing bikes but i really want to fix it myself because of my tiny income and my love for tools. At this moment the battery is dead, the speedo is broken because of a fell and it just wont idle if the choke is off. It only kickstarts when its warmed up, but again with the choke out. The carb is cleaned and a new sparkplug is fitted. The bike had only 2900 km on the clock before the speedo broke and was not ridden since. The bike also idles when I rapidly open and close my throttle when the choke is off but dies when I leave to idle. I don't know where else to look for the problem. Any suggestions?



    Let me know if you need more info?

    I have a 1968 KT120 Suzuki that had the same problem. I had also cleaned the carb several times before and even soaked the carb over night in a gallon bucket of carb cleaner. I was going to get rid of the bike due to it being a pain in the butt. Well one day I had nothing to do I took the carb a part again and noticed the small jet (not main jet) was completely blocked. I don't know how I missed it the first 3 times, but I did. Now this 1968 starts on one kick everytime and I'm going to keep the bike.

    Pilot (idle) jet circuit. Might want to be a little more careful with your carb cleaning. Won't hurt to ride the bike with a dead battery, just fill it with water and kick her to life.

    It might not hurt the bike but it could hurt YOU. A dead battery will suck up the juice and dim your lights at moderate to high speeds decreasing other driver's ability to see you on the road. The bike will not charge the battery back up even if you rode it around for three hours straight. Do the right thing and buy yourself a freshie and a charger (you have to charge new batteries yourself - go with the 2amp model). Alternatively - you could buy the float charger FIRST and see if the battery will take a charge. Fresh DISTILLED water just might do it. Guitar string works great for cleaning the jets out, btw.

    2 amps is way to much charger for TW batteries. 0.5 amp would be better.

    Thanx for the advice. Will take a look this weekend. Maybe I'll get a new battery next week.

    Probably the best battery value is a Chinese YTZ7-S AGM from eBay, $35 shipped. They come filled, are maintenance free, but are a bit smaller than stock so use some coroplast or foam rubber to take up the space.

    I bought a Bosch battery for my Suzuki and it's made in China, the battery on my BMW is a Westco (they are excellent batteries) and made in Vietnam, where their made means nothing really.
