as near as i can find hope it helps

Hi did you fix this problem as i have the same trouble fitted a carb kit still the same so got a new set (second hand) as mine had a broken choke and tick over screw still over flows when running, can anyone tell me or confirm were the two fuel lines go top and bottom fuel line is the top one the vacume pipe?? mine is a 1992 tdm

Hello! I used to own a 1991 XTZ (Off road version of your TDM) And the battery if I remember is behind the right side panel, these are a push fit so be careful when pulling them off. Gently pull towards yourself one edge at a time, If not right side try left. You'll be investigating under your seat too as there should be a tool kit in your tail piece to help remove battery.
Merry Christmas ans remember push the Blue FixYa button!

your starter is stuck on disconnect power and move bike back and forth in a gear this should unstuck the starter or light taps with wooden handle of small hammer then reconnect battery after you make sure it is charged low battery will cause this issue

The tdm is a dry sump engine where the oil is in a tank under the seat and is pumped around the engine and returned to the tank by a scavenger pump in the bottom of the engine so a level window on the engine is not required

running too lean. try rejetting.

no not wiring harness! Unless the stator connector is unplugged. check to make sure the charging fuse is not blown. Should be a 20A or 30A fuse. When the bike is running test the battery to see if it is charging, should be between 13.25 volts and 14.5 volts.

Hi,the voltage at the battery with engine running should be around 13.8 volts.There could be any number of reasons as to what the problem is.Check the battery connections, they may be loose or corroded both on the battery and in the case of the earth or negative connection,check the frame connection.

dont try to crank it the carbs float are stuck and will fill crank case with gas drain the oil turn the gas off tap the carbs with a small object then turn the gas back on try cranking it then

I would never think a bike was smart enough to shut down unneeded accessories like that but then again I haven't been around many newer ones much. I would just charge it ride it and see if it happens again. if you get done riding and the battery reads low again that should answer your question

Because of the higher voltages run in bikes nowdays to meet fuel regulations,spark plugs are often a big problem.Drop a new set of plugs in .It's the easiest and cheapest place to start.No dealers to rip you off.If this is not the problem,it would suprise me.Hope this helps

check chain tension and that the aft sprocket lines up directly with the front first, if its not that then take the front cover off the countershaft main gear drive and check for play maybe a bearing is worn out..

There is no easy fix, you need to remove the complete cover and clean it from the inside with a pipe cleaner or similar.
You can usually reuse the gasket.
If you rest the bike on its side you can leave the oil in, and it doesnt mess up the workshop floor.

first remove seat then remove tank, unbolt the 2 nuts holding the fuel pump on then disconnect wiring and then wiring from battery remove 2 bolts holding in battery box and remove through whole where fuel pump was (take care with battery wiring).
