1992 Yamaha TDM 850 cam chain tensioner location

SOURCE: timing chain tensioner adjustment

all v twin engines are noisy, if you could totally silence the exhaust noise, you would be horrified how awful the motor sounds, it could probably do with the cam chain tensioner ADJUSTING. i wouldn't think it would need replacing. unfortunately the manual only recomends this being done by a qualified tech, i have a xvs 650 with same trouble. i would adjust myself if i could find out the correct tollerences.

Carbs must be cleaned very well, adjust the vacuum level, the air mixture screws with a gas analyzer and the TPS (if there is one but I think not).Also recheck the valves clearances.Fuel pump ok I suppose.

SOURCE: battery replace tdm 850 yamaha

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).

SOURCE: where is the battery in a yamaha 850 tdm located

I must first say i havent done a battery change on a T.D.M. 96-97 for a very long time. I probably try and avoid it like the plauge there a pain in the ****.
First lift the tank up and clamp the two fuel pipes leading to the petrol **** or switch. Take the pipes off at the petcock fuel valve or switch and remove the tank.Then unbolt the diaphram type fuel pump and move to one side. Undo battery live cable from starter relay and wrap with insulation so as not to short to the any metal part .Now unbolt the ground on the frame and pull both through to use as a means to remove the battery. Now look under the sub frame , between the shocker and the frame is the battery box.It will have two 10mm bolts holding the battery box in place and a plastic dowl at the bottom. Unbolt the two 10mm,s lift battery box off dowl and tilt the bottom towards the shocker then pull the battery out by the two leads.To rebuild reverse the procedure dont forget to put the leads back on the new battery before refitting. Also the two 10mm,s can be a bit of a problem if they are seized so take your time and try not to snap them
