First Tdm, And A Few Questions
#1
Posted 15 July 2019 - 08:13 pm
1. Bike is very snatchy low down, the wire has been removed for the airbox mod by previous owner, is this normal.
2. I've ordered a replacement cam chain tensioner as I hear slight ticking noise at idle. I've looked at fitting this myself by following instructions for finding tdc but never have i done any work on a bike. It seems a quick job ha. How much do you think it would cost labour wise for garage.
The bike has covered 32000 miles with service history.
Any other tips or areas to look at
Cheers

I expect they will charge an hours labour, but a savvy mechanic should have it done rather sharpish..

Hi mate. TDM900s are notorious for being 'snatchy' low down, which is a shame as otherwise they're an amazing all rounder. If the air box mod has already been done then (apart from drastic action like sending away the ECU for remapping) about you're only recourse is making sure the drive chain is adjusted bang on. Also careful riding technique at low revs eventually gives results but the snatch never quite goes away (IMHO).
Another 'biggy' is the rear suspension linkage which must be kept well lubed. It's a a bit of a fiddly job - especially if you don't have a centre stand - but once done and kept on top of should allow you to sleep at night. Full details with piccies on how to do the job can be found on this site.
I've had two 900s and apart from the above they've proved great bikes which will match other bikes costing twice as much.
One last MAJOR problem is this: when the time eventually comes to replace it what on earth do you buy?

Worth checking the freeplay on the throttle as this can make for a snatchy ride if it's out of spec.
Swapping out the tensioner can be very tricky. Some have had success whilst others have ended up with the chain jumping a tooth or two. Best way to be sure everything is correct is to remove the rocker cover so you can visually check the valve timing before and after you've installed the tensioner. It also allows you to tiewrap the camchain and sprockets so the chain doesn't jump when you release the old tensioner.

There is also changing the CO settings via the dash buttons.
Documented on this site and on JBX's
https://www.tdm-yama...t.org/?page=ISS
which lists common faults.
If the airbox electrical wire has been disconnected then there may have been other mods made - including the CO settings. Unfortunately, there appear to be no standard or default settings to work from. Can you ask the previous owner?
2004 is a very good year

Just purchased my 2004 Tdm 900 loving the bike it's my first twin!
1. Bike is very snatchy low down, the wire has been removed for the airbox mod by previous owner, is this normal.
Fitting a Power Commander completely cured the snatchynes (is that a word?) on my 2010 9'er. No airbox mod has been done.

Another issue which is probably making it worse is one of the chain adjustment bolts has sheared off! It's in the garage on Thursday to get it sorted but currently the chain is a but slack so maybe it will perform better once sorted.

Thanks for all the replies, I have been controlling the snatch with clutch, maybe it's just something I have to get used too!

Common problem with the chain adjustment bolts. Lots of people on here have fitted brass ones courtesy of Lee Henty (on here). They don't seize up quite so easily. Where are you based, by the way. Ali

TDM4ever.
I've thought about P.c But quite expensive, does it have to be specific to the bike? Also I've seen booster plugs on ebay specific for the tdm which claim to soften the throttle response, 129 notes

I have completely junked the airbox flap gubbins, plugged the manifold suction line, disconnected the electric circuit and changed the CO settings.
Now no snatch.
Its not something you have to get used to.

Don't forget chain tension is 50-60mm on a TDM so maybe not as slack as you thought?

Hi there. I feel your pain. Wouldn't bother with the "Booster Plug" - waste of money. And please don't ask me how I know.
Depending what your previous bikes were/are - you may have to learn how to ride the TDM. It is a great bike, but you won't think so if you do a lot of town work.
Last weekend I did 800 miles on A and B roads and some lanes and enjoyed every minute. (weekend = Fri Sat Sun & Mon)
Hombre - can you enlighten me on the plugging of the manifold suction line.

It's all slow stuff really where I'm having to adapt.
At the minute lots of town riding, but soon I'll be using it to commute weekly about 180 miles each way.

There is a tube from manifold to flap actuator. Manifold low pressure provides the motive power for the actuator. When you junk the actuator it is necessary to blank/plug the suction line.

Next job, swap out camchain tensioner! I'm not very mechanically minded, lucky enough the guy I go to is decent, said would cost 30 quid to fit! I'll take that.
