The weather couldnt have been better & really keep the tracks very grippy & virtually dust free - perfect !
Riding lead I had a quite a variety of local fauna running out in front of me including numerous roos, a herd of goats, lots of sheep, an emu & a kamakazi magpie, luckily I didnt hit any.. .

Our first real 300km ride for over 3 months was enjoyed last weekend for the ol' rebuilt Bee-arch & me and we had a ball. Risk taking was out of the question as the thumb is still healing ..... and the bike was still so shiny ...... riding sweep was the order of the day & I must say it was actually a pleasure not having to be so alert for the usual animal terrorists.

Here are some pics of the country-side we have at our doorstep if you are interested, none of the TDM though.

So Mr Masterbrewer, you will no longer be subscribing to the old Aussie saying "well, stick mne thumb up a kangaroo's bum?"

Well done on the rebuild and you beat me to it again - although there is nothing wrong with my perfect TDM, it's the rider who is shyte.

Actually I think that's what caused my injury as I went down

Hay your going again..

Ive got a question for you guys...

My 93 TDM is still "new to me." Ive noticed than when the bike is idling every few seconds there will be a stutter in the idle and i'll hear a little "thump" from the engine. it does it in perfect rhythm when it starts.

thump---10 seconds --- thump --- 10 seconds --- thump...

Any ideas or is that normal?

Not normal. Does it do it if you increase the idle speed slightly (around 1500rpm)?

Have you done the electric fuel pump conversion yet?

Nope - its perfectly smooth anywhere but idle. It doesnt do it all the time. Its most prominent when the bike is cold but it will do it when its warmed up.

Havent done it yet. Ive never had the 'starving for fuel' feeling at higher rpm so it hasnt been a concern.

That is one cylinder missing/cutting out at idle when cold. Mine did it too until I cleaned the carbs, dirty pilot jets will cause that. If it runs fine after warmed up it's not really something to be overly concerned about. Until they get dirty enough for it to cut out on both cylinders, which on a twin = not running.

Thats kinda what i was thinking, i just couldnt figure out why one would cut out in such a regular rhythm. Dirty/clogged carb makes sense because the bike sat for a LONG time before i bought it.

Mine does it too. If I keep the choke out a bit until warm I don't hear it.

I think it's predetination due to lean idle mixture.

Suggest richening the pilot jet 1/4 turn to see if that eliminates the problem.

Good luck.

...errr .......... probably good idea to clean the carby jets too if it's been standing around that long.

I just put my '93 for sale in flea market.

Had the same issue with mine for a bit. After the previous cleaning it seemed to go away, it almost sounded/felt like the engine was choking for air. Seems fins now though, I would just suggest a really good carb cleaning before you start playing with adjustments.

When you guys say clean to carb do you mean a full tear down or running something like seafoam through the tank?
