    Tatanka,

    Where are you located.....looks like it might actually be Buffalo country.

    A bit of wobble at the CS sprocket is normal.

    However, you should know that the output shafts are NLA from Honda as a spare part. That means taking VERY GOOD CARE of the one you have is important. The Red Cap is probably good insurance even though not exactly cheap.

    Conventional wisdom here is to use official Honda CS sprockets and make certain your chain is adjusted to spec or even on the loose side of the spec. And for you with an extended rear suspension I would go so far as to get the chain adjustment perfect.

    ..put the bike up on a stand so the rear wheel is off the ground.
    ..disconnect the rear suspension linkage so you can move the swingarm up and down
    ..use a tie-down or other strapping to raise the rear wheel so the CS sprocket center, the swingarm pivot center and the rear axle center are all in the same line (a simple string line works for this)
    ..the chain will be at it's tightest point when all 3 centers are aligned
    ..then adjust the rear wheel so the chain slack is removed but can you can still spin the rear wheel without binding.
    ..reconnect everything and re-measure the chain slack with the bike on the side stand.....this is now your personal chain slack measurement. I use a sharpie and write it down on the swingarm so I don't forget.

    Send us a photo of the spines if you'd like other eyes on the area.

    As for the off-idle stumble, I'd start by replacing the pilot jets. The orifice size is so small that even a good ultrasonic carb cleaner will not normally clean these jets well. If your home altitude is not over 3000 ft or so, you might also consider installing #40 pilots rather than the standard #38.

    Carb sync is always a good idea. You'll need the appropriate manometer and a long #2 phillips screwdriver to access the balance screw through the intake tube hole. Be patient....the adjustment is very sensitive and even the weight of the screwdriver on the screw head will alter the balance. Unless the carbs are way off 1/4 turn should be all you need for balancing....normally less.

    Excellent info. Thank you. I’ve read that the CS wobble is fairly normal. I don’t have any of the dreaded rotational slack between the sprocket and CS shaft, so I think I’m ok there. But I agree with precautions. I do run my chain slack to deal with the altered swing arm angles and the increased extension at the linkage... but I haven’t formally checked the tension with the components aligned as you mentioned. Good tip. I’ll do that today.

    Thanks for the info Ray. I hate the thought of you not being a Transalp guy anymore...I still have too much to learn!
    I am in London on the 14th and 15th, and would be happy to bring something back in checked luggage, if someone can find it. I will probably be there in December too.

    I've not heard of Megazip before. Thanks for the tip.

    Their web site does show one crankshaft in stock in the USA warehouse.

    I'll send them an email and find out if they do, in fact, have the part available.

    If so, are you interested? It's yours since you found it first. Let me know.

    I’m in eastern PA. Lots of good farm roads and dirt roads around here. Very hilly. Looking forward to doing some multi day trips with this bike. My background is track and trail riding on a KTM 400/450/500/300 xcw for the past 20 years, so you can imagine how smooth the TA feels on the road, in comparison to my trail bikes.

    Nice area.

    You'll likely find the suspension on the TA a bit disappointing after all the nice WP stuff you're used to.

    Also the TA can become a bit of a handful over multiple large whoops and when trying to turn around on the side of a hill.

    You just go a bit slower and enjoy the scenery.

    Hey Ladder,
    My transalp runs just fine and has got only 38.000 km. on it. I just thought maybe you might be interested. So go ahead. :thumbup

    Edit: I was looking for you, since you said "any old Honda shop somewhere in the world...." I don't need one.

    Took the TA to the Hammer Run National Dual Sport event last weekend. She did me proud. Completed 83 miles of mostly single track. My biggest issue was ground clearance. Everyone enjoyed seeing an old, heavy bike at the event. By enjoyed I mean snickered a little. Anyone can do it on a light bike.

    That site looks sketchy to me, it is just too weird that they have one of every unobtainium part I looked for in their US warehouse.

    There's a guy on the TA FB page I admin who has a 90 he bought from a customer (in pieces) that he is trying to sell off. He is in your general neck of the woods (within 500 miles). He may be worth contacting. If you are on FB, I can PM you the group link

    No FB.

    This is as close as I get to social media

    Thanks for the info.

    Giving Megazip a try. Will report back

    I had to clean my idle jets today. It's been 5 1/2 years since the last carb cleaning. Guess I don't ride enough to keep the gas fresh. Runs like new again. :clap

    It took most of the afternoon. Glad I didn't have to pay a shop.
    Really glad I don't have to do this kind of work for a living anymore. :D

    Finally made some quick disconnects for the blinkers. Not sure how the OEM wires are but the PO had spliced in some different bulb holders.

    MegaZip Update:

    So I ordered a new crankshaft and two carb boots (from the air tube to the carb mouth) from Mega Zip last week. All three of these parts were listed as NLA in all the parts places I could find.

    I very quickly got a confirmation of payment (that I paid through PayPal since I wanted to have some insurance).

    Monday I received an email stating that the carb boots were, in fact, not available anywhere. They apologized, stated they would update their parts database and sent a refund.

    Good so far

    Today I got a "Your Part has Shipped" notification along with a tracking number for Japan Post.

    So it appears that the crankshaft did exist in Japan and is now on its way.

    Will report back on receipt of the part

    But, on the whole, the operation has been excellent.

    i have the same engine on my TA650 with the NT and RD03
    with different ICM and throttle bore (34mm vs 36,5mm vs 32mm)
    mods...
    UNI foam filter (got rid from the K&N),remove the snorkel,remove the catalyst,pilot jet #42
    everything else is stock (needles,main jets #132)
    total gear ratio same as the 600 (15-51 sprockets,the 650 has different primary reduction 1,763 vs 1,888 from TA 600 and RD03)
    highway riding at 140-150 km/h 6lt/100km-39 mpg
    mixed riding 10% city 20% highway with 110-130km/h
    70% twisty backroads with 80 km/h average speed and 130km max speed 5,3-5,5 lt/100km 44-42mpg
    with standard 650 gear ratio (15-48) the same routes...
    highway 5,5lt/100km 42mpg(reving lower)
    mixed riding 5.6-6 lt/100km 42-39mpg(need to downshift more)
    speeds are from GPS device
    my carbs are the same with the 600 so in case you do the swap and keep your carbs the fuel consumption will be close to mine.
    i'm on #45 pilot now,i had to turn the PMS at almost 2,5 turns in the summer (temp over 30c') and 3 in winter with the #42 jet
    for now just testing...
