    So I pulled the carbs to check float levels and install #40 idle jets. Putting everything back on I realized that I can't remember what these two brass nipples near the intake of each carb are for. Is there supposed to be a vent tube for these? I don't seem to have any tubes left over so I don't know if I lost something or if they were missing.
    You never can take enough pictures the first time you do a job like this!
    Here is a picture showing the two exposed brass barbs:

    Those are your vent lines here is a close up of what tubes you should be looking for:

    Well, just looked thru my 89 shop manual and can't seem to find it. Suppose to have an emission hose routing diagram behind the left side panel. Try looking there.

    Hmm your picture's not coming through. If it is just a vent hose then I'll replace them. I think they were missing before I started this.
    Thanks for the tip!

    Edit: Well I see your picture now. Thanks again!

    I've seen a few Transalp here with high mounted front fenders. Can you guys provide some detailed pictures or recommendations on how to mount a fender there? Looking at the Transalp front it seems that it's not possible without cheating a bit.

    Sorted it out: on both bikes, the rear tensioners make noise and the rear exhaust valve makes the clicking sound.

    - the tensioner of the rear cylinder makes noise, even though the tension on the chain is adequate and the tensioner locks into place. I cannot understand why...
    I increased the tension by manually pushing the blade down as much as I could, and the noise goes away. This however is not a solution because it overloads the camshaft journals.

    - the rear exhaust valve makes the clicking sound, although it is set to specs (0.1mm for the '88 and 0.2mm for the '91). On the '91 TA, the adjustment screw and the valve have a trace of pitting (that's why it's so loud on the recording). The '88 is fine, no pitting, just a small clicking noise. The rear camshafts of both bikes look OK.

    Turn your motor over slowly. I had a XR motor that ticked, closer to knocked, and couldn't figure it out. The cam chain had a kink (bind) in it and when it left the lower sprocket would stay bent then snap straight. I found the kink when assembling it for the 3rd time looking for the culprit.

    Just a thought

    Just out of curiosity, has anyone attempted/considered swapping out the radiators on a 600 for something smaller? The 600 isn't a highly tuned engine, so overheating in general shouldn't be an issue, plus the 600 should get some cooling benefits from the cooling fins on the engine. I'm coming from a mostly air-cooled background, so all of this is just speculation on my part. It just seems like the current radiators seem like a bit overkill. Or I could be completely wrong.

    I have to agree. From my observations at idle speed my '96 TA runs considerably cooler than my Africa Twin. I'm sure you could get away with a smaller system...providing your climate is not too hot and your not racing in the desert. :D

    Transalps are prone to run pretty hot under certain conditions, reducing the radiators is asking for trouble. Ever sit in slow traffic on a summer day with one? I would make sure your cooling fan and associated sensors are working right before summer gets here.

    The cylinder fines are for looks only, if they help at all it is minor and surely not adequate to aid in much cooling.

    I'm sure your bang on with your comment...but I would think it's all somewhat relevent to the ambient temps and if your keeping it 'moving' or not...obviously.
    Could someone build a one of modified 600v with a smaller cooling system and get away with it....quite possibly? It would have to be a good engine already and not too stressed and tired.

    Well you are right about the ambient temperatures and I doubt
    you have much of a problem being in Canada. Movement is the real key to keeping them cooled off and the fairings and radiator guards sure don't help with letting air pass over the radiators.

    I hooked up a over ride switch so I can turn on the fan before the temp needle climbs to the red zone. Off road these bikes heat up really fast, anybody who was had them off road probably noticed this.

    Here in NC with our 90+ summer days just sitting at a big intersection with long wait times for the light to change is enough for the gauge needle to climb fast.

    If Honda thought they could get away with a smaller cooling system they would have. I think most of us would like to have a fan on the left radiator as well.

    Part of the cooling challenge is that the rear cylinder runs hotter than the front just because it sits behind the front cylinder.

    I agree. Here in the tropics it gets worse when humidity levels rise. I will install a switch to turn it on first. Once The traffic start moving, temp drop fast. I'm also considering a second fan.

    But, reducing the cooling area, it will come back to you sooner or later!

    Thanks for looking, but I found a dealer in Cincinnati that had 3 bolts in stock, so I had them ship all 3. Just buttoned up the TransAlp earlier today with the new bolt and new crushrings; no oil leaks.

    My UPS driver should be dropping off a new HyperPro rear shock and Ricor Intiminators along with some other bits and pieces for my other bikes tomorrow, so it should be another productive day in the garage.

    agreed. that is the reason i added a fan on the L side of the Africa Twin with manual switch. works great at stop lights :deal

    At last fall's Transalp rally in Stecoah, NC, I saw a nice pair of saddlebag racks on Clockwatcher's TA. Big and study enough to serve as a lifting handle if a person were ever to need to, um, pick up his dropped bike. Turns out he had made them himself, and -- good news -- he was willing to accept a custom order for a pair for me. I wanted a set of racks which could be easily converted to carry either a Givi bag or a Pelican bag. No problemo, I was assured.

    He was also sporting a nice-looking a simple muffler which he told me was a moderately modified DRZ400S unit. Sounded nice -- slightly more throaty than a stock TA, but nowhere near an obnoxious politically incorrect thing which would make the neighbors regret you had moved into the neighborhood. Bring him another stock one, and he would make it ready to bolt-on, same time I added the racks. CLockwatcher added that if I hadn't already done the size #40 pilot jet, to do myself a favor.

    Would ya believe a local neighbor rode by to show off his new KTM a week or so later, and when I asked him about the DRZ he used to ride, he said he still had it but had put a pipe and a jet kit on it. Providence was working in my favor. He would be delighted to sell me his stock muffler at a very reasonable price.

    Long story short, I've now done all the above mods, and adjusted the valves and replaced the rear valve cover gasket while I had the carbs off.

    Yesterday I put the lady on the back, and ran a 100-mile loop in the SC/NC/GA corner of the world. The small Givi 21l bags fits nicely and didn't appear to be near as broad-assed as my V-Strom with 37/45l bags appears. The DRZ pipe purred nicely, but my lady didn't notice any change in sound until I quizzed her; then agreed it was just fine. But, the very bestest part of the whole ride was finding some back-and-forth switchback gravel uphill turns (thank you Ms GPS for following "shortest route"). As I negotiated each hairpin, rolling on just enough throttle to maintain stability with a perfect response from the carburetors, I couldn't believe the difference. Whereas before I would have been tempted to shift down to a lower gear to avoid the cough and stumble of a lean engine, now the bike is calm as a cucumber and just crawls up the road like it had an electric motor.

    Like Clockwatcher said to me, "Do yourself a huge favor." #40 pilot jets
