    I think the high yesterday was in the low 50's. It was in the 40's when I got home. I have pretty decent gear. As long as I can keep the wind off, I'll keep riding, unless it's icy or snowing. I keep thinking about a heated vest, but so far I've gotten by without one.

    I am going to try to take it easy this tank. I checked the tires they were what the sticker says it should be but I added a couple psi to it. I need to check the spark plug and valves since I just rolled over 3000.

    QFT. I can pretty much nail all my variations in MPG every time it happens.

    Something that came to mind is yes the valves need adjusting and that could be a bit of a reason why your mpg might be a bit low. But also what kind of oil are you guys running? I run Castrol 4t Full Synthetic, its in a gold bottle. Maybe those running conventional are a bit lower mpg or even from over filling could probably cause that a bit?

    Of course putting more miles on the bike to help loosen things up will always help :D

    I got some yamalube because it came in a gallon jug when I flush this out ill get some synthetic. Also how many miles you guys go on oil change? I did my first at 600 then at 3000 if I remember right the book says to do it every 4000 miles but that just seems like to many on 1.6 quarts.

    I think I will just change mine every 3,000 thats what the manual says and I really have like the performance of Castrol in all my cars, dirt bike. I just make sure the oil is at the right level every now and then, you never know so that sight glass comes in handy a lot.

    I check mine when I get gas most of the time. I have been kinda paranoid since I read on here About the drain plug falling out. I kinda find it hard to hold the bike level while looking through the glass though since even a couple degrees outside of 90 throughs it off.

    i place a small level on the top of my back seat and use that to get an idea of when the bike is level. makes thigns easier.

    I expect to have the TU a long time, and I do abuse it, so it gets good oil and changed between 1000 and 1500 miles. Filter every 3rd time.
    There is not much else to spend money on with the TU.
    And when I put the salvage motor in my bike, I found the oil was very dirty, with sludge in the sump, and even after new oil, the oil looked dirty right away, so I will change it even before 1000 miles to get the crud out.
    The salvage bike came with 7000 miles on it, and I think it might have got the first service and nothing else as the valves were also off, but it does run like a top anyway.

    Hey Brett I know you have probably mentioned it before but what type of oil do you use in your bikes? Any brand seem to work really good for you over the years? Just wondering maybe the oil for bikes are different in terms of who is good compared to the cars?

    It depends on the bike, but in something like the TU the Mobil 1 synthetic motorcycle oil, or one of the diesel oils.
    The diesel oils are mostly 15w40 I think so are summer oils, the t6 5w40 makes the clutch grabby.

    On a budget, the valvoline bike oil seems good, and in the old Triumphs which did not have oil filters, I used to run the not street legal racing oil (Valvoline) which had additives that ruin catalytic converters, and plenty of it.
    It also had no detergents, and I had very little or no engine wear using it.
    The primary and clutch used different oil from the engine, so i do not know how it would work in something like the TU.

    I used to like castrol till I read reports they took all the good stuff out, and an engine builder told me they would not advise running it as it would ruin their cams.

    Good to know Brett, as always your experience and knowledge is always appreciated!!

    I have been looking into tires lately and am thinking I will be taking some motorcycle camping/mini touring trips on the little TU this year yet. I was wondering if anyone has fitted the TU with some "vintage" style tires or something that look more classic. If so what ones have you put on? The "vintage" tires Im looking at are around 55-75 dollars each which I thought was very reasonable. I think with the new tires I might even go for the scrambler or grass tracker look I had in mind and would be able to make the switch by putting the stock shocks back on and making a new seat. Im telling you this bike is just like a motorcycle used to be, take it anywhere do anything on it type of bike. Although I have yet to test it on a real dirt road ha. But it sure would be fun I think

    Both tires look ok.
    I used to run the K70's on my Daytona, and they do very well on the street and in the dirt.

    They are tall soft tires so give a good ride, they grip well, they wear faster then some other tires, but they grip very well. Forget about riding with a flat back tire, the rear size I had on the Daytona was tall and soft, so with a flat it just flops around.
    I had a tube pinch in the rear running the shinko's, and rode it home 10 miles, without even damaging the tire.

    The TU does great on dirt roads, just don't fall, or hit any bumps, as the shifter and brake pedal will snap off/bend up, the foot pegs will bend down, the forks will bottom out badly, the headlight will break ($$$), the clutch and brake levers snap off, gas tank will get dented, etc.
    That is a shame, as the light weight and the motor are very nice in the dirt.

    I put some shinko dual sport tires on my bike and dirt rode it a bit, and it was pure terror of falling and busting everything up, the ride was nasty due to the forks and little front wheel, and just trying to loft the front wheel over a bump bent the pegs down at 45 degrees....

    Isn't that what "dirt bikes" used to be though Brett? All the old Enduros where just street bikes with a more dirt oriented tire and maybe a bit more suspension?

    Something like this more for around the campsite type roads to go exploring on?

    Great video! I had seen the Hammarhead Jack Pine before, but not the video.

    Funny, because I was actually laying awake last night thinking about ways to convert the TU into and old school dirt/street bike. Not because its the new hip trend, but bc it's the best of both worlds...

    I think they did a lot of work to that bike to be able to ride it like that.
    I had the new Bonneville and no way I would dirt ride it on anything else but hard smooth dirt roads, which is mostly what is in the video.

    I have had a number of dual sports and old bikes over the years, and yes, many of the older bikes did quite well in the dirt, even a stock cb350 was fun and quite tough.

    The weight of the TU is good, the motor is great for the dirt, but everything else sucks.
    The back shocks I can live with, but the forks just won't do.
    You only have 3 inches of travel, they waste over an inch in the full compression bump stop which is really just a hydrolock setup where the damping goes WAY up and stops the forks from bottoming.
    If you drain the oil out, you could get over 4 inches...
    I have looked into making it softer so you could use some of the travel, but have not tried it yet.

    The old bikes had little headlights and wide bars that prevented damage, they had the controls tucked in better, and with old Triumphs, had rigid mounted pegs that did not fold. I crashed my old Daytona way too many times and never broke anything (on the bike).

    You would at least have to do something with the TU foot pegs, just a little air and they bend down.

    One minor fall and you would likely rip off the brake pedal or shifter, break the levers and/or their mounts, bust the $400.00 headlight, dent the wide $600.00 gas tank, and bust a turn signal or two.

    In rougher stuff, the 18 inch front wheel and the 3 inches of fork travel make for a very nasty ride.

    Its just not worth it to do all that would be needed to make things good, and it would ruin the great street performance of the TU.

    I am looking for something vintage that would be fun as a dual sport.
    I have a list of bikes that might do better then the TU, all are old and some are very old.
    Any old 350 to 500cc single or twin that is not super heavy is in the running.

    At the top of the list is a late model sl350 I think.
    If I was set up to weld, it might open up lots of other bikes, gn400, cb350, s40 savage, sr500, Honda 500 Ascot, sx650, even an old solid frame chain drive 883 sportster.

    There is this CB400SS, 400cc single cylinder air cooled engine, 27 hp which just landed - used from Japan. I am drooling...

    Thinking about making look like this one, or keep it as is

    This has been around for a while, but we are unable to get it in the US.
    Great style, enough power, I bet its very light, but it is an old design and might vibrate quite a bit, as I do not think it has a balance gizmo setup like the TU has.

    I like the fast red one:

    http://ja.wikipedia.org/wiki/ファイル:Honda_CB400SS_Special_Edition_2007TMS.jpg

    Its got a tach and a kick starter!

    The spec's are 19 inch front wheel, 18 inch rear, 29 hp stock, 306 pounds dry.
    If it does not vibrate like a paint shaker, it would be just what I am looking for...

    Not vintage, but by the time you get something vintage running properly it will outprice the Honda. FI, light weight, truly made for the dirt, 250cc, liquid-cooled - what's not to like? You could always replace the rectangular headlight/number plate with a round headlight.:wink:
