    I suppose the tanks have a vent tube because they did not want to make two different tanks.
    I do wonder if the California cap is different though, and not vented.
    None of my other bikes have had gas tank vent hoses.


    I can see not wanting to trash a $600.00+ silencer!
    Bike runs great with less back pressure, the FI system seems to compensate fine, no surging, no backfires on over run, adding fuel with the power commander did not do anything that I could tell, although adding 2 degrees of ignition advance at 5000 rpm and up gave a nice boost in power (with no knock).
    The SMART thing to do would be to fit a quality aftermarket silencer or entire exhaust system.
    I tried a few Emgo silencers that really hosed up the way the bike ran, no power above 5000 rpm at all, and way too loud.
    I will buy a new stock silencer if I have to, rather then dealing with junk.

    The tires did not seem to make any difference in handling that I could tell.
    The bike still seems very nimble, but lean angle has increased a lot with the fork springs and taller tires.
    I will not push grip limits on the street, its just not worth it.
    So I want a longer lasting tire that works well, and the cheap Shinko's fit the bill. They are not hard like tires in the old days, they seem to grip well.
    On the track, maybe Avon's?

    Anybody use a Sportster muffler on their SR? Flows well, not loud, and can be had cheap.

    I think someone did.
    Seems like a good idea...

    I think it was tedbmw, but he changed it to something else(currently) , if it was him I remember reading that he welded a reducer or adapter to a stock Harley slip on ,

    I looked at some on ebay, the mounts are all over the place, you want something that you can bolt to a support.

    You should be able to go behind the Harley dealers and raid the dumpster and get a bunch for free....

    Got a nice ride in today, the weather was very nice.
    [​IMG]

    Ended up in the Smithville New Gretna area for about 100 miles.
    New Gretna has some very old and interesting houses in the area, and this lake/park with a swimming beach.

    Had the bike up to 95 mph on the short bit of parkway I had to get on with a state police car having someone pulled over on the other side that I missed seeing.
    It was ok since he was busy and on the other side of the road....
    Fantastic bike. 19,880 miles on it now.

    Well I've gotten in a number of nice rides these past weeks, now nearing 21K and the bike is still a total hoot!
    Hadn't ridden the DL for nearly 3 weeks until recently and damn, that thing seemed Huge after so many miles on the SR the previous three or so weeks!

    Today I did around 150 miles, weather was perfect of a bare bones machine mid 70's to high 80's but low humidity. Saw 5 nice vintage machines, a mint 70's BMW R90S in Daytona fucking Orange smoke and followed along behind some small displacement single. Couldn't tell what make but it had vintage tags and judging by the speed he maintained (45~50, even going up hill) must have been bigger than a 125 but no more than 200. I know my 75 CB 125 can't maintain 50 up hill on a twisty but can cruise at 50 on the flat, so....
    Also saw this, a Yamaha single, drum brake but no kicker (could see a plug where it would go), carbed, so its got to be fairly old (80's~mid 90's maybe ?)

    Not quite sure what this is, anyone have an idea?
    Also went by a small vintage car meet and saw a primo red&white '57 Corvette driven by an older lady but she seemed to be able handle it quite well. So many times I see cars like this being driven at 10MPH by some old fart who seems almost afraid of it could do in the right hands!

    Also been playing with my new upgrade to my Olympus Pen Micro-4/3rds, traded in my old Pen E-P3 and E-P1 and some lenses for a Pen E-P5 which is a Huge improvement in features and layout of controls, plus a few more pixels. ordered a new lens 60mm F2.8 and just got a nice 25mm prime F1.7, sweet!
    here are few pics with the new lens

    nothing beats a prime lens for sharpness, should have taken a tripod, close-ups hand held are problematic esp, with the onset of Parkinson's, some days are better than others... *sigh*
    still can't wait wait for 60mm marco to come in.

    Once I get all the pictures I've taken on my (almost) daily rides processed and sorted out from the last two months of riding I'll post up a few here with a link to rest on my web site's gallery.

    I just used the hardware that came with it, put some old inner tube inside the clamps that go on the grab rail to prevent marring the chrome and its held nicely.
    I have found the side racks that I got from him are more useful for carrying a load using soft saddle bags that just throw over the seat, gives you something to tie them to plus keeps them from rubbing the tire or flapping around.

    I also run the Shinko one over size front and rear and have to say I really like them. Can't say they feel any stiffer than the ones that came on the bike and the rubber seems to have good grip, I've hit a few washouts in hard corners and the bike stayed planted. Running one over size tires did "slightly" affect the responsiveness but going a few pounds over recommended (the pressure as stated on the bike's sticker) corrected that. It now corners as quick as before. I figure the bike has enough "built in" flex due to the twin shock, tubular frame design; no need to add to it with really soft sidewall tires! The design is inherently "flexy" as are/were all bikes with this geometry, but I just see it as part of the fun, when the rear gets squirrelly in hard turn, esp. when hitting a bump or hole! but no need to add to it! :-)
    Funny but I go thru more rear tires on this bike than anything I've owned and considering it making less horses (by more than half) I only get 5, "maybe" 6k on the rear. but then I'm rarely running below 5K and doing 10~15 over posted, sometimes 20 if I know I have clear road with no driveways or farm entrances and most roads I ride are pretty much all curves/twisties.
    I've even gone with Shinko's on my DL as well, good tires and great price point.

    Just my two cents ..

    No hardware was included with mine :hmmmmm. I tore the box inside out and couldn't find anything. No big deal, a quick run to the hardware store had me squared away.

    I was given a rear Dunlop 404 for free in 120/90 that I'll be spooning on for a trip next month. I plan to add a Shinko 712 to the front due to the good reviews some of you have provided.

    My stock BT45 rear only has 2800 miles on it and it is at the wear bars. I've never had a bike this small wear out a rear tire so damn fast!

    That Yamaha looks like an old XT250 motor with electric start added.
    Must be a fun bike. Nice seat! It just needs lower bars and some chain lube.

    I think I get a bit more life out of my Shinko tires.
    The flywheel on the SR is heavy and shifting fast spins the rear tire a little at times, likely adds to tire wear...
    I also tend to ride the SR hard and fast.
    My bike pulls 5th gear at 3000 rpm quite well, even with the bigger tires and front sprocket, but its a real hoot at 5000 rpm and up.
    I like the Shinko tires and don't understand the idea of them being stiff or hard.
    That comes down to the air pressure, and they seem to like higher then stock pressures.
    I don't ride hard enough on the street to push their grip limits, but found, on the TU250 I used to own, I found them to be fantastic in the rain, which I would not have expected for such little tread.
    I have run about 5 sets and have not had a bad one yet.
    I also ran the BT45 tires and they seemed to wear much faster.
    Maybe they had more grip but I never used it.
    My old cb650 has a Dunlop K81 on the back, that is a hard slippery tire, just like the old days.

    SR 250 or 185. I had one for a while, wish I hadn't sold it. The chopper bars were awful but I put some old mountain bike bars on it and it worked rather well.

    Looks good, I wonder what the suspension travel was.
    Turn it into a scrambler with dual sport tires....
    The old XT250's had pumper carbs stock, maybe fit one of those.
    Looks like a lot of fun for very little money, simple and easy to work on and service.

    My front Shinko 712 came in the mail today and HOLY COW this thing looks huge compared to the factory front tire :eekers. I know several of you are currently using it and say it works great but I wasn't expecting it to look the size of my rear tire.
    IMG_3437.JPG

    I'm pairing the 712 front with a Dunlop 404 rear tire I was given for free in 120/90. I'm hoping that combo works well for touring duty. Looks like the front will help correct my speedo error and the taller rear will raise my gearing just a hair.

    The 712 tread pattern looks fairly similar to the Michelin pilot activ pattern. I used those on my old Bonnie and they worked great.

    Nice! I think the bike looks even better and more proportional with those larger tires.

    It probably handles a little "slower" but is it as stable or more on the highway at speed? How about cornering clearance Brett, any improvement? I've noticed that this thing scrapes pegs pretty quickly.

    I was always scraping the exhaust on the right.
    The tires and fork springs prevented that mostly, maybe twice in the last 18,000 miles have I scraped anything.
    I was grinding the exhaust clamp bolt down half way before the upgrades.
    I did not really notice any changes in handling, the bike was always nimble yet stable at all speeds and still is.

    Stock, the fork springs were really soft, but the back shocks seem very good to me...
    I think the bike rides very nice.
