    Hey I am in Maryland and the riding season is 365 days, Some of those days are just more exciting than others. I'd say ICE is the only thing that keeps me off the bike! At least in colder weather you don't mind wearing all that extra protective clothing!

    It used to get like that in El Paso, TX. I don't like riding in that kind of heat.

    Carl,

    The HP figure came from the owner I believe. It was a few years ago I think when he told me. I was looking for another bike and he owns a dealership, he was trying to get me to buy an 800cc bike and I said something about not enough power for a sidecar +. I'm probably wrong on the model, but the point I was trying to make ( I think ) was how much was done so long ago with relatively much less power than today. In any case it was impressive seeing that bike/sidecar and 3 people on it.


    Beemer Nut? bah the only Beemers worth owning would be the R1200 GS or the F650 GS

    I was headed for Cincinnati Ohio once, there was a drizzling rain, nothing I couldn't handle, suddenly it turned to hail and it felt like some one shot me in the face. I know what you mean about the rough weather, any more I prefer the sunny days also, except in Phoenix. Too hot there to ride during the day in the summer. The faster you go the hotter it is. Like standing in front of a heat gun.

    I must be lucky and not know it, the ride season is a lot longer here in sunny California vs Pennsylvania. I get a kick out of American Chopper when it's snowing on a test ride. A few years ago I took a trip to Canada and got caught in a snow storm, not much fun and too cold. I rather watch snow on TV. Two wheel drifting will hone your reflexes. With 9 scooters some days I want to thump the 600cc Matchless single, the back roads on 750 Triumph, do the twisties on the 850 Norton's or a little highway time on the Beemers. Decisions decisions.

    I've definitely done my share of fixing my bike across the country. I don't regret it one bit, some of the best people I've met and some of the best times I've had came as a result of being broke down in the middle of nowhere.
    I also don't care what some one else rides, if you like riding, ride what you like, or can afford.
    Its funny though, when it comes to the "if you don't ride ---- you're not ---" attitude, I've seen it most out of the Goldwingers, believe it or not.

    Testing for reactions. Usually I get the single finger salute within the 50 mile radius of home by beep beeping a broken down Harley, even if they ride home in a pickup bed.
    On the open road and at rest stops Harley owners are nice polite people that also like to ride. Fun to guess at how people act against different brands of scooters, to me I just enjoy the ride.

    What fun is that ?

    The new bigger 750cc R75/5 came out in 1970 with 50 hp and 43 ft/lbs tq with
    4 speeds until the 1975 R75/6 series began with the 5 speeds.
    Depending on solo or sidecar use it could be ordered with the option of two different rear drive gear ratios. I'll take my R90/6 or R90s on a trip where 600-800 miles is a daily thing going across country, funny thing I can't find the dirty chain and I can go from California to Florida without parts falling off.

    Thanks for the link burninbriar, I've never seen the inside of a Harley gearcase and I'm always looking to learn something new. I was referring to gears in general, not necessarily harley transmissions. In applications where the engineers wish to couple and uncouple 2 gears by sliding one of the gears over on a shaft until the teeth mesh with the other gear you will see straight cut gears. Typically, when you see a helical cut gear it will be in constant mesh with the opposing gear.

Straight cut gears with the assistance of syncro's can be engaged and disengaged quite easily and produce no side thrust.

    I don't know about the 6 speed tranny's but on the 4 speeds all the gears are in contact at all times. Shifting is accomplished through shifting clutch dogs that slide between the gears in effect locking or unlocking them to the mainshaft or counter shaft. Page 26 of this Andrews catalog shows the clutch dogs as figure C.

    I recently (last week) picked up a 2007 FLTR Road Glide, 96CI and 6 speed. Box stock with the full CA emmissions package, it runs very strong from 3-5K rpms. 4000 rpms in 4th is 80mph. 6th is a cruising gear, not worth having below 70 mph. 1st and 5th are straight cut gears, all the others are helical (sp?) cut. Straight is stronger but noisier. 1st for starts, 5th for passing.

    There is no way I'd put a 6 speed on a 80, or an 88 for that matter. Lugging these motors kills power AND fuel mileage. That's why HD only put 6 speeds on Dynas last year - the lighter bike was OK with it on the 88.

    You are right to stay with the 4 speed INHO, given the way you ride. Of course, you could go with a 5 and just use 1, 3 & 5.........

    That bike has to be kept indoors. They shoulda used Pressure Treated lumber!


    TERMINIX Pest Control offeres a Warranty for it as well.

    Kelly;
    Let me know next time you're in town, I'm about 50 miles south of Pittsburgh in Greene County. Maybe you could give me some pointers on this tig of mine.
    You should fill in you're location, who knows, I might be in you're peice of the world some day.

    James;
    A good friend of mine down near Cincinnati Ohio started with a seat he got at a flea market and eventually built himself a Harley. Rose thought he was nuts when he brought the seat home and told her it was there new bike. If you want one, I believe you will eventually end up with one, although cheap parts are getting harder and harder to find now days with the craze thats going on. I also like simple, thats why I did away with the electronic ignition and put a magneto on mine.
    As far as pulling a trailer, they all will do that just fine, unless you plan on trailering you're car to the track with you're bike. I noticed on the speck stuff from Harley that Trent posted they mentioned increased hauling capacity. After you get so big that becomes a mute point. like harcosparky said of his freinds 750 CC BMW with a side car and two passengers, if that can do it, so can any Harley. I wish you the best and look forward to seeing some progress picture's of youre new used bike.

    I think if I were to go with 6 speeds I would want 4 of them set up like my 4 speed and the other two to be about 15-1 at the rear wheel with one of them being a reverse, the other a granny gear for crawling out of hairy places.

    Thanks to every one who participated in this thread so far, I've enjoyed the input.

    i dont much care for the new harlys eather, a harly has always been loud and simple, kinda like an old truck that just refused to keep up with the new tec. its just waht it is, the new ones just dont look or feel harly. although i cant aford one if one was given to me and ihad the option of a new one or an older one i would have to go with the older one if i had to keep the one i chose, if i could sell it i would go with a new one sell it to a yuppie and build myself one frome parts to be just right for me. and it would have a 4 speed, if i did pull a trailor it would be a light one so the 4 speed should be fine. and there is just some thing about a kicker that just has to be there ya know.
