I'll bet it looks great like that too doesn't it? LOL! -- Rayvan

I *love* the XS650 - I've owned several, and trust me on this, it's way smoother than the Brit 650s of yore. It has a 360 degree firing interval - the pistons rise and fall together. -- BMW K1100LT 750SS CB400F CD250 SL125 GAGARPHOF#30 GHPOTHUF#1 BOTAFOT#60 ANORAK#06 YTC#3 BOF#30 WUSS#5 The bells, the bells.....

Harleys haven't had dual fire ignition since 1999. They went out with the EVO. BTW, when I put a single fire ignition on my both my EVOs they sounded exactly the same as before the modification. > The potato-potato-potato sound a Harley makes is due to the firing order.

A piston fires the next piston fires at 315 degrees there is a 405 degree gap a piston fires the next piston fires at 315 degrees there is a 405 degree gap and so on...

None of my H-D transmissions have ever whined. My EVOs and Shovel had a cam whine though. -- Rayvan

I don't routinely see other used bikes selling for over $15K like I do HD's. No other bikes I know of that you can't get insurance for if you can't prove that you've got a lockable garage to keep it in. Which of my statements, exactly, do you take issue with? How much did your Road Glide cost? What's the insurance like on it? What did you get for that premium you payed over other brands? More power? Nope. Better handling? Nope. Better reliability? Nope. More weight? Yup. Better resale value? Probably. Ancient engine design? Yup. Lotta' people ride hogs, I'm not one of 'em but live and let live, no? You want to pay for a heavy chrome-laden slug, it's your money. >> My '99 VFR800FI has gear-driven cams and I love the sound... now that you >> mention it it DOES sort of sound like a sewing machine 'till you wind it >> up. >> Oh, and a previous owner took all the plastic off (with no tools!) except >> for the windscreen... don't worry, it's metal underneath. > > Well, a big whoop-dee-doo for you, Ace. > Gee, Don, I seem to have pissed you off. If you want to correct me with some facts, I'd sure be receptive. Nothing personal, but it really doesn't bother me to have someone slam me with such powerful statements as "whoop-dee-doo for you". Why don't you enlighten me instead of sounding off like a 10-year-old? Dave S |
