Which Whizzer?

You Think So?

Well...maybe I'm a bit hasty, but I think I've made up my mind........no........I KNOW I've made up my mind!

It's the blue machine with the automatic centrifugal clutch! :)

Now I only have 3 days to change my mind before I buy it!

What's the most important event coming up within the next week?

The Presidential Election? :mad:

Nope!

It's MY BUYING A WHIZZER MOTORIZED BICYCLE! :D

Hi again Hal
Low rpms are cool but you must remember that the Whizzer engine uses a splash oiling system so low rps (under 1000) are not good for the engine. Also the auto clutch is designed to slide into lock at about 2200 rpms so chugging may not be possible. That being said I love my auto clutch now that it is broken in.

Hey Jim:

Well now, that's a disappointment! I was hoping the auto clutch would take hold just above idle!

Is there an adjustment on the pivoting centrifugal weights inside the clutch that will allow an earlier engagement?

Maybe it's back to the slip clutch again!

Darn!

I believe that lugging this motor especially when starting off is bad for it. You will find that once engaged it will remain so at much lower rpms than 2300. Then when you roll the throttle it will slip just a little until the rpm comes up again. All in all I like the auto clutch operation. It seems well matched to the engine operation. The CVT worries me if for no other reason than it is a reinvention of the wheel and replaces an auto clutch that once modified will be bullet poof IMHO. The manual clutch I did not like and suspect that frequent belt replacements will result. Low speeds and stop and go were a pain IMHO.

PS: my idle is set at between 1100 and 1200 rpm and it seems to do well at that setting. I am also assured that I will have adequate oil splash to cool and lubricate the motor.

Hi Hal, The automatic, once enguaged, will still continue to pull as low as 800 RPMs, unless you stop the bike. The automatic can not be adjusted or changed enough to alter the enguagement speed, but you will easily adapt to lower speeds by using the throttle. I have most of my motors set to idle around 1100 RPMs, but at idle with the clutch enguaged the bike will easily travel at 20 MPH, and if I want to go a little slower I just tap the brake to arrive at a lower speed.

Have fun,

HEY QUENTON:

You said that at your 1100 RPM idle, your bike will go 20 MPH.

Assuming that the engine will wind up to 5500 RPM, that would give you 5X20, or 100 MPH!

Anyway, I'm glad to hear that low-speed operaton is possible with the auto clutch!

Yup Quenten exactly what I find also and in most cases at the lower speeds letting off the throttle will not net a reduction in speed unless I am on an incline. If I want to go slower I have to use the brake and once slowed it maintains that speed. I should have specified that I make sure my idle is never less than 1100 and would rather see a small amount higher as opposed to anything lower for cooling and lubrication purposes. With the 70mm you can go slower than the 90 but the 70 is not as fuel efficient.

Maybe I should qualify my earlier statement agreeing about liking the sound at low rpms. I do enjoy that sound, but I don't by any means lug the engine by staying at low rpms. I'm referring to the sound when I'm starting to accellerate. Because the auto clutch equipped engine is usually at a higher rpm at the lower speeds, it sounds like it's working harder. I like the sound of the engine when it's getting up to speed. It just has a really nice powerful note at the lower rpms.
