| | Re: centrifugal clutch You have to have a pull start to start it. That is what is keeping my away from them. Those things stink on mower, on bike motors they are worse from what I here.

| | Re: centrifugal clutch It's on the Grubee engine it will be called something and GGG-2 which is pull start and pedal start. I don't know what parts you would need to retro fit it onto an engine.

| | Re: centrifugal clutch I saw the one at Grubee a couple months ago myself. As I'm researching this stuff
constantly I wondered how they got the centrifugal to dual start. I figure in time
it will be quite popular as it would make it more user friendly for women.

Yeah those brakes have been fitted on bikes with fenders for years now. It's not a
problem. |

| | Re: centrifugal clutch my 48cc dualstart starfire gt-2 grubee from gasbike.net
has manual and centrifugal clutch,can be peddal or pullstarted
Dual GGG model; Allows pedal starting as well as rope pull engine start. Uses a friction clutch as well as a special centrifugal clutch with over running clutch lock up to pedal start; Handle Bar Clutch lever must be in the engaged position to operate in centrifugal clutch drive mode. In disengaged lever position the engine is in free wheel mode separated from drive line. Note: A standard friction clutch engine can not be converted to GGG dual mode due to different crankshaft | | Thread Tools | | | | Display Modes | Linear Mode |
