converting manual to semi auto???

[pbk]

i want to know if its possible to turn a manual engine into a semi auto (pitbike engine) as i need a semi auto engine but finding it hard to find one and thought if its possible to change a manual to a semi auto and it sort of thought well why couldnt you just whack an auto clutch on instead of a manual clutch???

if your wondering why i want a semi over a manual its for a stunter project im making and also making a custom rear hand brake unit so no room clutch....

if you have heard if this being possible please post here or if you now some one who has done or you have tried or whatever just post here

Cheers

Im not sure though.

yeah it will work just get a semi auto clutch and clutch cover.

 

[pbk]

so thats all i need?

 

[shrimpy]

pit sounds pretty simple if that it

 

[rider456]

and the arm that goes from the shift shaft to the center of the clutch and a few other bits that are in that area to. just need a blown motor to get all the parts off it like a pitpro 110 motor..

 

[pbk]

so does it have to be one of those covers that has a nut on the outside or just a cover that dosent have a clutch cable latch?

 

[rider456]

yeah you need a nut on it thats for the adjustment..

 

[pbk]

so how does say a sme auto lifan 110cc work cos its got the same casing as lifan manual 125cc but with out the clutch latch???

 

[rider456]

prob have internal adjustment??? not sure

 

[headsmess]

the nut on the outside is, as stated, an adjustment screw. inside the engine, this pushes on a swashplate that presses upon the clutch. this is in replacement of the usual cable operated lever...

when you press the gear shifter, the movement is transfered to the swashplate on the clutch, releasing it for the gear shift.(think crf50 and being able to "ride the clutch" when you put pressure on the shifter without actually changing gears...)

the shifter shaft isnt entirely necessary, but... be prepared for some nasty gearchanges if you dont change it over with everything else... cus the clutch wont be releasing on the changes and finding neutral/taking off will kill it...

then the biggest question is...will everything change over easily?... cant say ive ever tried...

well came to conlusion its not worth as it will cost bout 100 bucks for the parts unless some one hasthem laying that i could get for cheap

Looking at that engine and for the cost and messing around I would be just buying a new motor personally.

Hey mate.
Thats not a semi auto style motor so unfortunately you wont be able to convert it. The other style of motor with the clutch arm on the front of the motor is the one you need to be able convert it to semi auto.
