Predator copy questions

[willuum]

Hey all! So i'm looking to build my own Offroad go kart and i have everything i need sorted out etc. Expect the engine and clutch etc.
So the problem i'm having is that i'm from the EU (netherlands) and that i can't seem to find any predator engines around. Only honda and copies! So i found this 13HP predator copy from LIFAN.

http://www.wiltec.de/engines-petrol...uction-clutch-gearbox-go-kart-air-cooled.html

So the thing is that i'm wondering what this reduction gearbox does? Searched things about it up and can't seem to find anyone having something like this on a go kart. Is it like a torque converter? And if i would go with this one should i get a normal centrifugal clutch with it or a torque converter?

Thanks in advance! (sorry for bad english )

Get a 40 series torque converter for the 13-14 hp motor.

Okay ill write that down but do you have a idea why there is a reduction gearbox? and what the h does it do

 

[ezcome-ezgo]

It reduces the speed of the engine by half.

Hi fellow european

first:
if you ever want a Torque Converter for your engine,
DO NOT BUY one with a reduction gear box!

the same shop sells engines without it as well (either pick 1" or 3/4" shafts [25.4mm or 19.05mm ])
that way you'll likely only find eninges w/o reduction gear boxes

And yes, PTO size is important for getting a std dry clutch or a TC mounted,
there is no TC with metric bore and this way you can easily fit the ones that are available.

And now the most important thing (since it drives me nuts)
The predator ITSELF is nothing but a clone!
Honda gx200 is the original engine, everything else is either a direct replacement (Briggs, Kohler, Subaru) OR a clone (shameless copy of the honda [like the lifan engines] or a mix [like the predator])

You want a predator engine, buy the non-renamed engine (Rato R210) since that's what the predator actually is!

*venting over*

Personally a wet clutch is great but for a go kart I think the TC is a much better option,
since it offers variable transmission whereas the wet clutch (wich is an essential part of the gear reduction box) is a single speed only.

'sid

PS if you pick a 9hp or less, the series 30 TC will fit nicely, more hp, you will need a series 40 TC, both can be found on ebay for rather cheap (but terrible shipping mainly from the US I'm afraid)

Already found some located in the UK that ship to the netherlands and i will go with a 40 series as i'm planning on making a buggy
Anyways the rato engine you mentioned seems to be something in australia only? Also do you think any of these wiltec engines would do? without the gearbox thingy ofcourse haha.

 

[itsid]

you can get a 15hp (Lifan 190) 1" shaft for the price of the 13hp you linked
(no gearbox, no e-start)
http://www.wiltec.de/engines-petrol...ne-15-hp-recoil-1inch-go-kart-air-cooled.html
or with e-start for a few bucks more:
http://www.wiltec.de/engines-petrol...w-15hp-electricstarter-420ccm-air-cooled.html

and likely that's the one I'd get.

the UK shop (if that's the same I've seen at least)
is still more expensive than shipping from the US!
http://www.ebay.com/itm/COMET-TORQU...534688&hash=item48999f0dc7:g:3f8AAOSw7pNZpgEJ
(just over 100€)

rato is a chinese company, and yes... they're widely available in australia (even have a dedicated australian website iirc)
and russia btw..
but you can get them everywhere.

Shouldn't it be the 40 series if it's a 15hp engine? Or am i doing something wrong

 

[mckutzy]

Hello and welcome,
Rato are good motors... Here in Canada, we can't get the Predator brand motors as they are from the states... But we can get the original brand(the Pred is a rebranded make) for almost as cheap...

yes, it should.. you see me baffled...
funny thing is, I swear I was looking at this auction:
http://www.ebay.com/itm/40-SERIES-1...ONVERTER-KIT-MANCO-COMET-203785-/332097148136

but somehow got the shipping fees from that other one (must have clicked a link inbetween not noticing )

my fault.

boy that shop sucks you dry on shipping just like BMI tries to

still more expensive than I had in mind:
http://www.ebay.com/itm/40-Series-G...Clutch-Pulley-Set-Kit-Comet-40D-/190950802319

but still cheaper than that rip off with shipping wakeboarder

I'm glad you can; over here, the R210 is AUD$245...

All of the 40 series torque converters are without a kit or something or is it just me

 

[mckutzy]

Reg price at most places, are about that CAD.
I lucked out one time got mine for $99.... On a clearance sale...
Would have bought the other two have I had the cash at the time....

they are, reason being you should run it inboard which means you cannot make a mounting plate like for a series 30;
it can be modified to run outboard with a reverse wound spring
(which means the driver should float 7/8" and thus a plate still makes no sense)
GPS made a plate and sells a kit (non floating, with a crooked belt at low speeds.. I don't like that too much tbh... anyways.

No, no kit, likely without belt, surely no jackshaft
mostly just the two pulleys.

get a jackshaft mount the driven, measure thedistance and order the matching belt (before mounting make sure there is a belt for that distance in the first place )

'sid

PS Yes, a TavKit is more convenient but that'd mean a series30 (8hp max rated works considerably well with ~10hp)
