just came across this today and was wondering peoples thoughts on that 5 speed

oh and if you know of any other source for gy6 manifold risers

If you need a manifold riser to clear the motor mount, that looks like a fairly nice setup. Even with all the tools that I have at my disposal, it would be hard pressed to make something for that price. Just the price of materials and the time to make the price pretty attractive.

putting a riser on my buggy, getting the manifold bolt studs out is proving to be a pain.

I believe (syc) has it and (buggypartsnw.com) has the riser also.

Stud remover kit and wd-40 will do the trick for removing studs

Did you try double nutting them?

Dont want to hijack this thread, but, yeah double nutted, bottom nut just smooshes, I'll buy some quality nuts at the depot or something, these were the nuts that held the stock intake down..

As much as I like the convience of the CVT, I would love to be able control my buggy with an automatic clutch system.

I pulled mine out before I shipped the engine, and they came out pretty easily. The old school stud removers are not that expensive and can normally be found at the parts store. They tend to chew up the threads, but since you are not reusing them, no worries.

Just don't break them off. Some penetrating oil and/or heat can be a big help along with some patience. I pulled the intake and exhaust studs out using the double nut method with no problem. I installed them the same way.

yup, $30 at autozone for a set of metric extractors..suckers popped right out :) 6mm size for the studs. FYI

Just looking at the engine in the video, it did not look like a GY6 engine.

I need to remove my intake studs from cylinder head. I am reading this correctly? You used a stud remover? Hopefully that will be one of the tools autozone rents out, for me anyways...

yup they rent 'em too

I know, I know... back from the dead
 

I know this is an old thread but for the sake of anyone who stumbles across the title:

Lifan 125cc

the engine used in the video is common in pit bikes and small motorcycles and dirt bikes. I've seen them used for "shifter" carts as well. it's not a GY6 but seems nearly as common and it looks like some parts may be shared (ignition parts and potentially the carb and starter on some models)

That is the CT-125 engine used in pit bikes, the CT-50,70,90,and 110 were used in small buggies with some having a 2 and 3 speed shuttle shift transmission with reverse. The 4 and 5 speed transmissions were all manual shift and have no reverse.

There are also 125/150 versions on the chinese 4 wheelers with reverse. Maybe a 110 but I've only seen the forward only ones. Not sure of the number name of them.

It's a Lifan 125cc semi auto 4spd.
It can cruises around at about 65mph no problem, and can go faster depending on the sprocket used.

I need one of these to help me with that cross brace.
