New 150cc LKY2 Hornet Owner-looking for insight By 150hornet (Read 7,893 times)

[150hornet]

Hi guys, I'm new to this forum but hoping to learn from y'all. First time rider and bought the Motobravo 150cc Automatic Hornet. I really like it but want it to last and I'm not afraid of modifications. Realize it's kinda cheap to begin with but would like some additional power and want it to last. I'm not a mechanic and I keep my bike at an apartment complex so no many places to work on it myself. Tech where I bought it said I might eventually want to try a bigger carb and performance plug.
And "jetted" carb but not sure of the terminology. Had also read about gas lines getting kinked, etc. Right now getting 45 mph easily right out of the shop. where do I learn how people are tricking this machine out?
Thanks for your help...also, where on the net can I learn the ins and outs of the engine?

Well the 150s are good for 50+ mph maybe 55 if tuned right and a few not so expensive mods. But if your going to keep it outside I would get a COVER for it. These scoots do NOT LIKE water the electricals are not the best and if they get wet you will have problems. So whenever your going to put it away for the night or its going to rain put the cover on it.

As for modding and getting a little more top end on it we can help with that. But you will have to get your hands dirty and learn otherwise if you take it to a Motorcycle or Scooter Mechanic it is going to cost you. If your willing to learn you will be able to fix your own scoot they are really not hard to work on and parts are cheap.

Welcome to the forum lots a help here there lots cheap and easy ways to get more performance out of these little engine.first thing people will ask is engine code and model ..?

[roketafan]

Lol alley beat me to it

[150hornet]

Thank you guys, definitely willing to learn and get the fingers dirty! Not a problem. And yes, I have been keeping a cover on it ever since day one...which was yesterday! 55 and a little "plus" sounds good to me!
I want to learn but keep in mind I have no mechanic b/g. Like to work with my hands though.
PS: Tech at sales said to disconnect the red wire from the battery when you know it's gonna sit for a few days without a ride. He said the battery drains regardless if in use or not...Please tell me of the inexpensive mods I can start out with, jetting the carb, a new, bigger carb, etc. The model is the Hornet, the 150 auto, motorcycle style scooter. Not sure of the engine code...

Hi, welcome to Scooter Doc forum. The engine is the same as the one they put in their scooters, a GY6. I'd read through the Arrow manual to familiarize yourself with the engine. The manual is an oldie but goodie and still applies to current engines. Look through the Library farther down the site, there's a tremendous amount of material on every aspect of the GY6 scooter. Slapping a bigger carb on a GY6 can be very problematic. The head doesn't handle that very well and it usually causes a host of problems. What most guys start out with is a Uni filter like this one Greg offers at Mainely Scooters:

You'll have to rejet to around a 110 so you'll need to get a few jets around that size to experiment with. If you look in the Arrow manual it shows you where the jets are in the carb. The Eagle & Z Bike manual has some great carb photos and is also a good reference for the GY6. If you get ready to try the filter and jet upgrade let us know and we can walk you through it. Don't be afraid to ask questions, we all started from scratch at some point. Rich

I am NOT a mechanic. But it has been stated on scooter forums hundreds of times that your best place to start is transmission.
See if you can use a performance variator. An easy swap if you can, even for someone with no wrenching skills(like me).
Carb work and BBKs are unlikely to get you as big a gain. 4-5 mph. And it is simple enough to do in an hour out on the sidewalk.
It worked for me as well as built my confidence to try the next thing.

No rev cdi and airfilter and jet gets me to 55 no problem also did my own muffler mod

[150hornet]

Bashan, what immediate benefits do I get from swapping out the air filter? The stock filter and housing is huge on this thing. But I have to say I like the idea. Thanks for the help guys. Do you guys disengage the battery when not using? Also, thanks for all the welcomes. I can tell this forum is populated with great people who are willing to share knowledge! Also, what oil do you recommend after I drain the break-in oil?

[Alleyoop]

I do not think 99.9 percent do not disconnect the battery. Now if your going to put it away for the winter and never start it then yes, bring the battery into the house and also DRAIN the GAS out of the carb.
But a good thing to do is leave everything as is after the riding season and start it up once a week and let it run with no lights on for around 15 minutes to get the gas and oil running through the motor and at the same time the battery gets charged. If the battery is not getting charged during your 15 or so minutes of running then put on a Trickle Charger a good one is the Battery Tender Jr.

The stock air filter is restrictive in the air flow coming into the carb and lowers power . By replacing it with a better quality aftermarket air filter ( like the Uni) your going to get better air flow into the carb and abit more power once the jet and carb has been properly adjusted .
will c.

[sprocket]

Not ALL stock air filter are restrictive...they balance the air in, to the exhaust out...based on the jetting, air/fuel mixture etc.

A Uni will increase air flow, but without a free flow exhaust they don't do much.

Uni filters are OK in some situations, like replacing paper air filters, but they must be oiled to be effective.

Frankly, I think they are a pain in the butt... lots of jetting to get them dialed in and they are noisy, and sticky messy and will cause the carb to vibrate or pull off the air intake elbow, or the elbow will develop cracks...unless the front of the carb is bracketed to the engine...

Sure they are under $20 bucks but the headaches they cause... are 'priceless'...

I guess it depends on what you view as fun...I would rather be riding...

Learn about your scooter engine, change the oil frequently, learn to adjust the valves and when you gain confidence, start by tuning the CVT...but only ONE change at a time...

Safe riding...

welcome to the forum 150hornet glad to have ya my 150cc hits 60 easy with just me on it although im light weighing only 155lbs. all i did was removed my stock air box and replaced it with an after market filter, added a racing orange coil pack, a new orange racing AC CDI, purchased a free flow exhaust, did the tubeless tire conversion, and just the other day i installed a 1.5 amp on board trickle charger by shoemaker and thats about it. with me and my ol lady my scoot still hits 55-60 mph. the total i spent to do all of that was about 320$ which is very cheap. if you want to add those same parts to a real motorcycle, your looking into the 500$ and up range. i would also take a look into the PDI section. happy scootin'

[150hornet]

Ok can most of you guys safely say the stock air filter on the 150 Hornet restricts airflow flowing into the carb? Will I have headaches installing a uni and adding a free flow exhaust? Who supplies the ff exhaust pipe I should get for this vehicle?

[150hornet]

So this is my GY6 scoot. I think the first minor mods I'll do are the airbox and exhaust. Also getting ready for the first oil change after break in period. What oil do you guys recommend?
