I told you all a few months ago I would report how I liked the New Kasea that was given to my 8 year old daughter. Well, so far it runs well and has about 12 hrs on it. We just moved and have not had much time to ride. But I tell you after following this thing for any length of time it makes me wish I had got her a four stroke hands down!!! It smokes bad and stinks like hell! I used a sink elbow from Low's and put a small K&N on it like a small snorkel. It looks cool and works well after I restricted some of the air flow. If you have a solution to make some of the smoke go away please let me know.

Now I'm starting to look around to see if I can find a certain type of scooter with a 90cc-150cc 4stroke motor I could swap in to this Kasea 90. I'd prefer a fully automatic tranny. So If you have a sayjestion please send it my way. I have welding and fitting experience. So putting a motor in should be fairly easy but need to find the right one.

 

Probably needs to be adjusted. Not sure how you do it but I have one eton viper 90 and my bro in law has two and mine and one of his hardly smoke at all but one of his really smokes much worse then the other two. The four stroke kid quads are just way underpowered in my opinion.

 

I purchased a small quad similar to the Kaesa, but it had a 90cc 4stroke in it. It was ok, but definitly needed some work. After installing a honda 125 carb, open airbox, and exhaust mods, it would finally keep up with our trx90. It was an ok bike for my daqughter to learn on, but the cvt really kills it. I couldnt set the throttle limiter properly, because the cvt needed alot of rpms to engage, then it would just go too fast. I dont know if the 2stroke cvt works better or not though. I ended up just putting the trx into first or second, removing the shifter, and setting the throttle limiter. This worked much better and was much safer.
On a side note, I have a complete honda 125m engine and electronics package(minus wiring) that I would sell if you are interested. I will need a top end job(bore and new piston, relap valves). I purchased this engine to put into the TRX, but the kids are just too big for it now, ended up getting a 250 instead.

 

Far as being ridable the first thing she said after ridding it for a few hours is "It's a cushy ride Dad!" I can tell its much more rider friendly than the old Badger we had. Especially now that she don't have to shift gears. But no one in my family wants to ride behind her that's for sure. I'm wondering if maybe there is too much oil being mixed in with the gas causing it to smoke?

I also removed the restrictors out of the carb, clutch and the walk behind kill switch. I removed the safety switch from the hand brake for starting. Personally I feel it is safer for her on hill climbs if it dies to restart and not have to mess with the hand brake that she can't really grip anyway.

Getusummm can you send me more info, some pictures, and price for the "Honda 125m engine and electronics package(minus wiring)"? And what kind of tranny/clutch does it have? What kind of bike did it come out of?

have you tried jetting it, and maybe changing the oil you run in it.

 

You probably need to rejet with that K&N. The factory intake is pretty restrictive. Also, when you change the intake you need to adjust the mixture on the carb. If you haven't, that might be part of the problem.

I've also heard going to premix helps.



But every 2-stroke I've ever had smoked a little.

 

I did expect some smoke but not to be smoked out. I have rode bikes for 23 years, two and four stroke. But this is by far the worst "new" two stroke I have ever followed. Last weekend I trail rode with a KTM 380 exc and his bike didn't smell/smoke a 1/3 of what this Kasea does.

I restricted the amount of air coming through the K$N because it ran like crap when it was not restricted. And I have play with the amount of restriction but has not made much difference far as smoking. The oil I was given with the Kasea is made by KLOTZ and reads 2-stroke TechniPlate, Motorcycle Performance, Synthetic Lubricant, Injection or Premix...... $10.oo for a Qt.

I have not tried jetting it or using a different two stroke oil. So maybe I should try going up in size on the main jet and open up the restriction on the K&N. Does that sound right? What about the oil any sayjestions?

 

JETTING!!!

 

Ya know, I forgot to mention that jetting part myself. When you increse the air flow to the engine you will definatly have to rejet. I would try 2 or 3 sizes up and go from there. Thats why it ran bad without the resrictions(it was running way too lean). If it is oil injection at the carb, it may be causing it to pull extra vacuum on the oil feed. You may just consider going to a premix, then jetting accordinly. Just remember, that with the premix, you will have to run even larger jets to compensate for the mixture and not run too lean.
The engine is out of an 84-85 honda 125m. It has an auto tranny with 4 speed tranny and hi/low range. I dont have any pics right now, but I can have some in a day or so. I chose this engine because the cyclinder is inline with the engine just like the honda trx90. I dont need the engine anymore and am not greedy, so just make an offer and I will consider it.

 

Mike, you dont need to be such an ***, besides that, if he added more airflow, then he will need to add more fuel. The smoke is from the oil injection, not the fuel mix. With just the k&n, he is too lean.
