HELP NEEDED!

I just put my KPX 150 engine back together after replacing the
rightside cracked crankcase cover. The engine runs fine but I'm not
sure about the hose connection that exits the top of the cylinder.
There's a long black vacuum hose connected to a barb fitting, on the
other end is a hose union and spring clamp. Exiting the top of the
trans case is a similar vacuum hose. I connected them during
reassembly but it created an enormous amount of positive pressure in
the crankcase to the extent that after 10 minutes the exhaust was
blowing blue smoke from blowby and when I opened the dipstick tube
the oil blew all over the engine.

SHould they be connected and if so, how does the crankcase vent?

i have the 125 talon. according to carter, the 125s and the 150s are the same other than the bore. they are yamaha type motors also. i'm hoping that the talons and the twisters are similar enough in order to use the same upgrades.

 

 

my wife and i are looking into buying two buggies for ourselves. i've looked at the carters, yerfs, twisters, and currently the kpx's. is there any one buggie that can carry two adults effenciently? we are on a limited budget though. i want two but may have to get only one. been reading the forum here, where can you get a hop up kit, and i'm not real mechanically inclined, so, what's a cdi box? we just need some good advise, please. thanks..

the best deal that i've been able to find has been at www.familygokarts.com. the only downside to the site is the price of shipping. i have one of the 125 talons and it is supposed to run at 30mph. mine runs at about 36mph right now. i'm also looking for hop up kits for it but i havent had any luck. i've been told that it might take a year or so for independent companies to come out with hop ups. the 150 would be nice, but i too was on a limited budget. if you can spend 1850 you can pick up a 125 talon at rural king. it's a 2 seater and 2 adults can fit in it somewhat comfortably. hope that helps with your search.

 

It was called "Cool Rides" in Loveland CO. Maybe it's listed in the phone books?
I'll grab the number next time I go by and get it to you. It may be a bit, I don't go that way too often anymore.

 

Sitting here at work on the computer I am trying to visualize what you are talking about. I think, (I'll check for sure later) that the one that comes out of the front of the head just vents out towards the back, NOT CONNECTED TO ANYTHING. I think mine lays on top of the transmission and burps out oil every once in a while. I am pretty sure that you SHOULDN'T connect them. This would probably build up a lot of pressure like your talking about.

Hope this helps

If you could tell us what exactly you will be using the cart or carts for then we could probably answer better. I know that I probably wouldn't want to do any serious riding with 2 adults in my Twister buggy, even with my upgraded pipe kit and air filter/jetting. It's a little underpowered for hill climbing. Don't get me wrong, I love my buggy, and the pipe definetly helped in the hill climbing department. Not sure I would go to the trouble of trying to modify a CDI for it.

You might want to look at the independent suspension 250's they are selling on ebay. They look a little more complex, but if ride comfort is what you are after, independent is the way to go. I prefer a solid rear axle for super fun cornering and sliding but to each his own. I do know my buggy goes places and climbs things just about as well as an ATV and it does it in a safer somewhat funner manner! even with the little motor.

good luck!

 

Thanks for the reply. I sort of remember it just laying on the engine but what confused me was the shape of the trans vent line, it has a few bends in it that when oriented properly places it exactly where the engine ventline terminates. The kart runs fine without them connected but I don't want to damage anything long term.

 

Yep, I'm 100% sure now, I checked it last night. It just lays there belching out oil periodically. The other vent tube does look kinda funny, has some wierd bends in it.

Was it hard getting parts for the KPX? I'm sure I'll eventually tear mine up!
