you got to admit between him riding it and working on it .I'm mostly standing over his shoulder,it has been fun for both of us, most importantly it has helped keep him off that @#$^% playstation,hes learned to use a torque wrench,etc and I'm thinking I might have a young GREASEMONKEY/GEARHEAD on the rise.Now isnt that what it really all about?

 

Has anyone installed a kill switch on a LTZ 50? Any help would be appreciated.
Thanks

 

There's one under the seat. You could reroute the wiring from the "parent plug" if you didn't want to series a switch on the key.

 

In my opinion, I think this little 50 is bad ***! I have had a blast working on it and enjoy watching my son go way fast on it. We are all reaching the point of no return with these quads but that doesn't make them junk or make us wrong for buying them and making them fast. Its a 50, it can only go so fast! I need to sell mine right now because my boys need to move up but I will miss this little quad and I dont regret any of the time or money I spent on it. I just hope whoever buys it recognizes the work it took to get to that point. But no matter what, if I was standing at the dealership and somebody asked if the LTZ-50 was worth the money, I would say hell yes! Then I would tell them to call me and I'll let them know what to upgrade!

Well said Ed. I have a 3 month old who I hope will enjoy this quad as much as his brother did. It has a number of years left in the family. I have freinds with Kasea's and DRR's and they are constantly working on them or replacing them with new units.

I never did change the CDI. We have some steep hills and my kids are too fearless. I like the CDI speed limiter - at least for now. Also we let a few of their friends ride it, and they really don't need speed. They need gully crossing power. When they need more speed I'll get them a 90cc machine.



I tried pulling three rollers, but wide open it would only go about walking speed. It made me realize that I needed to concentrate on getting more out of the motor. I put the rollers back in right away.



I'm not certain but I think the main jet is about a #75. I forget the pilot size. It's whatever came with the C.T. pipe. Whatever they are it's running rich. The cylinder head and plug had too much carbon. I'm going one more size down on the main jet.</end quote></div>

I think your missing the whole point in regards to what everyone is telling you about ditching the stock CDI. Its wothless in my opinion. The rollers need to be done in COMBINATION with the CDI. YOu can just do one, and not the other. Replacing the CDI is not just about increasing top end speed. The COMBINATION of the new CDI and only using three rollers gives the little bike more power throughout the entire RPM band. All the way from a dead stop up to full speed. Your really wasting your time trying to get more power out of the engine if still using the stock CDI. It just aint going to happen[img]i/expressions/face-icon-small-frown.gif[/img]

Now that being said what is the most miles you/or your kids ever put on the LTZ 50 in a day?

q]

My 4.5 yr old son recently did about 50 miles over a weekend. He complained a couple of times obout his thumb getting sore but that was about it. He's like the energizer bunny[img]i/expressions/face-icon-small-happy.gif[/img]

 

Over the weekend I put on a K&N w/outerwear, 75main, 17.5 pilot and it runs really well. No more hickup off idle like there was with the 12.5 pilot. I did some high speed runs down the street and tHe plug was a little ligher than I like but this was at sea level and we do most of our riding at or above 3000ft so I think I am going to leave it. I picked up a 80 main as well and may give it a try...

I turned the idle up a bit and tried playing with the air screw. Stock position on the air screw is 2.5 turns out. Turning it in just the slightest would drop the RPM's. Turning it out to 3 turns the RPM's came up slightly. I went all the way out to 5.5 turns but I could not tell a difference between 3 and 5.5 turns out. What is the max you can go out before the screw comes out? Turning out leans out the idle circuit (More air) correct?

I don't think I am. I do not want the bike to go any faster than the stock unit allows it to go. If I change the CDI I will have to limit top speed with the thumb screw, which will rob them of power when they need full throttle on hills. I understand the effect of removing the rollers. My solution was to install a 48 tooth sprocket. People who are racing do not seem to be liking the 48 tooth, but I would put a 52 tooth on it if it wouldn't hit the exhaust. I want pulling power - not speed.

Over all I'm satisfied with our current set up. The bike does what I need it to do, in spite of me feeling that it's possible to get more out of the motor. I believe .035 shaved off the head instead of the .020 I did would provide better gains. I'm pretty sure there is room. Maybe my motivation to tinker on it will come back and I'll do the head again. I do think we're missing out on a lot of potential there. My wife's 49cc Metropolitan has way more power and speed than the LT Z-50. It's running 12:1 compression. Someone here mentioned we're at 8.4:1 - which is quite low.

Unless the other CDI has a different timing curve then for what I want an ignition is an ignition.

 

Hey EagerJeeper Iwish you were close by I'ld let Ya try out the CDI w/3 rollers out it REALLY brings these things to life .Its not timing curves or any thing else it just gets the RPM up into the power band shave some weight off the driven clutch shoes .If your in Maryland e-mail me
see ya
