The first (and free) mod you should do is a front clutch mod, remove 2 of the 6 weights and it will make the engine stay in the power band a lot better, with just that mod on my son's stock LT80 ( I took 3 out,but most will tell you to leave 4 in) it revved a lot better, and would spin the tires all the up a hill. Like the others have stated, LT80 is a real good modder for this little quad,he races them and does all his own work. But for now,do the free clutch mod, and you will notice a difference right away.

It is a lil time consuming,but easily figured out.
Remove the rear plastic.Remove the 4 footpeg bolts and pull them UP out of the way.Remove the side cover(dont forget the bolt at the 3 o'clock position where the pull start would go)
You will need an impact wrench for the front clutch nut.
When installing,use grease to keep the rollers in place. ALSO make SURE that the lil keyway is ligned up (you'll see) then put it back together.
Have fun

Balance is not a problem.

Cool to see yet another gal on a quad loving it! brings back memory's.
The DG pipe is fine BR>I'd recommend a Moore Racing LT motor.Your 80cc motor will spank a 105 with a stock carb and pipe. BR>I'd wait on gearing till the motor is done.
You can email or PM me.

Don't spend your money on any mods other than a port and clutch job from LT80. I have a motor done by Jack, and with standard carb and pipe, it smokes all the other 80's easily. Trust us on this... several others will testify to the worth of a good port job on this quad!

As for juicing it up see LT80 on this forum. Doing individual mods one at a time will not give you anything like getting a complete power setup from one person, in fact you will end up wasting money and having a bunch of mods that aren't effective. Believe me I researched the heck out of this. The integration of porting, clutch mods, reeds all done in relation to one another is the way to go. LT80 is the best, he specializes on your model. Contact him, he is very reasonable too.

A pipe might be a good idea and new filter

Hello,

I have recently bought my two boys a quad (LT80/KFX80) and was wondering what the best mods are.

I want to put paddles on soon but probably need to juce them up a little first.

Thanks

Thanks for the info......I'll give the clutch weights a try.

How difficult is it to remove two of the weights from the front clutch?

Can I figure it out without a manual?

If you only take two of theese weights out will this throw the balance of the clutch off? Thanks

Thanks for your input LT 80! I have a 8 year old daughter that has been racing her 2003 LT 80. I changer her bars and got her a set of the Team SoBe graffics and then chopped the fenders for her. I put a AC bumper on the front and got her a set of nerf bars. I put the +3 a arms on it got diff tires front and rear. I put a set of works shocks on it the other day. As far as the motor goes it is still stock, I bought a DG pipe before I realized what was out there for this machine for aftermarket parts. I put some boyseen reeds in and put a block off plate on it for the pre mix other than that it is stock. I havent touched the gearing what do you recconmend there as well? I wanted to wait till she was using all the power to do anything else to the motor. Well now she is using all the motor, I was going to try the clutch mod other than that who or what would you recomend to do to hop the motor up for her. I was thinking of the 105 kit but then it wont be legal. I got a new 20mm carb off of ebay but it doesnt have the rubber intake piece so cant put it on. Any ideas or who should be power demon for this little ride? Thanks any help aprreciated!
