its all back together and runs like a charm...i need to clean up the plastics a bit but last night i was more concerned about getting it running than making it look perdy

looks horrible...

J/K, looks good. Hopefully the plastic renew stuff works, until you get your new ones that is.

man that thing is sweeeet. u gonna get some aftermarket plastics

Zeppelin03
09-14-2006, 07:35 PM
I want to get some new plastics..i think im gonna keep those thru the winter and buy new ones when i get ym taxes back or something..they were pretty expensive so i didnt need them as a priority so i got other stuff but i will eventualy, im just undecided on which ones to buy because i liek having the headlight because we ride lots of trails at night and such

I not absolutley positive if I'm right, but those holeshot fronts are a directional tire, and I think you have them on the wrong way. If you just switch the sides (right to left and left to right) of the quad they are on, they would be correct. Please correct me if I'm wrong, but Im not sure if having them on wrong is detramental to tire wear, and didn't want you to waste a set of nice tires.

the quad looks great, i actually like the red and blue, but thats just me.

Zeppelin03
09-16-2006, 05:25 PM
i dont think the tires have arrows on them and ive seen them run both ways so im not surte if it matters...maybe it does. if so someone correct me too

ok you bike looks good but if i were you i would buy black mier plastic. you can keep your headlights and i think it would look sick with that blue frame!!

how much did it cost you to rebuild the motor...cause mines smoking like crazy too, and i am def. rebuilding it this summer

Zeppelin03
03-21-2007, 09:31 PM
umm.. total cost on the motor was

100$ for Piston+rings
25$ for valve seals
20$ for gaskets
30$ for valve adjustment...


so 175$ and i did all the work myself except the valves/

Thats not too expensive...was yours making a ticking sound before you replaced everything?

Zeppelin03
03-22-2007, 08:18 PM
yeah...the ticking was the valves

HPIcamaross
03-22-2007, 08:47 PM
k so mine is doing the same exact thing urs was....do i have to replace them or just re-adjust them

Zeppelin03
03-22-2007, 09:02 PM
I took all my valves out to do the seals...all other parts were reused...u could do valve springs while your at it too..but all u have to do is get your valve clearances re adjusted

Here a pic of a blue frame with black plastics. Its my wife's quad. Black will show scratches but almost any color will.

yeah..id love to get some plastics but im set with red..the black does look sick but as long as my quad runs and stuff plastics arent as much a priority as getting a new car and stuff but deff. something im gonna look into in the future..thanks for the pic
