Harbor Freight Clone Help..

[bikerboy1000]

i want my motor to go as fast as possible, i work on air conditioners for a living, dont know to much bout motors...

this is what i have done so far...

1. took govner out...
2. ordered bigger cam, and springs, billet flywheel, and billet rod...

any other thing i can do... i dont race at tracks or nothing just like messing with neighbor hood kids..

how do i replace cam? do the timing dots line up with piston a tdc? how fast , what rpms should i expect to see when i change cam flywheel, rod, springs??

it goes like 39 mph right now with govner out.( waiting on rod, flywheel and cam , springs to come in mail).. its just a lil yard yart...

how do i replace cam?

Why would you order all this expensive stuff and then admit you do not know what you are doing? I'm just sayin'.

Sounds like you have a good start. The rod is the toughest thing to install.. you need a micro torque wrench to tighten the bolts in sequence correctly. You'll also have to reinstall the piston/rings.

Flywheel is a simple remove and replace item (don't use a hammer), and the cam is like you said, install with the marks together and then install the springs, you'll also have to learn how to set valve lash when you are done.

how fast should i run with these mods i listed? im looking to go faster than the neighbor kids, should not be hard, they run 5hp briggs, i had a briggs, slung a rod..

how fast should i run with these mods i listed?

That would depend on weight, tire size, and gear ratio.

You'll find this site has a lot of the info your seeking including the max RPM you could expect with your mods: http://www.affordablegokarts.com/

Then you could use the calculator at this link to estimate your new top speeds: http://www.diygokarts.com/speed-calculator.html

wow.... i dont really see the point in getting a billet flywheel for a clone, granted its lighter and there is not risk of it flying apart (ahem...) but i would ne incline to keep some some weight for the momentum needed to start the engine, but thats just my view of it.
