Modifying my 6.5 Clone

[Bighomedog11]

Hey, I am thinking about starting to Modifying my 6.5 Clone. I already know i must get a Billet rod and Flywheel. I am wondering after those two things what should i get next? There is soo much stuff they have out there and i dont know what to get for the performance i want.

I am trying to get more power and speed.. Basically more speed but i need power also.


I have already removed my governor..
And i also already made a custom pipe

Please tell me some stuff i should get to meet my goal. I am not trying to spend a arm and a leg on the parts so try to show me stuff with reasonable prices.

Do a search for 6.5 clone mods, engine mods, things of that nature. There has been alot of posts about it.

You dont need a billet flywheel. The myth that they explode is just that, a myth. there is still a possibility though.

Parts you should get:
Billet rod
high flow air filter
high flow exhaust
New jet(must rejet with increased air flow)
18lb valve springs.

Yeah, I run my engine hard now with a removed governor only and a pipe.. Motor has yet to explode.

But i have a custom pipe already.
So i will get a billet rod and a air filter and rejet

With those mods will i notice a gain in power/speed?

Also what size jet should i get?

With those mods you will get more rpm, and a bit more hp.
I would get a numbered drill bit set and drill with your fingers to the next size, try it, and keep doing this until the engine runs good (you can check by checking the spark plug)

The only mod of those that'll add more torque is the filter/header. Valve springs allow higher rpm and the rod makes it safer.

It all depends.

Alright, I understand..
What a good size jet i should start off with? I am in Georgia. I rather buy a jet then drill them. Just in case i mess up i can go back to stock..

Also do the stock carbs on the 6.5 clone have removable jets?

Those mods are the basic.. Cheap type mods?

Then after i get those mods, i should get a different cam and so on?

with a filter and pipe, try a common size, #90.

heres a georgia kart shop ive bought from before:

home page: http://www.robertskartshop.com/

drilled main jets: http://www.robertskartshop.com/p/clone_engines_parts/DJ-1245D.html

great company and shipping to CT was super fast.

 

[Bighomedog11]

I am in Georgia also. but they shop is about a 1hr 12mins away from me. So will just order.
I will probably order from a different site though because they dont have the 18lb valve springs.

Man, your really pushing the outer limits of this myth thing lately.

How can you be so confident his $3 flywheel didn't happen to have any manufacturing defects or it hasn't somehow been damaged, and it would be 100% safe with these mods running wide open at 6500rpm?

Isnt a billet flywheel lighter anyway? Less rotational mass ftw amirite?

Yeah, but but my point was just that once the mods on these engines includes 18lb. valve springs, a stock clone flywheel is more likely to show any latent weaknesses it may have.

Ok, ok, ok. Ill be sure to include that there is a possibility of detonation. Wording changed^

Well i am smart enough not to keep my foot WOT for along time. I usually can tell when the motor is over revving then i let off the gas.

How much money you got to spend?
