Everything sounds awesome except for the hotcam, your money wouldmbe better spent on a megacycle or web

Hotcam not a good company or is it not worth getting a camshaft?

 

[Hdale85]

Consensus is that there are much better cams out there then hotcams.

Alright I'll get looking into a different camshaft. Anyone know any good oversized carbs?

 

[beastlywarrior228]

Sick thanks,you know what the size stock is? and if I got one of those oversized carbs would I need to rejet or just use the jets I have now?

 

[beastlywarrior228]

36mm i believe jetting will be a trial and error with those

 

[duneracerweston]

You will need to rejet and I recomend the 38mm and stock is 36mm

You sir are really giving my brain a work out today!!! LOL J/K


Looks like you have the right idea. Always best in my opinion to get all the supporting mods in place, before you go motor mod crazy!! And it will happen!!!!!!!!!!

 

[ryder133]

Ya imma do 38mm and rejet after the list.

IMO web cams or powrol are the best cams and what tipe of riding do you do?

Fast trail riding. But whatever comes my way I like it all :iagree:

 

[duneracerweston]

Then you need a midrang cam so like a web .430/.390 or a .415megacycle cam is somthing like what your looking for

Sounds good, I am going to be getting a oil cooler soon with hayden cooler.

 

[ryder133]

Guys I don't know if I should get the oil cooler yet. Or wait an get something else like a bumper or such. Overheating just isn't a problem right now and I do live in Canada. What do you guys think?

 

[Hdale85]

Do the oil cooler, it doesn't cost that much and running cooler will make your warrior perform better.

I am just not having any problems at the moment with that.

 

[Hdale85]

Even if you feel it's not running that hot, it could still be a benefit.

Ok well now I am deciding on braided line or rubber
fin rad or heat sink.
