Hello Guy's,
I was looking at past posts for the Trailboss 330 and saw where someone said "RCR knows alot about the 330 engines". Said there was a cam available for the 330's. I would like to know who or what RCR is and how to find out about what mods are available for the 330 engines. I search the internet from time to time and NEVER find anything. I would also like to know what carb jets to get to improve my performance (if any). I have done about everything I can think of to my quads except engine / carb mods. I need to update my pics but if you look at my sig / webshots you will see. Any Trailboss owner's see anything I have missed. I am trying to show up the 4WD's where I ride. Thanks for any leads in advance.

 

If you want my input I would ditch the bigger tires and the HSP clutch kit.Go with a slightly stiffer secondary spring(what secondary spring is in the kit?)Go with either the EPI pink primary or EPI red(close to polaris white) go with stock weights.Drop in a K&N air filter (no need to rejet) This set up with stock tires will get you a top rpm of 5900-6100 and top speed close to 55 mph.
Your bigger tires are robbing your power.330s are not power monsters but do have decent power.Ricks cam and pipe add more but for me I am happy with the way mine runs.

 

Top end speed is not what I am looking for. I need low end power and all the ground clearence I can get. Where I ride it would be impossible to get around if I went with a smaller / lesser tire. I was running 25" Mud Lites and just recently ditched them for the 25" Outlaws. The HSP clutch is exactly what I need for the type of riding I do. It allows the engine to rev up more before it engages. With the set up I have I can easily pull wheelies and throw a pretty good roost in the sand even with the Outlaws. I am looking for faster throttle response / low end torque now.

 

I really dont think you will get the lowend with the clutch kit you have.You may look into the Heelclicker kit.It produces lowend power.
To get more lowend power your going to need a clutch setup that engages low and has a high shiftout rate.That is where the pink spring comes in.With the CVT tranny you cant always have it all.That is why my recomendations have been check with a tach to be sure what I am telling people.
