I have a LRD, I love it, its built awesome, builds good low end power. Tha only complaint I have is, its heavy. I like teh Sparks, the Thunder Alley as well, and people have been raving about CFM.

 

i never said it for 450r, i said it for 400ex

 

does ne body know how the whitebors' E2 silencer works? i like the idea that it can be qiuet when i got to trails and it matters, or that i can let it be loud at the dunes. also, i've heard good things about the whitebros carbon pro full system. it's a race only 1 peice system and it costs a lot of money, but i talked to a guy that has one, and i read a mag review on it, both said it's an awesome exhuast.

 

Re: HRC power up kit
Hi, wonder if you can help me decide how proceed, my TRX 450R is due for the 20 hours service which they will adjust the valve wonder if I should order the HRC kit and have them install while they take of the valve cover.

Re: Exhaust
Would a slip exhaust and jet the carb will do the job, or I have to purchase a full titanium or a full carbon??

 

No they wont adjust the valve on the 20 service. I just had mine done and all they do is clean the air filter and change the oil. NOTHING MORE unless you want to pay extra. Only buy the HRC kit if you want the cam, nothin else is worth much. Several companies offer cams and pipes. You dont have to buy titanium or carbon, only if you have extra money. Buy a complete pipe not just a slip on you'll be happier in the long run

 

I put a HMF full system & a K&N on mine because I wanted the spark arrestor. The low end and middle are much stronger now. I had a 13t front, but now I have gone back to the stock 14 and this feels just right now. The guys at HMF were great to deal with. Now it sounds intimidating like a thumper should.

 

Thks Speedbump for the advise, as far as cleaning the air filter and the changing the oil, I do that every single ride both tran oil and engine oil HP4 and HP4M good thing that's Honda have 2 different oil compartment for transimion and the engine that's funny why don't the YFZ?? That's funny blue.
