Im telling you man, the Curtis Sparks is the BEST EXHAUST OVERALL IN EVERY ASPECT...........ask any racer

 

I have not been up to Hungry valley with my YFZ yet. I want to soon! I wouldnt worry about it really, they are more concerned
with spark arrestors, they will check for these upon entrance ususlly. A great time to come in the park is at night, no one at the guard post
but in the morning you better go down and pay for your stay. Sometimes the ranger drives around collecting and inspecting.
I might go down to Yoshi in Chino and buy a different insert (just in case)..

Make sure you mod the carb and take the airbox lid off when you put on this pipe!

 

ok so jhead if you coudl email me up at Vinny3299@aol.com then we can talk and you can give me the full run down on what ups i need to do to make this pipe run properly and the right way...

 

Just view the details in my profile, its all there..We should always share our information with others
who have YFZ's, it allows us to further enhance and learn whats out there it no $expense$ and or costly reasearch.
you dont need the protec fuel screw by the way I just use it because i can turn it with the carb still attached if need be.
the carb is not hard to take off and work on I can take it off and change the Main Jet, Pilot Jet and Needle, if I have to in less than 15 min and re-mount it...

yeah i got the emails reading them as we speak... thanks for the info and hopfully everything will run well..

 

well dirt wheels did a exhaust test for the yfz450 not to long ago. dr.d won. thats what i have now. it is soo sweet. great power gains. u would be stupid not to get this

 

Where are you located? Lets race.....

 

yea lets burn it up.... i heard that dr d is ok and talked to a few dealers locally all had to say the yoshimura was the best for the yfz.... also everyone on here said the same mostly... but hey its all personal preference

 

I heard that the stock pipe is better than any aftermarket pipe.

 

and i thought i was new.... just like on a car the exhaust that comes on the car is ok but aftermarket is always better
