Couldn't be any easier

Put this on my machine in about two minutes. It definitely dropped the sound volume a noticeable amount without any loss in power, and it still sounds good. I am not a pro or amateur racer so the power change might be noticeable to others. For my purposes this was exactly what I needed to quiet the ATV yet keep my performance high. It was simple to install and if I want to remove it that will be easy too. Definitely recommended.

Replacement Baffle for CRF 230L

I bought a used CRF230L and the previous owner had removed the baffle. It was soooo loud and annoying. The OEM replacement was around $100. I bought this piece and it's working out. There were two challenges on the installation. 1) I had to file the opening to the exhaust about 1/32" to get the spark arrestor to fit. 2) the three pre-drilled holes were not aligned with the mount points on the exhaust. I used a round hand file to remove about 1/8" of material from the holes. After that, I used #6 bolts to mount the unit to the stock exhaust.

Pro Circuit Quiet Insert With Spark Arrestor - 3.5

I bought this part not certain that it would fit my TTR125. There were apparently older models, pre-2006, with different exhaust diameters. When the part arrived, it bolted right on, no problems whatsoever. Now my bike is much quieter and the spark arrester allows it to be ridden on public trails. Without this insert, my bike was quite loud and I was hesitant to ride it at my friend's track or on the road (bike has a light kit and is street legal) and attract unwanted attention.

Ok

This spark arrestor is ok if you like endless hours of work! I had to cut and grind things down just to get it to fit!

Q: Mounting bolts?

Does your Spark Arrestor come with the three mounting bolts? If not, would you happen to what they are on a CRF 230F?

A: The Pro Circuit Quiet Insert With Spark Arrestor comes as pictured. There are no mounting bolts as those would be part of the endcap. Keep in mind, this insert is ONLY for specific models of Pro Circuit exhaust and will not fit any other brands of exhaust. Please read the description on the product for detail.

A: Unfortunately this will only fit Pro Circuit mufflers and will not fit any OEM/stock mufflers. The only one available for the stock exhaust is the OEM spark arrestor assembly from Honda which can be found in the OEM parts Fiche here: http://www.motosport.com/dirtbike/oem-parts/HONDA/2005/XR650R/MUFFLER

A: You will need to measure the diameter of the can. The easiest way to do that is to remove the end cap and measure across the opening. You will need to know the outside diameter. These are available for either 3.5 inch or 4 inch diameter cans.

Q: How do I know if I need the 3.5" or 4"?

I am wondering where it is measured from.

A: Best way to find out would be to either contact Pro Circuit, or take your stock cap off and measure that. Normally all the MX style bikes like the 250f and up run the 4in and the smaller trail model bikes run the 3.5in cap.
