Great material!

I bought this for my 2009 CRF450R and it fits perfect! Not only I’m happy with the product it self but the shipping too!

Bikemaster plug

It doesn’t fit my FMF 2 stroke silencer. Falls right out.

Poor fit in my two stroke exaust

It wasn’t a big expensive but the material used was to rigid and It can not firmly press in the exaust hole tightly had an fmf one b4 and it fit tightly enough that I could leave it it during transport of my bike I’m afraid this one would fall out

Can't go wrong

I had to snip off the first 2 or 3 ribs before it fit in my turbinecore2.
Works fine though.

Check your exhaust size and go for it.

Gets the job done

I use this in our 2 strokes since they have the smaller diameter silencers. I just wish it was a softer rubber compound like the FMF version I use on my 450.

Works great

Fits the FMF Shorty silencer on my 01 cr250 just fine. Keeps the moisture and crud out of my exhaust and gives me peace of mind.

Muffler plug

Although this plug is hard it still fits in my 525, I have a smaller one for my 125 but they both fit and work perfectly for when washing my bikes and keep the water out of the exhaust

To hard

They are to hard so they don't stay in the exhaust

Answer: Yes, this will work on your HMF Exhaust. These plugs are pretty generic, meaning they will fit a variety of exhaust sizes.

Answer: Unfortunately we do not have a list of exhaust outlet diameters. I suggest measuring your muffler outlet and comparing to the plug sizing.

Small:
Minimum diameter of 14.75 mm / maximum diameter of 37.75 mm.

Large:
Minimum diameter of 33 mm / maximum diameter of 61 mm.

Question: What is wrong with my exhaust/Dirt Bike?
Question asked Over 4 years ago
I had just bought this product about two weeks ago and place it in my exhaust when I am not riding. I went to ride my dirt bike and when I started it took about 7-10 tries to start it up. It usually does this, but it is probably me because I am still kinda learning how to start it properly with giving just enough throttle. After 5 seconds of it running I see smoke coming from between the engine and the Fatty Pipe. So I turn it off right away and see I still have my muffler plugged in. I have a 1997 Honda CR125 2-Stroke and I am used to it smoking a little because it's a 2-Stroke, but now it's smoking a lot. It also leaks exhaust oil between the Engine and the Fatty Pipe, and also between the Fatty Pipe and the Muffler. I rode it a little on our property and realized it has lost a lot of power now and it shuts off when I hold in the clutch to brake. What is wrong and what would I need to do to fix these two problems?

Answer: I can't tell you exactly what the problem is. But if I were you, I would go find a near by magazine rack and pick up a copy of ATV rider and look for the section called (ask Mikey). Several people send him questions about mechanical issues with their machines and he has a very good reputation for giving good advice on making repairs. You are probably not the first person to have that happen to that particular bike. Hope that this is helpful. Good luck!

Answer: It sounds like your 1997 Honda CR125 is running rich. I would check your jetting and fuel pre mix ratio. Pull the spark plug out and see how it looks. How many hours are on the top end of your CR125? Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

Answer: I can't promise it will but I'd bet on it. Mine is a large for a yz450f with Dr D exhaust and it fits it like it was made for it, and they have quite a lot of notches to be very universal

Question: Which one?
Question asked Over 5 years ago
I have a 2014 crf250r with the dual exhaust. The holes on it I believe are smaller than a single exhaust. Should I get the big muffler plug or the small one?
Question answered by MotoSportGrantK
User's contributor status: MotoSport Staff
Question answered Over 5 years ago
Answer: For your 2014 Honda CRF250R with the dual exhaust you can go with the large but may have to trim to fit so I would recommend going with the small.
