It comes with an aluminum hanging band, is it better to use it? Q15. I would like to purchase parts for the chamber silencer. Q16. Is it possible to order individual parts of the chamber parts? Chamber Q & A Characteristics Part 1 Q1. What are the characteristics of the newly released stainless steel chamber? A. We would like to inform you about the performance of the stainless chamber below. The power-up with the chamber installed will be increased to about 55 horsepower. If the limiter has been cut, 60 horsepower or more should come out. Although there are differences depending on the engine condition and measurement conditions, please expect a significant power-up that you can experience in actual driving. The power band is equivalent to normal at 5000 rpm or less, and from there to 8000 rpm, both torque and power are higher than normal, and from 8000 rpm to 13000 rpm, it becomes a full power acceleration range at once. The over-rev characteristic has a margin of 13500 rpm, so it is designed to handle various situations . (Otherwise, you won't win the race ...) All chamber mounting is bolt-on design. All installation is completed with the attached parts. Q2. Please tell me the difference between the racing chamber and the JMCA chamber. A. The race chamber and the JMCA chamber have the same body, but the internal structure of the silencer is different. Both have a straight structure with almost no difference in performance or volume, but the JMCA type is manufactured with a special material and structure to suppress the reduction of the muffling effect due to oil, so the price will be high. .. Both are maintainable and will be restored to new condition if maintenance is also performed for racing. Maintenance fee ¥ 7,350- / 1 piece 2 pieces set ¥ 12,600- Currently, there is no setting for JMCA and racing in the chamber lineup, and only one type is set according to the in-house standard value. Of course, it has cleared the volume standard value. Chamber Q & A Characteristics Part 2 Q3. Is it possible to use the race chamber on public roads? A. When you hear the word "race chamber", it seems that many people have the image that it is peaky and has no bottom and is difficult to handle. The circuit is also designed with a one-lap course that combines low-speed corners such as hairpin corners, high-speed corners, and straight lines. Therefore, you cannot run fast unless you have enough power from low to medium speed to high speed. Also, since it is a commercial car, it is different from a racer that can change the mission gear finely, so it has a wider power band and you can not win unless you have a chamber with excellent overrev characteristics. Such a concept is firmly alive in the dogfight chamber that has achieved consecutive victories in the fierce battle SP250 race with machines such as NSR250R and TZR250R. The power band is equivalent to normal at 5000 rpm or less, and from there to 8000 rpm, both torque and power are higher than normal, and from 8000 rpm or more to 13000 rpm, it becomes a full power acceleration range at once. The over-rev characteristic has a margin of 13500 rpm, so it is designed to handle various situations. (Otherwise, you won't be able to win the race ...) Currently, there is no setting for JMCA and racing in the chamber lineup, and only one type is set according to the in-house standard value. Of course, it has cleared the volume standard value. Q4. What is the difference between an aluminum silencer (blue) and a carbon silencer (black)? A. The big difference is how it looks. Our characteristic blue aluminum silencer and high-class carbon silencer. Both are manufactured with the same dimensions, and there is no difference in volume or performance. Speaking of sound quality, the carbon silencer feels a little bass, but you can hardly tell the difference. Carbon is lighter in weight by a few grams. (Aluminum has a lighter specific gravity than titanium ...) Therefore, I think that you should really choose it according to your preference. However, although it is damage against falls, aluminum may be torn if it is scraped or dented, and in that case it cannot be repaired and needs to be replaced, so if you use it for racing etc. We recommend an aluminum silencer. Chamber Q & A installation Q5. Can I replace the chamber myself? A. This is possible if you have tools at the level of in-vehicle tools. Reference: "+" and "-" screwdriver pliers hexagon wrench, 5mm spanner, 10/12mm box wrench, 10/12mm Q6. Should I use liquid packing when installing, even if I am using chamber O-rings and silencer gaskets? A. Apply to the mating surface of the cylinder and flange and the silencer gasket. Silicone grease is sufficient for O-rings. Q7. I am thinking of installing a chamber on the NSR250R (TZR250R). Is it possible to use normal steps, and can I use tandem steps? Do I need to cut the cowl again? A. The steps are normal. Tandem steps are also available. It is a contact with the cowl, but there is no problem on the left. On the right, the cowl part after the step touches. There is no need to cut, but in the case of NSR250R, the cowl cannot be bolted. (It can be fixed by putting out a stay etc., but there is no problem even if it is not fixed) The cowl contact part does not melt in normal use, but it is perfect if it is protected with a commercially available heat insulating tape etc. Q8. I have a back step, can I attach a chamber? A. Although it depends on the manufacturer and dimensional data, if the normal chamber can be installed now, our chamber can also be installed. When designing the chamber, the steps are designed for normal use. Tandem steps are also available. Chamber Q & A setting Q9. My vehicle is in almost normal condition, can I use it without cab setting etc.? I am worried that there will be no adverse effects on the engine, such as the air-fuel ratio becoming thinner. If setting is required, we would appreciate it if you could tell us the specific method. A. No setting is required in the normal state. When running on a circuit, start MJ from 10 to 20 up. For the plug, IU01-32 from Denso Iridium Racing is recommended. Gasoline is basically high-octane. In addition, it is safer to use the oil used for separate lubrication to prevent seizure as a mixed gas at a ratio of about 50: 1. Q10. Is it okay to remove the air cleaner box? A. The current vehicle has severe cab settings depending on the intake port size and displacement of the air cleaner box and the carburetor diameter. Therefore, increasing the size of the air intake of the air cleaner box, removing the lid, and removing the box itself require a major change in the cab setting, and unless you are a professional mechanic with solid experience, it is less than normal. It will be difficult to handle. In the worst case, it will lead to troubles such as burning, so we do not recommend it. Q11. Please tell me the setting when I replace it with an external air filter. A. If you install an external air filter or power filter, please check the recommended data such as how much the transmittance improves for each manufacturer compared to the normal, and the necessity for changing the cab set. We do not recommend installing products for which such values have not been set or measured according to the contents of Q2. Chamber Q & A maintenance Q12. Should I clean the inside of the chamber (with a cleaning solution, etc.)? If so, please tell me the specific method. A. Perfect cleaning is not possible, but the performance can be maintained considerably just by cleaning the area where the doorway can reach with a wire brush or the like. If you wish, we will do the cleaning. 1 bottle ¥ 7,350 ～ Q13. The silencer is getting louder, should I replace it? Or can you OH? A. The silencer can be OH. External scratches cannot be repaired without replacement, but replacement of sound deadening material and cleaning of internal parts can be maintained. Maintenance fee \ 7,350- / 1 bottle 2 bottle set \ 12,600-. Please send it to us by Takkyubin. OH will be supported in about one week. After completion, we will ship the item by cash on delivery. Q14. It comes with an aluminum hanging band that attaches to the silencer. Should I use it? Since it is rarely used in your company's HP image ... A. No silencer band is used in the DFR chamber. Just like the engine mount is rubber mounted, if the vibration is not absorbed somewhere, it may cause problems such as cracks. In the DFR chamber, a floating state is created instead of being completely fixed to absorb vibration. Even so, excessive vibration induces the silencer to fall off or crack, so we have dealt with it by arranging rubber joints and rubber mounts in place and connecting them. Q15. I would like to purchase two new chamber O-rings and two silencer gaskets. Is it possible to buy them online? If possible, please let us know the application method, payment method, shipping method and procedure. A. Mail order is possible. You can order from the repair parts page of theonline shop. ・ DFR chamber O-ring ¥ 864- / 1 piece ・ DFR chamber silencer gasket ¥ 540- / 1 piece Q16. Can individual parts of the chamber parts be ordered? A. All parts of Dogfight Racing products can be mail-ordered from one screw.
