Normal, Muffler Custom

[ezo]

Hello.　I am restoring a banshee in Japan.　I bought an FMF muffler the other day and am currently setting it up.　But I can't get the setting.

My hope is that I want to protect the engine, so it runs properly, but the plugs are a little black.

I've seen various people, but I wonder if the climate is different from Japan, or if the range of custom is different, or because the conditions are different.

All of my specifications are normal, except for the exhaust.　The current setting of the carburetor is No. 240 for the main and #25 for the pilot #25 Second from the top of the needle In this state, it rotates from low to medium speed without feeling caught. It has a decent amount of power, but it's not completely pretty, and it's a little dull.

The number 250 is even duller, and you can't find it even if you change the needle position or look for the right place with the pilot screw.　The burnt color of the plug is also black or white, and you cannot see the burnt color of the vest. The number 260 is too dull to turn cleanly.

If the air cleaner box is the same as standard, and only the muffler is changed to an outside such as FMF, what kind of setting is it?　The climate may be different, but I would like to refer to it, so I would appreciate it if you could tell me.　Thank you.

Elevation is more important.

Elevation and temperature are needed to help out with a starting point. Also when you say FMF muffler, are you referring to FMF expansion chamber pipes, or just the silencer?

開始点を決めるには、標高と温度が必要です。また、FMF マフラーとは、FMF 膨張室パイプのことですか、それともサイレンサーだけのことでしょうか?

In the area where I live, the average elevation is 93 meters and the minimum elevation is 2 meters

FMF Gold Series, FATTY Expansion Chamber (Chamber) and FMF Silencer (Turbine Core)

Have you done a leak down test?

Cylinders ported?

Fmf pipes are great. Every engine requires different tunes

Are you using original equipment jets and carbs?

リークダウンテストは実施しましたか?

シリンダーはポートされていますか?

FMF パイプは素晴らしいです。エンジンごとに異なるチューニングが必要です。

純正のジェットとキャブレターを使用していますか?

We don't do leakdown testing.　The cylinder is 350cc as it is stock.　With the stock carburetor, the main jet has now been changed from stock #200 to #240.　
Currently, the main jet #240 and the pilot jet remain standard, and it runs reasonably well in the fourth stage from the jet needle, but it is a little bobbly at the top revs.
However, I don't know if this is the original power of FMF.

i see you use google translate.

are you running FULL FMF exhaust system or stock pipes with fmf silencers (catback) 

i live at 150m altitude (acording to gps) i ran 200/210 jet and 25 pilot jet with stock pipe with fatboy 2 silencers 

now i have a full FMF exhaust system and i run 260 main jet and kept the 25 pilot jets runs good. bit rich at times depends on the weather i live in france and not close to the sea. at 20c sunny weather it runs great at 35c tempature sumer it ran rich so i had to give it more air (air screw on side of carb) but if it goes lower then 20c and colder air i need to give it less air cause it runs lean then (cold air is thinner so it get to much air)
