Measuring your bikes DB's

How?..yeah i know....what i mean is i want to do a trackday or 2 on the smr, now it's noisy, Akra's, no sas and no db killers, the ecu is mapped so.

If i have to put the db's back in then i'll have to remap, so, in the real world what's the best way to test the DB's?

Help pls x :smile

your baffles in will not affect the ride ability of your bike.............it will be quieter and kill a few horses but i honestly doubt you will notice any power difference unless you rag the arse right off it.......................ive never had my bike checked at knockhill even though there is a max limit in place, all i have ever done is tick off a checklist stating my bike is sound and sign a discaimer:wink:

they did check

at Cadwell, at different revs for different engine types. They made some guy on  gungabike put steel wool in his can to quiet down. Didn't help, he ran off at the end of the start straight:biggrin:

cadwell...

before you book on to a track day and pay, go along to any of the others that MSV run and you can have it noise tested free of charge.. then youll know if your in the limit.. cadwell is 105Db at 5,500rpm, static test.....

dont know if "no limits" offer this facility.. might be worth checking depending on who you are bookin ya day with...

Good morning..

Ah ha, you wanna do a track day or two..... Keep me informed, I'll come n play.. :biggrin:

As for the map, no, putting the db killers in won't affect that. Even putting the standard pipes on (if you have them?) won't be bad for the bike, it just won't run at its optimate!

As for testing the db output you can use an app or tool aquired off the net and that will give you an idea but....... When you get to the track they will have their own people do the test (not part of the TDO crew) and some of them have no idea at all how to use the equipment! Sadly their word is law so if in doubt, don't bother booking a day unless its a 104/105db limit.

An idea could be to rock up at a few early season track days and ask if they'll test it for ya, but they don't have to! Be nice and they prob will tho! Maybe calling the TDO before hand to speak to them would be a good idea.

My guess is (judging by my Tuono's performance) that with baffles in you should be ok. Never had it tested tho!

Rockingham, Snetterton and Oulton will, in my experience, deffo test ya and if you pass the test with a baffle in they will mark your sticker such and they will look for said baffle as you go to enter track. They also have noise meters around the track and WILL black flag you!

Bear in mind tho that this is the tracks H&S people doing this because of the council and not the TDO's fault! If they had their way we would all run straight thro systems lol

As a note my GXSR600 blows 104db open, 102db with baffle #1 and 94db with baffle #2. Means I can use it anywhere tho #2 does restrict it a tad!....


Worth it tho for the fun :biggrin::biggrin::biggrin:

Cheers stealth mate

gunga want's to play anorl, so will let you know :smile

I don't get this db restriction malaky, if you don't like the sound of loud engines don't buy a house near a circuit, simples no? :blink:

My mother-in-law lives near a church and bells have been rung there for 500 years, yet people move to the area and complain about the sound of the bells FFS!, if ya that concerned about the sound, don't buy a house near a FCUKING CHURCH!

and relax......:biggrin:
