310TE Noise killer

[vetsku]

I have some questions from 310TE:

1) Does anyone know how to modify the noise killer (I have uncorked bike). I modified noise killer to 120mm long and drilled 8 pcs 8 mm holes and after that the bike had more power but it had some short “black outs” from full speed, and I think it comes because off modifying. I think that efi should also adjust after modifying the noise killer?

2) Should the breather pipe from cylinder head routine out of intake channel for more power?

I do not think the EFI will adjust to your changes unless the o2 sensor is still hooked up.

Once mapped/baselined, I dont think the O2 sensor does any adjusting.............but I could be wrong.

Someone please correct if I am wrong

based on the thread- Ibeat Specifics on TT- the lamba sensor works off the same map as the in open loop (lamda removed/or "race mode") It leans the mixture apparently and does not enrichen AF ratio~ and only effects under certain circumstances.

So if you make big changes to "open" your bike up than you probably will have to take it to the dealer and have them change settings- or adjust with a Power Commander- But thats just my interpretation from reading about this since I am trying to learn about efi too- new to me- so far so good.

Great site Rick****************************************! thank you

Thank you- I never saw that= I will add that to the list of things to get. I don't know what my 09te450 would sound test at with the Sparky- but it seems barky for dual sport events. Our club does sound testing- 96 max- we are educating and trying to promote the sport. Main thing is to keep the power down in public/less remote areas. This thing gives me some options... I will test them both. For closed course and enduro's the stock sparky will work fine.

my take on these as of today....
1. you may have to have efi tuned, results vary, it should vary to a degree but.... pick how you are generally going to run it (mods) and have ibeat tuned and or get a power commander if its state of tune is not good enough.

2. Do not mess with the breather pipe- a. it has to breath b. you don't want it to breath dirt, I have not seen how mine is hooked up yet but generally don't make changes there. Gains by modification/ venting are debatable. There are some that find alternate methods often best left on pavement or sm.

if you really want to find gains- get a power commander and take it to a good tech with a dyno****************************************

Hi,

without the European db-eater the bike is to loud and also starting is not perfect. What I do is hancraft a metal ring like the US-spark arrestor for a little bit more back pressure. Hope to get near the power of my perfect jetted Yam WR250F with full Akrapovic 94dB exhaust.
