Picked up a 2008 leftover te450. I have two questions...

One, the bike runs hot. I feel as if it's corked up pretty bad. I am thinking about gutting the stock silencer. It's stainless and can be welded back but it will require some time and energy. Has anyone else done this? If so pics and link to discussion thread please. Again, this is a te450 and it's not riveted closed. I plan to make the pipe shorter as well. The grenade launcher look does nothing for me.

Second, I took the throttle stop off, screen from behind the air filter out... I need to get my hands on a o2 mid pipe plug and that wire thing that goes into my ecu? It's in all the power up kits. Does anyone have an extra setup or know where these can be bought, as I don't want the entire power up kit just these pieces? Does the bike need to be re mapped with this type of mod?

I can't answer the F/I related questions as I have a carb'd bike but:

1) Refit the mesh backfire screen. It does a pretty important job (or two).

2) If the bike's running hot look for obvious causes first.

3) Stock bikes aren't that "plugged up". A lot of people fit dB Killers with no detriment.

My advice would be to get everything running cool and sweet in stock trim as a baseline reference before modding. If it's running at less than 100% health then cutting stuff about will likely make problems worse.

There's a lot of knowledgeable owners here, I'm sure someone will be along soon to help with your specifics.

Edit: and if the dealer you got it from is worth his salt then he'll get it running right for you. Then you can start tweaking!

Screen is gone along with the carbon canister, power up kit installed with no mapping... runs great... little soft and needs a bit more punch on the low end in the dirt, maybe drop the front sprocket a tooth...

I went to a 50 tooth on the rear of my '08 TE 450. In order to get to the race map you have to have the O2 sensor plugged. You need to get someone to hook it up to Ibeat though and set up the FI. Mine was very lean on the bottom end and had the random stall. Once it was tuned with Ibeat software it is right on the money.
