Sluggish bottom 09 TE450

Hey Guys, I own a 09 TE450 which has only been de restricted. It is an awesome bike but I was wondering if anyone else has any similiar problems with the bike bogging down and nearly stalling when trying to accelerate suddenly, mostly only in 1st gear. I presume the mapping is set up standard. The gearing is 13/47.
Any feedback would be great.

When you get around 500-600 mi on it have them adjust the FI. The critical adjustments are the Throttle Position Sensor and FB1 which will improve both low end and idle. After that I guess you can go to a Power Commander to customize your FI map and tweak it if it doesn't suit your needs.

Lots of owners are fiddling with iBeat and PC here so just search up the threads when you're ready.

HI Michael. I recently picked up a new 09 TE450 which is also derestricted. I've only done about 400 miles, but so far no sign of it bogging down or threatening to stall in any gear. My gearing is 14/47 to ease things a bit on the road as I have to do some road riding to get to the dirt, so you'd think that would make it more likely to bog down if anything.

I do have a G2 throttle cam though to calm things down as I was used to a WR250R before and I suspected there would soon be a man/machine/tree interface otherwise! Maybe that helps to avoid bogging down because you can't open the throttle as quickly from small openings?

Whatever the reasons I have to say so far it's been very impressive how well it does pick up from low revs, even when you're really in too high a gear and hit something unexpected.

Less impressed by the kick stand, but that's another story!

Sounds like good advice to get the FI adjusted once you've got some miles on it. Hope you enjoy yours as much as I do mine!
