Hey guys I was just wondering if anyone knew when yoshimura would come out with a exhasut system for the raptor 700 and I was also wondering if anyone was using a Dobeck Performance TFI chip in their raptor 700 and how they like it ?

 

I'm waiting for the Yoshi to come out, haven't heard anything as of yet, give it a month of so, I'm sure it'll be out.

I've ordered the Power Comander III, more expensive but more advanced for fine tuning the EFI.

RaptorRandy27 has been using his PCIII for some time now with great results.

 

Im using the Dobeck and its great so far, i pulled the sparky out and the raptor started to run ruff and i would get some hesitation in the low rpms, now i installed the dobeck with there suggested settings and it runs great.

 

Did you disconnect the ground cable on the battery before you started it up after taking out the sparky and if not did you ride it long enough for the ECU to make the necessary changes? They say it should take 20 minutes of riding before the stock ECU makes the changes, I just find it hard to believe that this stock ECU can't handle just a sparky removal, if so, that's afully weak of Yamaha.

 

yes, i rode all day, and the stock ecu can only adjust for incoming air density, the computer has no way of knowing about the exhaust flow

 

I just took mine out for no more than a 3rd gear ride, in front of my house, didn't notice any hesitation through the gears or at low rpm and idle seemed same as stock, no roughness. My PCIII should be here within the week.

cool, i plan on getting a intake pretty soon and taking off my lid, im waiting for more pipes to come out and see how they stack up

 

Same here with the pipe, they should have something out in a month or so, atleast I would expect them to. I'll be waiting for the Yoshi myself.
