I am not sure how to respond to this post. I think if you actually read my posts to date I am pleased with the results so far. But to answer you question directly, why did you get on a bike in the first place? I understand this is a question to your question but think about it. Did you get on a bike because you always from childhood thought that motorcycles were appealing? Did you get on a bike because of the fuel economy? Did you get on a bike for the soul purpose of having the loudest bike around so everyone would look your way? I think the only answer to my question is you got on a bike because it was something you wanted to do, and that is my answer to your question. I don’t want to seem nasty but I really don’t care if it makes more power even though anyone who has any knowledge of FI knows that there are power gains, I really wanted to see if I could do it

Oi you!
Hand in you man badge now!
Oh the shame!





Excellent project.
Wish I had the ability to do it to my DR650.

You do, you might need to change the injector size and then get the right size throttle body. DONE!

I took the bike to work again today it is working well. I know I still have some tuning to do but I am very pleased so far. The bike definitely has a much better pull when you open the throttle riding a gear high. You really get to feel the torque the 350 has.

I have acquired a palm pilot for data logging. Tomorrow I will data log the ride to and from work and hope fully will be able to use that data in the tuning process.

I still have not used my wide band O2 set up. I would like to tune by feel and see what I can do before I use the wideband to autotune. I will have a file of both ways and it will be interesting to compare tune by feel and tune by technology.

I used the palm pilot to data log for a 25 minute ride but when I went to upload it I somehow crashed my palm pilot. I got it all working again and took a quick ride with the palm wire tied to the cross bar. The display on palm log shows real-time data on all the sensors. It verified my feeling that I was still rich, the O2 sensor indicated that. I will now lean it out some more and keep and eye on the O2 reading.

The best thing about this setup is instead of changing jets or clip positions you point and click. 30 seconds you can be out on the road or trail with a new “jetting” and you can have real time feed back.

I also forgot to post some pics. Here are a few. I am still wworking on detailing the write up in greter depth.

That looks great. I like your vibration isolated ECU mount (just kidding). Not that it's bad with a DR350, but have you noticed an increase in fuel economy?

The ECU is going to end up in a rear fender pack but for pure access I put it where it is for now. Too funny my first highway cruise the fender was going up and down to the point I might have a problem so I reached out and held it steady. To tell you the truth I have no idea on what I am getting for MPG's I removed the entire stock instrument cluster.

Right now I have it where it is very ridable and makes more power than carb, with no way to back it up other than feel, so I am very pleased. I need to work on the start up enrichments and acceleration enrichments.

I would just like to reiterate that unless you are not totally dedicated and willing to put some time in then this mod is not for you. I really enjoy having the 350 as a test bed for the FI conversion. I am looking forward to doing a pure motocross bike when the microsquirt is released.

I noticed your DR is an electric start, do you think it would be possible to add FI to a Kick start Bike?

Getting the right amount of fuel at the right time could make some huge improvments to how these old kickers start, or am i blowing smoke out my arse?!?!

[pookiebear]

I bet you could do the kickstart by using a NiCad battery to do the initial prime for the fuel pump and ecu start up. Even put a switch to put the battery in the circuit loop until it starts then flip the switch to take it out of the loop. Just better hope you don't walk out to a dead battery and not be home. Instead of Nicad you could use 4 D cell batteries then if it won't start just walk into the gas station and buy a few!
