Nice cant wait to see everything!

ok i have not done much on the installation but i do have my switch wire for the power to the ecu ran i tap in behind the main switch found the wire that turns hot when the switch is on and peeled back a little of the insalation and wrap the wire around it and soldier it good and then cover with electrical tape good and solid the wire i ruan it to under the seat where i will place the ecu so now all that i need to do is make the connection the feul tank is great for this install as it has a line that goes to the petcock and it has a return line from the petcock

Glad things are progressing!

If you have specific questions, PM me or email me as I may miss them in the thread.

I found a new throttle cable online since the one I "fabbed" fell apart. Hmm, Matt told me he was going to include the option for the right size throttle cable. Guess he hadn't thought about the 150ccs. Anyway, glad you're still progressing!

greg check earlier pics in this thread i made a bracket for the mount off a spare carb and piece of metal strap so i do not need to modify the cable

well today was nice pretty day so guess what i started installing all the parts on the scoot pulled the gas tank and carb lower panels got it down far enough to get to ever thing while i was there i pulled the valve cover check the gaps found the exhaust tight so adjusted them so they are right found the air box split wide open around the seam fix it cleaned the ground point put much heaver ground cable from the motor to the frame heaver neg. cables to the battery figure that i can connect the power and ground for the ecu at the starter relay and ground point so i don't have a ton of wires hook at the battery just to make things look better under the seat here are some pics of what i done today i still have 3 wires to hook up and put the battery back in

OK today i went out and finish off the install turn the switch on and let the fuel pump cycle a couple times and try to start it next thing i know it is running with the efi system installed it like a totally def. bike before i barely got it past 45 on the chino meter now it pushing 65 on it and still wants more i am very happy with the system i still need to fine tune things but all i see is a big gain in power and speed i now thinking i can take this bike for those long country rides like i hope to

Great, sounds like you have it under control. 45 to 65 is a huge increase in power, almost double in my estimation. john

yea that was a big surprize to me i knew there was gonna be some improvement but wow i also know i will have to upgrade the charging system as the power draw is a little to much but i had some fun running around town today and passing cars that i would have never been able to before

Just as long as the valves are adjusted , you will just poke the starter switch to get it started . How is it to kick it started ? Time for charging system upgrade!!!! its nice and jerkey with fuel injection . the very moment the tps senses movement the injector responds , so does the timing . Others will chime in on how great or how much they like carbs , fuel injection is the move . I have a 250 vespa with FI I was thinking of using the injection system you are using , I can play with the mapping .

oh it is sweet to kick start this thing now i dont even get thought the full stroke and it is running until i can afford the parts to upgrade the charging system i will need to pull the battery and give it a charge i have leds order for the taillights and just got the leds for the dash just waiting for the package to get here from Hong Kong

[tvnacman]

don't use the electric starter !!!!!!!
pull the headlight bulbs so conserve power , Just be extra carefull !!!!

Just as I figured. Glad it is working so well. Have you thought of finding a way to modify the battery box so you can use a small lawn tractor battery with a battery maintainer as a cheap way to give you enough electricity to allow you to go about anywhere you want to go in the daytime.
EFI makes the 150 come alive!!!

[justbuggin2]

the battery is under the seat in the bucket i have the box for it out right now as the mounts that hold it to the side is broken i have a solar battery charger for a car that i am thinking of mounting behind the windscreen as it does not get in the way of my view of the road and that way when i am off the bike it will auto charge the battery

and Yes the efi has woke the beast within this bike i had no idea that this bike could go so fast i have pegged the needle on the chino meter a couple times now and WOW great throttle responce and plenty of power to spare
