Well here it is, my recently delivered (without keys) 2010 Vespa 300 Super in gloss black, it was a dealer re-crated bike and returned to PGA "as new". Since it came with no keys I currently have no way of knowing the exact mileage but the ECU, lockset, and good keyset I have are now off to the hacker's for code extraction, re-key-ing and cloning, I simply was not prepared to pay the asking price for a complete new ecu/lock set. My actual cost even as a dealer was still a rather offensive number.
She is a beauty, even if in that "diamond in the rough" sort of way. Obviously some body and paint work will be required as the project enters it's final phases but long before I worry about that I am certain some cutting and welding on the stock sheet metal will occur anyway. I asked for a damaged one, for cheap, and PGA delivered. I doubt it has more than 100 miles on it. I have been wanting to play seriously with an EFI 250-300 Vespa for a long time as most of you know but they only come and go as far as demo units and customer bikes so it is hard for me to learn things like "how long does it take for closed loop to learn a new config...etc...".
Gloss Black, like my heart and my Benz!
So this will be a different sort of project to make it have value to more Vespa/MP3/SC250-300 owners. I am not going straight to a big valve head, cam, and turbo, this will be done in bite sized little chunks.
Step 1: Make run as is, allow 600 miles for ecu to learn STFT and LTFT trims and then onto the dyno dead stock.
Step 2: My "Micah" airbox mod (with detailed pics) to see what exactly that gain, I have done the mod many times and know it works but have never been able to test that mod alone
Step 3: Pipe testing, I own both the Leo and Akro pipes
Step 4: Malossi head kit, probably not going to do the cam since the cam spec was not a huge difference between what I measured from a stock cam to the Malossi cam and posted in a previous thread.
I may have a change of heart about cam and piston I choose to use, the stock setup is perfect for boost, dished piston at .8mm squish
Step 5: Optional, possibly a Malossi cam and piston test
Step 6: Tuning, make this naturally aspirated version of the motor run as well as possible, this is a MUST since serious tuning will be required once we move onto "the final solution". I have both a way to manipulate the closed and open loop portion of the load range.
Step 7: Boost, either turbocharged or supercharged with an AMR 300/500 blower (it is called a Super after all). I love turbos because they use wasted energy to make more power and work perfect on a CVT equipped scooter, since you are always at 6k rpm or better there will be little lag really. Blowers however are friggin' awesome too, nothing beats 10-15 psi of boost from idle to redline....decisions that need not be made too rash! Once boosted in either manner a water/methanol system will be required for intercooling, as will some serious fuels testing.
Please add your thoughts, while this may be my project I want EVERYONE to learn as much as possible during the course of the event. If I have overlooked something of importance to you please comment in this thread and I will try to make it happen, or test it, and if you have advice I am always open to listening, not that I will take it BUT, I will listen and think on it!
Once power gets a little more serious than stock levels, injector testing and pump testing will be required as well, as well as a return to the older "return style" EFI system since I like my fuel nice and cool and constantly recirculated. I have several injectors to test but need the MP3 400cc injector and an MP3 500cc injector for this portion of the learning experience, if you have a spare sitting around (dirty is fine I have an injector cleaner) you are willing to donate you can find my shipping address all over this website!
If stock is about 14.5 bhp to the back tire, I am thinking 22 in naturally aspirated form would be a really strong goal and 32-34 under the added stress of boost would be just right to make the most fun Vespa EVER!!!
