Not a good afternoon . Ran into a big issue concerning the flywheel and stator assy . The flywheel locks up completely .The teeth from the outer edge of the flywheel are making contact with the cylinder assy . Looks like I'll have to find a stator and flywheel that will work with both the p200e and the stella's electrical system .

Crankcase is fully bolted up ! I got a lot of work done Saturday afternoon . Cylinder, piston and head are now installed . The rear brakes and rear hub are also now installed on the crankcase . Next on the to do list is the stator , flywheel and reinstalling the engine back onto the frame. Once that is done i'll attach the cables and wiring then put the carb on . I still need to drill 2 holes in the airfilter . More fun to come. The pictures below were taken as I worked away on the engine Saturday afternoon. They are not in any order .
Cheers !

Just another quick project update! Earlier today ( Wednesday) I finally started the teardown of the 150cc engine after I pulled it off the scoots frame . LUckily I am doing the dirty work at a friends place so I don't get into extremly hot h2o with the property manager where I live. I'll try and get some pics taken Thursday as I continue my work. After removing the cylinder and cylinderhead I found out that the crankshaft was shot ! The connecting rod was loose bigtime where it mounts into the crankshaft itself. It had too much free movement from side to side . It was why the engine was locking up ! Thursdays mission is to pull the flywheel off , remove the stator assy , split the crankcase without damaging it and then pull the efl driveshaft from the old crankcase . I still have to install 2 bearings and 1 bearing race on the new p200e crankshaft before I can start the final assembly phase of this project. More to come in the next day or two !

p.s. traitor to the gy6 scoot forum ?
Hell yes !
! Got to love those classy Italian Scoots !! ;D

Hi everyone ! Here is an update on my Vespa P200E engine build project . It has been a while since I last posted . Bit by bit the engine parts are being purchased . A new crankshaft is the last major item needed before I can start tearing into the Stella 2T 's 150cc engine . The Vespa Rally 200 , P200E and PX200 engines were the largest engines Paggio put in their 2 cycle scooters . The actuall stock engine displacement is at 198cc for a stock P200E . There are piston and cylinder upgrades to boost it to 215 cc . My engine will be pretty much a stock P200E but will use my Stella's updated electronic type ignition system and electrical system. Once all the needed parts are here I will be "canibalizing" my 2T engine for the EFL type gear stack-driveshaft assembly and reusing the flywheel and stator assembly . The Vespa and stella's newer stators have 2 different markings on the stator assembly to help with setting the right timing. On a GY6 you set the timing via the cam shaft and timing chain with the help of TDC , for the P(PX) 200 engines and on the newer P PX and Stella 2T engines TDC is critical . There are no timing chains and camshafts on a Vespa 2 cycle scooter engine. The picture I am attaching shows 2 markings on the lower left. one " I.T. "is for the 150 ( 18 degrees off tdc) and the P and PX 200 is the "A" ( 23 degrees). The line on the crankcase is the timing marks. The P and PX 150 and 200 engines timing can vary by 1 to 3 degrees depending if your using a reed valve and if your using a modified race type crankshaft or cylinder and piston . This is my most biggest concern at the moment when the engine is finally installed on my Stella's frame. I hope that will be by the end of the month if funds permit . I'll post again when that time is finally here hopefully with some pictures !! There are still 2 bearings to be installed into the crankcase and the bearing race to be installed onto the crankshaft. If all goes as planned (pending any serious issues once the engine is together ) I'll be back scooting by April . ;D
Cheers ! ,

P.S.The stock driveshaft for a P200E has a tendency sometimes to have the tranny jump out of gear when at high speed. The EFL type drive shaft found on the later PX series scoots took care of that issue !

Check the forums help section !! There are several different trouble shooting guides that may help you figure this out !!Vacume leak ?? Too much air ( carb mounting gasket not tightened down properly ? do you still have the stock airfilter installed ?
