I have the typical ‘no start’ problem on my Ditech. Changed the coil, lead and cap, plug. Removed and tested injector, stator is producing power, fuel pump fine....Compression 75psi but I’ve read on Aprilia forums that it should be between 90-110.. and people who have 130...
@@petesgarage4670 hi, update, so installed new rings and gaskets and the motor still had 75psi. It actually started and ran for 5 minutes then lost power and died. Doesn’t start anymore. Where could the motor be losing the compression other than cylinder/motor cylinder/head or sparkplug.. if the injection system has lost seal, then it’s time to bin the bike without spending lots of money for those parts.
@@AutoClayis the teflon gasket and the other 2 rubber gaskets on the blue injector ok? did you check it? the only thing I can think of is a crack in the motor casing. there is no other way to loose copression.

I own a piaggio purejet 2006 injection. Starting fine, runs fine, pulls great until it hits the operating temperature. After that it splutters hard between 6500 -7000rpm and it loses power. If i give wot it doesn't splutter anymore and the overall performance is lower. used different sparkplugs, water trap, semisynt oil, cleaned everything, compressor it seems that is doin 4.5 bar very fast. Didn't do compression test and now I got the rebuild kit for injectors. Any oppinion?
My ditech will start and will idle for a while and then we'll just die out. I can turn the throttle and can visibly see the rear wheel spinning, but after a while like five minutes or so it will just stop. Was wondering what things I can rule out. It is a 2003 Tuono ditech. I can take a video. Al's I line in USA. Is there a good place to get the clear tube that goes from the 2stroke oil pump to the manifold? Thanks.
a lot of things can cause this problem. Faulty fuel pump, faulty spark plug, injection clogged, faulty electric throttle sensor..... what I would do first: take out the spark plug and inspect it. Let me know how it looks like
