Hello, on my Ditech Morini air injector is damaged. O-rings and teflon ring are very bad - PHOTO A . I found new injector to buy - PHOTO B . Seller say it is same injector , only look little different ! What you think ,I am not sure is it 100% compatible injector or not ?

B is old style SR injector .........(01-02)

-Will work/fit in any injector head on any injection scoot

The B injector is made of metal. It is very though after. I have read in this thread that it is more durable than the new plastic injectors.

-Because the bigger diameter of 'B' type it seals perfect on the O-rings ,and with less chance you blow a ring

-'B' type is pointed as '2 stroke purposse' where 'A' type is 'all purposse'

In translation - "B" air injector is better ?
Can I use same cylinder head and Inlet valve for both injectors ?
PS: What you think ,is it enough only to change O-rings on my old injector "A" or must buy new. I dont know is it ok,because he have scratches on metal ....

-The 'B' type injector fits both without any problem


THIS (http://www.apriliaforum.com/forums/attachment.php?attachmentid=80046&stc=1&d=1205792296) sucks ....

-Try to fix it back in .........(with use loctide or pruduct like that)

Thanks MAX ,2 type`s Cylinderheads and 2 type`s Airinjectors . But how many type`s of injection body`s have ??? Is it all body`s compatible with both air injectors and both cylinderheads ?
Is it same number O-rings for all body`s ?
Look photo... all 3 are diferent !
No. 1 is my ,is it compatible for A and B air injector ?
/ I dont know what is default ,because I dont know what are former owners change on my ditech :( /

Is it all body`s compatible with both air injectors and both cylinderheads ?Yes it is .........but on a BLACK injector there is more 'surface' for a better sealing



Is it same number O-rings for all body`s ?I think; type 1 > 13 x2,5 and type 2/3 are 17x3,5


Look photo... all 3 are diferent !Am I correct that type 2 is alu-cast instead of plastic ?


No. 1 is my ,is it compatible for A and B air injector ?Yes

Edit max>

At the bottom (bowl/pressure regulator) its possibel you again will find at least 3 types of fitment

MORINI DITECH :

CYLINDERSHEAD - 2 types
INLET VALVE - same for all bodys
BLOW/PRESURE REGULATOR - 3 types
INJECTION BODY - 3 types
AIR INJECTOR - 2 types

1,2 - always same
3- I DONT KNOW what is this ????
4,5 - I dot know is it same forr all ?
( `4` go upper plastic ring ,not like on picture )
6,7,8 - always same
9 and 14 - 2 size - 13x2,5 and 17x3,5
10 - same
11 - same
12- same
13 - same
15 - 2 types

You can combine any BODY`s with any AIR INJECTORS AND any CYLINDERHEADS ,difference is only in some O-rings .

MAX please correct me where I am wrong.

Part 10 is only found on a small nr of models (and works also without it)

Part 9 > 2 differend types > Black injector can handel both

Injector body > 3 types ( as far as I know 2 plastic,1 alu-cast)

The bowl (pointed as blow/regulator) > 2 stock types ............(and 1 polini)





1,2 - always same
YES

3- I DONT KNOW what is this ????
MEATAL RING AROUND THE INJECTOR

4,5 - I dot know is it same forr all ?
( `4` go upper plastic ring ,not like on picture )
SAME

6,7,8 - always same
YES

9 and 14 - 2 size - 13x2,5 and 17x3,5
YES

10 - same
ONLY FOUND ON A FEW MODELS (I think they where used along with type 3 body)

11 - same
12- same
13 - same
YES

15 - 2 types
(I THINK) always the same ......but not that important


You can combine any BODY`s with any AIR INJECTORS difference is only in some O-rings .Because body's 2/3 uses bigger diameter O ring ,I found they work better with BLACK air injector

-Using bodytype 2/3 on a small (bleu/red) injector gives more chance to blow the ring







>>>

IF you could make a chooise ,.....I would prefer :
> 01 type cylinderhead (http://crew.scooter-freaks.nl/john/kop%2001.jpg)
> Alu-cast body (2) (http://www.apriliaforum.com/forums/attachment.php?attachmentid=80215&stc=1&d=1205952129)
> Black injector (http://www.apriliaforum.com/forums/attachment.php?attachmentid=79961&stc=1&d=1205692217)

Easyparts hold a compleet O-ring kit but the teflon ring is sold appart from it

Hi MAX ,please help again !!!!!!!!
I buy new air injection,but with only one O-ring . I found new ring - but is it little larger ( and more fat) .
Seller say -it`s OK ,you can use that ring between Airi injetion and cylinder head.
That larger O-ring many people use when put Polini 70 cc . Larger O-ring is 100% compatible and hi can brook larger presure .
Can I use him ,or I must found other new O-ring like my old ????
