DT/MX Re-sleeving sleeves

[cyclegod]

My MX250 barrel needs a rebore to take it to 1.5mm over, and with only one rebore remaining I got to thinking, can I pull the sleeve out of a standard bore DT250 barrel cut/grind the ports to match my MX sleeve (which has pretty much got standard porting) and bung it back into the MX barrel ?
Or would I be better off just porting the DT barrel instead ?

I do like to keep the genuine MX stuff on the bike though

why dont you just get a new sleeve fitted ? they are still avaiable we just put on into a 74 mx 250 after a pop rivit from the air box desided it wanted to lock itself between the piston and bore for a while until it total grovved it to the point it couldnt be honed out so to speak.

Why not post pics of the 2 barrels cyclegod?
Usually the trailie barrels can be taken to a higher spec than the mx versions as the ports are tiny in the trailie and this allows different port timings and shapes.
As for the resleeve anyone with a press and an oven can do it.

there in the book.  any engineers can order youone in, wisco and some other do them as standard.  ill get a part number and price if i remember, im at the track on Sat so if i see the info ill remember to bring it home with me.

like lozza said if they have an oven they will be able to order one in, dont waste you time in trying to remove and old one and trying to refit it in another old one then you ll have 2 shit ones.

ok it was an LA sleeve and the cost was retailed out at about $300, not sure what it was direct probly half that.  LAst time i looked it was these guys or NOS only, didnt turn up any other makers last time.

The part number in the book is YA 658SL ,

i think this is the web site just send them an email asking what they can do one for trade etc. 

http://www.lasleeve.com/master.html if you go to a serco reseller they will have this in their catalouge as it also cover the wisco pistong for it etc.

Although its for the 73-74 MX 250 it also Funnily enough iafter the product code the numbers 1976-79E

im wondering if the 76-79 YZ E uses the same sleeves ? you might find one of those on the shelf in Au already ?  up to you dude above is all the infor you need to get going :O)


see how you go.
