No i didnt ask, i assumed just like you that a BB sleeve kit should be a 240 with some thickness for more bores. like a stock sleeve.
And youre right about the shipping$$
Dont worry this work is way over my head, ill just do the part you said ...crack a beer and wait for the cylinder to cool down to room temp
Good write up O'Connor! You beat me to it.
Azores,
What you have is called a "thick" sleeve. They are built that way so one sleeve part number can service a wider variety of applications, it keeps tooling costs down for the sleeve manufacturer and in the end parts costs down for the consumer. That is a good quality sleeve and piston. The piston is Teflon coated for wear resistance during break in and boost ported. I actually like this piston design better than the 72mm Wiseco's that were sent with this kit in the past. And as O'Connor said, every sleeve has to be bored to fit the piston. And as a note for future consumers, I don't recommend a sleeve job as an upgrade to a serviceable stock cylinder...It in my opinion is a viable option if you are on your last bore and the cylinder is otherwise garbage.

Me to bro, i just learn it the hard way.
This is going to take some work but at least i have a spare cylinder and head, so ill work that one and when its done (if everything goes well)ill replace the my current top end and this way ill have two runing engines.
I apreciate Oconnor´s help and thank for youre words to Wildcard, i feel a lot better knowing this aint a crapy kit.
HMG i just realized i got the winter rebuild flu that some you guys are talking about... lol
I will have some updates on a near future... Have to install a 4+mm hotrod crank, new seals and berings, work that 240 kit, find a boot for a 38mm pwk, try to tune that 38pwk, and some other small things.
Just installed a new Procurcuit 304, looks great and best of all no mods needed to fit the B1 pipe i have

This is the same boot that i am running with my 36mm, it is a nice boot.
they are out of Ohio.
Ebay is runing low on boots, have to wait, just not shore the 36mm boot will fit my 38pwk, anyway im gona try a boot from a Ktm250exc, i think ill only have to fill in 2 holes and make 2 new ones... easy task
I know this is a very old thread but I ran across some interesting info yesterday. At present, LA Sleeve only offers 3 different sleeves for Blasters and Wiseco only offers one. They may have had more in the past. Could be another company like Advanced, who knows.
Part number YA-5035 is for a standard bore and can be bored to 68.25 mm.
Part number YA-5035H is a heavy duty sleeve that's used to repair cylinders with broken skirts and can only be bored out to 68.25 mm as well.
Part number YA-5035B is the big bore sleeve. It's inside diameter is about .035” smaller than the 72mm piston.
You may have gotten the YA-5035H sleeve. If you did, you can't run the 72MM piston as the cylinder sleeve is made to repair the stock bore. This is what LA Sleeve advises.
I found a site advertising the same type of claim and they state it's the heavy duty sleeve to repair broken skirts or bore to 240 but no mention of part numbers. I sent him e-mail and asked what the number is. We'll see what he says.

Blasterazores,
Was the sleeve ever installed?

i dont know the part numbers or who makes them but i think its advanced sleeve makes thick sleeves for banshee and blasters,its basically a very think sleeve that has a stock bore as the first bore but can be bored all the way to the 72mm big bore. i know for a fact that some banshee sleeved are like that. another thing is that a dt200 as you may know is bascially a water cooled blaster enging that was in a street bike. the cylinders on the dt200 start at 66mm(same as blasters) and finish at 73mm, same stroke and pin height as a blaster but the wrist pin is narrower but still 16mm pin. ive ran the wossner dt200 72mm piston before just had to machine the inside so the standard wrist pin bearings fit, it also will not have anywindows in them, i machined them in as well similar to the piston that blasterazores got. so i think its the "thick" sleeve, if they gave you a 72mm piston after installing the sleeve alot of usable bores will be bored out to get you to 72mm.
Ya Bro, got everything installed... (240 sleeve / 4mm crank / 38mm keihin carb) Blaster is riping now... totally diferent machine.
Thanks people.
this is not correct, the DT cant have a 72mm and up big bore piston unless you pin off the powervalve
the larger piston will actually hit the powervalve at a certain RPM
I have an 05 blaster bored to a 240 and it runs awesome. But the cylinder was done I didn't get the Vito setup. I'd ship old cylinder off and have it done the performance from stock to what I have now is a huge difference.This is what came in it.
A shop will only charge you 60-100$ to do your cylinder. I think you'll like it better then Vito big bore kit. I'll get some pics today we have 3 blasters. All have different setups. You'll enjoy the power difference for sure.
