So I should have a few bores left
Yeah all the way up to 89.5
its a 250. the piston is a 68.50mm
Hes got one bore left. Call Cometic and order an oversize (big bore) gasket for a 87-92 LT 250.
Oh man .... Where are my glasses!
Geeze
What will the big bore kit do for me
Some say more power. But not much.
Good porting and pipe combo is better than a normal big bore kit.
That, and give you head gasket problems.
Get you a set vforce 2 or 3 s and Scp pipe and some porting you have a strong lt250r. Hey what brand of headgasket are you using i dont think this question was asked.
Get the cometics and save yourself a lot of trouble.
www.cometic.comOr Mitch might have some in the store section, not sure if he carried 250 gaskets though.
So u think I need bigger head gaskit
I still have to so a few test that were posted a few post ago

Have you ever tried to read your own post?
I use oem gaskets. They are already made for the last bore so you can use them on 67mm or 69mm with no problems.
Had a friend come by and check this motor out for me me is a 2 stroke guy he took some measure ments he said that with the cly has to come up about .80 to make it stop hitting the head that's about 4 base gaskits is that ok don't sound ok to me
i wouldnt do it. Just get a thicker head gasket or custom dome made. stacking gaskets will off set port timing.
What if the cylinder has been decked that much? That many base gaskets would put the timing back where it's supposed to be. Anyone got port timing for the 250?
I asked him he said my port timing should be dead on I called cometic they said they could make me a spacer in stead stacking gaskits

.80 mm is about 1 1/2 base gaskets. .080 inches is about 4 base gaskets.
What did your engine builder do to your engine when he worked on it. Why would he machine the head gasket surface or base gasket surface that much?
Did he put a stroker crank in it?

I think I smell a rat.
Talk to your builder and find out what he did to your engine and WHY !!!!!!!!!
I
Sounds like Darahji's builder made it over to the States.. Bubble gum and super glue, makes for the bestest epoxy ever!
He did not stroke it i bought this quad the motor was in a box I had it bored and new crank that was it so I don't no y it's so far off
thats unfortunate. probably why the motor was in a box when you got it.
Iam sure lol but I now have a lot of time in this quad so iam sure it will all work out
1. Get a die grinder.
2. Push piston to TDC.
3. Grind until nothing hits.
4. ??????
5. PROFIT.
