Well its fixed. I found a replacement seal at Autozone. It is actually a timing cover seal off of a 1993 Geo Storm. worked perfect. No more smoke.

Gearbox side

I am trying to find a seal that I could drive and pickup tonight or tomorrow morning. 2004 yamaha blaster

Ok is the gearbox breather tube the little nipple sort of under the carb area on the right side if the engine pointing straight up with a hose that goes up and under the front hood. I thought this was the crankcase vent hose. When I did the leak test I couldn't build pressure unless I put my...

I built a leak tester last week. How do I pinpoint the leak being the crank seal.

I have a 2004 blaster that I bought 2 weeks ago. It was blowing quite a bit of smoke when I bought it but the guy said it was newly rebuilt and he was mixing the oil a little rich. Since then I have ridden it probably about 12 hours and I am using yama lube 2 stroke oil mixing it 32:1. It still...

I just ordered a carb rebuild kit because my float needle is leaking which causes the carb to have a constant drip. I was wondering with my current set up, would it hurt in any way to go back to the stock main jet since it comes in the rebuild kit. Right now only difference from stock is the...

This is what the one on ebay looks like.

You can see the bolt in mine.

What does the fitting on top of the carb intake boot go to? I found one on ebay with a hose and a canister of some sort. Mine is currently just plugged with a bolt.

Well i cut two gaskets out of some gasket material and then put a thin coat of RTV on both sides of gaskets. Bolted it all together last night and I let it cure all night until about 11:00 this morning. It fired right up and runs way better then it did. I extremely impressed with the piece I...

Well this is what it looks like now. I had to make my own. School is cancelled tomorrow because it is supposed to snow and I really want to drive it in the snow.

Ok is this what the reed cage should look like. It doesn't really have enough of a lip to catch on the engine block. From pictures I see on the internet all I see are cages with flanges with screw holes.

Ok I did some research and am heading to home depot after class today to build a pressure tester. I looked at piston and cylinder walls through the exhaust hole and it had a few lines on skirt but piston looks great and cylinder walls look great too. So I'm hoping I have an air leak somewhere...

Ok now that I know where to look for air leaks, how exactly do I test for them?

Where could the air leaks be?

Once it's running it would idle all day long and as long as your in the power ban it will haul butt. Crazy fast.

Not what could have happened. I bought it because he said the top end had just been rebuilt and it just finished breaking in. When I bought it Saturday it would crank like 2 or 3rd kick. It was in the 50's outside then and now its in the 30's. I drove it about 4 or 5 hours sunday and used 93...

Ok since the carb was off and I know its not putting any fuel/oil mixture into the engine so I put a couple squirts of oil in the cylinder. I kicked it about 10 times until the needle stopped moving. It got up to about 110 this time.
