The gasket for the gy6 b type engine with 16" wheels is different than other engines because of the stud spacing and the 2 bolt valve cover. It does take a 57mm piston.
I tried the gasket on both sides too, that is why i attempted to use old metal gasket.
I think i just have to get the gasket from bms because i cannot verify that the ebay gasket will work.
If anyone has replaced this gasket for a B type engine, let me know where you found it.
Thanks again

Ok, thanks.
Does it need anything to help it seal?
I read someone used copper spray on stuff with the metal gasket.

I know it was not lean, everytime i checked the plug it was dry black... maybe it became lean at some point... but not sure what would cause the change.
How is the efi kit working for you? Also what type of pod filter?
I'm debating on what filter to put on it, or just go back to stock.

Jeepsteve- do you have the original air box or a uni filter? I wonder if bits of my uni filter caused the white valve. I have clesned it and re-oiled it, but it looks like it is deteriorating. I'm going to replace it with the dual stage uni and see how that holds up. I am at 4800 or so on the odometer. I have 108 jet and the original 35 jet I was blessed when my wife found this scoot for $600 brand new when tank was about to go out of business. I don't mind that i had to tear it down and learn how it works  |

I got the whole thing put back together today!
One main issue was that the new head had a different angle for exhaust, so i had local shop cut and weld flange to the new angle on head.
Things i changed:
Crankshaft and seals
Piston and rings...just in case
New head
Cam chain tensioner
Exhaust gasket
And necessary gaskets for 57mm piston gy6b
Took it for a short test ride and all is well so far.
Thanks to everyone here and to bluefronts former posts on scootdawg

You can get the samsung tab galaxy 2 for around $150 at costco...they have had coupons.
You can also get deals on groupon.
I would say the bigger name brands are just better quality. If you want simple get an apple product, but if you like to play and customize things an android tablet is better.

I had time to finish taking the engine apart and found that the crankshaft did have some play in the bearing on the cvt side.
Does anyone know where to get a replacement bearing set?
I have seen a crankshaft on scrappydog's website, but i wanted to know if there are any other options?
Also, has anyone ever had the valves turn white like the above pic?
I'm going to change the head... but curious what might cause that.
Thanks

I took apart the head and this is what i found... I'm assuming ther valve shouldn't look like this. Do i need to get a new head?   |

[replyingto=t150]T150[/replyingto]I was able to get the muffler loose after wiggling it for about 20 min. in different directions.
When i took off the muffler i did not see any gasket... interesting.
I now have the engine out and just need to get the rear tire off.
How do i know what gasket set size to order? I have seen several sizes available.

Yes, took off everything and the whole muffler is loose but it will not come loose from the studs on the engine... i cant figure out what is holding it.

I finally had some time to start taking out the engine.
I was able to take off the exhaust nuts and bolts, but i am having trouble getting the exhaust to come off of the studs. It can move around but will not drop down from under the engine. It seems like it should drop down easily but it doesn't.
Any suggestions on how to remove it without damaging the studs?

I took it out for a few test rides and i can still hear a constant noise coming from crankshaft area. I even bought a mechanics stethoscope to verify where the noise is.
I'm going too have to pull the engine.
Has anyone used a bearing puller from harbor freight to remove the starter gear behind variator? They have a cheap one for 16.99... Or do i need a gear puller?
Any advise on where to look for torque specs?

[replyingto=jeepsteve92xj]jeepsteve92xj[/replyingto]I'm trying to track down a noise coming from inside engine... i thought it might be a crankshaft bearing, that is why i needed a flywheel puller.
I took it out for a test ride and i can still hear a noise and it also feels like something is going to break from vibrations. I have already inspected/ changed everything in cvt so i can rule that area out.
I guess i might have to pull the engine to track down the noise... the strange part is that it has great acceleration.
