That looks like it might be lean to me. I'd go up about 4 sizes and see if you can get a good ring down around the base of the porcelain to show up. Should be a 2mm tall darker ring. Some motors dont show a ring for a while till the plug is older. Some of the synthetic oils take longer too it seems. I like the cheaper oils to do chops. They show color better.

Too bad that thing is apart I prolly woulda payed you some difference and traded my cub motor for a 4 mil. If it was faster than my 392 cub that is. Finally got it done this week..it rips. LOL. Good luck iwth the sale.

I'd trade you if you were close. I've got 35mm keihins. Where you located. We'll be at L.S. Ok. next weekend.

Sold pending payment.

bump It's chromemoly and light not a cheap heavy swinger. Will take trade on somethin.

$200 shipped before it goes to ebay.

Mainjet fall out?

+8 Banshee, crush/oval tube, stock carrier style. Real nice, no bends etc. $220 I'll pay shipping to lower 48. Boxed up ready to go. This was a high $ swingarm new. I take paypal too. Thanks for looking Todd

A lot of bikes do it banshees are somewhat bad about it. Make sure your clutch lever and clutch adjustment is good. Check the lever/indicator on the cases under the left carb and make sure it lines up like it should.

Maybe I'm wrong but I believe you are wanting to figure your cranking compression to figure octane requirements, dome size requirements etc. You dont fill the bottom of the motor you fill the top above the piston. Slightly oil or grease the cylinders so the rings seal good and go to TDC and fill up the combustion chamber with oil till it fills right up to where the bottom of the sparkplug would be. Your motor has to be inclined so you dont have an airpocket in the head/combustion chamber. Measure the CCs of oil that filled it up then take the displacement of only the cylinder you are measuring so half the CCs of a banshee's 2 cylinders. Take the Displacement in CCs divided by the volume of oil it held. Example if it held 18 ccs of oil in one of the the combustion chambers and you have a 348ccs twin cylinder divided by 2 to only measure one cylinder = 174cc in one cylinder divided by the 18 ccs = 9.66.. to one compression. CCs of cyl / trapped volume = comp ratio - 1

Are you actually wanting the crankcase volume?Crankcase compression??? or are you wanting to get the uncorrected compression ratio of the combustion chambers?

I was thinkin a couple hundred $200 it's a high $ swinger new.

I have a +8 crush tube stock carrier type.

Stay stock ign, and spend the $25 it will cost for shipping and have Jeff at Fast, Nate Mcoy at Mccoy's , or K/T do your cylinders and it'll rip. Those 3 have done some of the fastest I know of and they held up well. All are helpful and will take care of you.

Zoops is whatcha need.

Sweet bike. I know lots of guys that run 33s to 39s with topend pipes,porting. I'd say if that's a bike for carving curves I'd stick a little smaller like 33/35 but if it's a bike you ride wide open a lot or drag a bunch then go 38/39. I know some seriously fast 421s and one of the fastest 7 mil cubs I know of with 35mm carbs. I like the snap and throttle response of the smaller carbs.

Pm sent back let me know if you want em. Just trying to pawn off some stuff that's sitting in my shelves. Still brand new.

Heres some pics. Just took em. Pic of my +8 I'm gonna take off too. http://i9.photobucket.com/albums/a52/Radar51/shanes-1.jpg

I have a new set of carbon tech carbon fiber reeds I'm not using still in the box. They are over $90 new. I'll let em go for $50 shipped. They work really well on you stock cages.

If the reeds are good and you are a light rider I have a really good Ohlins rear shock that'll work it's a 12" so it lowers a +6 probably 3". I need a set of vforces. I also have a brand new +6 swinger are you wanting to trade the reeds and a coolhead for one? Radar

If it runs good like that then go up on the mains till it runs like crap under a load in a higher gear then go down. The reasons bikes need bigger mains then what everybody else uses are, air leak in carb boots,intake,gaskets, base gaskets, and just the differences in each bike. Go up on the mains till it sputters under a load.

I dont like the DG aka Doller General pipes either but a friends old junky bike with them hauls azz for a stock mild ported cylinder,stock bored carbs and he weighs 300 lbs. I didnt know they only add 1 hp. Beats on lots of piped 450s at the dunes with em.

KC area but i know you go to the dunes. How much you wanting for it.

I'm interested I used to hurt myself all the time on one in the early 80s. The only bike in our family that hurt every member of our family. :biggrin: How much you want for it. I'd like a pic. pm for email if you cant post.

Nobody? Gonna have to order new ones I guess.
