KEVSWS6

True not the same series we run on ours.

They work great, best front end combo I have been on. Its on 450 spindles and arms with a +2 over shocks eye to eye. It has some travel with the 22 inch tires.

Those cubs love lots of fuel and air.

No dont put covers on them. Hides the beauty. We run them on our 421 cub.

Everything leaks without a gasket or sealer. The sling shot goes under the stock cover. Once the stock cover is lightly modified you never have to mess with it again. The sling shot is small, light and stealth. It is the best design on the market. You can spend big money, have a tumor growing from your case and increase you rotating mass but that's not me.

I have a few in stock. They work great on our bikes. Have one on a 4 and one on a 10 mil cub both ported and make real power. Also know a few on here that drag race with them and they have no problems with them. I wont build a bike without one now. Kevin www.herrjugsracing.com

Glad your having fun with it!

A lot of blood sweat and tears in those pictures. Looks great. You must be single to be able to assemble a motor in the living area.

The PSI gauge has its place but when your drag racing you should be using this with it. The "Uncorrected Method" (sometimes referred to as the Geometric or European method) which compares the volume above the piston at Bottom Dead Center (BDC) to the volume above the piston at exact Top Dead Center (TDC). How to calculate? Quite simply, it is (volume of cylinder at BDC + volume of combustion chamber at TDC) divided by (volume of combustion chamber at TDC). The volume of the cylinder is easy....... (radius of bore in millimeters) X (radius of bore in millimeters) X (3.14159) X (stroke in millimeters). Then divide your answer by 1000 to get the cylinder volume in cc's. To check the "Flat Plated Volume" (FPV) of the combustion chamber, start by scraping the head gasket surface clean of gasket material, cleaning the combustion chamber of excess carbon deposits and the like (gently with a wire brush) and installing the normally used spark plug. Position some wood or similar supports under the head so that it is combustion chamber up on a bench with a slight tilt in one direction referencing the gasket surface (not level). Apply a narrow border of grease about 3 mm's from the edge of the combustion chamber totally encircling it on the gasket surface. Using a piece of plexiglass (should be round and big enough to totally cover up the combustion chamber, at least 1/4" thick or more) with a 3/8" "fill" hole in it at one edge, position the hole at the "high" side of the tilted combustion chamber and press it firmly against the gasket surface smashing the grease and creating a seal. Make sure to press it firmly so the grease does not become a spacer. Now carefully fill the chamber with Marvel Mystery oil from your burette again noting the beginning reading so you'll know how much has been used to fill the chamber after your done. Write your reading down. This is your chamber's FPV. To figure out the "Head Gasket Volume" (HGV) simply use the same formula as you used up above to figure out the cylinder volume, just substitute the radius of the head gasket ID (usually BIGGER than the bore, so measure it!) and use the thickness of the gasket (preferably the compressed thickness from a used head gasket) as a substitute in the above equation for "stroke". Divide your answer as before by 1000 and you'll have the HGV. Write this down also. The "Deck Height Volume" (DHV) is again calculated using the same basic formula. But you must either note the Deck Height during disassembly or put the piston temporarily back on the rod, slide the cylinder down over the piston (onto a fresh base gasket but you don't need rings) and use a couple of head or base nuts to pull it down firmly against the cases. Bring the piston up to TDC and use the depth measuring probe from a vernier or dial type caliper to determine how much below or above the top of the cylinder the piston crown edge is. VERY IMPORTANT! Check it inline with the wrist pin so the piston will not tilt on its' wrist pin axis during measurement. In the formula, use bore size again and substitute the deck height for the stroke. If the deck height was ABOVE the cylinder at TDC, put a negative sign (-) in front of your calculated answer. If the deck height was BELOW the top of the cylinder at TDC, leave the calculated answer as is (positive). Record this number as DHV. To determine the "Piston Crown Displacement Volume", (PCDV) On Banshees just use 7cc's Example: The dome volume of Banshee piston is approx 7cc (6.5cc)The cylinder vol is 184.745cc on a 66mm boreThe head vol is 15cc (with a 15cc dome).So, if you take the cyl vol + the head vol - crown vol you get 192.745cc.. This is your full stroke volume of the cylinder and the head, taking into consideration the piston volume.OK... So you need to figure the trapped volume .. The trapped volume is the actual volume present when the piston is at TDC. So.. this would be the 15cc (head) - the 7cc (piston)so 15 - 7 = 8cc Trapped volume....So now it becomes a simple ratio.. The total cylinder volume / the trapped volume so.. 192.745 / 8 = 24.093 = compression ratio of 24.1:1 I might not be dead on with some of this but it gets you in the ball park. I did not write this but save good info and post it for others.

I must admit I thought about keeping that bike. I love the Yamaha graphics and colors on that bike.

The trail port on those cylinders are not your typical industry trail port. Those are fully ported aggressive trail port cylinders. Made more for dual purpose. Set at 192 on the exhaust and 130 on the transfers with full transfer tunnel hogging. I wouldn't go over 33s on the carbs.

Good deal you should have some fun with them. If you have any questions on how to set them up let me know.

No really kadillacman could use them. If you have some jugs that are ported better and are faster for cheaper he will take them. If you know of any post them up he would like them as soon as possible.

Sorry these both sold.

Stock a-arm frame needed

This stuff works good. I have used it many times.

Yeah right. You see how I roll. Low budget. Wife got......cough....life got to me a long time ago.

What the hell is wrong with you?

That would also be good. Even the guys I work with said get rid of the toon girl.

I like this one better. Take the chick out and the motor out. Center Tims bike. That should do it. How do you know I didnt build Tims motor? No your right he couldnt handle it.

Butch this guy needs help...Randy......where you guys at?

Rips might not be the cheapest but they are in great shape and will haul ass. I know I did them. You might find cheaper but not better or faster.

Its a dune thing. You would understand if you rode and raced in them. That picture represents everything I do. Hill shoot and dune. I have no stickers and only a few XXLs on the original shirts. I will get both made here shortly.

Grim, I really like this one! We could play with it forever and never make everyone happy. I want to use this one. Send it to me in an email @ [email protected]

Something is out of adjustment, bent or end of life.
