Air/exhaust leak?

UPDATE: all the gaskets are replaced. Fresh gas and 32:1 mixture. Plus a brand new carb. It has stopped spraying gas everywhere but still not running quite right
It idles great with the choke on but rpm’s increase when choke is off and dies when I turn the throttle. Any ideas?
Sounds like an air leak.
 
Running lean, drop the clip on the needle jet one notch.
The clip was in the middle and I moved it 1 notch to the top. I totally had that backwards! I’ll give that a try when I have some time
Sounds like an air leak.
That’s what I thought but when I spray with carb cleaner it doesn’t appear to be a leak
 
So played I around a bit more to get this motor to run and was gonna switch the carb for one that I know works but I bought the Phantom85 instead. It was open box unused for 190 on eBay. It’s missing the gaskets but otherwise appears to be in great condition.

I also bought the BBR 3 spike mag wheel set that Damien has recommended time and time again!
 
Don't forget, you may need these instructions I have made to get things on there and working right...I know what its like to be just futzing around trying to get things to fix so here is some of the benefits of my experience being passed on once again...lol.


I don't recommend this method on an aluminum frame because it would probably crack and break, but this is what i did on my Steel Frame Hyper Beach Cruiser to accomodate the rear sprocket and disk to fit within the dropouts and frame.

On my bike, (steel frame ONLY), i had to "stretch" the rear forks apart by hand, about 1/2 an inch to put the rear wheel with sprocket/rotor attached, and then use a spare 15MM axle nut on the sprocket/rotor inside of the drop down, threaded to the axle with blue locktite, to maintain that amount of "stretch" to accommodate the amount of of clearance space the rotor needs so as not to be pressed against the frame.

It helps to have a buddy with a strong pair of hands to help in this proceedure like I did...lol.


You will also need a freewheel sprocket for the pedal chain side of things as well and will probably need to add chain links to the pedal side as well since the freewheel is larger than the stock coaster brake pedal sprocket.

Ps...I also eliminated having to use a chain tensioner by cutting the drive side chain down to custom fit like a motorcycle chain when i also did the pedal side chain sizing so they are now both custom fit for the bike.


A pair of these adaptors (2), one for the front, one for the rear, will also be necessary, or something like them since you may or may not be able to make your own frame to disk caliper adaptors as i have done.


And a dual brake lever for the disk brakes since you already have the clutch lever taking up real estate on the left side of the handle bars...lol...also on sale for 10 bucks for the next 16 hours....You will need brake cables from your local bicycle shop as well to connect the brakes.

Thanks again Damien but I’m one step ahead of you. I already have screen shots of your instructions and already purchased those parts!! Haha! I know you have good info and build a solid bike so I buy what you buy!

One question tho. The disk brake adaptor says it does not work with the dropouts that take the wheel from the bottom. I noticed you got it to work for your bike. My question is do I need to cut the fender mount holes to make this work?

I have the style on the left

He custom built his own.

Gordy is correct...I made my own for both front and rear...lol.

I used 7075 T-6 aluminum for the rear and believe it or not, I used an Adel clamp from military aircraft to hold onto the front caliper adapter...They have been working flawlessly for three years now.

Oh ok. I thought you used the one from bikeberry. I’m gonna give it a go and see how it works. I may have to make it work
