Glad i've been collecting junk bikes for parts.....

Also had a sudden fuel starving problem.... Had fuel flow to carb, had flow thru the float valve but it would just starve, and or airlock and die....Let it sit for a minute and it would go....

Tore the carb apart , cleaned everything and it still did it....Tore it apart again and recleaned everything and it seems ok now...... hmmmmmmmm.....

Busy day.....
Check the gas cap. The tank needs air flow. Bad tank vent (in gas cap,) will do just what you described.

I've been wanting to go Springer front end but don't want to lose my disk brake, how it your caliper mounted? Did you weld the tabs on? I have a welder but would rather not weld onto brand new forks with my little chinga welder...

Hey bro, After looking very closely at the setup he has, you can see that it's a mount plate, attached through the front axle and kept from spinning by a bent tab. I don't know if he bought it or made it himself, but I've seen something similar on ebay.

Hey there.. for my front disc brake I made the disc adapter using some 1/8" flat plate I had laying around. I used the same concept that others have used that lksdG2 mentioned. Its completely bolt on, so no welding. One of the best upgrades so far, since its no fun riding if ya cant stop in time

Boygofast sells this one cheap enough. It also attaches to the front axle, and looks like a mount hole for a upper clamp or whatever.

I am using V brakes on a bike that only had coaster brakes and now has pedal crank swapped for dirt bike foot pegs.

Slower speed like 5 mph on dirt I can skid the rear tire. Together front and rear at like 10 mph can stop pretty good, but this is with my ratio at 40:1 parade speed set up. I will for dirt bike have 20:1 change over.

I see with 9 bucks shipping and some tax under 35 bucks.

I am going to see if there are any in local stores that can compete with this.

Apples and Oranges quality maybe have to make some adjust for comparison, but I when looking at drum brakes had seen usually from 50 on up to maybe 150 bucks and was quite against going to a more powerful stopping brake system.

I also like the idea that wet conditions are not as bad where the exposed components are compared with rim brake systems. Drum though with spoke lacing cost I know you can add to the cost where I can tackle the disk assembly I think!
