Has anyone done it? Is it that hard? If you have done it, how did you do it and how did it turn out. Were there any problems i should know about? It doesn't seem like it would be that dificult, but i have never done it.
Also i plan on a BW hardtail with 3.5 streach. Does anyone know how much rake i can get away with before i need longer fork tubes? Thanks MIKE

Mike first thing you need to do is check your state laws. In vermont for instance you need to take a straght edge and going parrelel to your forks and centered to the center of your axle, run the straight edge to the floor. now lay a frameing square flat on the floor and up to the center of your axle. Now you can measure the distance from axle center to the fork distance. vermont DOT says no more then 14"

I'm not trying to find the max rake. I'm sure i will not do anymore than 38 degrees rake. Probably less. Iguess my question is will i need longer fork tubes if i did a 38 degree rake?

I wouldn't try it myself. I'm working with someone who knows what they're doing. Not a good place to have a frame failure when you're running down the road. Also I would assume you need fork tubes a bit longer to keep enough ground clearance and to keep the bike level.

Well I thought i may need longer fork tubes at first but then i got to thinking, When i weld on the hardtail that may lower the frame in the back. If it does than the front would be a little higher, and if that was the case a person could rake the front with the stock length forks until the frame was level again. At this point i don't know this for sure since i have never done it, but i will find out when i get the hardtail welded on.

76 is your bike presently together or apart?? If the forks are off adjust the intire rear of the bike includeing rear wheel to the ride height you are looking for. Now place a magnetic angle finder on the neck of the frame and measure the angle. Now tape a piece of string( LONG ENOUGH TO REACH FRONT WHEEL) centered to the top of the neck. Now on the wheel end pull the string forward with the angle finder resting on the string to the deired rake. measure the lenghth of the string from top to axle. This will be your fork length needed to achieve your look. By the way I built a bike once with a hardtail and didnt change the rake at all and ran the 35mm forks for a bobber look, I also have a chopper hear with same frame configuration with 8 over forks.

Hi...I'm a newbie here, but figured I would post a pic of the bike I built this winter.

I raked the front end out I think about to 38 degrees. I didn't do anything to special when I did it though. I had built a jig to hold the front 3rd, what was left of it. And then a jig to hold the rear axle in place in the rear triangles I made...while the whole jig was designed to hold the frame 4" up. After I had fabricated the frame I cut the lower gusset off the front, the 2 triangle gussets off the side and cut the top pipe next to the head tube in half and cut the lower 2 pipes completely off.

I then put the fork tubes and front tire on and pulled the fork tubes forward until the front tire was just about to leave the ground. Tacked it back up and welded everything solid. Then made new triangle gussets on the side that were a tad larger and thicker than the orginal, 1/8" thick.

Anyway, not sure if it's right or wrong...just what I did. Pic taken is without the seat covered, I had made the seat pan using chevy 350 valve springs for the rear suspension in the seat. Seat is now covered in black leather with a 1/2" of foam.

I chopped an xs850 a few years back. What I did was get lower shocks(cut the springs) and 8 inch over fork tubes, I put blocks of wood under the frame for the desired hight and cut the front down tubes with a sawzall.

The bike sagged down to the desired rake and I measured the gap in the tubes, then cut pieces of 5150 chromoly I had bought from some experimental aircraft guys and welded them in place. Worked perfectly and tracked straight.

If I remember correctly it was a 2 and 1/2 inch stretch on those tubes. The total cost for the scrap chromoly and the welding was less than 50 bucks.

what i did and i was only 17 it turned out awsome i cut almost althe way threw the frame just behinde the neck cutting up NOT DOWN then put a long bar very long its easer to keep it straight threw the neck and secure it tight so it doesnt move im asuming your changing the bearing race to a tapered bearing i tack welded the bar to my old bearing race how you do it is up to you Smile and start pulling the bar from the top and some one puling from the bottom keeping an eye on the bar for straightness use the back bone of the frame as a line when you have the rack you want cut a wedge that will fit in the space and weld it up an inch at a time from one side to another so it doesnt pull one way or the other . worked for me

cheers

Easiest way is to convert to '77 & up 35mm front end & get the 4" overs from Mikesxs.

Otherwise get forked by frank, whatever size you want!

a lot involved there, lenght of steering stem ect. but here's some with the same bearings any way ..... caveat emptor, use at your own risk, most of these aren't going to look a lot different than what you already have if you're thinking of a girder or springer fork you're not going to find a bolt on solution

Black/white bike is 40deg with stock length forks, the other is 42deg with stock length forks and the last one is 42deg with 2" under. Raking is NOT my favorite thing to do, for me was a pain in the ass, for others maybe no big deal? Depends on skill level and if you're a perfectionist or not.
