Too much rake

I hope that it works well. Remember the added leverage that the new off set will create. Also look around for some progressive springs , you will be truly thankful for the time and effort. Also I,m looking for a shim stack washer shock to use on my springer ,if I find one I'll let you know. Later this summer I plan on building my own fork, a redo on the harmon spurder with a hydraulic dampener that I designed over last summer.

Thanks for the info Doc. My triple trees are not offset, they are parallel. I made a pattern for a new set of rockers, using my old ones for the placement of the bolt holes for the legs and moved the axle holes forward 4 inches and up about an inch. I raised the axle holes like Sugar Bear does and I believe they are about the same as his #3 rockers. I pretty much free-handed the curves, with the help of some assorted plastic lids and kept comparing them to his rockers, so they look similar. I...

If you don't mind 2 cents worth. I've been studying rake and trail for about 1 1/2 yrs. there are 2 schools on it and some people use what is called true rake and trail. I'll get to that later. I spoke to SugarBear over the summer and he taught me a lot , he loves the 750 and was one of the 1st. to chop them, I think. But his zero rake is because of the excessive length and weight of he forks and should not be used for regular rakes , ie 16 over and under. He also drops the bottom...

Cool, I'll see if I can get some coming. Makes sense to me. I moved the axle out 4 inches and down about and inch.

they may depending on how far out you move your axle. I run Die springs from mcmaster car, they got different sizes and strengths

Hellbilly,

Are they going to bottom out? Where do you get the inner springs?

Re: Too much rake

feeds@yuku.com (hellbilly1932) — Wed, 30 Apr 2008 17:39:56 GMT

you're gonna need to run inner springs in the lower springer springs to deal with the increase in leverage.

It's all math, that's all, and he has had years of R&D!! Study the pictures, it isn't tough to figure out what he has done, he just sets them up on a jig that took a few trial and errors to figure out. but if you take one side of your rockers off and cut the rear two holes of the tracing and then move it around, use 1/4 in luan wood so you can adjust your pattern, make a few different rockers, you can get the same results, just take you more work than it would him.

Java,

It looks to me that it drops the front end lower, which slightly changes the rake angle, also reducing his trail. Most of his front ends have zero trail. I dont know how the hell that works, but he drives around one handed all the time. He must know something we dont.

40-45 deg with a springer is just fine, if you take a piece of anything to make a pattern of where your rockers are now, and move that wheel forward straight enough to reduce the trail to what you are comfortable with, ( I'd start at 4 inches) then design the outer design around the holes in your pattern board. Then fire up the laser cutter and away you go! I was eyeballin a set of sugarbear's and you may notis that the ends of his springer, where they mount to the rocker is lower...

Grim,

Im about 40-45 degrees of rake also. Looks like Im going to make my own rockers. I cant live with it the way it is so we'll see how it turns out. My wife works at a machine shop, how can you beat that? Thanks for the reply.

Roy,

Im in the same situation, I have over 8 inches of trail, but I got stock tubes so there isn't much adjustment. Especially since I'm already at 46 degrees of rake, anymore and the lowers wont ever move haha. Sucks raked trees are out of the question. Thus continues the quest for a springer. Good luck bud.

P.S. For now, I've just gotten used to the heavy flop, so much to it's a little weird to ride my Dad's stocker.

Thanks Java, My mistake, I should have said "Too much Trail". I measure about 8 inches from the steering axis to the radius of the wheel (straight down from the axle). There are many opinions on what the correct trail should be, but the consensus seems to be 2 to 4 inches of trail should work good. Of course this all depends on the frame, weight, springer and everything else. A safe ride is my ultimate goal. I dont want to hit a pothole on the freeway and ride a tank slapper into...

Hey Roy, I have a thought on this, keeping in mind that I have not actually done it, BUT,

If you block your bike up so the frame is level, use a length of straight something,( pipe, tubing, lumber, straight edge) and run it down the NECK , parallel with the centerline, that should give you a spot on the floor, then drop a line from your axle straight down to the floor, that will give you another spot on the floor, difference between the 2 is your trail.

Keeping the same...

I pulled my bike out of a barn and it had not been touched since the mid 70's. To make a long story short, my present front end was only slapped into the frame to move it. It had never been ridden like this. The steering neck was the wrong diameter so I fixed that but my trail is about 8 inches. My steering is very heavy and flops to the side. Anyone have experience making their own rockers like Sugar Bear makes? He doesnt sell just the rockers, he only sells the entire springer....
