Here is my 03 Hybrid build.

Post by ebeck »

I'll create a complete walkthrough when I am done.

Big ass box of goodies from Krazinski!
Image

Couple of sihny new goodies hanging on the wall as Kawasaki. $175 foot foot pegs is a bit much if you ask me....
Image

Here is how the motor lies up out fo the box
Image
Image

Tracing out new front mounts
Image

te rear mouts cut off. Actually you can reuse these, the mount point moves higher to the outside on the frame tube is all. Just shorten them from here.

Image

Here is the swingarm to sprocket line up. Not horrible, although motor will be a bit lower in th final assembly
Image

Look at the shiny new swingarm. Not the right frame...
Image

I bought fot pegs, frame guards and bark busters and it cost $350. It adds up fast. Getting new parts like brake pads, chain, new tires, rims, spokes, clamps, bars, levers, pipe, pipe guard, plastic, graphics, coupled with labor cost and motor and suspensio rebuild it can cost alot quick. My last FULL motor rbuild cost $900 alone.

Of course you can just put the parts on as is and ride and save a ton. My objective is to have a bike factory new and fresh when done. There are no short cuts when startig off with used parts. Starting off with a new 125 would probably be better and cheaper actually.

Cutting the front mounts

The boys KX65
Image


Here are the new motor mounts. A bit rough and unfinished to be sure, but the hard work is done. I removed 1/4 off the rear mounts and will reuse them.

All done. Bike is dirty and camera sucks but you get the idea.

I think I need to narrow the rear lower motor mount 3/16 an inch or so to get the mounts on the frame in the right place.

Rear lower motor mounts can be narrowed with a dremmel and a cutting wheel. Many manuals say when bolting a motor in "shim as necessary". I use copper washers to get a tight fit. The mounts prevent up and down movment not side to side, so it does not have to be shoe horn tight. It does have to be pretty close though. 1 mm or 2 mm gap is OK and can be shimmed (washers or what not) as long as the surface is dead flat.

You can get precise enough with a Dremmel a small square and patience. I have done it twice already. Proably the easiest part actually.

Here is the rear stay. Not completly groud and cleaned up yet.

Image

Problem with the bottom rear mounts is that the mount sleeve on the case is pretty wide. Either you have to make tiny mounts and get the mounts welded on top of the frame (the least optinal of all places to weld) and even then there may not be enough room for the bolt head or grig the case sleeve down a tad with adremmel and a cutting whee. Pretty easy actually. You can see the problem clearly in the below photos. Oh, you have the same problem othe 2000-2002. The 99 frame the KDX motor actualy lines up with the bottom rear mounts.
Image

Another look

Image

See where ther mount is, pipe mount has to be moved to the arrow, or there abouts depending on what and how you do things.
Image

Here is the top mout, I am going to create a bracket as shown below.
Image


That is all for now.

Rear bottom mounts. Plenty of room with the new slightly taller motor mounts. That's it, time to get it welded!

Based on your lower motor mount pics you may have your engine tilted a little to far forward. I would put your right rad on with the engine in place and look at the clearance between the rad outlet (with the hose on) and the KIPS before you wield every thing up. [/img]

The process is the same for any mount, exhaust o motor.
Use one of thse to measure curves

Xfer to paper

Cut and line up, grind as needed
Image

Here is the bottom one lined up too

Here it is all ready for welding

Do you like the throttle cam? That replaces the entire stock throttle assy right? Looks like the cam in not covered.

I am still testing the throttle cam, I changed between the 200 to the 400 and will report back on it late wed.

I just made a lot of changes all at once now I need to back track a little. the JD kit made a big change and I changed from the works pipe to fmf gnarly.

At the moment the 200 wiich is the middle cam has the bike hitting hard off the bottom I am trying to mellow the first 1/8 to 1/4 throttle out just a tad to keep her from shooting up a tree in the technical sections.
