One last question before I put this back together tonight, Does anyone know what the cam chain pin to pin service limit is? I looked for it in the manual, but it doesn't seem to list it.

I don't have the manual for your bike but on my 98 the 20 link numbers are:

Standard is 127.00mm-127.36mm
Service limit is 128.9mm

It won't necessarily be the same, but this gives you some idea of where the limits are.

Well, I got the motor back together and back in the frame. I went on a short ride on the KTM (rare opportunity for Ohio in March) to pray to the bike Gods, and then came home to push the start button. She fired right up and sounded great!!!! I'm SOOOOOO happy! Now, I don't know if it has any power,,, but I'm just happy it runs. Thanks to those of you that offered words of encouragement. Now I can move on with the rest of the project. Compression test tomorrow.

Well, the compression test is done. Not as high as I wanted, but still not bad. 210-215-210-210. I'm guessing that's not too bad for a bike with 14,500 miles on it. Maybe I will ride it for a while and then do a little cam timing. I think I still have my degree wheel...

That鈥檚 actually pretty good. 150 is the low end. Did you do this with a warm engine and also open throttle while you crank it? 230 is the high end of comp so if the engine wasn鈥檛 warmed and throttle open you will get a little lower number than it really is.

I see that a popular chain and sprocket kit for this bike is a 14/45 520. That's -1 in front and +2 in the back. That seems like a huge jump in gearing. Does anyone have experience with this set-up?

That is a pretty major change in gearing at 12%. If you were turning 6000rpm on the highway before, after you would be at ~6700rpm. I would find that annoying beyond words but lots of people seem to be OK with that sort of thing. I've never seen much point in gearing changes for street use unless you are stunting. A 12% shift like this basically just means you are running one gear lower all the time. That can easily be accomplished just by running one gear lower and then you keep the lower revs at highway speeds for less buzzy travelling.

6k and 6700 really isn鈥檛 noticeable riding the bike for me

But the 1 down up 2 is popular because it gives you the bottom end pep and doesn鈥檛 reduce your top end. You鈥檙e just rev limiting top end and getting there a decent amount quicker. Im running a 15/48 on my 20 currently. My top end it lowered to 135 (gps) but that鈥檚 about as fast as I care to go on it being it鈥檚 mostly a stunt bike. I ran a 15/55 for a good long time when I first got back into stunting 80mph was almost 12k. It was fun just cruising and city but it was annoying as hell on the interstate and straight stretches. Once I decide on a dedicated street bike and this one is my new full time stunt I will go back to the 55. Just waiting to see if we get a new gen 636 soon. If not I may get a litter bike 馃槻

I think I may just go 2 or 3 teeth up on the back. Well, since the motor is back in and running fine (after all my worrying), I can move on to other stuff. I think my motor problem was too much fuel coming out of my spark plug gap...... Anyways,,, painted the back wheel today. Found some epoxy paint that I hope holds up a little better than normal paint. I was going to have them powder coated, but the price seemed a little steep, so I thought I would try this first. This paint is a pain to work with, but looks ok when done.

:ROFLMAO:

It's always that damned spark plug gap.

That looks good. What was the brand/type of paint you used?

Lol. I see what you did there 馃ぃ馃ぃ馃ぃ馃ぃ. You can always install a resistor in your coil wires to lower the amount of fuel it spits out. Just some math to figure out. Seems doable tho.
