2000 KX500 Project

[Pmcg]

The guys at Packard are awesome. Had it to me in 1 day. Charged me less then we agreed on. And spent 1/2 hour on the phone talking about install and how the 500 is more bike then I need.  I'm in the process of boiling my intake boot now to get it to mate with the carb better.

FYI. They come from Packard set very rich....

Which NEEDLE did they give you?

I'm pretty sure it's a 52 xl. I have the power jet screwed in 3 turns. Hopefully I get a chance to try it out tomorrow.

Do you want my base numbers for a stock motor. Or you want to run what you got first?

That would be great. Thanks. My motors slightly bored with an 88mm piston, Todd did some port work and adjusted the squish. 10mm reed spacer vf2 fatty pipe and turbine core silencer. I have Alex's electronics on it at 87 btdc.

Yes. Packard have me the 5.2xl also... But my big bore didn't like it.. (I'm 90mm).  

Most k5's at your state of tune end up on a 4-2xl needle set at 2.025"  and the power jet set at 1.25-1.75 turns OUT FROM BOTTOM. At sea level

With the big bore (not sure if 88 will make it show up). 90 sure does... You will have a lean spot right off idle (think throttle opening it takes to idle across flat ground in second).  That is a bitch to tune out....  

Like anything jetting...  Use your head..  Don't blow your s**t up because of what some guy on the net said...

So the 5-2 was way to rich the way it came. I ended up leaning it out 1.25 turns. I spoke with Packard today. They seemed to think that the 5-2 was the way to go. They said that my foam filter was likely the issue and that I should try a k&n cone filter. I'm going to give it a try. The bike revs really quick but surges pretty bad after I cut the throttle.

What's the measurement on the needle

[Pmcg]

I'm not sure.  How do they measure the needle?  Is it turns from bottomed out like an airscrew?

[Pmcg]

New filter cam in and its huge

[Pmcg]

Packard said its a big difference.  Said to get rid of the air box all together.  Problem is I need a place to keep all the wires from the headlight, horn, and brake light.  So I got a bit creative with the dremel and fiberglass

[sandblaster]

I need one of those filters for my dedicated SM build...

Have a stock 2002 motor with the 40mm Lectron.  Had the same issue Motorrad describes here

"Yes. Packard have me the 5.2xl also... But my big bore didn't like it.. (I'm 90mm).

So tried a 5.3xl...lean spot gone.  But too rich everywhere else.  Have the power jet at like 7/8ths out...still get slight bogging when putting around then hitting full throttle.  Wonder how the 4.2xl would be on stock motor with 40mm?

[Pmcg]

I'm still having some issues. Really hard to start and it won't iddle. I'm circling back to the timing now. The bike has great top but a stumbly low to mid.

[Pmcg]

Hey guys.  I still can't get this bike to start so I need some help either fixing the issue or pushing it into the lake. 

Motor is completely rebuilt and holds a vacuum

Ignition is power dynamo set at .86 BTDC (had some issues with timing mark but it should be sorted) good spark

Carb is a lectron 44MM

Piston is windowed and Larry's compression release is in

Could the compression release be causing the starting issues?  The bike will roll start but wont kick start.  I'm confident that I'm kicking hard enough.  With out using the comp release the compression is insane and I worry about breaking the lever.

Could the window in the piston be causing the bike to pull in too much fuel?

I know that there's not much else to it.   I have spark, gas, compression.  Any ideas?  I'm starting to hate this bike. 

Thanks
