I agree you should not proceed without getting another good battery to test with. Be sure to check all the associated ground points. A little patience I am sure you are almost there. It will certaianly be a WTF moment when you identify the problem.

@BergDonk: As far as I know, the TM38 does not have a built-in fuel filter. I have the Aqualine tank with two petcocks and there are screens on the inside of them. I then have an inline fuel filter (paper core) where the two fuel lines meet and before it goes into the carb inlet. Good idea on viewing the float level. Will try that when I get back to civilization.

Here's an exploded view of my carb: http://www.sudco.com/Diagrams123/exptm.gif
Anything you see in there that I can fiddle with?

@Nullarbor63: thank you, my friend. You are right that I am getting hung up on it being an electrical issue but I'm open to it being related to something else. It's just that I can't diagnose that here but once I'm back to a city, I'll do a full tear down and investigate. Thanks for bringing up the cylinder head crack issue. Didn't know about that.

@greer: you have a valid point and yes, it could be the Shorai lithium-iron battery. I'll test with a regular one once I'm back to Nairobi.

@nsrrider: yeah, I dont think it's the resistor. thanks.

@Randomroad: I can't wait for that WTF moment!

Well no Flow, we should expect one to call ahead after the long ride to Texas to make sure one had a tire waiting. Like I did in Battle Mountain Nevada while riding the TAT. It was pretty easy, I called a bike shop out there before we left NJ and had him order us tires. He did, they were there.
We continued on..........

Pretty easy

Loose the edge there friend.

I couldn't find much info on this thru search...

How much difference was there and in terms of weight/power ratio, any drawbacks?
I did it. The mother moves. Tons of smooth power. I recommend it.

790 kit

You might check out DRRIDERS.com. I think there were some reports of it posted there. I plan on doing the kit this spring.

Have you done any other mods to the bike, or just given it truckloads of awesome power?

Someone might have said this already: Any bike that I have had that would start when cold...run for a bit...then shut off and not re start until time has passed has for me always been a gas tank vent issue. Next time it does it make sure the tank is venting correctly. Take the cap off and try starting again. Also, make sure your fuel lines are not near the cylinder head. I never heard of a bike having fuel vapor lock from heat boiling the gas, but it sounds like you have checked everything else...

I have never been inside of a TM38 so I don't know how the float needle is hung on the float. On some carbs if the float is not hung EXACTLY how the manufacurer reccomends it can hang/stick in its little tube. Most often this results in a lean condition but still runs or will start and quit as soon as the float bowl runs out of gas. Edit: I looked at the carb link you provided...doesn't look like it can go but one way. hmmmm.....

Do we need to send an Old Priest and a Young Priest and have an exorcism? I'm sure you can find someone to swing a dead chicken over that thing! Good luck brother.

I just shopped tires (5 mins ago after seeing the name) at SWMT and their prices seemed pretty good. Anywhere better? I love saving munney.
many buy tires from MSS http://www.motorcycle-superstore.com...res-Tires.aspx
buying a pair will almost always be enough for free shipping - $90+

Nothing jumps out at me and it doesn't appear that you have a drain on the float bowel. I have in the past drilled the float bung and threaded and epoxied a hose fitting into it so I could track down a float level issue. But I also had a spare bung to do it to.

As you have a decent external inline filter, I'd get rid of the screens inside the tank. When they are hidden away, they tend to be ignored.

And as someone else suggested, tank venting?

gsxr muffler ?

Took a chance on a GSXR muffler from ebay.

It is the coveted 40FO.

Description said it sounded like there were loose parts inside.

I received it today and shook it, something sounded loose. Held the 4 bolts on the end, shook it, sounded like maybe a very little loose sand inside but nothing mechanical.

The end cap bolts have very small factory welds on them so I know it hasn't been screwed with.

Am I good to go? Should I try opening it up or leave it alone?

You are good to go.
The sound is probably just some of the small pieces from the donor bikes pistons when they disintegrated.
There really is nothing inside there to come loose.
The mid baffle plate and two short tubes welded to it.
All wrapped by a perforated tube with a thin permanent sound deadener between it and the shell.

How much did you pay for the muffler? I'm looking at swapping too.

First off I have to say I highly respect you for taking on an adventure most folks would never attempt, including me. Kudo's brother
Second I would get a compression and leakdown test if at all possible....if your bike has 74k original miles on the engine this prob could very well be engine related.

Also be sure your vacuum petcock is working right if you're still running it. I always ran my vacuum petcock machines on prime and skipped the vacuum set-up alltogether...they always seemed to give me probs with leaking diaphrams and fuel starvation.....which can often seem like electrical probs.

Good luck and hope you can forge ahead with this awesome adventure

Have you actually read Jay's Ride Report? Go read it. Then you'll realize how far ahead of you Jay is. He's forgotten more about DR's than most of us know ... or will ever know. (this is his 3rd DR650)

Jay is also an engineer and a very good tinkerer in his own right. Once you've read the WHOLE Ride Report you'll know where his bike is at, what's been done ... and just how competent he really is.

Trust me, Jay is on the case ... whether it's fuel or electronics?
Are you a betting man?
