carbs & simplicity

As John Biccum pointed out. (In "Rants")
There are many road (AND OFF ROAD) "issues" that can NOT be resolved with Computerized fuel injected bikes, THAT CAN BE SOLVED With simple carbed bikes. (KLR etc.)
I other fields I have seen the same ISSUES!
This last winter my 97 F250HD, the  460 (7.5 L) engine started acting funny.
symptom's varied greatly and at different RPM's & speeds.
Thinking the Computer was bad, I broke down and paid $395. to have it looked at & repaired. 
$98. (ya not a simple even $100.) was to hook it up to their computer to see what was wrong.     SIMPLY A bad PLUG WIRE.  
The computer was trying to compensate for an intermittent  miss, causing the symptoms TO CHANGE.
In the Food Industry, most think the fancy ($$$$$) more "efficient"? new (last 20+yrs) computerized equipment is the only way to go. 
Then when the smallest thing goes wrong, THEY ARE DOWN.
One January, Panera Bread was down 3 nights in a row. 
Parts, Computer's etc ($$$$$) were flown in next day air. $$$  
They start cooking about 11pm, The ovens were working fine each DAY, we checked them over, changing things, and at night, they would go in and out.
On the 3rd night, I was brought in on the issue, (I live & think outside the "BOX") We we on the roof of the large Mall, ICE AND WIND, Blowing us backwords as we CRAWLED hands and knees. 
After About 1/2 I realized, everytime a wind gust came over the tall peak the guy below (WARM INSIDE) see a change.
The Wind gust would push on the vent and change the exhaust readings, so the computer would comensate or just simply shut down. (PROTECTION)

If you want to go lower tank then just convert it to FI. I have ridden both. FI kicks @55 and is way easier to live with. It also buys you the space to lower the tank then put the air intake up by the top of where the tank was. If you are going to go as far as moving the tank you might as welll update the bike :-OOn 7/7/2014 6:37 PM, 'Norm Keller' normkel32@... [DSN_KLR650] wrote:
[quote]   I keep thinking of the approach taken in many bike designs and wondering about applying to the KLR. Part of the issue is long suspension travel & such but the fact that it is easier to lift a dropped 680 pound Honda ST1100   than a 420 pound KLR is interesting.... One advantage to many bikes is that the fuel tank is placed lower in the bike. I keep thinking of the ST approach in which the carbs and air box sit in the fake tank (turtle shell) with the fuel sitting down behind the engine. Anyone happen to have the air box and carb off a KLR and can take some dimensions & photos. I keep forgetting to do this when things are apart. It would require a carb swap but how about a down draft carb with air box above and the fuel tank down in the frame? The Honda fuel pump only requires 1.1 amps so that would be doable.
