My 2000 X1 carbon tank cover has about a quarter size hole on each side that appears to be non-functional vents. Yet, I see on ebay that there are tank covers that claim to be X1 that have no wholes. What am I not knowing?

as far as I know only the 99 model year had holes. They disappeared in MY 2000,the covers however are interchangeable. I personally think they looked better... Greetings | ||

Would they not allow water and whatever else in there? Not that I spend much time riding in the rain. | ||

Bobo: According to 1313 theyre' acually functional scoops. The tank is plastic and any water or dirt that is "scooped" is of no concequence. | ||
| Bobo |
Is 1313 a user id? Would really love to know what is their function. | ||
| Jos51700 |
They're functional in that they scoop water and dirt into the area between the fuel tank and the fuel tank cover. Every '99 X1 I've worked on has had it's own little sandbox under there. | ||

Great info. 1313 said they were intended to direct air to the rear cylinder but they quit making them assuming they did not excel at that function. I see someone saying that in 99 they also had tanks without covers. Such as this one: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?Vi ewItem&sspagename=ADME%3AB%3ASS%3AUS%3A1123&viewit em=&item=270207396180 Is that correct, they had both tanks and tanks with covers? Sorry, for the noob questions. | ||

Those scoops are a styling exercise only. There is no passage between the tank cover and the fuel tank leading anywhere, let alone to the rear cylinder (Which is why each of these X1's has it's own little collection of road souvenirs). The area behind the instrument cluster is a low pressure area, anyway. The scoop on the left side is designed to enhance rear cylinder cooling (and I wonder if the people that toss them realize that). That tank on ebay is a '98 S1 White Lightning tank. All X1 tanks used covers, as the cover had the mounting points for the aforementioned scoop and airbox lid on the RH side. Early covers were painted, or Carbon Fiber, later covers were color-molded plastic, typically with vinyl stickers. Also, the white tank has a fuel valve, not found on fuel injected X1's.

From what I can tell the 98 tank will not fit on a X1? Assume a carb conversion that could use the fuel valve. | ||
| Kyrocket |
X1's were new in '99 and fuel injected. I don't think that tank would fit without some major modification. And Jos is right, all X1's had covers over a plastic fuel tank. | ||
| Jos51700 |
The rear fuel tank mounting is different. I believe, but am not 100% positive, that the S1 tanks will fit S3's. But I know of no other tank that interchanges with X1's. Anything will fit with enough modification, but these are not bolt-in swaps, so to speak. What are you wanting to accomplish? Many creative minds here with lots of ideas....... | ||
| Bobo |
Tossing around the idea of converting to a carb. An S1 tank would take care of things like the tank accents (if I remove the sides knowing that the left has a distinct purpose) and fuel valve. | ||
| Jos51700 |
I personally prefer the FI, but I also know how to work on it and so can understand your plight. I would simply install a fuel pressure regulator in line, and reduce fuel pressure to 1-2 PSI or so, then route line accordingly. I don't remember if there is a strainer in the tank, but there should be, and if so, you can ditch the external fuel filter. The pump might not like being choked down that far, but it's internal return so I doubt it will have any problems. This would maintain the low fuel light operation, and all that good stuff. I also like my method because it's easily "un-do-able". Alot of people have converted X1's to carbs, and so there's many more ways of doing it than mine. The retention of either a fuel light, or a "reserve" fuel valve are the two main concerns. | ||
| Jos51700 |
You may be able to simply add the single-bolt retention at the rear of the tank that the S1 and others use, and go about it that way, but I don't know if the fuel valve will clear the frame rail. Having a tank handy would make the options available become obvious. | ||

+1 on FI. Eight years and (knock on wood) no problems. | ||

The idea of the carb was convenience and reducing clutter, and I have a tuned carb just sitting here, and thus no time and effort with FI. Loved FI on my trans am and spent much time in the software and even helping develop software for it. However, bigger gains were always had with a conversion to carb. Yet, that is a drag racing application only and I will just be riding on the street and dream about the track. I am sure I am going to have plenty of time to dig into ECMSpy. And I surely know the benefits of FI. Plus, there is always that thing about climbing the mountain just because it was there - switching to a carb setup. | ||
| Jos51700 |
Switching to a carb is, to me, the easy way out. Carbs outperforming FI? Do top fuel cars use carbs? To me, FI is the clear winner, just not the DDFI I or II. Idle air control, constant fuel ratio regardless of altitude or weather (Speaking of climbing mountains, FI will make it to the top every time....), plus the ability to run mega-huge throttle bodies without nasty, excessive, inefficient accelerator pumps. It's a no brainer in MY book, but I can dig running the carb. If you like to climb mountains, why don't you adapt a REAL FI, like the DDFI III or HD Delphi to your X1? Then you can really build a hot setup. It's only clutter if you don't route the wires well. I love FI more than carbs, but this Alpha-N on the X1's is friggin' antique. The only reason they ran it was because they wanted to create an FI system that had the same cost as a Carb (which they succeeded at). | ||

Well at least with the LS1 they were making more power with the carb setup. But, in any case, yeah, I kinda agree the carb is the easy way out  So, what do I have on this 2000 X1? A DDFI I? What model has he DDRI II? |
