I'd buy it.
Get proof of the updates that are done to it.

was the gas tank filler neck issue on the '03's? i cant remember...that would be an example of one you'd want to get/have fixed

I would buy that sled.. Make sure it has the updated rails, gas tank, and steering.. The 03's were the fastest out of all of the F7's not sure about the lightest.. Go for it you cant go wrong!! Look at the rails, make sure there arent any cracks..Compression should be about 135/140 ish in both cylinders.. Give it a good looking over and then buy it if its nice!

Ok, Sled bought! Steering Update done along with oil sender update, said tank update was a non-issue. The only real concern I have about this sled is the seller said he never cleaned the APV's. I can only hope for the best. I've cleaned them out on my 01' ZR600 and replaced them, I cannot imagine it being much worse. Does ne1 know of a good tutorial to cleaning them out?
I'm pretty psyc'd about the Sno Pro track/suspension!

There you go.. That shows you what to do... When i clean mine, i take the valve out, there is a little allen screw that you unscrew and can pull the valve off and clean it on a bench.. I also use WD-40 and a razor blade and scrape them off, being careful not to scratch the valve..

How about the suspension rails, have those been replaced/updated? I think there was an update for the 03's.. Look for cracks on them..

Also, look around the filler neck on the gas tank make sure its not cracked, because it IS an issue, yours might just not be cracked, like mine never was..

Post some pictures of it!!

Well I cleaned the Valves but problems... The servo isnt turning, I'm hitting 50+ on the jackstand it should start moving shouldnt it?

I had the dealer run the VIN to check for the recalls, the steering hasnt been fixed, the guy lied to me =( but no big deal they said its a 10 min fix.

-Thanks Guys!

Easy fix, at the dealer, yes about 10 minutes..

Servo should cycle 2 times i believe around 7K rpms? Pin the throttle and they should open.. When you cleaned the valves did you check to make sure the cables were in spec? Should be 34.5mm

beefey · 07-14-2007, 01:37 AM

I dont understand why that matters about the cables... if they are 5mm or 35mm. The servo makes a complete rotation and will pickup all the slack anyways right?

PS are these bad news? Looks like the engine is running way rich right? How do you fix that on an EFI?

**smallengineguy** · 07-14-2007, 02:44 PM

I saw your other post. Looks like oil rich, not fuel. Check the oil injector also.

**smallengineguy** · 07-14-2007, 02:44 PM

Also, are you running it in 70 or 80 degree weather? It'll definitely be too rich in those temps, EFI or not!

beefey · 07-14-2007, 08:56 PM

Hum... hot damn, where would the oil injector be located... on the fuel rail or b4 it?

-Thanks

**RJ Gleason** · 07-15-2007, 11:16 AM

The injector pump is located below the fuel rain/injector bodies.

Nope, they have to be in spec, or the servo will not open the valves all the way, and if it doesnt, power is lost.. It says in the manual they have to be 34.5mm..

beefey · 07-17-2007, 04:19 AM

My manual says 36.1mm --> 38.1mm. I had to tighten the nut down all the way to get that much cable. Hopefully it still runs after me monkeying with it.

Really, maybe it changed then because i know mine says 34.5mm, i just figured they were all like that.. If you want a lot of firecat info check out hardcoresledder, one whole section designated for them!
