FullSize S10 Bogger/Mud Racer

[toomany]

It runs!...for reals this time!

Mufflers, clamps, hangers, and vacuum caps came in today while i was at work. Had ordered a stick of exhaust pipe at the local Napa while I was there last time, so I picked that up on my way home.

Muffler choice was a pair of Hooker Aero Chambers. Could have gone with a more expensive/free flowing one, but these flow decent and don't kill a ton of power like a Flowmaster would. Went with 3" in/out as that was the header outlet size.

Drivers side was easy, straight shot from the header back. Passenger side I had to make a bend with some left over 2 3/4" exhaust pipe I had. Pretty standard bend as far as square body exhaust goes to get around the transfer case. Each muffler has about 16" of pipe after it. Was too caught up in what I was doing to take pics. Next time I'm out there or have them off I'll get some.

When I sold the truck a few years ago it had a little bit of fuel in it. Having sat for a year plus, there was no way it was going to be any good. A while back I drained what was in the tank out. Most of what was in there was very watery. Not sure how it got that way, I figured it'd be a good idea to flush everything out. Put 6 gallons of fresh in and ran it through the pump/line/regulator. I pumped it into the same can I used to fill it, so I'd have an idea how much was left. Got a little over 6 gallons out and it all seemed like straight gas (it wasn't).

That was a day or so ago. Thinking I had a full can of 93 to burn up, I topped off my R6 with it. Maybe only used a gallon or so (bike only hold a little under 4). Well, about 3 miles down the road the bike died. Turns out what was in the can was enough to dilute the bikes gas to the point it wouldn't run.

This had me second guessing what was in the tank on the truck. So I flushed everything out again and put another 6 gallons in. Thinking all was well I went to fire the truck up and break the cam in. Turns out, that stuff was too watered down too. Motor would try to run, pop and hit a couple times then crank and crank with nothing.

Fed up with that I pulled the line off the carb and both float bowls off. Stuck a hose in a gas can and the other end on to the fuel pump. Flushed evrything out again and tossed on a new filter.

With some real gas in it finaly, motor fired right up and settled into a nice 1200rpm idle. I cranked that up to 2600 and left it while I topped off radiator, power steering and transmission. Sounded great and reved clean when I'd open the throttle. Sounds like a few lifters were ticking. Usually I go through them all anyway to reset lash.

Didn't quite get to the 20min mark like I wanted. Ran the gas can dry around 16min in, which I'm going to call close enough.

I planned on getting rid of the Blazer tank that was in the truck, so I'll probably start looking for a fuel cell now. Next time out I'll pull valve covers and go over rockers, change the oil/filter and hopefully take it for a test spin around the yard.

Picked up a new transmission pan gasket to replace the leaking one that has been on there since I put the TCI pan on a few years ago. Put a new filter in while I was in there. Fluid looked nice and red/clean with not much stuff in the bottom of the pan.

Put some caps on the open header evac pipes. Since they are in a weird spot, I welded some nuts on them so I could get in with a stubby wrench. I've got the rest of the parts for the evac system, if I decide to use them I'll have to pull the mufflers off.

Went through the valves today. None were particularly loose. Guessing that is just the sound of these lobes (noise didn't change after).

Fired it up and took it around the yard a little. This thing rips compared to the small block. Converter works much better now too. Still have a little bit of tuning on the carb, along with timing. But for the little bit I have done so far, it runs awesome.

Ordered a fuel cell and some plumbing parts. Going to try getting the K5 tank out this weekend (been running it on a hose shoved into a gas can for now).

Also think (actually know) I've got a caliper hanging up, so I'll get a new one on there.

thatched the lawn too...

Grabbed a couple new calipers. At $20 each it was hard not to get all 4. That excitement quickly wore off as I was grinding them down for clearance. Shot some paint on them, didn't take too well as they were pretty warm and sort of dusty still...then the brake fluid did a number on them too.




Fuel cell came in today. Went with a 15 gallon. Pulled the old tank out last night. I don't think my pickup was all the way to the bottom because there was still a good 10 gallons left in it. Plan is to mount it pretty much where the old tank sat. I have some heavy wall square stock I'll use to make some rails for it to sit on.




Stuck the front end back on tonight. Had to fix one of the plastic ends on the bumper. For some reason the last guy scrapped the inner fenders after he pulled the clip. I've got a few ideas on how to box it in some to keep the water out.

You should see the spot up by the house where I really got on it.

Been slacking a little on the updates for this.

Got the fuel cell mounted. Made a frame with some 2x2 square stock. The cross piece between the two is right in the middle of the edge and the sump. Added some foam where the cell contacts just for good measure. Also pulled the foam out. Heard lots of horor stories of the name brand stuff failing, not about to trust the cheap ebay stuff.






Lots of clearance. Will probably cut some more of the box out. Mostly from behind the wheels.




For vents, I just ran some hose off of each fitting on the top with an inline fuel filter to keep things from getting in.

Managed to get it out for a little more run time today. Took it to a place called "The Mounds". Been there a few times with the 4 wheelers, first time with the truck. With the hot weather we've had (been in the mid 90's for about a week now) it was pretty dry and no one was there. But it was a chance to get into an open area and really open it up.

For the most part the truck ran great. Has a small flat spot where the secondarys come in. I've got a quick change setup for that spring, so it won't be too hard to dial that in. Didn't mess with jetting at all. Truck started running hot after about 30min. Only one of the fans is running right now, hoping once I hook the other one up that it stays cool.



Plan on taking it out this weekend to the local dirt drags. Probably going to run in low range as it leaves hard and the course is only 180'. Before that, I've got to get it washed, check fluids, probably change the oil, take a look at the plugs and toss a fresh set of wires on.

 

[toomany]

Changed the oil/filter. Oil looked real clean still. I like to change it again after running it for a couple hours after the initial break in and first change. Unless I really water it down, it will probably stay in for a decent amount of time now.

Hooked my other fan up. This was as simple as running another wire from the relay bank in the cab. Makes a little noise until it gets up to speed, but then it's quiet. We'll see how well it stays cool now. If it still gets hot I'll look into a higher flow water pump or possibly a remote/inline pump to boost flow.

Pulled plugs and wires off. The plugs looked real good for a fresh build with no real jetting work done. A tad rich if anything. But I don't have a lot of full throttle time on it nor have I done a proper shut down to get a good read on them. #6 was wet and looked like it wasn't firing all the time. I had seen a few stray sparks coming from the boot on that side. Because of that, I picked up a set of new MSD wires for it. Nothing special, some of their 8mm Street Fire series. Put so.me decent wire separators on them too. Got the cut to length ones, the drivers side came out ok...a few are a little longer than I was going for. Passenger side came out perfect. Might pick up a couple more ends a trim down the long ones.

I must have had more than a couple bad wires because the motor fires up way easier and runs much smoother now, not that I thought it ran rough before. It's much more crisp now.

Bump

Been using this thing a few times a month. Either at comp bogs or just taking it out to the ORV parks.

Been running great with no major issues. Burned a plug wire last time out, have a new end as well as some heat sleeves to go on.

Broke a front U-joint. It was some bastard combination that took two joints and modification to work. Replaced the yoke on the D60 with a 1350 one and got a standard joint.







When the joint broke, the driveshaft loop kept everything safe. No damage to the trans pan or oil pan. Pulled the shaft and ran around in 2wd the rest of the day.


Fuel pump had been showing signs of trouble. Pulled it apart and one of the magnets had come off the case. JB welded it back on. It worked, but I didn't trust it I stuck a new pump on. Went with a Summit brand, basically a Holley knock off. My extra rebuild kit I keep on hand will work in it too.

Messed with the carb/timing a little bit. Got the timing where it's happy. Carb....still needs a little work. Has a small stumble when you first get into it. Put a larger 50cc pump on, seemed to help. Going to try squirter sizes next. Normaly I'd try pump cams, but the larger pump only has a couple of them available. May have to drill the throttle blades for more idle air. It's rich at idle and I don't want to open the throttle anymore than I have to (uncovering transition slot). Mixture screws are only doing so much for me. I also don't want to put too much effort/money into this carb when I know I could probably get more out of something better.

Removed the bypass hose from the water pump/intake. Before the motor would get hot, not over heat, but hotter than I'd like. Came to the conclusion that running the bypass hose and no thermostat was only sending some, but not all, the water through the radiator. Pulled the hose and capped the outlets off. Now the truck runs at a constant 160 with just one fan running. Even without the fans on it doesn't heat up as much or as fast now.
