My Baja Heat Rebuild! Paint and powdercoat inside!

#1
Hi Guys,

I figured I am turning the corner on my second Baja Warrior/Heat/MB165 now and I should make a project post.

So of you may recall I had powdercoated an assembled GX200 block with head a matte black in the Honda/clone form. This is the bike it was planned for.

Background:
I found a BAJA bike on Tallahassee craigslist, actually, I had seen it on CL for about 2 or 3 weeks, but finally I decided to contact the seller. This BAJA was in what I would call a normal state for its age. The fake tank was broke and removed, however I have it, the seat has been broken and doesn't securely mount to the chassis, and the paint looked a little rough. I paid $175 for it, and gave me something I could strip apart and make my own, unlike the first Baja Warrior I purchased, which was in mint condition for $200 bucks.

The Process:
First, after disassembly, I want to go through the engine, removing un-need parts and stuff. The thing I like about the BAJA engines, they don't have the oil sensor and there is no hole to fill. Since I race go kart also, using the clone gx200 engines, I have more than enough performance parts, so with this build, I used a set of 10.8 springs, a Gecker BSP racing cam, and a head than was cut to low and brings the engine to roughly 25cc. I also had a Gecker top plate, which I powdercoated matte black with the heat shields to match the motor, which I also powdercoated matte black. I have ran the engine now for about 30 minutes and haven't had any problems, and the motor really stands out on the bike since it got a new fresh coat of paint.

Since every BAJA I have seen like this has a black frame, I decided to go a different route. My favorite color is orange and I utilitze it on all my racing karts, so I thought a orange frame would be ideal and really help make this bike stand out. I decided to use the old spray bomb paints. I have a orange from Valspar I like apply probably 6-7 coats over a 2 week period. I think applied 3 to 4 coats of Valspar Gloss Clear. Now that this is cured, it does make the bike stand out, and wiping oil or dirt off is too easy. (Later, I also decided that since the handbars where about 2 inches longer than what would fit in my PC oven, that I would paint them orange to match the bike, that was a good plan, as the stock chrome on the bars had started rusting.)

I also had to decide what to do about the fenders. I didn't want to keep them a gloss black, since the engine is matte, so I also painted them a flat black. On the rear fender, I added a solid, 1.25" orange stripe down the entire length of the rear fender, and offset two half-inch chrome stripes to set it off, and to tie the chrome factor chain gaurd back into the bike. Having my own vinyl cutter allowed me to play around until I got a combination I liked. At first, I had a big orange stripe, but it was difficult to get it to lay down on the curved fender, the small stripes solved this problem and turned out better.

I left the front forks as they were, the silver does, in my opinion help brighten the bike and make it look as it should, I was afraid if I blacked-out the front end, the bike would lose some pop, so I have left it factor for now, as I did with the rims too. Originally, I was going to powdercoat the rims either Chrome or Flat black, but the silver has grown on me for the time being, and one of the rims had some rust, and I don't have a sandblaster so I decided to wait until I wanted new tires and buy new rims as well. I think all and all, it also helps make the bike look good and not two-color.

Assembly:
After re-assembling most of the bike, I decide that there wasn't any header or exhaust system that fit my vision for this BAJA, so I went through my collection of of Animal headers, and found one that had been bent about 4 inches up in the middle of the curve coming from the flange, I cut the bent section off and used a hole saw in my drill press to make a 1" opening in a gx200 header flange cut off a broken BSP racing pipe. After carefully tweaking the pipe and rotating it, I found a combination I like that kept the exhuast up under the bike and allowed it to exit point down, and not out the back. Plus, I can add a RLV muffler if I need to with this pipe. After tacing the pipe to the flange, I ran several welds around the pipe and the flange, and even made a bead around the inside. I have a MIG welder, setup for flux, but I have to run the welder off my generator, and my generator struggles, so I tend to go the extra mile to ensure I get a solid weld. After cleaning up the flux mess, and filing out the inside of the pipe, I of course decided an old rusty pipe wouldn't do, so I decided to try some header paint. I've never used it before and I wanted to not have another orange or flat black piece, so I went with the silver finish they have. I like it, and i think it looks well with the bike where it is. This header sounds pretty good, I've tried to video it running, but I haven't been able to get a good recording yet, but I'll work on that.

Items to be Addressed:
I need a fuel tank, I have ran the bike a couple of times with the fuel line plugged into my gas tank. I just haven't been able to win a good tank off ebay yet, but I'm trying.

I was going to order a new seat from Monster Scooter, but now they don't stock the all black seat, so I am going to try and see if I can make my red/black seat work and use vinyl paint on the red part to get it all black.

I have the light, and it works, but with the rpms of this bike, it won't last long, so I would like to make the electrical work and be safe for the lights.

Investigate new gearing at some point.

Foot pegs were original, but broken. Looking for a good set for a harley or something, but doesn't have Harley on them and doesn't cost me an arm and a leg.

Future Plans:
I'd love to build a sidecar. My wife recently got me a "Affotable Bender" and I would love to use that as my first project.

My other BAJA is actually not bad, I don't do alot of off-roading, but it doesn't bother me if I hit a bump here or there... I wouldn't mind installing a springer seat, just dont have the funds for now.
 
#5
I decided to make a new BAJA Warrior 196cc logo... I think this will look good on the chromed factory chain cover... :) it's a little no long to fit on the pullrope cover, but I can make a smaller one.

You could make a spring seat just by grinding off the original bolt on the bottom of the seat, welding a longer one on, then find the appropriate spring to slide on the bolt, then tighten it to the frame using a locknut so it cant stay loose enough to allow the spring to work. Just a thought, I never got around to doing this to my bike yet.

Nice color combo choice, and the logo looks sweet also. That's a good idea with the header, did you make that yourself? I made one just a few days ago that is kinda similar t yours. Nice work. The sidecar would be neat, are you gonna make it detachable?

You did a nice job on that powder:thumbsup: you don't cook in that oven do you?:doah:
Whats your set up?
I'm placed in charge of the powder coating set up at work, I've been doing it every day 8 hours a day for almost 3 months.....I'd like to think I've progressed from Novice -> semi-professional; I don't know every thing, but I'm pretty deadly:drinkup:

Yes, I'm actually quite the hobby level powdercoater... I use a propane oven at that, it actually does a really good job compared to the old huge toaster oven I had... lol... I have it setup to run off 20lb propane tanks.

My gun is a Sears Powdercoat all in one unit, lol... but I have been working with it over a year now, and I have gotten it where I can do second and third coats, so I'm into the crazy clearcoats with sparkles now on some of my racing engines, and the translucent colors are pretty bad to the bone as well...

The problem with my seat is both the front and rear mounting tabs/bolts are completely gone, and much of the plastic around them has been destroyed too... so not a lot to work with.

I was just outside and had her running... man it sounds good with that pipe... gotta get a good clutch cover too, the plastic one is junk, I wouldn't mind converting it to the new style metal cover and jackshat like on my black BAJA Warrior (a real BAJA Warrior)

My hopes are one day to yes, have a detachable sidecar, I think it would fit nicely with this style bike. And I made the header myself from a bent up Animal header and a gx200 flange. I have my dad to thank for the header, he broke 4 ribs in that wreck when he got on his lid in his kart, that was back in 06.

Very cool, I have yet to get my hands on some fancy power like that, but I will,mark my words:gunsmilie:

You should try some high temp tape, it purple and can stay in the oven all day long, it's a lot better than pealing off the masking tape with a pair of tweezers:eek:ut:

I heard that, actually, most of that is not masking tape, I actually used my vinyl cutter to make those masks using a blueprint of the gx200 engine I found online. It just happens that I used blue vinyl, the one place I used masking tape was the exhaust port, everything else was a sticker cut in my machine...

Well, in the interest of moving the project along, I ordered one of those 3 liter motorized bike tanks off ebay tonight and will probably be in here next week. I just can't make myself spent basically 100 bucks on a decent looking sportster tank or something off a street bike. So this will do for now, I also repaired my seat, we will see how it holds up, I'm going to get some vinyl paint from Dupilcolor and go all-black.

Only thing I need to finish this off is a set of foot pegs.

Who did you buy your tank from on Ebay? There is a seller "boygofast" that I got the 4 liter tank from for under $50 shipped. They have the 3 liter chrome tank on sale for $36.09 and the painted one sells for $23.74. I think they are out of the painted 4 liter tanks?
 
#13
That is who I got it from, I decided to get the 3 L since I wasn't quite sure of the size and figured since 3 L is just over 3/4 gallon, it would be fine for now, until I have the tank I really want installed, and i can use this smaller tank down the road.

But I got the 3L, for like you said, 23 bucks or so, and I have 15 bucks shipping, about 40 bucks. I went ahead and got a black one, figured that would match my scheme, plus, I can powdercoat later if I desire.

Update:

I had to push aside this mini for a few weeks, but I got it out this past weekend and rode it a bit, I guess I will need to put the muffler on the header or get a different exhaust setup because that thing is loud... I took off down the street real quick and I got all the neighbors' attention... that was the first time I really opened her up, still has the stock gearing, so I need to fine tune that for a bit more top end, but it rides good and looks good...

The engine has a cut head on it, one of my racing engines had a head that was cut too much and wouldn't pass the CC rule, so I installed that head on the motor when it was powdercoated and it does pick the motor up somewhat, and the fact that I used a stock .009 head gasket instead of the thicker .040 gasket originally there, I'm probably down to about 22 cc...

I installed the 3L tank and it looks great and was a good call, however, I could easily have gotten a 4L as well, and I mine and use this 3L on the next bike I have sitting... I did have the motor setup for a fuel pump, and the valve cover was drilled and tapped for a pulse line, but for now, I'm running gravity feed from the tank and I installed a plug in the pluse line. Just got to remember to turn off the fuel valve on the carb and not flood the crankcase.

Engine is running great and shows no issues with the PC job. It does have a AKRA BSP racing cam I had laying around in it, but I'm running the weaker 10.8 springs so it does help keep the rpms down.

Overall, it turned out great, I haven't really rode it alot yet too because the paint is still a little soft, but for there most part now it is really looking sharp.

About 3 weeks ago, I had a complete Baja Heat given to me. This will be my next project. I got it home and found that the fuel valve was open and about a gallon of gas was in the crankcase, and had been there a very long time. The motor is very tight when spinning over, so I'm not sure yet if the rings have rusted up or if the rod bearing has start to go since the fuel has washed down the cylinder and all the bearings... This may just become another spare racing parts bike as far as the motor goes. We shall see.
