My first Blaster MX build!
- Thread starter crxbart
- Start date
Not sure why your talking about CRXes here still, but if your putting 10gs in a B16 you should sell it now, and just buy a K swap. B series is old technology, K's are a way better platform. I've had both!
It depends what you plan to do with your car. I can talk more about this to you via PMs. Your probably building a turbo setup with that kind of money. Sure a turbo car will be faster, but they have allot of disadvantages. My K swapped CRX has serious traction problems at only 220whp on street tires. Any more power, and you'll basically just spin more. I ran a 12.9 on street tires, at half throttle through the first 3 gears. It would run 11's on slicks for sure, and the motor is stone stock, and has all the reliability of a stock engine. I'm going to build another K for that car, but down the road. There is basically no point, I just want to make it a little faster. Lets keep the CRX talk to the PMs though from now on.
Anyway back to the 450 shocks. The SMS +5 +1 A Arms I am using use 16" length shocks. YFZ450 shocks are like 1/4 to 1/2 longer. They will work no problem, and according to the owner from SMS they will work great. GT Thunder is also under 1hr away, and they told me they can re valve them, and set them up for my Blaster. So if I don't like the way they work I am going to do that. For the rear I am going to use a dual rate Elka three way adjustable. According to SMS there is nothing better for the rear, but the front YFZ shocks are very good for way less money.

Thanks for the compliment, but believe it or not, I don't have too terribly much into it so far. Shopping around, and buying used parts has it's advantages. I:I I just need to figure out what I am going to for an engine next. B-)
dude b series swaps were starting to become old tech back in like 03 when k series swaps started. b series engines dont cost that much anymore. still a good platform.
AND....to get back on topic, when are you going to have some pics of this build. i want to see what i wish i could have.

Here is my website, and my swap guide for a CRX/EF K Swap:

I have mock up pics on the previous page. I'll be welding on the frame this coming week once I get the nerfs on Sunday. I'll get some pics from that, and then it will be on hold until I get it back from powder coating. I should have it done, minus motor work by the end of the month if everything goes right.
Well I've been having some issues getting the Raptor Nerfs. I won the auction from MJUSA, and I went down there. They gave me Banshee Nerfs. So I called them up, and told them they gave me the wrong nerfs. Went back they gave me some Polaris 500 nerfs. I tried them there was no way they were fitting. They didn't have the nerfs I bid on. I was getting real pissed a that point. Now they got me a set for a KFX400. They look like they will work out. I am going to test with the front suspension on right now, and see if the tires clear. I am pretty sure they will though. I think they will look better, and have more protection than the Raptor nerfs so it is kinda a blessing in disguise. The peg mounts even bolted up, but I am modding them to move the pegs back about an inch and a half, to give me more cockpit space. I'm headed to my shop to work on that, and the rear brake mounts. I'll update once I get it all finished up, with pics.
Off to the powdercoater, well almost. I need my boss to go over, and clean up some of his welds first. Then off she goes.
I got the KLX400 Nerfs on, and no problems. The lowered, pushed back, pegs are on there too. In effort to make it a little more roomy. I have 4-5" of front tire clearance with these nerfs, and they have more coverage, and a more sweeping better look on the bike than the Raptor 660 nerfs. Also amongst all the beefing of the chassis, I also shaved some weight off too. All tabs for the oil injection, lighting system, wiring, cable brakes, oem foot guards, everything have all been shaved in effort to save weight, and clean up the appearance. Also note the brake mount welded on to the frame, and peg mount features a mount for the hydro brake pivot also. A few more hours cleaning some stuff up, and off it goes to get coated.

It's all gonna be huge. It is the super size me Blaster. 9" wider, and 4" longer. The nerfs are way inboard the tires if you can believe that. Like 4" a side in. I am really happy with their fit on this chassis. I love them. I can't wait to ride this thing!
Dude, I am so on the fence on allot of things. I am contemplating having my Canadian friend get me all the parts I need for a DT200 cylinder swap, but there is no, or only vague info on the swap. For now, I plan to just rock the Blaster motor with my FMF pipe, until I feel I need more powa! Which should be soon, I am sure. The YZ250 swap stays very close in mind. I want to build a high horsepower Blaster motor, but I hear the reliability suffers. It just seems so easy to make power with the bike motors, and have stock reliability. The lack of counterbalancing is the only thing keeping me away. I think for now, I am going to get it done, and race it with a stock motor, and if I do a YZ swap it will be next winter, but if I build the Blaster motor, or swap the DT200 jug, that might go on sooner than next winter.
check the rules where you race too... the 200/ blaster class originated with the 200x 3 wheelers (ama wise) , it got political when people started sleeving down 250r motors to race 200, so the rules where changed to air cooled 200. as for reliabilty, properly built and maintained, they hold together. neglect a built motor a little bit and it won't be happy. the dt was rated at 30hp by yamaha which probably translates to 25, I have seen the cylinder, head etc theres better technology in the la sleeve/ct cylinder. for the DT you will need, cylinder, head, powervalve servo, complete stator and flywheel, cdi, rectifier battery, then have the cylinder ported, clutch cover and waterpump assembly, have a gear made to drive the waterpump (the dt uses a dfferent clutch basket and primary drive ratio and gear cut,) not trying to discourage you, just letting you know it more than bolting on a cylinder and hanging a radiator.
Wow, very good info on the DT swap. That's probably why no one ever finishes the swap. I am not daunted. I am just weighing out my options trying to make the best choice. Motor swaps and what not are no problem where I'll be racing. They killed their Blaster class. So I have to run open class now. Maybe I will keep it Blaster IDK. I just googled CT, and was looking at their cylinder setup. It has me very interested. Their 40hp dyno on a stock stroke 240 is very intriguing. I wonder how it would run with a 4mm stroker? Is there still an AMA Blaster class? does it allow anyone that isn't 15-17 race?
