Hi Jess, I'm riding a 1990 DT200 and my son has the earlier (1986?) DT200 engine in a Blaster From this bike: The motor out of the 1986 DT200 is nearly a direct swap into a Blaster (still lots of problems!) . The 1990 motor has some major differences that will make a more complicated swap...

Interesting how things go around. I picked up a 1990 DT200R and I daily ride it around the city and beyond: Not as powerful or as off-road capable as a KTM EXC, but much more acceptable on city streets. Unlike the Blaster, the reed valve feeds directly into the crankcase, no window in the...

It should not need a lap after 5 hrs, but here is how you do it. IF the head sealing surface is not machined below the fin area: Lay a sheet of 240 (or higher number) grit abrasive paper out on a sheet of glass (flat surface) tape the abrasive paper down and move the head around on the paper...

Yup. Sealed shut at the factory, no practical way to open them.

I have one on a Blaster I bought last year. Engine was noisy, sounded like piston slap so I pulled the cylinder to have a look. Piston clearance was acceptable but it was obviously a very cheap quality piston in a stock bore Chinese cylinder. Put it back together as is and still running it...

Yes, look like the parts I'd use. The gold bracket on the caliper gets removed and thrown away. I can use just about any Master Cylinder and all you need out of a hose is the right length and bolt size, AS I RECALL. AWK's setup uses different caliper and mount, but is a similar set up. I do...

Hi Scott, someone has trimmed the cable mount (that I use as an M/C bracket lower mount) from your frame. Compare inside the blue circle in picts: I also weld a short tab onto the brake lever to connect the M/C rod. From experience, the shorter the better. Make the cylinder bracket quite...

I cannot tell you from here Scott. It has been a few years since I put this stuff together. It typically takes some experimentation, which is why folks charge more than the sum of the parts. If there is not enough profit from selling the completed kit, folks stop selling them.

Sorry Scott, I originally did not see the links. I cannot vouch for the quality of this seller, but yes, that is the right caliper to use. Remove the gold coloured slider frame and the silver colored park brake cap and bolt it to the solid adapter I made up with the park brake cap screws. I...

Do not use the K&N air filter if you are running off road. Too much dirt gets through. Think about a head mod as your first and possibly only engine mod. Even before and instead of a pipe. The 400EX shock is recommended, don't bother with the Banshee shocks unless they are free. ATF is a fine...

Hey Tankbuster, Awk was pretty open about what he used for parts and what he supplied in posts to this site. His braking system has a bit more mechanical advantage than mine, eg, it takes less toe pressure to lock on the brakes. I'm in the same boat as AWK, too busy to sell parts, but I will...

Yes, that will do it. My son built the DT200 powered Blaster. We had no wiring diagrams, he just transferred the wiring over from the bike to the quad. I'd appreciate prints if you have any.

Hey Tim, Rubbersalt is/was active on other forums but has not been on here since Nov 2016. The DT200 has a better curve than the Blaster, but requires a different pickup. No, it does not require a battery for the ignition but we found we needed a battery for the powervalve controller. I did buy...

This is what we are looking for in a 2 stroke timing curve

Zappy CDI coil fired adjustable ignition. similar to previous circuit. these fire directly from the coil, don't use a trigger device. There are problems with timing accuracy over temperatures.
