    FIRST BIKE EVER 1982 KZ440 LTD HELP ME!

    Best of luck man! If you need any original parts, let me know! I just finished a kz400 build. If you want to lower it, i have a set of forks that are 1.5" shorter than yours! The later models were taller.

    KZ400 W/Keihin PE28's - Stumbling at "cruise"

    Jetting question! My bike idles great, and pulls great throughout the entire rpm range. However, when the bike is cruising comfortably, it stumbles. This happens at any speed. It pulls phenomenal, but it doesn't just "cruise". Plugs are showing a rich condition. Carbs are Keihin PE 28's. 100...

    75 KZ400 Break it Loose!

    Thanks guys! I used an HVLP for the base green coats, but everything else was done with an airbrush. I have plenty of experience painting helmets - this is the first full bike I've done though.

    75 KZ400 Break it Loose!

    sorry i missed this! There are a few keys. One - use the right tape. Use a good tape intended for automotive paint masking. Second, back paint before laying down new color. If you're painting a black stripe on a white tank, mask of the region you want to be black, then hit the area with a coat...

    On the stand, outside, for final assembly. Bottom half in. realized I had lost one of the sleeves to hold the cylinders in place... $10 shipping for a 20 cent piece... Plate mocked up in the tail Tank and tail. Starting to look real again! Totally underestimated how long running...

    75 KZ400 Break it Loose!

    Thanks! Wanted to drop an update of where I'm at. Moving behind schedule, but that's okay. I've got the rolling frame put back together to see how everything fits. May need to lower the front a tad. Some of the lines aren't coming out the way I had anticipated, so I'll be revisiting (headlight...

    75 KZ400 Break it Loose!

    Finally had a chance to keep things moving. Found 1 over shocks for the rear. Made a plate for mounting the new (smaller) headlight. Welded up the tail section with steel tube. As the fiberglass cowl will be squared at the rear, so is the tail section. Frame taped up for glassing...

    Looking at 2" higher front and rear. Also started to set up the Keihin PE's, love these little guys. Rear section mocked up in photoshop. Will end up laying it out in fiberglass.

    75 KZ400 Break it Loose!

    Alright! Stock carbs are 95% rebuilt after a couple modifications down in the bowls. I couldn’t source any nitrile plugs to cap the slow jets, so I tapped the top ¼ of the tube and threaded in a ¼” brass plug and slotted the top. I also couldn’t find main jet springs, so I used E clips and a...

    Engine inspiration thread!

    This thread inspired me to do my engine up right on my rebuild, so here's the final product!

    75 KZ400 Break it Loose!

    Okay! I've got the engine 90% complete! I'm going to wait until the engine is in the bike for the final time to install pistons/cam, as I think it will be easier to install the engine into the frame staring with only the case, then build the engine up once in the frame. I might need to replace...

    75 KZ400 Break it Loose!

    More painting! Side covers have all been painted (still need to be cured). Started cleaning up some of the aluminum accent pieces too. Used 600 grit, scotch brite, followed by Flitz metal polish and they're right in my wheelhouse. Not too much shine, not too dull either. Hard part is going to...

    Cases painted. Now to decide what else gets painted/polished. That's the hard part!

    75 KZ400 Break it Loose!

    The impression I had gotten (after reading various other threads) is that if you let the paint cure for a full day before baking, the vast majority of off-gassing has already happened, so the fumes are quite minimal. I'll probably test it out for a minute or two and keep a close eye on it. If...

    75 KZ400 Break it Loose!

    Thanks for the advice everyone. While leaving the engine bare was clearly the most durable way to go, I got to looking at the "show of your engines" thread, and the coordination between painted/polished/bare parts was just magic to me. So considering that, I'll be painting the lower end, and...

    75 KZ400 Break it Loose!

    I'm at the point where I can't decide whether I want to leave the engine bare, clear coat, or paint. After all this hard work getting the engine clean (scrubbing by hand, blasting is out of budget ((baby on the way)), I'd hate to have the engine just get dirty again once it's up and running...
