So it begins another Cj 360

Job #1 is to ensure everything is in proper working order. Anything you do to an engine needs to be done to a "healthy" engine.
Easiest mods are an increase in bore. +2mm is fairly common. That'll bump your displacement up to 378cc. GS850 pistons are a straight swap. Machining usually costs around $150. If no GS850 pistons can be found, you can have a set made. Not usually cheap, but increasing the displacement on a 360 is probably one of the most cost effective (hp per $, not necessarily cheap but good value) performance modifications you can make.
Compression can be raised by skipping the bottom gasket and using Threebond (or similar) during reassembly. Make sure to use premium fuel after this modification.
In both cases, you'll want to check all the clearances after the work is done.
If you decide to do both options, you can expect to see between seven and ten horsepower.

Im not trying to be a smarty pants...I have a cb360, I love her as is, She has a 17 tooth drive sprocket, She cruises at 65-70 real nice, Ive done 80 on her to pass vehicles...If you want to increase hp. and your parts are already on the way. I think you should build it, sell it and pick up a 750...that seems to be the easiest, to me anyway.
My brother has his CB400four for sale in Memphis. Its a bit quicker than my 360.

I might do that I may not I dont really know yet what ill do once its built.... I have a VStrom as well and I really like just having a little bike to bop around town on but something thats easy to take on the highway as well.... I think my dads about to pick up a 750 though so yeah...
I did my cases in Simple Green, followed with soap and water.
Any citrus cleaner should work on the cases. If there's something on the cases that doesn't come off with basic cleaner and soap and water, you may want to bring it up. The cases basically exist to keep all the parts from flying out and keep the oil in. They're not really exposed to much in the way of heat (when compared to stuff like the jugs and head) and so the oil and grease never really gets baked in. The dirtiest part is usually right around the exterior of the countershaft and nothing special should be required to even clean that part.
You may need a scraper to get the old gaskets off and you can resort to 400 grit sand paper, if needed, but be gentle.

Yeah. Simple Green (or other like cleaner) with a plastic brush, followed up with soap and water will take care of 90% of your cleaning needs on a bike. For the jugs, do the same thing, but you may need a tooth brush to get in between the fins.
Also, be sure to wipe down the inside of the cylinders with a clean cloth followed by a spray of WD-40 to keep the rust at bay while you have everything apart.
Air dry all the parts (or in the oven on the warm setting... don't exceed 200°F on this stuff) and then wipe down with denatured alcohol 30 minutes prior to painting.

be sure to get ALL the bolts out...LtGeorge said:

I found these two Ninja A-Holes hiding and giggling at me.
sweet oily success. Thanks PJ, Sonreir, frogman, smLouie, mitchellsk, &everyone
BTW heres how I cleaned the jugs...The old lady was delighted.
Also, as soon as dishwasher stops. Be there ready w a clean rag. And dry the cast cylinder walls a quickly as possible. They will lightly flash rust. Nothing bad... its scary looking at first. But it will wipe right off.

Yes finally.... after feeling like that scene in Zoolander where they try to get into the apple comp I found two ninja bolts hiding out, trying to act like what i thought were drainplugs. Ill have pictures up later today but im planning on getting the new tranny assembled and mocked in, have to wait on my kick start shaft, gaskets, clutch plates and engine bolts then ill be reassembling. Still debating wether I want to bore it out, If I do I will have to increase the piston size correct?
