"212x" Powroll Stroker build--UPDATED 10/19-- 28mm carb problems ):

[rg97]

update of 7-9
Searching for new valves! pm me if you have some
weve decided to not do an overbore, just have someone flycut the piston we have 3mm to fit the crank. tomorrow were going to experiment with glass bead blasting, starting with the stator cover, something insignificant...
my local honda shop had the full bottom end kit in stock, and a full top end one is on its way.
Can anyone recommend a high quality motor spray that we can paint the engine with?

Pj1 fast black. Only high temp black I will use. Comes out perfect, otherwise I powdercoat. Take a look at my 200x build thread if you want to see what the color looks like.

Update for 7-10.
Tested glassblast on the stator cover. heres how it turned out. any surfaces on the engine that can be blasted without the chance of getting inside the engine (right side case, cylinder, head, other misc.

yaegerb, ill have some pj1 on the way. its the non-epoxy one, right?
My other option is to buy a hand powdercoater ($70 on ebay) and do a self-powdercoat

[yaegerb]

Yep, non epoxy. Make sure you clean the surfaces really well with alcohol (thanks flyingw!) and spray in four to five light coats. Let it dry overnight. The results to me are spectacular.

Thanks for the tip. Would the blasted stator cover be good enough to paint just how it is now? I'm kinda an amateur on the painting part of things
I got a few questions about your engine, because I was looking through your flat track x build. Did you paint the engine when it was together or apart? if it was apart, how did you not get paint in the insides, because that's what im worried about. If i get paint on part of the bearing or anything, it'll mess it up. Also, i see that you made the head fins shiny on the edges, like stock, so is that just a light grinding off when it was done? Last one, how did you cut the holes in the sprocket cover? I'm thinking VMC or waterjet?

i used autozone degrease spary, primer, hight temp paint and then backed every peice in the oven for 20 mins at 400 degrees.

these are my pics. Ill never do it again. its just too time consuming however i was laid off for a little and figured i had all the time in the world to do it.

I also modified the sprocket cover to have it accessble like new bikes. reenforced it also so its like a case save now. making putting the chain on super easy like dirtbikes are.

right now im thinking of ditching the airbox as well, and just going to a pod filter, like this one on ebay . the airbox is just one more thing to clean, and the in-frame supertrapp has been melting it a little. Pros and cons of going to a pod filter? i know its not the best protection, and the carb will need a re-jet, but of course I would put an outerwear on it and jets are cheap. If i cant find any outerwear covers, ill just use a pillowcase or a sock
another thing i just remembered. I stripped out the rear brake reservoir body, and its discontinued, so im looking for a replacement, either an OEM that someone has, one that will work from another machine, or a custom fabbed one.

Yes, the cover is good enough to paint, but be sure to use alcohol to prep the part prior to painting. You want to make sure all of the crap is out of all nooks and crannies or the paint will not do a good job of adhereing. Yes, I painted my engine completely dissassebled. I made card board cutouts to protect the interior case bearings and then for smaller parts I just taped them off. For the shiney cooling fins I used a dremel tool with a small sanding drum and then I hand sanded with a very fine grit. After that I took the fins to my Eastwood buffing wheel. You are the first to notice the holes in the sprocket cover...very good eye indeed! I did those by hand. I used a cutoff wheel on my dremel tool to get the rough shape and then I put the piece in my drill press with a carbide bit grinding tool. After the rough shape was cut I then used small files to get the vents perfect. If you like how that looks, I can do one up for you.

no primer needed then im guessing?
btw the cylinder, right side cover, and sprocket cover are going to be blasted tomorrow
also a new timing mark cover on the stator side is on its way, the old one was in bad condition and it looked worse today after i removed it

[Mickey Dunlap]

Looking real good. Since you are only a few hours away you can come down and get mine to restore since you have the time off.

You can do primer if you want, but just put a very light coat on the part. I had to redo some pieces on my motor because the primer was too thick. All you need is a quick light fogging and then let it dry completely before applying the PJ1.

[rg97]

well hey mickey if you've got the money to pay for stuff, ive got the time to work on it!

yaegerb I like the idea of the sprocket cover, like cutting designs in it so im going to draw up a ATC symbol (like the ATC symbol or 200x symbol on my fenders) in CAD and I can throw it into the waterjet where my dad works

Powrolls site needs to be functioning again soon, because i need to order other stuff, like a high strength cam chain and other misc parts

[rg97]

minor update
drew up a quick sketch of what i want cut into the sprocket cover
Heres the picture I traced

Heres the quick draw up (of course i cant do colors with the waterjet, its just filled for representation and the look)

[oldskool83]

i would'nt hold my breath for powroll lol, however I am in AutoCAD almost everyday lol.

[rg97]

i use more inventor than CAD, but i know them both pretty well for 15
