I buy mine locally from Seattle pottery supply, I usually order it by the ton or half ton, so its pretty cheap. Most ceramic supply places will have some, usually in 50 or 100lb bags.

If I was going to do it again I would use the wax. it had been so long since i made my tailpiece i forgot that step of the process. I think i would also try sealing it with some primer/sealer and sanding that down first too.


These came today, the faces I designed are looking sweet! i cant believe how lightweight they are compared to the stock ones. sorry for the crappy cell pic. camera was dead.

I hope you don't mind that I saved your road trip pictures to my hard drive for a little inspiration. You are living my dream, good sir.

Wishing you all the best luck working on this bike, I'll be watching your progress with great interest...

Also, I like your taste in boots (and arachnids).
Bikers are a rare breed.
Harley riders are a dime a dozen.

that underbrace will make a big difference in your handling.esp,mid corner bumps when you are on the throttle.

slowly chugging away with progress on the frame.


really happy with the way the swingarm turned out. It looks strong, and aesthetically it looks pretty good to me. I get better pictures once I have the bike back at home.

finally tore the engine apart again, cleaned it up and got the cases back together, This time WITH the clutch basket. Oh that? just a morawaki points cover B)

Decided the casting marks of these handle bars were a little to chunky, cleaned them off. Thanks to Leon for machining collars for the clipons to fit this bike. Cant wait to toss them on the bike.

i'm slowly plugging away at the engine. but i hit a small snag. I cant figure out which ring is the upper piston ring on the new 1075 kit. there is a drawing of the cross section of the rings and how to tell, but the both just look square to me. one seems to have the slightest bevel on a corner, but i cant really tell. anyone used one of these kits before? any tips on determining how to tell?

I also took apart the carbs, they are now soaking in pinesol.

Per FSM, stock rings are installed with the "N" mark on top; ring with beveled outside edge is the top ring; ring with unbeveled notched edge is the middle ring.
But would defer to installation instructions from the specific manufacturer of the kit at hand.
Such instructions might be available on-line.

And let us know of results with the Pinesol, as several success stories have been reported.
It would be nice to see your results, and hope to see an "after" pic.
The currently available carb dips seem to be getting weaker and weaker.

The "boiling" method has mixed reviews, whether using plain water, or lemon juice, or vinegar.

Experiments with other soaking mediums have sometimes resulted in damaged carb parts, such as corroding the throttle slides.

Good Fortune! :)

I will definitly post an after pic of the pinesol results.

The pistons are 1075 Wiseco. There is a diagram in the kit explaining on how to identify the rings and how to install, but the profiles look identical to me. maybe i'm not looking at it close enough. It was pretty late when i was trying to figure it out. Hopefully I will get some time tonight to look at it again.

i'm thinking that as long as the ring grooves are the same dimensions that they are interchangeable.

maybe someone else can chime in with something for sure.

So i called wiseco and figured out that the silver ring is the top ring, black is the second ring. Went to put the second ring on and.... SNAP. so now i'm waiting for a new ring.

I did bring the bike home yesterday, the sub frame is mostly complete, still needs the shock mounts, and it needs the rest of the bracing finished up.





Some beautiful welds.



I put the new handlebars on. They're pretty bitchin. Need to clean up the triple clamp now.




I also put in some new steering head bearings. As per usual the old races where a real PITA to remove, but i got them out and new ones in. I love homemade tools.

I found a steel one at a bike swap for real cheap, but thanks for looking out.

I got the replacement piston ring ring today, I'm going to attempt this again tomorrow, but I'm a little nervous about putting the top end together. Ive never done this before and everything I have read says that is crucial to do correctly, so Im going to put my piston ring end gap figures up here. Hopefully someone will notice any errors if i make some, and hopefully avoid an expensive mistake. (probably will anyway) :sick:

72mm / 25.4 = 2.83464567 inches

TOP RING
2.83464567 x .0045 = 0.0127559055

BOTTOM RING
2.83464567 x .0055 = 0.0155905512

this came in the Wiseco 1075 kit...

i have slways shot for around .018 end gap and have never had trouble with the rings getting hot and "butting".they always make good compression and don't smoke.

hopefully someone will chime in with some better info.

Yeah i saw a photo of that tool on this site and made it. I think it was either plummen's or your photo. :lol: I can't take credit for the welding. that is the handy work of Eric Waunch of High Performance Welding in Bothell, WA. he has been squeezing some time in on the bike here and there for me.

So here is my carb cleaning experience with the pinesol. I used it straight and soaked each carb for a couple days, I noticed that the pinesol in two of the buckets had turned cloudy on day three, i figured it was because they had the dirtiest carbs in them or something.I kinda forgot about them, but on my way through the garage i remembered them and dumped them out of the pine sol. They looked pretty good, but still kinda dark.

This is where I screwed up. I should have immediately rinsed the pinesol off. But i didn't, and it turned into a oily film on the carbs. :pinch: Also the two buckets that got cloudy developed white deposits on the carbs.

I tried using solvent to remove it but all it did was remove the oil and left the film. I tryed soaking it in parts solvent hoping it would dissolve, all it did was rust some springs and a couple screws. :sick:

I then found this THIS and decided to try boiling them in lemon juice, because i screwed the pooch bad this time.

I boiled them in straight lemon juice outside on my camp stove. It has a strange smell that is not that great. I used the tray in a carb-dip can for the small parts. I boiled them for 30 minutes them immediately moved them to a pot of boiling water and boiled them for 30 more minutes. I then blew compressed air through all the passages.

It cleaned them right out! I had to do the ones with the white deposits on them 3 times till i was satisfied, but they are clean as a whistle.

The process turned all the parts dark grey and flat, and the pinsole stained the irregularitys in the castings. I think it may have pitted them slightly as well, but it could be like that from the factory for all I know. the lemon juice turned all the brass parts copper in color as they oxidized. The pot metal parts faired the worst. It seems as if the lemon juice removed a layer of paint from them, they are slightly pitted, just a bit rough not too bad. is this bad?




Also the lemon juice removed the rust, I was very impressed with this.



I bought a soda blaster and soda blasted the everything, and washed it down. They have a good shine on them now.

I started reassembly but forgot to buy a couple things so they are on hold for a moment.

On a different note, Turns out the frame is bent, possibly the swing-arm as well. Took it to Wasco Frame Repair in Tacoma a couple of weeks ago, he should be finishing up with it soon.

I did get the rind gaps sorted and the rings on the pistons.

I got a little derailed after my retardation with the carbs, but it all worked out and Im pretty happy with the results. I feel revitalized on this project, and I cant wait to get the frame back and re-do all the body work including some custom side covers!
