Those pieces turned out amazing. Such attention to detail on your builds, too good!

Thanks! Trying to limit it this time around, going after a long term low-maintenance build so only NLA hardware is getting redone.

OK, quickly back to the seat for a bit. Stopped by MTZ customs, some really great work on custom car interiors but I'm afraid they might just be beyond my budget. Plus, cost would only get worse since they said they'd have to order the heat stamped vinyl I want for the top. So I decided to give it a go myself, promised the wife that I'll replace her sewing machine with a better one if I broke it. Found the vinyl I was looking for on ebay, but their stock pix didn't show the filler underneath

I REALLY don't like that caterpillar look. I cut out a sample and just hulked the padding apart

Turned out exactly how I wanted it to look, pleated but flat

Have the matching unpleated side and belt vinyl with it, just need to wait till my wife can order some heavy duty thread and needles.

Also, VJMC magazine subscribers, look for my detailed piece on polishing aluminum in the current issue

That was the most asked about question followed by DIY zinc plating.

Quick Q: Lesters don't need rim strips do they?

DH · « **Reply #255 on:** February 16, 2016, 08:36:33 PM »

Raf, Have you considered advertizing/doing zinc plating? If you had enough exposure and word of mouth from
satisfied customers, you could support a BIG sohc habit. Think of the possibilities.

Terry in Australia · « **Reply #256 on:** February 16, 2016, 11:00:58 PM »

Looking good Rafi, I especially like your plating, it looks very professional! I don't know what sort of sewing machine your wife has, but if it's just your standard dressmaking machine designed to punch a small needle through soft materiel, you're gonna be disappointed.

A good upholstery machine will have a big motor and clutch/gearbox, works very slowly, and can punch a big needle and thread through several layers of thick material and pull it together tightly. I've long wanted an industrial sewing machine so I can do my own seat covers, but they're very expensive, and most used ones that have come from upholstery shops are pretty much worn out. Best of luck mate! Cheers, Terry.

Thanks DH and Terry! Plating is a long, boring and tedious process so I'm limiting it to only the NLA stuff. I plan on replacing everything else with stainless steel.

Regarding the seat, I did manage to renegotiate the price with MTZ based on me getting some additional work done, hopefully it will work out OK. The machine at home is meant to go only up to as thick as Denim or Corduroy so it can handle the relatively thin vinyl, but after trying out a test piece, I didn't like the finish so I didn't bother.

Way to go Rafi, I've seen so many good builds let down by sh1tty home made seats that I was worried that this build might go the same way. Good decision to stick with the pro's. I'll need to eventually zinc plate all the usual parts on my future K1 build, (picking the bike up in pieces today) did you use a Caswell kit to do your plating? Cheers, Terry.

Plating kit is all DIY. I keep in touch with my buddy Tom Gugliotta who wrote up the best DIY plating guide. After all the K2 bits were done, he and I had been chatting about getting the zinc to end up with a brighter finish. This build came along just in time, and I volunteered the parts I did as test dummys to his new recipe. It worked really well and was way cheaper than the kits. The only thing I used from Caswell is there final Clear/Blue passivation dip. Blue is very popular with folks here. The gold dip I DIY'd but was mostly only used on the K2 to keep the stock look. I didn't do the multi anode thingy (speeds up plating) or get a variable power supply (fine grain control). I just managed with one anode and a charger from an old router that had proper specs.

If anyone wants to try it, the DIY article is here. Tom will soon be updating it to switch out the Karo syrup with 2oz of clear vanillin (artificial vanilla flavoring available at grocery stores)

You took that seat quite a ways. It'll probably be a fairly comfortable yet supportive seat with the gel insert. Can't wait to see photos of the finished product.

Lets hope so! And here you go, what do you guys think? Personally, I think I could have done better if I had the proper tools (not bragging, just saying I'd have shown it more love).

It looks great, Rafi. More importantly, it should provide some support and cushion for your posterior.

+1, looks good mate. Thanks for posting that plating article too, I'll check it out. Cheers, Terry.

The primary cush drive is back from Ralph in Germany after getting new cush rubbers installed and being re-riveted. This was made possible by our very own Wobbly/Tom, I can't thank him enough. Need to take it to the machine shop and get the new SKFs pressed in (I already had the SKFs here, distributor is right down the street but the needle rollers are always special order from SKF).

Also the new G67HP-6 HD Primary Chains made it home, hopefully these will work out better than stock, but they are slightly behind the CCC HD chains in specs.

A second box with some stock rear shocks and a like new starter clutch gear made it home from Bill Benton's House of Honda Fun Land

You can tell from the pix that the one on the K3 has taken quite a beating. It may still be in spec but I don't like opening up engines after I'm done with them, hence the better one. The dynamo rotor is at JMR's and he noticed that the starter clutch housing that sits behind the rotor itself has taken quite a beating. Getting a newer one of that as well as the rollers, pins and springs, those are most likely shot.

Roadriders and Metzelers are here, will take them to the auto shop for installation, any tips on keeping the powder safe on the Lesters? I was thinking masking tape, but would love to hear some ideas.

edwardmorris · « **Reply #267 on:** February 29, 2016, 09:50:03 PM »

Got the tires mounted. It was real fun trying to get the damned tube to thread through and get the tire itself on without scratching up the nice PC. Used a whole bunch of masking tape and pulled it off without a single nick

Also, I may be giving the rear damper rebuild a try. Acquired a used set that has some pitting on the chrome above the preload adjusters but are good everywhere else. The damping action is shot on both, so I'm going to try and save them by drilling and tapping a hole as shown here

Rafi,

Nice job mounting those tires without scratching up the PC on the Lesters!

edwardmorris · « **Reply #271 on:** March 01, 2016, 09:09:38 PM »

Thanks guys, just gotta balance them now. Where do you get those stick on balance weights? My crimp styled ones for the spokes are no good for these

Long day, but I did make some time to rebuild a test dummy rear damper. Was able to drill a hole through and gunky crud, (much like what falls out the front fork lowers after years of neglect) came out. It could have been the oil burning at point of contact (drill heat) but it almost felt as if they had some sealed gas. Unlikely as the it would easily leak out from up top. Anyway, pumped the crap out of it, poured some light new oil to flush it out some more, cleaned it up and tapped it using M6x1.0, but the damned el-cheapo brand handle for the tap broke in two

Finished up using a vice grip plier set (the tap itself was fine) and test fit a small bolt. Looks like this will work, will get the good set blasted first, then drain it, get it coated, then add new oil and seal it up with a small bolt and copper crush washer.

Wheels look amazing.

evanphi · « **Reply #273 on:** March 02, 2016, 07:34:04 AM »

Any auto parts store should have them, Rafi. They are also used on car wheels.

edwardmorris · « **Reply #274 on:** March 02, 2016, 10:06:27 AM »

Thanks! I'll check it out later this week.

Anyone ever use this stuff before?

http://www.amazon.com/ATP-AT-205-Re-Seal-Stops-Bottle/dp/B000NVW1LM/ref=cm_cr_arp_d_product_top?ie=UTF8

Thinking about mixing this in with the rear damper oil to keep the top seal from leaking. It does list hydraulic systems as an application and is available locally.
