Gettin closer...

Nothing I like better than assembling a clean, newly machined and sealed engine.

SWEET!! It looks brand spanking new. Very cool.

I guess I missed a memo, what is this going into?

A good start?

 

[jestal]

Rad, that looks great....!!!!!! Did you use some sort of media blasting to get the cases and cylinder that clean and nice looking? Or you putting some sort of clear coat on it for protection?

Very clean and nice! Keep it coming.

 

[twowheelnut]

**** that! Where's the rims?!

By chance, did you take before shots? That be cool to see the comparison.

Glass bead, fresh medium (whiter) glass grit. No clear, just peel and get ruined by gas etc. Been there, done that.

The motor, only one I can find.

The front brake plate.

Rad, I looked at your original post to check out a picture of the bike when you bought it but the picture has disappeared. Can you repost it?

So, is Rad's Resto Restore officially open for business?

Nicely done Rad!

So, is Rad's Resto Restore officially open for business?Nicely done Rad!

Been open for some 25 years. Just never one this old, needing this much work. The pic shows a fairly decent bike, but the disassembly tells a different tale. TDubs post references some pms he and I did, where I stated I had about 80 hours into the wheels, that figure includes the brake and hub work shown above. Cleaning and buffing 72 spokes takes some time, as you can imagine. Rounding up rare, obsolete parts takes a lot of time and research. I have at least 12 hours researching, attempting to locate, then finally making 1 thrust washer for the transmission. Over $200 in stainless nuts, bolts, and washers. So far. If ya don't enjoy it, don't try it, it'll make ya nuts. But the finished product? Oh yeah...........

 

[twowheelnut]

Damn, that's gonna be a sweet ride! Thanks for the update.

 

[radman]

Oh, and it uses Amsoil Injector oil............

 

[charismaticmegafauna]

Hey -- didn't you hear? That's a no-no....

re -- T-20 Suzuki: Good (modern) 2-cycle oil often allows less pump throw adj. via 3rd throttle cable (read the plugs and look at exh. smoke). Suzuki used special (kinda') side-electrode spark plugs. Trans oil-level was initially set too low (using side case level plug) and the smaller two gears 5th & 6th (copper colored) tended to run too much out-of-the-lube. Suzuki issued a directive to 'up' the level a bit.

Nice looking bike, Rad -- one of my all-time faves.

Heard of that on the T500, case redesigned for newer ones, a trap made to retrofit the older ones, but hadn't heard of a T20 problem.

Well, it probably really only applied to bikes receiving lots of use -- probably not much of an issue these days (they won't get much use)? Those gears are relatively small and tend to be found fairly loose on well used engines.

Dailing-in the carb jetting really pays dividends, too. Being cognizant of your altitude and jetting accordingly. Stock was sea level. Burning out the muffler baffles (so they're clean) was part of the servicing regimen... (you probably know this stuff since you appear to be T-500 conversant)?

Congratulations, I hope it runs as good as it looks. A good 'seat-of-the-pants' dyno for the T-20 is carrying the front wheel just off the pavement on hard acceleration through 2nd & 3rd gears.

If the baffles were any cleaner, could use 'em for suppository insertion. Jetting is another matter, was planning on a 2 or 3 number bump just because Minnesota gas is 10% ethanol. Factory jetting tended to be on the rich side, as an obvious safety factor for them (warranty), so I'm gonna play it by ear I think. Gonna leave oil pump adjustment on the rich side till break in is over. Used GT380 piston/ring package, far superior to the original tractor slugs. Since it's gonna be mostly putt-putt on this thing, don't know if the wheelie dyno's in the cards, but one never knows.....

Rad,

You prolly don't hear this too often, lessin' it's on a canoe trip through West Virginia with Burt Reynolds, John Voit, and Ned Beatty, but that's PURDY!
