Cages, Floaters and Flyers / Found the problem
« on: March 11, 2020, 09:28:37 AM »
 :bang: been slowly rehabbing an old motor home for a couple of years now: brakes, tires, batteries, toilet, floor repair, fuel pump, new fluids and tune-up. I was going to drive it to work Monday to fill the propane tank, but it wouldn't start, just cranked and cranked.  :umm:
Last night, I discovered why:



It absolutely REEKS of stale gas, and there's a bit of water in that crap.



This rat bastard looks like it'll be way more fun to clean than a motorcycle carb, and then I get to clean out the fuel tanks!  :(

Turning Wrenches / Hey, RD400 guys...
« on: March 07, 2020, 01:53:34 AM »
My buddy has a 76 RD400 project he's building, and somewhere along the way he acquired a set of cylinders with, supposedly, Banshee sleeves installed.
1) is this possible, probable or maybe even common?
2) if so, why would it have been done?
He's got a set of stock cylinders as well, and we're talking about which set he should bolt up when the time comes. Thanks!

Events / 2020 One Moto Show, Portland OR
« on: February 09, 2020, 10:03:16 AM »
My son and I attended the One Moto Show and indoor flat track races yesterday at Veterans Memorial Coliseum in Portland, OR yesterday, and it was pretty great. Plenty to see and do, lots of cool bikes, good people-watching and good racing. Ran into some old friends I hadn't seen for 20 years and made some new ones. Had a conversation with a man who who knows a guy who knows Garret of GRA, and he invited me to ride with the Angry Bees. Saw one of Julian's bikes in person, finally, after reading about them for years.
I was happy to see our favorite kind of bikes pretty well represented, so in case you couldn't attend this year, I hope you enjoy my photographic attempts:

eBay/Craigslist watch / TZ250 parts (mine) on eBay

These are for H,J,K and some later TZs, not compatible (that I know of!) with RDs, RZs or LCs. I'd be happy to be proven wrong and happier still to sell this stuff. There's a list of part numbers on North American Two Strokes, Buy/Sell/Swap, 5F7 parts available.

Turning Wrenches / WSM pistons

Anybody have personal experience, strong opinions, general observations or sneaking suspicions regarding WSM pistons as sold by TDR?

Haus of Projects / Another LC/TZ Hybrid
« on: January 12, 2020, 02:45:04 PM »
I started this morning by harvesting some parts from one of the donors, including the front brake caliper I intend to use. Before I crack this thing apart, I'd like to know that I can source replacement parts...

Does anyone recognize this Brembo? I can tell you it was non-standard fitment on an '83 TZ250K.

Any recommendations for a replacement parts source?
Thanks, Wade

Haus of Projects / RD...what wheels?
« on: January 04, 2020, 05:36:32 PM »
I have a '75 RD350 that came to my doorstep needing a home, and I struggle with saying NO when it's an old friend (R.I.P. Dennis, I hope you're watching!) of my dad's and the price is $0. Typical story: all there but long out of use, with pistons which had become one with their cylinders, gummed-up carbs, rock-hard tires and a tank that looked lovely...on the outside.
In keeping with my policy of trying to use what I've got, I'm assessing options for wheels and suspension:

I read about Richard Pollack (sp?) of Mule Motorcycles using these Kawasaki wheels on his 'tracker customs because they're cheap and look like old Morris mags at a glance. Forks look like tree trunks, at least compared to the RD's...but the chrome is pitted, and it just got expensive. Also, the wheel is 19", so tire options limited, I'd have to BUY another wheel and brake and I'm not going in a 'tracker direction with this (as much as I like them).

'78 CB550K has a little wider front rim than the RD, but it's steel and also 19". Forks are a little beefier, but that leading-caliper look leaves me limp, and it's single-piston (I know, tech snob).

Matching Honda rear wheel is, I think, a tad wider than the RD item (but, again, steel) and 18". I'm just about talked into going drum instead of disc out back, and this has a nice, big old-school looking unit...but is it much different than:

this crusty old devil, to which I'd want to lace a wider, aluminum rim anyway? What else is around here  :umm:


Ladies and gentlemen, we have a winner here! 1983 TZ250 running gear has the much-preferred spokes with wide aluminum rims, disc brakes (Brembo calipers up front, I sold the rear caliper so will need something back there), an aluminum swingarm, stout forks with good chrome and a tasty set of triple clamps.

So, yes, I'm looking at a dual- to single shock conversion, no cush drive in the rear hub, no speedometer drive in the front hub, possible if not probable re-springing of the forks, steering head bearing challenges and I expect you fine folks will advise me what else.
Thoughts from the masses? I welcome your input, and reserve the right to charge headlong in a foolish direction heedless of thoughtful, logical and educated advice. Let's do this thing!

General Chatter / OW48R Wannabe
« on: January 02, 2020, 10:21:41 AM »
RC45 has posted some great pics of an RD500 project on North American Two Strokes under "two stroke projects". I highly recommend it and hope he'll put it on this site as well.

Turning Wrenches / On the importance of cush hubs
« on: December 22, 2019, 09:59:05 AM »
Today I want to know how important y'all believe a cushioned sprocket hub to be on a road-going motorcycle. I was reminded of this question by what I believe to be a KTM rear hub in that Motolana swingarm pictured in another thread.
Generally, street bikes have 'em and dirt bikes don't...but my TZ doesn't, and there are scores of dual-sports without them. I've asked a friend who has had plates on a couple of dirt bikes and he has had no problems.
To put a fine point on it, is there concern of long-term wear or damage to the transmission caused by use of a non-cushioned rear hub riding on pavement?

Turning Wrenches / Brake stay mounting point
« on: December 12, 2019, 09:19:01 AM »
What are the pros and cons of mounting a rear caliper stay arm to the swingarm vs to the frame?
