What's on your bench?

Fixed this 2016 Yamaha tw 200
It's been setting several years
Friend of mine bought it he was adopted out of Russia when he was little.
I call him Vlad the impaler because his wife has twins due in august.
Said wife let him buy it to ride to work but is now making him sell it.

Some head mods and port work on the Beta 300. Very minor port work, just a few "tweaks." Most of the work was in the head, I took .025" off the sealing surface just to get to an acceptable squish number (.048".) That meant that the head volume was going to be too small, so I then had to cut the chamber. Stock was 33cc, I'm at 31cc, so I'll still get a healthy compression boost.

Imagine a saw cylinder having this big of transfers. BIG quad transfers and a boost port on the intake side. Intake is case reed, so no intake port in the cylinder, leaves room for the boost port.

Efco 8300 The engine works, but it's a little crazy at idle, that's why there was no carburetor, although it's not his fault

Replacing sealants is inevitable / it is 20 or 25 years old

Don't forget the variable exhaust port height / timing.

Don't forget the variable exhaust port height / timing.

Yep, with the power valve in the closed position, it nearly halves the exhaust duration. On the euro bikes, the tension on the PV is adjustable via different rate springs and a preload adjuster as well.

Can Confirm.

Our 1993 1.3L cheap as to run grocery getter is the only vehicle I own that you can drive and not see the fuel gauge going down the thing runs on an oily rag and it's even got a good old carby lol.
Yeah it did the head gasket in on No1 as ya can see no carbon on that piston I got that all sorted skimmed did the valves and put in new water pump timing belt while I was at it.. shouldn't have to touch it for another 10 years.



Picked this old crusty up for $50 cleaned out the carby and she fired up good old 70's Suzuki's for ya... Not sure what to do with it yet I tracked down another complete one for $100 so I can build it back to its former glory if I get motivated.

Well, my primer & paint showed up today. Hopefully this Friday I can get this 562 case primed & painted.View attachment 362400View attachment 362401View attachment 362402

I’m not a very good painter, but this Summit Racing stuff turns out pretty nice.

Here is a Duke’s reserve 660 jug after cutting the squish band. The exhaust looks pretty good right out of the box.

Customers 394 im working on today, talk about cobbled together! Glue for the kill wire, and a modded 480 carb lol.

We took this in on trade a couple of months ago, it had an EFI Kohler with a plethora of issues. Went for the four bolt fix, upgraded from a 22.5 HP to 27 HP. Hey @Spike60 did you sell any TTX's when you were a dealer?

Got my home-fabbed log splitter mostly done today. I'm going to get some junk fire hose next time I'm at work and use it to secure/protect the hydraulic lines...also need to hook up the battery. I'll then figure out a table design for it after I get some time in actually using it.

Very nice. I think I would put some raised welds on the ram plate to keep the heel of the log from slipping.

Just finished putting this together for a friend of mine. I removed the baffle from the muffler and added a FW side outlet with a deflector. I used a Duke’s Reserve 660 cylinder which I think turned out pretty nice

Whats a Dukes "reserve" cylinder?

Don't cut the table.

I would call it a better-than-average AM 660 cylinder from Traverse Creek: https://www.sawsalvage.co/products/...s-stihl-066-ms660?_pos=1&_sid=bc8104a49&_ss=r

I wonder what the timing is like compared to the Cross performance one that mastermind helped design. I really like that Cross cylinder matched with an oem piston in my 660. I've officially got a season of sawing on it now, probably about 160 gallons through it. Checked it out yesterday, it's right at 180 psi with the base gasket, and the squish was about perfect at .025.
It would be nice to have a comparable replacement cylinder in the future since cross jugs are NLA

I should have written down the numbers it timed at before machine work. After cutting 0.040” from the squish, it was 99 on the exhaust and 84 on the intake. I didn’t look at the transfers before I raised them.
