I wonder if that's the Dave Miller Concepts guy?....what's the screw on the bottom R/H side of the barrell?.....the barrel does look funny to me, as maybe not a genuine YZ360 barrel?. Must have been built for flat track maybe with a gearchange spline on both sides. Tis rare to find and tempting.
-
I thought it looked odd.....I'm pretty sure the barrel and head are RT2MX items which puts a big question mark on his 3K asking price. Woody Kyle is a noted flat track engine builder and team owner. I think the seller is Metro clothing's Don Miller. Here's a YZ360 motor

YA beat me to it Firko, the bottom end maybe YZ ,not the top half .
-
I'm no expert, but I kept looking at the cylinder and head also. I would think the cylinder and head account for more than 1%. (are those cracks in the fins?) Still it would look nice in my RT2MX/YZ.
;D
-
Here's an RT2MX motor.....identical 8 fins to the engine for sale. The YZ has 9 fins plus the expansion cut outs.

Don't look like a YZ Ignition either, that another 1% ;)

Looks like this is the worlds most expensive RT2MX motor. Some folks haven't a clue eh?
-
Here's some shots I took this morning. The first two are of the RT2MX barrel intended for my Hindall and the bottom photo is the RT2MX motor in my flat tracker. As you can see, they're identical to the cylinder on the eBay motor that's claiming to be a YZ360-A.

Ironically the same guy is selling a nice Champion framed "RT1MX" but a close up of the motor shows that it's a reed cylinder.........the only thing is, they didn't make a reed valve RT1MX ::). He's either truly ignorant to what he's got or he thinks we are. ;D

hahaha - that barrel on the Champion looks suspiciously like the YZ360 barrel in your earlier photo Firko.. 9 fins and all..
Let's see, he's put the RT1MX barrel on the YZ360 bottom end, and the YZ360 barrel on the RT1MX bottom end..
Doesn't fill me with confidence in the rest of his mechanical skills... :o
-
I've got a sneaking feeling that you're right Tony. The engine in the Champion has the expansion cutaways as seen in the YZ360-A as well as having the finning extending to the reed block as on the YZ cylinder. The RT2 reed cylinder has neither the finned reed block or fin cutouts seen on the YZ cylinder. Would someone be so dumb as to mix up the top ends on their engines? Surely not ::) Something very odd here :D

YZ360 barrel

I thought swapping the cylinders between the RT-2MX and the YZ360a was impossible, due to rear stud spacing??? Are you sure that's not a RT3 barrel on the RT-1MX motor?
If it is possible that is a weird thing to forget about. ???
-
I give in, it's doing my head in :o
-
Firko,
I see the screw to block the oil line and I think I can make out the auto-decompression valve. The plot thickens; RT-2MX as YZ360A and DT-3 as RT-1MX. Hmmmmm
-
Guess with everyone focused on the RT top end, it may have slipped people's attention that the engine caters for right hand shift as well..........
Was this the norm for a 360A?
-
doing my head in 'too', i'll continue reading. First look shows [RT2mx top end for sure] & off course T_Red hit on the crancases as YZ cylinder has wider spaced rear studs. Wonder if it has YZA/B straight cut primary clutch & crank gears swiss cheese selector drum--where do you stop [YZ crank wheels which are hollowed out with a band around them [sort of] & on & on. Not wanting to be 'too' picky--maybe he's not fully aware of the fine detail & was just told she's yz built from new parts, [which two parts--outer covers--obviously are]. Didn't think the clutch cover allowed for the DT1 shaft to extend through--maybe machined to take a seal etc, anyway, ummm--looks good!!.
-
Hey, is the sprocket nut on back to front? maybe not enough shaft thread to put on right way [ie sprocket only 'just' on splines, what's going on inside.
-
YZB's case have the casting to take a right foot'a, maybe some of Torsten Hallmans early imput

-
hmmm not sure but thought the clutch cover was cast 'not right through' but just to support the end of the short shaft. Have a cover in the shed but too cold out there tonight. Can't decide if there's a seal in the cover. Got everyone going anyway!!.
-
Only the very first few 250's had the right hand gear change that was not drilled through after a Cpl of months it was blanked off . non of the 360 's had right hand gear system to my knowledge . this could be done with 360 cases and a dt1 68\69 gear shaft . this looks like some of my left over parts creations .

YZA was designed to be able to shift either side, the frame on the YZA has some funny bracketry for the L/H brake pedal to be fitted. YZA outer cases where sandcast alloy and YZB magnesium. Definitely Hallman influence.

Just checked a f@#$& cold shed over here ,your right Morley the casting doesn't go right through on this 250B.

I just sat down to read these replies and found that I couldn't remember if my RT1 engine had the right change cases so I rushed out into my cold old shed and took the below shot. I've only got the short gear lever shaft in the engine but it definitely pokes through the cases so it's safe to say that early RT1's are drilled for right foot change.

And, a day later I took this shot of the rh gear change on my little red flat trackers RT1 motor.

hi guys the barrel and head are rt2 mx which means the cases are also as the yz 360 uses different rear stud spacings regards tony
-
I paid $200US for an outwardly crappy looking but internally perfect stock bore RT2MX engine, $100 for a YZ clutch cover and $300 for a Davy Crocket YZ clutch actuator which ads up to $600...a bucket load of money less than the 3k the seller is asking. Shit, I could buy a complete running and restored RT2MX for 3k ::).

KB171, not sure what i'm right about any more,-- I'll sit and watch. Cheers.
