Don't you look at my accountant.
He's the only one I've got.

Fishie just emailed this through, sounds like the go for not much & Kapiti
- Start price: $50.00
No reserve
- Closes: Fri 18 Nov, 9:30 pm
- Listing #: 422355716
a not completed bucket motor project.
XL 185 motor with a xl125 crank in it to destroke it to fit inside the bucket F4 regulatiions
I built this from scratch and the new components are, mains, big end, rod, 0.25 piston, cam chain, cam chain tensioner and guide. valves have been lapped and head ported.
Have not installed the clutch but it is sitting in the box along with a pile of new gasket sets.
Pick up only please
Feel free to ask questions .

I could tell you Dave.I grew up in David Cres so it wouldn't be that anonymous. How do you know this stuff anyway?
But you never did the first pet bit.
Neils niche would have been extreme Euro boy on boy defecation & toy Fetish i guess.

Turns out, I'm going two stroke.
DT100 power for the win baby YEAH!

can you not find an 125 air cooled?
Oh well if the price was right. I will have a look for a RD Yam reed Valve and reed Rubber unless you have you got any. MY RD stuff is at the old mans but i think there is only plastic ones there though you really need alloy ones as they are ment to be better.
I have a map of the Porting for the GYT kit somewhere I think. no clymer
The mx100 had a closer ratio box from memory.yes it did
DT100A MX100
1 3.18 2.83
2 2.00 1.88
3 1.37 1.37
4 1.00 1.09
5 0.80 0.96
Turns out it is a clymer hot up but i will post it anyway it is old but a start. The MX100 has a 26mm carb vs the DT100 22mm
The thing with Yamaha's is better parts from the hotter models can be fitted, but more so for the 125cc bikes.

The price for the hundy was right, and although it will be slightly down on power it'll be better than the 125 pit bike motor by far.
Reed valves will definitely help, and a wee raise in the port timing and compression are very cheap ways to extract some more.
MVX expansion chamber might be a touch small, but it'll have to do. I think I'll use the high pipe so as not to limit ground clearance, which is probably the biggest hurdle to overcome when getting them to corner.
Crasher has offered to clean up the exhaust port too which is awesome! I'm not really giong for big power but more a useable motor, I really just want to know that it'll start every time and run smoothly.
Eyes that shine burning red
Very sensible.
Now where is the real Drew
gypsy
back in the day..(last century ) i used to have a DT100... that would fly... just ask GAV...
what a ride so far!!!!
Forum whore
Actually Drews engine is gavs old one !back in the day..(last century ) i used to have a DT100... that would fly... just ask GAV...
My neighbours diary says I have boundary issues

Just been looking at YZ100 pistons on ebay that would likely fit. 100 means you can run big carb, 28-32 should be fine.
Don't you look at my accountant.

I've never been about what bike I'm on mate, I more enjoy riding whatever I'm on WAAAAY past it's, and my own, limits.Very sensible.
Now where is the real Drew
I wonder if I could make it reverse ported by turning the barrel around, it'd certainly make the pipe easier to build!
No8 Wire Extraordinaire
people have done that with old RDs, but usually the answer is no, bolts preclude that & the boost port/inlet area can get complex, but maybe not so bad on a DT hmm , yeah Yams usually have a plain floor. then you don't want the carb picking up the front tyre's cast offs.
Don't you look at my accountant.

I don't plan on leaving the carb mouth completely exposed, but I suppose it'd be a mongrel in the wet.
Righto, lets work on the theory that the good people at Yamaha knew what they were doing when they aborted the reverse port TZR. Yet, the TZ was a screaming success and they had backward shit going on.
Ta
I just did a little searching, and sure enough, I can spin the head and barrel round and it'll bolt straight on.
So just for the fuck of it, I'm gonna run it that way so I can say I have a reverse port Yamaha that goes!

well you turn the inlet which is a big gaping hole on a yam into the thrust face. not an issue on a full case engine like the TZ or TZR.
Either way you are doing quite a bit of engineering to avoid cutting & rotating a pipe about 7 times to make a header.
