Either way you are doing quite a bit of engineering to avoid cutting & rotating a pipe about 7 times to make a header.

Oh yeah, hadn't thought about that. Just looked to see if it'd bolt on and figured it'd work.

I'd concentrate on a pipe and carb to start with.

The gains from putting a bigger carb on my MB engine were phenomenal. It did take Dave threatening to poo in it to get me motivated but it was well worth it. I'm sure we will have an internetless chinwag about it sometime soon.

I think your cliff hanger times can prove that.

I would focus on getting the thing moving forward. Something i have yet to achieve.

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!

think i .. (we all ) should pop around and stand and watch you work on it....

Hahaha I wondered when Drew said it was a DT100 if Yow Ling had saved himself some freight

If so Drew, the motor has already been ported and had a brand new Wiseco piston in it. It has no doubt been sitting for quite some time, so might pay to strip and replace main bearings etc. It had a 28mm flat slide on it when i had it.

While MX100A transmission details might be interesting wouldnt a MX transmission be illegal?

WHY?

The Yz80 and yz100 was the comp bike if the MX100 is a MX bike Yamaha wasn't really trying that hard. THey couldn't even be bothered to remove the autolube?
Yes I think it had no lights but so does the crf50

Because with that gearing it would be so fast when it passed other buckets the air would be sucked out of the other riders lungs causing him to black out, simple really !

Because the MX range was the prerunner to the YZ range.

No from this info the mx series seemed to follow beside the YZ range.

We could Argue but who cares. The MNZ doesn't.
Unless you put one it. Drew hasn't got a MX trans as far as i know.

PS argue with these fellas about the MX vs DT vs YZ they have the same argument as we do it seems.
