oh well its still leaking. through the cases into the gearbox it seems. Seals seem ok now.
Took the day off to finish it, just needed the flywheel taper recut & a shanked nut made up. Sadly not done yet so I'll push on.

Well it runs. I'm happy with the new head mount, thanks Carl, I couldn't have turned up that nut thingy like that.
Didn't want to start but the RM80 & 125 are different & once mounted 180deg it fired up.
So its still largely a 16hp engine with a dollop of 19 added on. That'll do me for now, but I won't be worrying Rich etc. New pipe should really start to bring things into perspective. (That perspective might be elation or depression) oh yeah the cases need to be replaced, that should help the cause, I'm really only band-aiding a broken implementation from 16yrs ago.
Hey. I'll take that as Ready for Taupo. Woot!

Well it was ready. Just it didn't last.
A couple of extra neddies & I would have been able to keep up with Rick I think. In the prelim you'd just pull a little on both straights.
Well I’m a bit in a pickle what to do with the 100. obviously it needs new cases & I now have a couple, but they need some work as does the frame to fit them as the current cases have different mounts.
So it went sad at the GP. Was going ok but 2 laps in as I changed gear it started to struggle & it was clear something was rubbing, dragging or otherwise seizing together. I pulled the clutch, engine stopped & didn’t try letting it out.
When I got home I quickly popped the cover off to be met with some filings dropping out. OK as expected, we’ve had a collision. As I took the plate off the flywheel (internal RM design) had rubbed heavily with the stator plate & destroyed its magnets.
Hmm, the screws holding the stator adaptor plate a loose. Now here was a bit of a weakness of the design. I had countersunk them but missed slightly so had to move the counter sink over a tickle & adjust the plate so that the rotor didn’t rub as it was off centre a little in the original position.
Check crank by wobbling flywheel. Clunk clunk. Hmm, well in C3 bearings you do get some movement. This isn’t much. Is it too much? Hmm
So what happened first? Is the crank movement a red herring & all we are looking at is the screws weren’t done up as tight as they should have been?, or perhaps I should have just used flat bolts so they don’t tend to centralise the plate to a position I don’t want it to be?
Did the vibration just undo those bolts? Or was it the crank moving enough so the flywheel started shuddering against the stator undoing the bolts?
If I bang another flywheel on (after re-cutting the taper) - will the same thing happen?, bearing in mind that I will need a 3rd flywheel to test that theory if it does.
I might have to ponder a while. And look for another RM flywheel.

Do yourself a favor. Take it out the back and shoot it.

Look at this, few years stateside & he forgets how to spell in English.
Wanker. I'm still blaming you

Year 15 update Dave
Are you going to start from Scratch with new cases that don't leak.
I see there is a Crm50 engine that may be available?
I still would mind see how the inlet was blocked of in the STD cylinder and some decent pics of the engine.

Engine isn't apart, & besides this wasn't a full exposay thread, esp as I'm not particularly proud of some of the earlier work I'd
done & the interim stuff is just rushed.
Don't have any money currently for starting a different engine, though I have picked up some spare crank cases etc & made a horse trading deal with another racer to do some heavy engineering involving big steel plates & ally welding. Maybe over Christmas.
I've been cutting up a cracked set of cases for ideas & have gone to a smaller reedblock from some misc 6 petal Yam probably 1KT TZR (not sure, turned up in my spares & also an RZ350 I bought).
Inlet is easy to block, just cut an oval of ally & shape it so it fits in the inlet port bevelled so can't fall in if you get scared. The port is then formed from plasticine & Devcon covered.
Sketchy is making me some piston bushes for the YZ100 piston.

Here is some Yamaha reed stuff.

I really really like the MB50 that the Mad Swede done.
Plasticine that's ingenuous.
Did you not have any playdough
The IT175 had 6 petal the same reed cadge i believe as a TZ750. I got one here and a rubber I got for a dollar of TM.
Whats the big steel plates about?
My new build is Crankcase reed and also a Honda.
Did you talk to Choppa about the CRM50

IT175 I can't use, for me thats too competition, though the TZR will be more modern. Yam reuse lots of stuff so won';t be common. Plasticine is a bitch to get out, but it does come esp if warm. steel is for bolting ally cases to so you don't weld them together.

I've just put the YZ100 piston in last night. The head needs optomising, but it seriously did anyway, the profile is waay too tall so the spare head will have a heap lopped off it & an 11deg squish area shape, then I can piss around getting the com where I want it.
Maybe I'll throw a water jacket on, that way I can crank the com up a bit more. I have bought a cheapo $29 galley pump same as Sketchy has just run on his. I'll find a battery & switch for the mean time & look at building a temp controller later. Problem is anything you build has to be tough enough to cope with the vibration. I hate batteries too. Really need to get a charging system, but that has to wait for more money.
New Pipe is almost finished. That should net me some more gains at the RS pipe seems just too big for the 100, no real surprise there.

Pix of the $29 galley pump please
No8 Wire Extraordinaire
Hmm, can't see any by themselves, there were a few last week. But here is the same pump with a tap. When I went to the local marine shop they were obsolete stock but heaps on TM.
Like this, but without the tap.

So first thing you are going to say is can it handle the heat? Will it pump enough?, esp as those hose outlets look tiny.
Answer: apparently, clearly it isn't designed for it, but Sketchy has been running one on a head & it kept the water temp done to ~ 50deg with a rad /12 taped up & tiny hoses. Hey, worth a go.
This is clearly a better pump but, unlike auckland, I'm short of pingas atm

Low personal B.M.E.P.
I was browsing a mailer which came the other day - Mitre 10 ? - and saw a camp shower with a 12v pump for I think about $30
Immediately thought of another use for the pump.....more options than just Marine.
