5k on a bucket? yer kidding?!?!! & what's more its a dirty diesel. yueek.
My '07 GasGas300 cost 5k And that's a lovely 2 stroke.
you should have known.
aircooled barrel & head carved to fit & on old cases for a trial fit.
Don't you look at my accountant.
He's the only one I've got.
Well that was interesting last night. I decided to dummy up the barrel on 1/2 a set of cases to see how shrouded the boostport was. It then became clear that I can't have done this 15 years ago as the answer is 'quite a bit'. But more so the whole inlet is quite shrouded when you put the barrel down. I will basically need to hack the back of the cylinder spigot off bar some retaining lugs.
Appears I was a bit stupid 15 years ago. Only continuing the trend by assuming I wasn't. Guess I was more focused on the issues to hand.
Inlet blocked off with some alluminium & devcon. Port being shaped & back of inlet to be glued on this week. Then I can assemble & do a leakdown test to see if the old cases are worth persevering with. (If I can then fix the localized oil leak). At least it staves off having to deal with the multiple water leaks too.

This thing is a bit like Chernobyl.
It needs to be encased in concrete for a few thousand years and you need to try and get on with your life as best you can in the circumstances.
That reminds me of one of the best websites of all time, its worth a look if you haven't seen it.

neato. so after a few nights adding a bit more devcon in layers so I can get the boost port through the old inlet I have a sealed barrel. Time to put it on the crankcases & do a leakdown test to see if these cases can be saved.
Out on the bench.
So after swapping the studs for std ones & fitting the barrel & head & a bung for the inlet manifold I screw in my gutted sparkplug with pressure gauge & give it a few pumps.
To feel air just gushing out & hitting me in the face. Hmm, bit of soapy water & ok its the reedvalve manifold. Quite a common place to leak I've found. So its not particularly flat. Again thanks Melmac's welding. Make up some gaskets & try get it as flat as I can. Now its leaking out a through screw in the manifold. I can block it up with a finger for the test. Pump some more in - still leaking but no where as bad. turn engine & spray some more suds.
POP! I shoot myself in the neck with the inlet bung. Thanks. To the lathe & turn a piece of rod with a groove so it will block up the inlet & clamp properly. Devcon the leaking break through. Try again tomorrow.
So now only two parts touching each other are the frame & front end.
I'm feeling this is still wasting time.
But my question Mike is: Do I need a basecourse before I start pouring & will ready mix do?

Well it is improved & I've traced some more leaks. Still the pressure gauge drops & it seems to be leaking into the gearbox. But not at a huge rate. I've devconed up another couple of areas. Its good enough to run. It will be losing some performance, but not an outstanding amount. I shall pencil in making some other cases.
So now the biggest bodge to hold me over till then. I've cleaned the cases at the back where they were leaking g.box oil when hot. I created a groove in the welded on rear section & have filled the groove with devcon. Actually I used JB weld for that. Next time these cases come apart it's to harvest them for the gearbox.
If I took a couple of days off & borrowed a pipe I may have it ready for the weekend. But that isn't going to happen. Besides the barrel needs a skim & a hone & ideally I need to do some preliminary ex port work.

Well after going home early from Kaitoke, my day has been useful. Spent several hours porting the air cooled barrel. Also knackered my compressor. Wipe away the 'maintenance' sticker. Hmm, daily; nope, never done that weekly: hmm, nope not that either. Monthly. Oil you say?
Quick oil change later, bit low but not empty or nuttin. Nah motor's fcked.
oh well, I've got a much bigger one that I've had since I moved in that I never commissioned.
So engine dry built & measured, to be skimmed & will be ready to run. Just need to machine the head & put bike back together & bodge on a pipe to see if it is oil tight.
Don't you look at my accountant.

Head machined & chamber reshaped a bit. OK for first cut.
Now just getting the old RS chamber to mate up with the MB barrel. The flange di is too wide so as a bodge I've decided to make the first bit of the header section tapered a bit more by cutting some avial slots & squeezing them together with a hose clamp & then welding them shut at the end. I've got a bit of tubing that takes it down to 34mm which is about right & adds a cm to the total length, but the last bike it was run on had a lower exh so it should run correct revs.
Got an old flange to weld to it & ground the pipes so at right angle (this will be an interim pipe to get things going). Then ran out of mig wire. oh well.
3 weeks till next race meet. 2 & 1/2 months till BOB.

Ahh yes. Hillarimouse.
Anyways a picture I bumped into just now of happier days whilst under it's own steam with the interim RGV125 aircooled engine at Taupo back in '07.
That's me 27 about to lap a Honda bucket & a young Av on the 150 in tow. Think the red bike is a Classic of some sort they mixed in with the bunch. A couple of them were ok quick.
At this stage I'd be happy if it went as well, at least for the time being.

Yeah I bent it taking it off so had to put it in the vice & give it a good hammering from many different angles.
You're a grubby bstd, I still can't see the name Fletcher without subconsciously converting it to 'Feltcher' (which used to be a common vocabulary inclusion in virtually any conversation with Jason or Chris).
