well, just pulled the seal out.... lol! . i think i bought a couple these from a bike show. they have a metal outer case and not rubber like ive used before. maybe the all rubber type will fit tighter. I bought them thinking ide have less chance of knackering them up installing them.... Vale Honslows tomorrow 20mins away cheers cheers

Nigel,
Just had an email from Derek, he wants two but complete with CVT and, very generously, will give you till next year to deliver! Looks like you are going to be busy then? Do you need cash up front cos Derek`s got none now , could be a problem?

Dead right there John; Wunderbar!!

well it fired up ok tonight.... ran for 10 secs.... need to sort out some water to get round it before i let it go any longer. ill try and video it . thought i may have problems with ignition as the rotor doesnt  come flush with the coil part, but it started so ..... bounce bounce

i have got another project coming up soon Trevor..... as you know..., just waiting for the info to arrive lol!  Dereks doing ok , he doesnt need cvt , just slip the clutch more lol!

the cagiva barrel is bog standard which gaves 31bhp out the box, but a young fella told me yesterday that his engine was tuned to 42bhp same as whats achievable with the aprilia rs 125 road bike engine. so if i can get the engine and exhaust it to fit the frame , a run on a dyno will be interesting study

Many congratulations for getting the thing to run, albeit for a few seconds on the initial run, I know that a lot of hard work has gone into your venture, many would have given up much earlier, a great credit to you. However, I cant see a standard gearbox and clutch lasting too long with 30+ horse power going through it. Unless you know something we don`t ?

PostSubject: Frankenstein´s brother...   porous aluminium weld - Page 2 Icon_minitimeFri Aug 21, 2015 8:52 pm

I've got the wind up -- that picture I saw looked a bit more like Mary Shelley's laboratory for making a replica of Frankenstein than a motorcycle workshop -- and have a feeling Nigel will have a special rider, perhaps  looking like himself aboard doing fantastic body leans and late brakings ....

There was a pipe there with what looked like a thing from a dentist surgery where Nitrous Oxide can be metered into the patient´s lungs to have the poor soul laughing his head off whilst still feeling the pain.

And another thing about Nitrous Oxide -- when mixed with another gas and injected into the iintake makes sprint engies go much quicker -- for a short time only, of course.

Perhaps I´d better delete that last bit as being too much of a temptation...
Cheers!

The lawn needs mowing ...

Fantastic pipe and why two? -- noise and neighbours I suppose....

Well done Nigel!

Go well and stay well...

Yes, well done Nigel, a just reward for tenaciously pursuing your project and to get it running. Donuts and beer are on me when meet up again!
Nice pipe, completes a fine piece of creative engineering.

Pity about the dorks on KB, what do they know!!!!!

Regards Trevor.

been a lot of messing around,  as im looking to go with the cvt. so offset engine sprocket to keep chain in line for test only.

got the radiator fitted and associated pipes and auxiliary coolant pump off vauxhall insignia (25lt/min 12v) to circulate... the pump in / out water connections  turned out in a good position cheers

Nigel, very professional, impressive and a great credit to you, I hope we shall see it at the Avenue in November?

The Bathhurst pictures will be interesting and are very reminiscent of the early DKW set up with duplex, case and cylinder inlet, see if I an dig out a picture or two for comparison!

Cheers, Trevor

Glad i went with the water cooled crankcase... looks like i may have an extra plenum already... cheers cheers

porous aluminium weld - Page 2 Plenum10


i think probably second  phase transfer plenum... maybe needs shrinking a bit to 125cc may be less... but better use of space  than water cooling? and after all the issues i had getting it to seal has been beneficial... i wonder what’s the smallest reed valve you can get without having to knock one up yourself?

Nigel,
If you can fill that annular chamber with mixture do you think you can shift it all in .002s of transfer phase at 11,000 rpm, it`s a long way from the bottom of the radius to the combustion chamber, perhaps better to pump cool water through?

Terrific engineering though, marvellous stuff, love to see it at the Avenue!

Cheers, Trevor

had to ditch the ducati ignition as it was playing up, cobbled together an aprilia rs 125 system. as i had most of the bits. carb has standard jetting which is not to clever 1/4 throttle but once through that, revs out nicely/ noisily could be that the exhaust power valve is held open. i need to have the exhaust modified slightly to fit , but its such a nice pipe its going to kill me to cut and weld. the pipe is an arrows which the welding is beautiful, be surprised if i can find anybody to match the quality. im a bit worried about the the offset sprocket i put together, the weakest link as of now..

after taking bike up the road for a quick spin... it flew... then it stopped:(  ... my barrel base plate sprung a leak:scratch: ... should have loctite securing bolts Rolling Eyes  also my mk1 offset sprocket failed Rolling Eyes but almost ready for another run out lol!

Seasons greetings cheers

got a bit of time on my hands so started up bike....Mmmm... gearbox under pressure, pressure test again!!! after finally fixing recurring air leaks from between inner and outer crank cases by forming gap for a nitrile string type seal... ive knackerd up the oil seal on the clutch side crankcase... mainly probably because  i didn’t get the shaft chamferd when i had it reduced to use bantam sized main bearings. first time this has happend, maybe i was a bit heavy handed / no lubrication on seal when i pushed it all together again.

A little vaseline works wonders-- blokes in our room in the army school used it on their hair....

...how daft can you get.

Looks very good Nigel -- on ´the sink ????

Cheers!

Have a good and happy new year!

i thought i would paint it again.....jocolor  and put some stickers on it so it looks like a proper bike

i did try it up the road a couple of weeks back... scared me to death, it was a bit damp and the back came  round pale   not too bad on mx bike on mud, but im getting to old for that now on a road affraid
