ESE's works engine tuner

[F5 Dave]

I rode a mates recently and it was a hoot. Even managed up this crazy 1st gear uphill goat track ok. On the dyno it looked like the pic posted. Sweet.
Perhaps you have a Stuck pv?

My Dutch friend has sent me his spare cylinder and a few bits and bobs to go with it, his good one makes 17bhp so I am keen on measuring things up against what I have. There are a couple of exhaust spacers which I have not looked at doing on my pipe so that is something else that could be of interest. Might be of some interest to you and Fast Fred, Tee Zee?
I put some pictures on the 50 thread

Look forward to seeing it all, maybe run it up on the dyno when its all ready.



Put the new Suzuki GP125 powered Bucket up on the dyno tonight. The dyno is great for cranking the bike over to check things out. But no joy, some sort of electrical issue. Kept blowing the 0.5A ECU fuse. After a bit of a look the finger of suspicion points to a bad injector coil, no biggy. The engine would fire up on "Start You Bastard" engine starter so the ignition is all Ok and the injector pulse width at cranking speed looked good, all in all things are encouraging. Maybe tomorrow night I will get the electrical fault sorted and an initial run.

will be intresting how the newer rs125 chamber go's

Otherwise known as `brake cleaner` in this parish. Started an 11yr layup gsxr in the weekend with a squirt or two of wynns.

More satisfying to shout Start You Bastard Start You Bastard than Break Cleaner Break Cleaner...........

Rob give us a run down on the bike and chassis as it now is on Mr Bigglesworth.

It appears to have a lot less steel than the old Yamaha based set up.
I note the number of Honda parts seems to be increasing.

...... Love that Mr.Bigglesworth.

Basically a Honda with an air cooled Suzuki GP125 engine in it.

MC18 frame. (yours from CHCH)
RS250 front forks.
RS125 rear shock.
2 of RS250 3.5x17 magnesium front wheel for the rear. Quick change slick and wet.
2 of Honda 2.5x17 front wheel. Unsure of the model. Quick change slick and wet.
RS125 style seat made in a heavier gauge of fiberglass to withstand push starts and crashing.
RS125 style tank (copy).
Honda RS 125 pipe.
Ecotrons EFI system.
Special 24mm ball valve type inlet system.
Dry sump gearbox.
Lots of extra copper fins for cooling.
Copper combustion chamber. 1.5mm of copper metal sprayed onto an original but modified Suzuki head.
Long RD400 Rod 115mm between centers.
RGV250 bigend bearing.
Clutch modified for an extra friction plate (originally six now seven friction plates)
Engine angled down so a cooling blast of air can be ducted to the center of the head.
Weight, as yet unknown.

Still struggling with a mystery electrical problem. The bike can sit there for as long as you like with the battery powered electrics switched on but shortly after I begin turning it over to start it, it blows a fuse. Isolated the issue to the ECU side, eliminated the injectors and injector wiring so what is left? maybe the unused O2 sensor heater wiring that was cut back. Everything was running fine when I took it out of the Beast for transplant into Mr.Bigglesworth????

Anyway with a bit of patience I will find it.

If its the single disk front wheel in 2.5X17 its likely from a CBR250R MC19.
Doesn't it have a pretty flash rear disk set up as well as a 6 speed and a Fletner one off Spacer, plus a biggerererer disk valve as well.

No this is the original air cooled motor resurrected to finish proving the EFI and dry sump ideas. The Flettner case and cylinder spacers are for the six speed 110cc water cooled version which may or may not have EFI depending on how things go when I finally get this sucker running.

I haven't noticed from any pics but are the bottom of the transfers in the crancase more gently curving with the wider bottom end of the LC6SP110 engine.

Also what's the new model weigh in at, compared to the former Yamaha chassis'ed Beast

[MotleyCrue]

Anybody know if the Ryger engine is something that is still promised to come about, or is it a dead deal, or still an unknown ?

[cotswold]

Thanks to TZ and Fast Fred for the help on the Dyno, we got the 50 running last night with the new insert head and it made more power but something odd happened to the rev range, previously it revved to around 14000, if we can get those back it should be pretty quick

That's a BMEP of 13.8 bar at rear wheel or pushing 15 bar at crank, at 9400 revs/min. That's some going for such low revs.
