Buckets4me have you had a look under Dads bench lately? a bunch of GT125 engines have appeared there, and there is also a large offcut of 2mm copper sheet in the corner. What does all this mean????

I had noticed the nice new looking one on the bench last time I was there

Ahh C'mon it was a joke.

[QUOTE=speedpro;1129660904]The rules are pretty well spot on. TZ has proved it is possible for a 125 with a 24mm carb to make competitive power.

Has he?

Has he?

he proved that last year 18-21 hp at the rear wheel with a 24mm carb (proved that the carb is the restriction as he is getting 22+hp out of a 100 with a bigger carb)
now he is trying for lots more power (and he has 2 options)
just waiting for the dyno results to see how it's going (the seat of the pants say he is onto something)

thats reliable Hp to (1 bike has been going 4 years)
now how many other bikes are doing that ? ? ? 2 or 4 stroke

speedpro had a 100 that was good till it spat him off big time
??? any other bike out there (not many fxr's that old or reliable)
JC cb125 twins arn't as reliable (but have been around longer)

Hey Buckets4Me I was poking around at work looking for some flat bar and found hidden in a corner a couple of RG400 cylinders and an RGV cylinder that looks like it is being converted to air cooling. I think Dad is up to something he is not telling us about...

Picture-01 The plenum
Picture-02 Comparison of the new inlet tract with the an original
Picture-03 33mm straight shot into the crank case
Picture-04 New Delta rolling chassis

I have found a problem with running premix through my plenum. With a normal setup petrol/oil premix usually enters the motor wet and as the petrol evaporates the oil is left behind to lubricate things. But with my engine the wet fuel is evaporating in the plenum and leaving a lot of oil behind there and I wonder how much oil is actually making it into the engine.

So I have converted the motor back to a normal carb configuration, I had removed all the auto lube bits from the engine so I will now have to build a completely new one with auto lube. The up side is I have recently acquired a Delta and will fit the new engine to it. Chambers and I feel we have gone as far as we can with the GP frames and have been able to get ourselves two FZR250 Deltabox rolling chassis which we hope can be competitive handling wise with the FXR's.

The great thing about the Delta chassis is that its big enough to take almost any engine, 2-stroke single or twin, supercharged 4-stroke or even a Loncin or FXR if we get desperate.

They are considerably better handling wise than the FXR frame

Did you manage to get the bike on a dyno ?

Any idea what a "castec" frame from a honda spada would be like in comparison ? I don't know anything about the delta box..

Alexi and Chambers flat out fitting a GP125 engine to one of the FZR Rolling Chassis.

Std features with an FZR but not found on an RS chassis, you could upgrade if you want to.......

Miserable prick!
Surprised you didn't mention the hefty weight as well...
