CURRENT????????????????

WTF???????

i did that about 20years ago when i first started down this sorry path...

Sorry but I was more referring to the large amount of fxr's, and now cbr's that some say are against the spirit of buckets for various reasons, cost mainly. To the piont where some place's have put them in there own class there are that many.

How many model specific classes were around twenty years ago? I was om dirt then so am not to sure, but am interested all the same.

3 in current workable existence as far as I know. Have all been pretty reliable, I won't comment on power but Jason's is pretty indicative of a good one (when its going properly, not misrepresented by my half arsed philandering).

I've got enough stuff to make another.
What is it worth to you???

Mine, Jimmys and ???
You can't count Kens it's a KV. A different (older) animal. Nice rig though.

What sort of power would you get from one of these? *EDIT: "could you get?" and also "is normal without too mcuh effort?"

I think u miss the point , with these engines you get no power without too much effort, they arent like assembling a wharhouse bmx bike, they even harder than that

I have 2 pipes. It makes 22rwhp with one and 25 with the other. I posted the dyno sheets on ESE's thread if you are interested.
Just so you know, to make one of these is a HUGE undertakeing and therefore not cheap. You could probably buy 2 average (ie not good enough to win a serious race) complete running buckets for the same $'s
Re. when F5Dave said 'when it is going properly' it pretty much sat for 10+ years and we tried to race it at the last GP with almost no prep. Before that it was totally reliable.

Wow. Thats pretty good power. I wouldn't think it was cheap. Will have a check of the dyno sheets

Pretty sure Peter's was the same, the one F5 had for a bit. They are lots of work for sure - welding cases, machining, cranks and rods, cutting and welding head and cylinder, water pump, radiator and plumbing, ignition. The Steadman's were onto a good thing and I still rate them as one of the best bucket engines possible. i've given two of them a good thrashing at the 2 hour races and they were awesome to ride. I'm guessing they make about 22-24hp after comparing them to my old MB in a race.

And B grade and sidecars. When I started bucketting (early 90's) there was about 6 sidecars at Mt Welli. The sidecar GP at Ohakea was always fun to watch 10+ machines.
