Edit: actually fuck it, if someone wants to build a 'rule bending' engine then do it. And if you can start winning races on it, perhaps then we can revisit the rules and get a legitimate opinion on what is and isn't legal. Until then who cares?
Why do you think it is acceptable for some one to race a "cheater" bike so long as they don't win? If they finish in front of you, you're ok with that?
they gotta finish in front of me first!
haha who am I kidding I haven't ever won a race. Good question tho. I'm not to sure to be honest. if it was a competition bearing/conrod then nope wouldn't mind, competition crank or barrel may be another matter.(but you could argue that the bearings/conrod are part of the crank)
But what I'm saying, I think, is that most people putting in the effort building a new engine have a reasonable respect for the rules and won't push them too far.
There are alot of variables and most are beyond my understanding. I think you made the right move Gav seeking clarification from professionals(MNZ), would be good to see if any response comes from it.
It's really fucking annoying being accused of cheating. To clarify - my big end pin is custom made by Heat Treatments. It has 20mm ends, a 22mm centre which is offset .75mm, and it is the same length as a standard MB100 pin. My MB100 crankshaft is modified to take the 1mm wider big end of the rod I selected out of the catalogue at Pete's. It may fit a competition engine but it wasn't listed as a rod for one. It was selected for it's dimensions in particular the 105mm centre-centre measurement. The big end bearing came with the rod as did the thrust washers. The little end is one I chose also for it's dimensions, it could fit any number of engines and was not listed as a replacement part for any particular engine. The piston is KT100, the little end pin is MB100 as are the circlips. The rings, and you have me here I think, are KT100. As they aren't one of the listed items that are "open" then I suppose I am cheating. Though, being allowed to use a piston but not the associated rings would seem to defeat the benefit of using the piston so typically I assume the intention of the rule would be to allow the matching rings to be used.
The problem is the intention of the rule and the way it has been interpreted by everybody until now and the exact wording which allows an alternative interpretation. If you are a bucket racer you know what the rules are. It may not be written perfectly but everybody knows what is meant and plays by the rules. Everybody I know and respect anyway.
My engine stroke is 1.5mm less than an MB100 due to the .75mm offset pin and has a 52.2mm bore. You can do the maths yourself. As if I'd build an engine and not know the capacity of it.
I agrea with you mike but
if the interpretation is "any part made for a compitition engine" then your crank is illegal
DONT LISSEN TO THE JACK ASS
it dosent say anywhere about parts made for competition engines
it dose say that the carb ingition and valves cam are open (so would mean that the rest isn't ?)
PS I thought that my spelling and england was bad but I can get most words in the right order

[Look guys I never sugested Speedro was cheated I simply pointed out By his own interation of the rules that he offered on the board both He and Dave were saying he was.QUOTE=speedpro;1130089144]This part of the rule clearly states that "parts" from "Motocross, Road Racing, Enduro and Go Kart motors" are not permitted.
this is my origional post that they both responded to It was never my intention to start a shit fight.
but when attacked I will respond
For the benefit of other I will clearly state my position
Whist the rules look like they have a typo they say what they say that's it warts and all.
They say what they say Don't shoot the messenger.
I would not race with a rs125 barrel or crank or gearbox because thats not what buckets are about it's a open sport that is meant to encourage devlopment at a reasonable cost for all.A class were a clever engineer or tuner can experement and show flair and parts bin raiding to get what you want but i would not feel guilty about using a cr125 big end bearing or a cr80 clutch Plates.
I to would want to see the s removed and the rest of the points cleared up.
I say we are all jackasses for being on the computer when we should be spending time on our bikes
Ps i do feel remorse for the coments mede about the shagging.But its was ment to be a slaging match thread wasn't it
While a little off topic , when I wanted to fit a RZ350 motor in my RD350 for pre82. I figured I was OK because the RZ350 had been shown at the Paris motor show in Oct 1982 (the cutoff is 31 dec 1982), fuck did I get the riot act read to me by guys in Auck who I never heard of, the "spirit of" catchall was trumpeted around and I gave up and put a LC engine in, the new rules now specifically exclude RZ350. Sometimes it just too hard to paddle upstream
My neighbours diary says I have boundary issues
so that mb100 isn't used in a compitition then ?
because if it is then it's a compitition engine F4 is a compitition with real races and such
Dave D can beat me by more then 35 points (no PC bull shit here)
the rules say the only parts you can use are pistons cams valves exaust and ignitions
