I won an auction on ebay. The item is related as a "stage 5" but Im not sure at all. Anyway, I´m just going to pay 20,5 euros for that cylinder, not a big amount of money

the exhaust port looks high and wide enough to be classed as a stage 5...................
but sadley.............the inlet and transfers seem to look a bit crap.........or should i say ...............a bit dissapointing..................

No . . . . cr@p was the correct description Sean. Although my first reaction was a ghastly crock of sh!tesean brady scooters wrote:the exhaust port looks high and wide enough to be classed as a stage 5...................

High revving without enough charge volume to make any real power.
Old skool the term "stage 5".... was the use of a Jap piston but with no major porting done to the transferes in the bore....

Correct me if I'm wrong, but I don't think theres any standards for "Stage" anyway- one mans stage 4 is anothers Stage 6, and vice versa.

Some info from http://www.mbdevelopments.co.uk/lambretta/lt2.html
WHAT SETS A STAGE TUNE?
Who says what a tune is? There are no rules only other peoples opinions and ideas, these have been around as long as two strokes have.
If there are no rules then what is a stage tune? Different tuners have different ideas. A motorcycle experts idea would be different to that of a scooter experts idea of a tune.
Motorcycle tuners tend to have three basic tunes, stage 1 road tune, stage 2 road/ race tune, and stage 3 full race spec tune, what work occurs between each tune can vary from engine to engine, or who you talk to or what book you have read. This seems to be where scooter tuners have shot straight to stage 4 road tunes. It doesn’t mean a stage 4-scooter tune is better or higher spec than a motor bike tune. Perhaps it suggests more stages of tuning to get to a similar spec of tune compared to a motorbikes engine tune!
Over the years I’ve seen scooter tuning getting to stage 8 and stage 9. This could be getting a ridiculous selling point! One opinion is when fitting a Japanese piston, a barrel suddenly becomes a stage 5. Why? You can fit a Japanese piston and still keep standard port timings, carb and exhaust with no extra speed! This doesn’t seem to be a stage of tune but presumably a stage of reliability. Are they both connected?
In the Fifties and Sixties stage 1 and stage 2 seemed to be used, by 1980 only stage 4 was used, by the mid 1980s stage 5 and stage 6 had crept in. Nothing was mentioned of stage 1, 2 or 3 where did they go? So much confusion. Customers have being asking for a tune they haven’t really wanted.
Let me try and put some sense to a scooter tune, but I must point out they are my ideas and may differ to other scooter dealers. There are so many ways to tune one cylinder I won’t go into much detail, that would turn this an article into a book. I base these on the amount of tunes done, listening to what the customer has required over the years and my own common sense.
LAMBRETTA CAST CYLINDERS
1. STAGE ONE. Basically clean up ports, keep standard carb and exhaust.
2. STAGE TWO. Clean up ports, raise exhaust port slightly to increase port timings, use either standard or slightly larger carb, Standard or Clubman exhausts.
3. STAGE THREE. Lower inlet port slightly to increase port timings, raise exhaust port, flow transfer feeds. Increase carb to 22 – 26mm, Standard, Clubman or a touring expansion chamber.
4. STAGE FOUR. Increase inlet size and port timings to match to 28 – 30mm carb, raise, widen and open exhaust port to larger big bore gasket. Flow transfer ports. Use a clubman or touring expansion chamber.
5. STAGE FIVE. Increase inlet size and port timings to match to larger carb 30 – 34mm, increase exhaust port size and port timings to slightly larger than a stage 4, use a full expansion chamber.
6. STAGE SIX. As above but perhaps larger port timings to increase power higher up in the rev range, also increase size of transfer passages. Use 32 – 36mm carbs and full race spec expansions. (Usually classed as a full race tune.)
7. STAGE SEVEN. As per stage 6 but with a reed valve fitted and the extra work needed.

THATS MY UNDERSTANDING AS WELL jap piston a pre requsite as old school pistons couldnt take the heat as it were now with more modern materials perhaps asso/meteor can cope with the expansion better who knowsJ1MS wrote:Old skool the term "stage 5".... was the use of a Jap piston but with no major porting done to the transferes in the bore....
We sleep soundly in our beds because rough men stand ready in the night to visit violence on those who would do us harm
I dont dissagree..... there really is no definitive answer now for a state of tune, as there are so many diferent types of barrels out there and so many competent tuners of barrels, all using diferent terms for similar states of tune.....but prior to all these new kits, the old fashioned tune was refered to as a stage four..... barrel, carb exhaust and head.....following on from this, Dave Webster in his day gave a referance to standard's of tune that till the mid to late 80's was sort of used as a bench mark for a state of tune.....I would put this down to his tuning book which was originally written into Norries monthly mag..... which in its day set the standards for the majority of up and comming scooter tuners......so when I say old skool I mean back in the mid to late 70's....but now its any ones guess.....one of my own barrels is a modified Rapido running on an Yamaha DT 175 piston with aditional boost porting running on a reed valve, I wouldnt refer to it as any stage of tune.....just kind of messed about with, sort of a TS1 Rapido 200....but not a stage 5 or stage 4.....Maybe MB now leads the way with tuning terminology as he now has alot of tuned barrels out there all given as a stage of tune.....
