After lots of searching the forums for information and ebay, scootertrader etc, to find the bike, i finally got my hands on my "perfect" et3! No compression, tired suspension and a paint job that only 30+ years on the road can give you. So, i have dutifully done my reseach (the dyno shoot out was great...and a parma very tempting!) and have put in my order list in, so thinking i should make sure i have got this right. This bike will be a daily driver, about 20-30 minutes each way and needs to be pretty reliable, quiet-ish, not too revvy, but still have some get up and go. It is replacing a tuned 210 so i can't just leave it standard... so here's how i've planned to run the bike for the first 12-18 months..... Polini 130 kit (will match the cases) 24mm Delortto (for a Rotary Valve, but not sure how hard it is to open the inlet up myself.....) Mazzucchelli Race crank 19mm (Rotary Valve) PK XL2 clutch reinforced with 4 plates ZIRRI Cruciform This will start life with the standard exhaust while it runs in, and will then move to which ever is quiter, a PM40 or JL Street Legal...unless there is a quiter pipe that will give me some revs whilst still having some bottom end. So with this in mind, should i be putting in a short 4th and/or and up gear kit? Also to make it go around corners, there will be bitubos front and back, but what tires do i go for? I used Dunlop TT92s on my PX so thinking the rear might even last more than 6 weeks on a smallframe! But what size? 90/90? Definitely looking forward to putting this together with the right bits, so any thoughts appreciated! Thinking 3 weeks and i'm on the road!!

Welcome, cracking little basis that. I'd be tempted not to touch it at all cosmetically.
My thoughts are to leave standard gearing, go with a standard cruciform and 3.50 x 10's. Not sure if the 92's come in that as not looked.
And when you say standard pipe what do you mean? I can't see the banana on there and if you mean the standard Primmy type it's not the best idea. I'd definately look at the PM40 over a JL, nice road pipes and probably considerable cheaper given the exchange rate.
I'm I right in thinking that's a PK rear hub?

Hi mate and welcome. Nice project scoot. I don't see the banana exhaust though (damn, Juan beat me to it ;D). The polini set up looks good, you could keep the standard primary, should be ok, or you could try a 27/69 straight cut with the possibility to swap the drive with different sizes. The short 4th shouldn't be necessary, unless you start messing around with port timings etc...

Pretty much what they said.
there's also the "halfway house" option of the rotary parma, bit cheaper than the other parmas. Not sure on performance but it should be better than a polini and is alloy barrelled as well which is good.

Really like the colour mate (anyone confirm that it's a non standard shade though ). I'd probably do the bearings and seals if the cases have never been touched, just for peace of mind. I use the pm40 pipe but for the price it might be worth considering the hammerzombie copy ash is selling. Better performance but more 'in ya face' styling... You might not need the XL2 clutch either, i've got a standard et3 with 4 plates and a malossi spring and it copes with 14 bhp fine. The one thing you haven't mentioned is the brakes, mine are total shite so I've bitten the bullet and am looking a disc options, not cheap but neither's my crash helmet Good luck on the 3 week turnaround too! ;D

Thanks for the input guys Re the pipe....well, looking at the photos now, i don't know if it's even got one! I was so happy that my mechanic found it that i didn't look underneath. It's one of his customers bikes and the owner didn't want to do an engine rebuid. He does have some sort of polini pipe kicking about so i will throw that on in the interim..... And am tempted by the uprated cruciform/clutches just as they have given me so much trouble in the past. Anything to save me pulling the engine apart to replace prematurely broken bits! Re the rims, I was unaware that 3.50s fitted without a kit of some sort. Can i just bolt them on? I have a few spare rims and a few TT92s/Conti twist races lying about so that would make life easier. Not sure on the hub being a PK, maybe easier to see in the photo below.... Given what's said about the gearing i will leave it alone. I can always change it if i do some more work on the porting in a few months. And yeah cracking colour. Really wanted a 70's looking paint job so this was perfect. I'll check to see if it's original and post the result. And sugarlump. I'd be interested to hear how you get 14hp out of a polini....maybe for phase 2 i keep the polini rather than getting a parma kit and just do more porting as it seems that these barrels give such a smooth fat power delivery (looking at the dyno shootout). And yes, the brakes.... i would like discs but also like the look of the original drums/wheels/fender.... I will replace all the internals and hopefully with "AntiAQUA" pads from SIP and teflon cables it will be good enough. Are there better drum options? I saw that some people race with drums!?! If not it will be discs in the future. So, thanks for all the input, making it a lot easier to make the decisions. OK, i'm back to work so i can afford all this!!

Hi mate, if you want to change the cruciform, use a DRT one, also use a strenghtened spring. Clutch wise, with a basic tune you'll be ok with a 4 plates. On my basic tuned malossi (sugarlump rans one too) I run a newfren 4 plates with malossi spring and its absolutely fine. For the brakes, if you don't want to fit a disc brake, you can use pk hubs and backplate. The rear one will fit on your engine, for the front one though, you'll need the pk forks. However, my Falc is a different story.

There's a PV back wheel on ebay at the mo'.
If you need an exhaust I think the one on my ETS is a standard PV one- you can have it for cheap if you're stuck.

SIP seem to have the biggest range of seats for small frames, so maybe try there. Cool scoot by the way

Hi Perkin, Thanks for the offer, i'll see what my mechanic has....he owes me a favour after blowing my speakers at his new years eve party! It ended up being a lucky break for me Hey Liseeloo, yeah i checked SIP but they don't seem to stock the seats Trevor who was at the dyno shoot out has one and the brand is Aquilla, but they seem to be an endangered species..... I'll speak with him again..... But I am only starting pulling the bike apart tomorrow so i have a little time before i will get to a seat stage.....and seems most of the parts guys in the UK are out of most smallframe bits, so i have a £600 box coming from SIP with polini, zirri, bitubo, etc parts. Going to be like a late christmas. ;D

Hi mate, for the seat, you can try ebay.it and if you need a translation, let me know.

Here is a similar one. Here is another one. They're a bit expensive though.

Ahhh nice one Max, that's more like it.
Shame it's white as i can't envisage me "pimping my ride" enough to pull that off....
Would anyone hazzard a guess as to costs to professionally recover a seat in black?
Any one got a sewing machine ;D

OK, engine out and in pieces. Looks OK in side but definitely needs some new bits. But one question. My mechanic was sent a "conversion" crank made by RMS so i can fit a PK flywheel. Not heard of one of these before and was just expecting a std rotary race 20/20mm maz crank instead. Is this really what i am after or was it a case of what was left on the shelf at the supplier! Hoping i don't have to muck about with parts but sounds like i wouldn't be the first..... So here is what i found when i got my hands dirty...more dirt! And some surface rust that will need some attention But all clean now! Apart from some burnt oil on the flywheel side of the case and old crank A bit dirsty on the inside... not sure it this is an issue if i'm replacing all the internals... but how much fun are steam washers!!

By conversion crank do you mean its 25/24 one? If it is, you'll need a conversion bearing to fit the larger crank to the et3 casings.

No, definitely 20/20mm, hence my confusion, not seen any mention of one of those before on any forums or shops. I had noticed that peple had issues with the 25/24mm cranks and oil leaks so kept clear......

is probably to convert from 19/20 to 20/20? ;D
