Hi guys :) :) I have questions about setup which i think to buy
Stage 6 Sport Pro Mk2
Stage 6 Pro – exhoust
Malossi Fly Clutch
Malossi Clutch Bell
21mm Stage 6 Black Edition (dellorto)
Motoforce sport crankshaft with c4 bearings
I take advices for parts from all :)
I have questions about crankshaft..Especially can i bough MotoForce Racing Crankshaft which is 90 euros or i need to take Motoforce Evolution crankshaft 100euro? first one is 10mm and the second have 10mm and 12mm what is difference between them? :)
Another question..Can i drive with stock airbox or i need to change it with sport air filter?? and Reeds too?
I want to say that i dont have a very big budget for expensive parts..
Thanks :)November 22, 2013 at 00:36 #3726
You should certainly invest in a tuning reedvalve and intake manifold! No need for expensive parts here tho. The Motorforce ones are just fine. The stock intake manifold is restricted to 12mm, so it wouldn’t help if you get a 21mm carb with the stock intake :)
About the gudgeon pin:
The gudgeon pin is the piece that holds the piston in place, on top of the con rod. A 12mm gudgeon pin is thicker than a 10mm one and therefore better for tuning use. It is not so much the gudgeon pin itself, but rather the con rod where its connected to. With a 12mm it just has more “meat” around it.

Thank you very much Daniel :) I think im ready about setup , but i dont have all the money yet.. Is there will be any serious problem if in start i drive with sport cylinder,exhaust,crankshaft,carb and intake parts only? without variator,clutch and …? i think there arent be any problem if i drive normally with these parts in start? after about 2-3 max months i will configurate other parts for good start,rev and others… :):)
Thank you againNovember 22, 2013 at 14:12 #3728
No, should not be a problem. But keep in mind that you will need to adjust the variator rollers at least. Tuning variators and stock variators use different rollers (and you willl need a different weight too with a tuning variator). So make sure to order a set of rollers for the stock variator.
If you want to you can also change the clutch springs of the original clutch but it’s also ok to keep it stock until you buy the racing clutch!November 22, 2013 at 18:10 #3729
Good,thanks! Can you tell me smth about airbox? what changes i have to make? i think with first setup (only carb,cylinder,crank and exhaust) to drive with stock airbox+stage6 or malossi double layer insert and later with all setup to buy malossi sport air filter? :)November 23, 2013 at 00:01 #3730
Yes, the Malossi layer inserts work well, but I would suggest to tune the airbox a bit. When tuning the airbox make sure that all the air is still filtered, reaching the carb. Simply increase the diameter of the existing airholes a bit and remove unnecessary parts.November 23, 2013 at 13:38 #3731
Okey:) Maybe i will try with Stage 6 Inlet Kit (intake manifold,reeds..) , Carb Stage 6 21mm Dellorto Black Edition and malossi layer:) and my question is how mm main jets i have to buy and test? With carb i think there is 92mm only .. And what more configurations i have to make about carb?November 23, 2013 at 19:09 #3732
I can’t decide which Jets kit to buy.. from 60+- do 80-90 or from 88 do 100+? i think 88+? And what you think about this configurations with Startly setup (no clutch,variator…only carb,cylinder,exhaust,crank) i think to put on stock clutch yellow clutch springs and big Yellow torque spring.. what is your opinion? i can’t decide to select rollers for stock variator too… This configurations are with stock clutch and variator.Later when i change them with sport i will change configuration parts:))))November 23, 2013 at 23:50 #3733
You should go with the 88 kit, yes!
Clutch setup looks ok too! Rollers will be about 3-5g I suppose. Main jet will be the most important adjustment. If it runs ok, I would stick with stock needle setup etc.December 1, 2013 at 18:29 #3735
Hi Daniel ! Next week im going to buy parts and finally i can’t decide what crankshaft to buy.. my friends told me to buy Motoforce Racing Crankshaft 90 euros (low midrace) for this setup becouse Crankshaft Motoforce Evolution(12mm) is for really normal midrace cylinders.. is it true or? i can’t understand this crankshafts.. can you tell me what will be difference between them? i know that evolution can handle 15,000 rpm … my cylinder never make this rpm .. i really don’t know please help me..
Thanks !December 6, 2013 at 20:09 #3736
Hi Daniel ,
What you think about Castrol 2T Racing (full synthetic) oil ? i drive now with it .. when i put parts i think to drive with it too .. What you think? And my other question is about how much km on low rpm i have to drive with this cylinder? Or i can put it to stay about 30 minutes in one place and it is ready ?

Castrol is very good! Also try the Motul 710 and 800. Both very good oils for high revving 2 stroke engines! Comes down to the price of the Castrol and the Motuls on which you choose!
About your crankshaft question: I can really recommend the BGM crankshaft. Not sure where you want to buy your crankshaft but check them out at Scooter-Center.com
I would go with a 12mm gudgeon pin crankshaft tho. It’s just safer for the future. You can also return back to 50cc stock and just use a 12mm gudgeon pin piston then. No problem!
