Q about GILERA DNA

[tiba_karotsu]

today i tested a lot so with the original spring is a lof better on max speed 5-10km/h ! the start is slower but just a lit :] i can't expain my self why R.P.M. whit this spring are lower??? with 1.000rpm lower = more max speed so now i have to put middle spring to pull of max from eng.? or light rolls? and tomorow i will put the new carb

the reason is with the malossi purple spring you need heavier rollers to overcome the stiffer spring so when you switched to the softer stock spring the rollers you have on right now can easily overcome the stiffness & hence the belt travels much higher on the face of the vario.

if you are suffering from slow starts it is bcoz of weak clutch springs, too heavy rollers or both. try stiffer clutchsprings fist then lighter rollers next.

 

[tiba_karotsu]

tiba please give me some basic set up about the carb... it is dellorto PHBG 21 racing ds Main jet: 92, pilot jet: 50, needle W7 air screw 1,5 2,5 turns (basic)? needle possiton and air box?! new one or like mine now?

for best performance run it with a Polini airbox pod filter & then get a set of mainjets from 80 to 90 in these sizes (80 82 85 87 90), for the pilot jet get smaller sizes from 38 to 45 (38 40 42 45). needle position start with the 2nd groove from the top, air screw (i call it pilot screw) set at 1 turn out.

mhm i will try 5 gr. rollers? bcoz on max speed i rеach 10.000-10.500 rpm max! (in good weаther) on a straght or down hill it's the same... don't forget that i have malossi gears 14/48

mhm ok, i will order polini filter but for now with original air box 21 carb or 17.5 ... the same :| (it is runing with out cover of the air box just with sponge)bcoz there is a lack of air

at last some news,today i order polini evo 2 Cylinder whit crank evo and polini airbox now i am thinking for the exhaust bcoz now i am whith Gianelli Extra .... what can i expect whit it???? i know that it is for much lower RPMs,give me some offer for the best pipes for EVo 2 and best money-quality-max power pipes

Gianelli Extra isn't the best pipe for your kit, the MHR Team, Polini Evo or Roost custom pipes are your best choices.

:L

 

[tiba_karotsu]

good looking parts you got out of the box, have you decided what pipe to run?

 

[r3ar_vi3w]

no,but maybe MHR evo... i have whole winter in front of me
first port file + polish then carters .. geting SKF C4 bearings :!

 

[r3ar_vi3w]

problem.. i make phone call to skf and they tell me that bearibg whit 52x20x12 sizes is just standart for scooters they can't tell me is it c4 or c3 loose ... or its max rpms so now what?

 

[tiba_karotsu]

just buy the Polini Evo or Malossi crank bearings, they are C4 clearance.

 

[r3ar_vi3w]

winter winter time for tuning 8)

I am working on crankcases and smoothening of the port areas :!
the firs run will be with my Gianelli pipe then i will buy someone,next job will be racing ignition

 

[r3ar_vi3w]

some opinions about tecnigas NON-E now i just need to buy the best pipe for my tund evo

 

[tiba_karotsu]

whatever you do stay away from Technigas, either get a Malossi Team pipe, Polini Evo pipe or a Roost custom pipe.

 

[r3ar_vi3w]

:L do you like it?? DPR team today i run it for the first time everything seems good

 

[r3ar_vi3w]

Tiba please post some opinion or idea,someone can post too :

so far you are doing great, nice selection of parts, i think you will have a great running machine.

Hey tiba!

so far you are doing great, nice selection of parts, i think you will have a great running machine.

Don't forget you and I have to set this one up too yet. How are you?

Here is the most recent shot of my build... the crank is installed and I, being a rookie, already screwed up. I didn't ream out the crankcases as noted in the Polini cylinder instuctions. How much performance will this cost me you think? Beause if it is minimal, I don't want to redo it. Any thoughts?

 

[butch-182]

Matching the cases to the cylinder will always make a great performance gain as you are effectively removing a restricted area out, and making it "flow" instead of having a smaller area to squeeze through

I would suggest taking the crank out - if you are looking at doing this yourself take a look through the dutch section ( and English of course ) and see how to go about this.
You will not only notice a hp gain, but power curve will change and you will get a nice clean response of the bike too.

Nice parts - Just need to spend some time getting the cases matched to the cylinder now

Best of luck !

Thanks for the input.

What is a bummer though is that I know how it needs to be done, but don't have the $500.00 worth of tools needed.

No crank installation tool
No Reamer
No bearing puller

:'(

What's worse is I paid a shop $70.00 already to put it in.
