stage6 pro sport mk2

[SMALL CC TEK]

Stage 6 has some quality control issues if they are letting them be sold like that . Hell you will lose a go bit of port timing it that is consistent all the way up . Get a shot of the ports from up top and bottom side of cylinder Just a nice clean up yield more power looking at that.. Wonder why they let them go like that HMMMM

[jeppetheswede]

Yes
I will try to take better pics but i have no good camera.
Lended mine to a freind and poff gone never going to se him or the camera again.
And they have issues but they look better than airsal,hebo and polini.

But i havent seen any other ones than the ones above either so i cant say that mutch in this subject.

And its going to be cleand up and ported a tiny bit. 188 to 190 exthaust duration.

Will take it bit by bit and try in between. Have a freind with a dyno.

"The swede with gasoline in the blood"
Hope its premix with castor bean oil!!

[jeppetheswede]

Yupp could be
But it is a song from a swedish punk band back in the late 70s.
Gasoline in the blood. "bensin i blodet" in swedish.
Its about and old guy and his moped and freedom of riding it.
So the old swede with gas in his wanes.

^^ sounds like your race bike is going to be a Hammer! Just get it all in tune and that thing should rip. Maybe a cylinder Head Temp gage for the race, being that it's an endurance race. A CHT gage will allow you to monitor the engine during the race.

[jeppetheswede]

Oh i fuond somthing.
Was sifting trough the parts and found an ignition system for the cpi race scoot.
An mvt ignition systen with the alternator function.
im using it must be better tahan stock stuff. How about coils for the scoot.
Have been reading and looking and most of the stuff tey sell is bogus.
And the real stuff you have to buy the hole chabang and thats gonna kill my 500 buck budget.

[aeroxbud]

Both of those crankshaft should be more than you need for this build.

[ryan_ott]

A used coil off of a MX single Honda, Kawasaki, Yamaha etc would be better then the new $8-12 coils.

[jeppetheswede]

Ok and thanks for the input.
Then the cranks will hold dont matter witch i use. But it will be the doppler its brand new.
Mx coil is this dirt bike ones you talk about?
And have anyboby any experience with mvt ignitions.
This one has the part nr EXT 123 its for the cpi keeway.

[ryan_ott]

The ext is just a stock replacement with fixed timing unless you have the digital CDI for it. Yes a dirt bike coil from a CDI machine should work fine. Msd 8232 is another option.

[jeppetheswede]

Arghh
Hope its without revlimiter atleast. digital cdi is there a box option too this one?
Where can ifind it or is it out of production like mutch of the other stuff for
these old air cooled ones.
Will search the net and look for it if i can find it. And do you know whats the difference or are
they all the same? The cdi box i have is the stock i think no fancy markings or so.
Is there a cdi where you can alter the curve of it or anything else?
The msd coil is very familiar too me. So ill use one of them.

Thanks a lot for the help
