Hi Nile,

I have been thinking of removing most of the fan blades from the stater side fan as this is use to push air into the Cat exhaust. I would remove all but think the electrics may need some cooling on a street motor.

Since I no longer have a cat exhaust, I also plan to reroute the crankcase vent to the exhaust with a ck valve so that a vacuum is created therefore cause less resistance to piston travel on the intake and power stroke.


Thoughts

Thanks

Jim

nile, performance...
Someone familiar with the cooling flows of that fan will have to advise you on blade removal (be sure of everywhere that cooling airflow goes). Crankcase venting is usually connected to somewhere in the intake system, isn't it? Unless you've created a venturi type device, it would seem that the exhaust system would involve only pressure (which you do not want to hook to the crankcase).

Re: Nile, Performance question 1
Jim I don't get what you are talking about on the Stator? got pics? I know there are fins inside the flywheel!
just vent the crankcase up higher on the frame itself and put a uni filter on the end. I don't know if building up presure on the inside of the case would be a good thing.

High performance engine builders do this all the time. The hose from the crankcase is placed on the valve cover and then on the exhaust at an angle opposite of the flow and in a way the exhaust pulls a vacuum on the crank case.

The fan on the stater side is the pump that push air into the exhaust. I will get some photos etc. What I need is a longer rod for the 200!!

I have a couple ideas what a longer rod can do...

Hahaha

I am always getting junk emails for a "longer rod".

Actually some of them are kinda funny. The names they use are hilarious.

So do you end up higher compression?.......or lower...

2 things: Keeps the piston in the high pressure area longer (crank rotation)and it acts as a longer lever increasing the force from the piston.

2 motors with the same CI and Compression, the one with the longer rod will make more HP and Torque.

I will need a custom piston but that will bring even more to the table. Gas ports to seat the rings better, lighter weight etc

Re: Nile, Performance question 1
just deck the cylinder top. but you gota mess with the timing chain. I am working on a custom piston right now for my project. It's gota be tuff!

Won't do the same thing as the longer rod.

In addtion, I plan to up the compression to 12.5 / 13 to 1 add the malossi valves, cam, port the head, longer intake with exhaust to match total tune length and that larger carb, remove the compression release and try to reduce the rotating mass as much as possible.

I believe you would put a one way valve called a PCV valve on the line. The Vino125 owners says this helps a bit.

Hi Max,

Yes it is very similar. It is accutally a one way check valve made of metal to handle the heat. I am looking for a good artical to post about htis for Nile to review...
