Bike should be a ball to ride tho.

Now you really have me contemplating selling my stock cylinder/cpi set up for this set up.

What reeds did the vf2s replace?

 

85/51 is awesome final number, serval power at a way cheaper price. Nice bikd.

 

 i woul love to have seen a dyno on the hp cylinders wit the snipers, shearers, and cpi pipes.

 

This is Serval power on VP110.

Pump vs 110 on the same setup = 5-10 hp??

 

Same cylinder, same builder over the course of 5 years.

 

"As Cast" pump gas Serval = mid 70's whp.

"Clean-up Port" pump gas Serval = mid 80's whp.

And two race gas Servals that I assume are ported... mid 90's whp.

 

Here's a Dec 2011 Redline pump gas "as cast" vs "clean up port" Serval.

"As cast" mid 70's whp.

"Clean-up Port", no altered port timings, just shapes, angles and sizes, mid 80's whp.

Here's a May 2015 Redline pump gas "as cast" Serval, no clean up at all, mid 70's whp.

Here's a Oct 2014 Redline race gas Serval w/Shearer in-frames, mid 90's whp.

Here's a Apr 2016 Redline race gas Serval w/CPI in-frames, mid 90's whp.

"As Cast" pump gas vs "Clean-up Port" pump gas = ~12whp

"As Cast" pump gas vs "Ported" race gas = ~23whp

What does a 421 cub make HP tq wise on pump?

 

Aren't Cub's damn near drag ported "as cast".

I wouldn't run a Cub on pump if someone paid made to.

 

Here's the 4mil Cub pipe shoot out that Cam and Tyler did.

Passion Ported 4mil Cub on race gas made less on the same dyno than the two race gas Serval's from above.

Don't underestimate a cub on gas. I made quite a few Alcohol cubs look bad in Oklahoma.
