Sev

I bought mine from Redline

I forgot to mention that I originally just bought the cylinders and bolted them on. A year later I had him port, it gained on top with out loosing anything on the bottom.

Like some of the guys have already said, call Cameron at Redline. I had him port my Serval and I love it. Tyler seen the Dyno run back in Febuary, 85.6 hp. CPI's, 35mm carbs, Cameron's domes, 4.5 timing.

I'm running 4.5 degrees

Mine is a 7 bolt also and its a Mod Quad

Factory shock revalved and with a little stiffer spring that was actually set up for my old 3" swing arm

Yes it was about 3 hp peak gain with shearers but it did fall off just a bit on the bottom. The gain in the peak was not enough to make me run out and spend the $ on new pipes, however if I didn't already have CPI's and was looking for pipes I might go shearer. i just posted a pic in the gallery, Its Black and White.

It was 51.07 torque after porting

I will have to see what I can find.

It was 46.51 before Cameron ported, I can't remember for sure what the torque was after porting, I know it was in the 50's. It was done during the HQ dyno day at Redline, lots going on and forgot to get the sheet. I will call Cameron and have him dig that info up and get back to you.

That was my motor and it did dyno at 85.78 after porting (got to through that .78 in there) lol. the timing is set at 4.5 degrees with Cameron's cut domes. I love this set up for a fast dune play bike. Oh before the porting it dyno'd at 74.54. and yes this is on pump.

A quote I heard once, but very true, "Speed cost money, How fast do you want to go?"

Forgot to mention that I had Cameron at Redline touch up the porting, and I'm running 92 non-ethanol.

I've got a 4 mil Serval, 35 mm carbs, V-force II's, CPI's, 4.5 timing, Redline domes, 6" swing, 22-11-8 11 paddle haulers. I love it! Great dune play bike.

I have a 4 mil Serval with CPI's, 35 PWK's and love it!
