this is insane

Loved those pipes

where does the battery mount? do you have the bracket?

Awesome

Look great. Nice seat!

Cascade i believe did the dyno testing on the vf4s when they came out, made more power everywhere compared to the vf2s.

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.

Good point made above. Check the dyno section on when the servals came out and what they were making. I see no reason these cylinders will be making the same. Kind of surprised at the snipers though, thought they would be making more, the graph is pretty disappointing compared to the shearers. SLP tq graph is nuts compared to the other pipes. I wonder what the HP DL cylinders would look like with the same mods?

Keep us posted on that if you hear of the numbers. Heard that guys putting out some fast shit.' What other pipes are you trying out tomorrow?

Love the curve, and 50 tq is the most ive seen so far with these cylinders. For short track and trails these pipes are the shit. And these cylinders havent been out to long and every time i see a new dyno the hp is climbing. Wonder what other builders are working with these cylinders and what theyre getting for numbers?

Stand on the pegs and rock side to side to check upper and lower swing arm bearings, they can be a pain to change if there bad Pop off the seat check sub frame for wheelie damage Are tires straight, spindles bent? Take for a rip and go through the gears

And these guys http://www.jlengineering.org/mx-style-swing-arms.html

Sounds awesome!

Looks good, it should rip your arms off. How much extra HP did Driveline figure you will get with the mild porting over the cast porting?

Anyone know that brand of bumper?

I've used four vendors on this site and they've all been good but FAST has been the best.

Thanks CP!

...and are they worth a shit?

Buy the DRiveLine cylinders at 800 bucks, it's a no brainer. 421 as cast made 86 hp.

You got a great pile of quality parts. Looks like its going to turn out sweet, i like that colour you decided on.

Just curious as to how they will perform on a smaller engine after reading the specs on them. I have a 4 mil stock cylinder.

BUMP Who's running these under a 421cc engine? Has anyone tried them on a 4mil stock cylinder? How about a low port engine like serval or new DL? After 6 years of being out there are they the best I frame?

So who are the top pv builders?
