Boss Noss Raptor 700 beat me

[SnowBigDeal]

I wouldn't have expected a raptor on Noss to beat me up Sand Mountain, Little Sahara, UT. Elevation ~5,000 feet. I may be off on my jetting, does anyone have a recommendation for my jets? Or is it expected that a 700 raptor on Noss would beat me?

 

Here's my setup:

Trinity 420cc Big Bore

17cc Trinity Stave IV Head

Trinity Pro MX Port/Polish

CPI In-Frame Pipes

35mm Keihin PWK Carbs. 148 main jet, CEL Needle, Middle Clip

Stock Gearing

 

Here's the video:

 

I'm not really a fan of posting up when I get beat, but I don't like to get beat so I gotta figure out what to change.

your mx port isnt really helping you. a dune port will really make your bike rip!

[shanYE west]

send them cylinders out and have them reported.

[1996dragshee]

Yup.That's not surprising with that mx/trail port. Be lucky you got that far ahead of him out of the gate. As suggested send em out and get em reported

I don't know the elevation at Sand Mountain, but 17cc domes could be hurting you too.

For a 300ft race, probably ok...but that's a LONG run...and max RPM could be hurting with too much cranking compression....

Are you running race fuel with those 17cc domes at this elevation? -5000ft

[dajogejr]

5000 feet? Ok, disregard my comment about dome size...

reporting will really help you... however, dont be upset about getting beat by a 700. I had a pretty good worked 700 and it handed its share of 4 mil banshees a loss. There was an 812 raptor on nitrous with the best rider in colorado in my opinion (700 based engine) up here at walden that handed damn near every 10mil banshee its ass. They are no joke.

 

found a vid of that 812..

 

812 raptor on the far side, DSXR1000 on nitrous in the middle, and a nice 10mil shee closest... race was at 8500ft elevation

i would get someone else to port those cylinders

[dirtydownunder]

maybe stick a 15t on the front once youve had new porting done, your power should pull a 15t well.

do you no how big of a shot that 700 was running ?

[SnowBigDeal]

Thanks for the feedback so far. Looks like a new port job may be in line. Any comments from anyone about my jetting? I figure next time I'm out there I'll go down 1 step. It felt pretty strong at where I had it, but I think I may be able to go 1 step leaner.

 

Are you running race fuel with those 17cc domes at this elevation? -5000ft

 

I run a mix; 1/3 91 premium and 2/3 111 Race Fuel. Premixed at 40:1 with Klotz Super Techniplate.

He was running a 30hp shot of Noss.
