Sprintex?

Gosh OZziE, i was hoping some folks would get off on Ms Peel similar to me. Her Combat head got lost for a year so scored a standard small port head and upped CR some then experimented with a 2-1 long dong hollow megaphone till so disapointed I removed all the stupid Supertrap heavy discs and shot a 12 ga slug thru the soild end cap and moppingly headed out my driveway and gave her some normal throttle up to end up on rear rail of seat barely grabbing bars hard fast enough to stay her and catch the spin out, my shocked expression cracked into a disbelieving half grin, so reset myself for the rush and snapped the throttle to end up on rear of seat barely grabbing bars hard/fast enough not to be flat left behind!

About that time I got the 3rd front rod link on at a shop with its own MX trails bike course so took off with the hot to throt guys after job done, in disbelief of a heavy Brit Twin Roar amoung their ring-a-ding 2 smokes. Dropped 20-50 ft ravines so steep on climbs outs only way was to over power gravity on way down and stay on it on way up with head lamp pressing into my chest standing on pegs then the scary stuff blasting through head high brush in sheer glee like the movies of cars through corn fields. I tried one of their DR350's to feel like on pogo stick unstable beast, then got back on Peel and felt like freeway curiser over the wild stuff. Only hi centering stopped her so next time out both ends lifted 2" but air muscles can pull either end down 1" lower that factory so Ms Peel could also be classed as latino low rider dirt bike.

After that road racing handling on pavement in the tightest decreasing radii is refreshing relaxing predictable secure past time of solo riding after leaving the plastic coated parking lot cones behind but the 900's and above could out drag Peel after 90 mph but Peel could out zoom the 2004-5 600's especially in the mt climbs, so to put and end to that annoyance after the issue of the Ducati 1098, only blown big block dragster engine would keep up to at least 160 or so. Peel will definitely have more torque per lb than the angry looking insects.

My 1st Norton was dedicated wining P!! dragster on street rubber and I live on THE Gravel so cycling to me means loose as a goose is normal operation zone. I know Peel can handle the blower power but I'm pensive about me being a moth lead to the flame. Death is always lurking so trying to out run it while i can.

Btw Dianna Rigs was only women 007 ever married...

Cant see how these blokes who wernt broght up on the dirt have any developed sense of TRACTION at the edge , skipping hopping jumping biteing .
The old milking each ounce of grip via throttle & brakes to steady . Clay , ridges , drifts , potholes . We wont mention possums , cattle , deer :shock:
Milk tankers , cattle trucks , lunatics 4 wheel drifting 4WD orchard spreaders useing the whole road through blind bends on rainy sundays . . . .

I suppose the City Slikers get to pick which cars are driven by morons . we just assume they all are there . :shock:

Off road varies so much but if the tires aggressive enough and the terrain soft enough to get some bite then getting low on edges is doable in spades! The thing about loose or somewhat slick surfaces is getting a sense of bikes CoG behavior, how fast its wants to sling out on ya, how fast it will tip either way and the over controls that sort of crash ya back in line in time or just how much the bike itself self corrects. Its on the loose stuff I learned the hard way about reversed control transitions of steering into or away from desired direction w/o SPLAT! But nature is unpredictable so never fully in control like on pavement. There is ice and snow and mud and grass and sand and rock but only pavement and hard base Gravel paths behave the same as far as tires and suspension and power handling, as can not bite into surface only skip drift or slide.
You can qoute me on this - road racing is childs play compared to off road thrills to me.

Which brings us back to a positive or centrifugal blower off road behavior. I've had over powered craft and their can be touchy to stay in traction especially if turning, even a little bit let alone in bee line power. So far only events I've seen boosted bikes in are bee lines, sand drags, hill climbs and land speeds. Peel must first of all be a great dirt bike so don't know what the blower with drag only cam will be like. My hope is it will take throttle to climb a steep yet not increase hardly over idle rpm till just right point SNAP rear to a set rpm and hold till bike comes around then hooks up then smooth power on to stay in best slightly spun grip. One picture to hold in mind that needs some tire texture to do is zooming up a 'hill' side 30-40' steep on grassy clumps and nailing rear to swing up over head as front aims down hill to launch with gravity right back where ya came from. That maneuver puts a dirt bike on tire edges and forks to full lock w/o any power spin let off yet not so much it low sides - which it would but for the straight steering hi siding just enough. Maybe the 'soft' boost of the snail blower and the Powerarc ignition curve will allow it.

The other down low blower use is the parking lot stunts and gymkana parking lot cone events to whip it out on.
If system is controlable as I think it may, then one hwy stunt I want to master is hitting throttle and shorten forks at same time so the front floats level as Peel leaps forward so it appears as if Peel just lifted her skirt to float right out of there.
Closest land speed even is the Texas Mile. Ms Peel is crash cage triangulated now for public and off road use but will be removed for the so secure refreshing track days play.

Just wondering if any of you have had any experience with their superchargers?

Yes, but not with Nortons. If I'd be tempted to fit one on a Norton it would be an Ogura TX04 or TX07. I'd definetly use a Roots derivative like this "Wankel" as they deliver a linear output over rpm. The alternatives like the small centrifugal Rotrex s/c feature a progressive output and IMHO that makes no sense for Norton engine charactersitics. However I'd think that adding a s/c would also mean upping the whole drivetrain to make it cope with the torque increase.
