The engine oil dipstick on my 550XP took a dump and the bottom 1/3 was missing. Apparently it's a common occurrence from the bit of reading I've done on it. Anyway I'm not gonna replace it just to have it happen again so I cut the rest of it off and ground it flat to use as a plug.
So now with no dipstick to check oil level I have some choices.
-Buy another dipstick to use as a dipstick...NOT
-Do an oil change and build a depth checker from the new full level
-ask the good people on QuadCrazy! Any one with a like year 550XP wanna measure their dipstick from the base to the end so I can make an oil level check stick?
I wanted to share an experience and a fix.
Headed out was following a pole line, was looking for a cross track that may take me to this speckle trout looking spot on a creek. All paths and semi paths... failed. Second objective was to reach a speckle trout lake that has been recently stocked... followed 1 trail to dead end, followed second trail to dead end.... while investigating options on foot and the quad idling it died.
It wouldn't start. eventually it did... and when it did … it was essentially a pinned idle. activating the throttle did seem to speed it up but it wouldn't knock out of the racing idle. couldn't put it in gear at that idle speed. got towed out.
when I first got the quad, I ran it off a trail and buried it pretty good in the soft snow... eventually winched out. It wouldn't start. eventually did and it was fast idling. not as fast as this last time. but still fast. it eventually seemed to settle and I got it in gear and by the time I was back to the truck was acting ok. chalked it up to the bike being at a bad angle in the snow.
My investigation last year lead to the throttle position sensor TPS. how to jumper the diag block to see the sensor position on the display,. I focused on this nearly sure it was a detuned sensor or broken sensor again this time.
I tore down the front plastic and stuck my head into the TPS area to see what I could see. What I found was that the throttle body assembly had actually come out of the mounting area (not sure what it is called). the ring clamp was loose I could move it easily. Hopeful, I tore down the air intake assembly above it (air filter...etc) removed a sensor clip and a hose.
I backed off the clamp some more and was able to reseat the throttle body assembly. put some blue lock tite on the clamp screw. When I was cleaning off the air intake assembly to ensure I dropped nothing down the intake, I noticed the underside of the air intake "box" also had a clamp. this screw was completely missing.
I went to the hardware store, bought a metric replacement (brought clamp with me), seated the assembly, settled the clamp blue lock tite that as well...
quad fired right up, idled normal, idled up without hesitation and dropped right back off. Cost of solution $3.87 CND for a pack of 5 metric screws. moral of my story was don't assume an idle issue is a throttle position sensor problem... there are a number of other factors including air pressure, which I believe was my issue.

FOR IMMEDIATE RELEASE
WPSA POWERSPORTS ATV TOUR ANNOUNCES RACING CLASS STRUCTURE;
SUPERSPORT SIDE BY SIDE HIGHLIGHTS ADDITIONAL CLASSES FOR 2007
WHITE BEAR LAKE, Minn. (Dec. 28, 2006) — The WPSA PowerSports ATV Tour will sanction 27 Pro, Pro Am, Youth and Amateur classes during the 2007 ATV racing season. Due to an overwhelmingly positive response, the Tour has added the Pro SuperSport “UTV” class to its Pro lineup, which also includes the popular SuperQuad Pro 450 MX and the Pro Stock QuadTerrain Challenge classes.
“When we ran the side-by-side vehicles at our last race of 2006, the excitement from our fans, our teams and our stakeholders was unmistakable, making it an obvious addition to our already thrilling Pro ATV racing show,” said PowerSports Entertainment, Inc. CEO Rick Murphy. “This, along with some important changes in our Pro-Am, Amateur and Youth classes, should make 2007 one of our most exciting seasons on record.”
In addition to the changes in the Pro classes, the Tour will provide alternative lines for riders wishing to run in the Amateur QuadTerrain Challenge classes, which includes Stock Lites (601-700cc), Stock Unlimited (601+cc), and Modified.
“We are dedicated to our ladder system in the PowerSports ATV Tour,” said Scott O’Malley, president of PowerSports Entertainment, Inc. “It’s important we allow Amateur riders, who have limited budgets and experience, a place to compete with an eye on stepping up to our top QuadTerrain Challenge Class. Alternative, amateur, lines will give these riders a place to compete without the concern of damaging equipment or racing at a level beyond their experience.”
The Tour has made several notable changes to its youth classes. Production Lites 13-15 will remain the same as in years past, while the 0-50cc Junior and Senior Classes have been modified. The 0-50cc Limited Class (4-6) will be open to quads with automatic clutch, and CVT belt drives, while the 0-55cc Production Class (6-8) will be open to quads with auto clutches.
The balance of the youth classes are: 51-70cc (production, auto clutch 6-11); 70cc (shifter, 6-11); 71-90cc, 2 Stroke, 75-125cc, 4 Stroke Production (8-11); 71-90cc, 2 Stroke, 75-125cc, 4 Stroke Production (12-15); 90cc Production (CVT belt drive, 8-15); 75-125cc 4 Stroke Production (8-15); 90cc 2 Stroke, 125cc 4 Stroke Modified (8-12); and 105cc 2 Stroke, 150cc 4 Stroke SuperMini (12-15).
The Tour has also split the women’s class into two classes: A and B/C.
The 2007 Rulebook, which is in the final stages of completion, will be distributed soon via www.PowerSportsTour.com.
