Posted: Sun Mar 20, 2005 3:01 pm
I get questions all the time about what are the vital non factory updates to get the most out of the Cannondale /ATK system. So I thought Id throw a list together of what I consider vital and nonvital updates . Feel free to add any info you have.
Vital updates
1 Rod bearing -
2 Decompression mechanism inspection, tightening
3 Oil dipstick removal -
4 Sump magnets/paper oil filter/ or stainless mesh filter with magnets, more magnets
5 Full engine teardown and correct reassembly
6 Replace swingarm pivot with solid or studded one
7 Waterless coolant and or aluminum cam cover
8 Locktite everywhere
9 FX400 flywheel bearing replaced with 03 style
10 Checking / replacing fuel lines
11 Checking for sticking cam buckets
12 Magnets in cyllinder head
13 Checking water pump impellar clearance on aluminum impellars especially.
14 Checking cam chain pivot guide for cracks at the base of the guide
15 Removal of WWE wrist pin and installing good ones. Maybe just toss the whole piston in garbage.
16 Checking JE pistons for cracks. just toss those as well.
17 Pressure test engine for leaks
18 Replacing stator wires with high temp ones and heat shielding
19 make sure crank end play is between .002 and .010
20 replace all solid lobe cams with older ones or have them nitrided
21 remove ecm relay to prevent stalling issues
22 Valve spring shimming and or new valves/springs tighter clearances,checking buckets for sticking. Even new valve springs need checking and shimming.
23 metal water pump impellar mandatory for machines with no cooling fan
Non vital
1 Flywheel hub inspection check for cracks
3 Shift shaft shims to compensate for thicker gasket
4 Engine cover noise supression
5 Wiring harness relay instalation
6 Metal water pump
7 Status lights
8 Headlight bulb reinforcement
9 Higher grade rear shock bolts
10 Reinforce welds and mount on plates in stock exhaust
11 Rubber padding between the engine and skid plate to prevent plate wear
List will grow as they come to mind or added to.
