HI THERE OK, ZZR 1100D5 ALWAYS BEEN A BUGGER TO START FROM COLD EVERYTHING CHECKS OUT OR HAVE BOUGHT LOADS OF SPARE STUFF TO TEST, SET UP AT MOMENT, FULLY CHARGED CAR BATTERY POS CONNECTED TO STARTER STUB, NEG TO FRAME, SO ELECTRICAL SYSTEM IS BY PASSED, PLUGS ARE IN FOR THIS, TOUCH POS LEAD TO CAR BATTERY,CRANK IS ROTATED VIA STARTER IT TURNS 180 DEG AND PAUSES THEN ROTATES 180 AGAIN AND PAUSES, SO ON, AND SO ON, BUT BECAUSE THE CRANK ISNT ROTATING FAST ENOUGH THERE IS NO SPARK,IF YOU KEEP THIS UP IT EVENTUALLY SPEEDS ENOUGH TO CATCH A SPARK AND THE ENGINE FIRES UP BUT NOT WITHOUT A FIGHT, WITHOUT PLUGS AND NO LOAD FROM COMPRESSION ITS SLIGHTLY BETTER, BUT ONLY AFTER 5 SECONDS OF ROTATING THEN SPINS THE ENGINE, LIKE IT SHOULD DO, HAVE TRIED THIS WITH BOTH STARTER MOTORS AND GET THE SAME RESULT FROM BOTH. ?????????

The first thing I would do is replace the spark plugs again. You can foul a plug and it will cause you more problems than you can ever imagine. I see you have done all the logical things that I would recommend but I did not see you have replaced the plugs after the 200 miles. You would be surprised at how many times a $2.00 part can cause fits beyond belief.

Hi Jose ,
It seems the timming may not be correct thus the back-fire.
Please check the ignition timming and valve timming too .

Hope this helps

Guess I should post my answer as a solution so you can rate the solution. Clarifications can't be rated. Any results yet? The timing should be okay. Sitting for two years will not change it. Pull all the plugs and give a shot of WD40 into each cylinder while pushing the starter button. This will get some lubrication to the cylinder walls and piston rings. It will also help the rings to seal up. Now do the compression check. The readings should be within 10 psi of the top reading. If using aerostart, spray it into the air cleaner not the carbs. The air cleaner will greatly lessen the chances of a fire caused by an engine backfire. Always have a fire extinguisher on hand when messing with the carbs.

Bear in mind that some of the rings may be stuck in the piston grooves and will not be free to spring outward to seal against the cylinder wall. The WD40 may help here also. The worst case is that you will need to pull the head and cylinder to physically free the rings. Your pike is now 19 years old and the valves have probably never been worked on. Now would be the time to re-seat the valves. Depending on the condition of the cylinder, piston and rings, you may want to re-bore the cylinder and mount new piston and rings. At least run a cylinder hone through each cylinder.

I was going to just post this as a "clarification" but have sort of gotten into it now. All I ask is a "Helpfull" rating The "Thanks for trying" rating is a real bummer for a guy just trying to help. Get back to me.
Not sure what manual you have but compression is never checked at anything above idle. Crank and idle speed compression should be 140 to 160 psi.

i had the same problem on my 1983 venture. i replaced the original battery wire with a #6 copper battery cable, from the battery to the starter selanoid and then to the starter, never had a problem again.
