05 rappy 660 wont start.
This is going to be long. I have searched the forms for days and not come up with a solution.. I have a 05 660 bought It 5 years ago ran great...long story short I was climbing a hill (on the highway) going about 70 mph.. she overheated and the piston came apart. I know my motors and what not but this thing is going to be the death of me....tore it all down split the case to make sure nothing else was wrong. put it all back together with a 686 kit on it. I have all back into the bike...I have checked the timing, both on the crank and cam both line up, (has a little slop in chain when tensioner is out). I have been having issue with it starting...it cranks and crank and backfires through the carb but will not start, called dealer to ask if they knew and guy told me if it died at high speeds change the cam....so what do I do... put stage 1 hotcam into it..did timing an valves all over again double checked all of the timing marks and clearances spot on after 4 full revolutions by hand. try to start and same thing cranks and backfires through carb when given fuel. I have plenty of spark and new plug, but I did pull the plug and it was covered in fuel....so I'm flooding the motor I think...but what doesn't make sense is why will it not even try to start? I rebuild carbs 3 times, with 2 brand new rebuild kits. air fuel screws are set at 1 turn backed out. someone help please.
