Yeh Dave I made that schoolboy mistake, so easy to do in the excitement of getting it back together :lol: The thing is it still started, didn't miss, and ran as good as stock :eek: :lol::lol: Damn amazed me!

cams are swapped, front in the rear and visie versie.....just my guess, easy to do. It will kinda start but that's it

problems after a build a really hard to diagnose over the net. You've taken so much apart and put it all back together....the electrical, the fuel (carbs) and the motor itself. It could be just one thing or even a combination

but I'm guessing the cams :)

Hah, not only did I have my cams 180* out a few months back, I rode on them like that for about 4 hours, with no damage, lucky? probably

i think the jager didn't help when I was installing them.. eek:eek:

just take the rocker covers off and check em out. The rear cam has a groove in it behind where the sprocket

If the carbs are to lean it will/can cause the engine to not start. Try fatter jets and see if that helps any. Make sure your getting spark, fuel in the carb, and of course fuel to the engine. Check all the simple things first.

A weak battery will do it too. Mine would crank over fine, but apparently not fast enough. Put a jump start on it and it fire right up after the plugs dryed up.
