Video Not Working? Fix It Now

I HAVE FIXED THIS ISSUE PLEASE CHECK MY OTHER VIDS!! Had to JET DOWN!!

Thanks for watching!! Hope this helps someone!!

Engine
- E3.36 spark plug gap .035
- Compression @ 150psi

Valves and timing
- Intake clearance was set very tight. I couldnt fit a .0015 feeler in. Set to .011
- Exhaust side is at .006. Not making excessive noise. Need to remove the valve cover to set the lash since I dont have a tool to get at it
from the inspection port. Would
also like to inspect the cam and figure out if its aftermarket.
- Possible different springs were used, they are blue in color..
- Timing at TDC seems as if the cam sprocket is a bit advanced. Will check again when cover is off

Carburetors/Air intake
- Sprayed starting fluid to check for leaks (none).
- Benched the carb and checked bowl height and set to .15 mm
- Cut 45 degree angle on float stops
- Pressure tested needle valve/seat, good.
- Jetting
- Mains = Left: DJ 155 Right: DJ 160 Starter = 95 Throttle = 80
- Needle clip moved to 2 from 5 -suspected rich condition after inspecting spark plug
- Found needle washer and spacer arrangement incorrect on both sides (missing washers replaced and arrangement corrected per the
manual)
- Set Left I/A pilot 3 out
- Set Right I/A pilot 2 out
- Conducted clear tube test both sides measure approx 3mm above bowl line and are even
- Snorkel deleted
- Checked K&N for proper seating

Electrical
- Found faulty reverse sensor connector and rerouted to ground
- Tested parking brake switch
- Checked plugs on CDI for proper seating
- Parking brake mechanism has been deleted and appears to be missing a switch, if so need to find
where the wiring..
