no fuel tp engine

[Loubob]

1986 gs450 L american model, with emmision controls

been sitting for 16 years,




Took the plugs out , primed cylinder, they fire right away and runs for a second or two. Cranking my throttle as well and still will not keep running. no fuel getting through




both bowls are full of fuel, have tried blowing on the fuel line still no fuel moving.



you would think one cylinder might be clogged not both
have not removed the carb's yet as the aircleaner on the american model looks like a real "B" to remove

any advice would be helpful, if you need more info let me know

thanks
Lou

The carbs need rebuilt..FULLY. After 16 years the passegs are clogged with god knows what...crusty old fuel, spider, various bugs crawling in there etc etc.

Heres the tutorial. Bet to Walmart and get a can of Berryman Crab and parts cleaner. Full 24 hrs in the sauce..disregard the labels saying 6 to 8 hrs. or youll be doing them again.

Save this place and cruise around all the links. See if your bikes manual is there. And here are some other links that will aid the rebuild.

This place has many CV carb parts. Be sure to back light the diaphrams and be sure of no pin holes in them. DO NOT grip the float seats with pliers to get them unstuck and no heat. Instead use a thin blade and get between the carb body and the brass edge and pry and work them out. Theres a oring inn there that needs replaced.

Here is the oring kit. 1 kit does all the carbs. Be sure to replace the orings in the carb holders as well. PATIENTLY work the phillips heads holding them on out and measure the ID of the oring groove to see what size you need. Replace the phillips heads with allen heads for future ease of remioval.

Adjust the valves and vacuum sync the carbs with gauges when yoiur done. You have to do all the maintenance and be sure its up to date to have an efficient and smooth running bike.
