cutting out under WOT load

[tsears]

Hi,

I've fired my bike back up after a couple years of sitting (too busy with new job/career).

Bike runs great (really great!) except when going up a steep hill with throttle wide open. Then it cuts out a lot until I back off a the throttle a little.

Any ideas?

The bike is an '80 SG with 4:1 ex, individ. filters and Accel coils.

Thanks in advance,
Tim

I would says it's probably one of two things: insufficient fuel supply or a air intake problem. Perhaps a plug chop test is needed?

Main jets not big enough for 4-1 with cones?

I'd have to agree that is what it sounds like.

jets already way up there

Thanks for all the replies. This list has the most 'stand-up' members.

I have ordered a new set of mains - 145s. The bike has 142.5 mains and 45 pilots now. But the plugs still run very gray/white.

I'm also going to do a run with the cones off. BTW - the filters are K&N knockoffs - much cheaper in more ways than just price (i.e. construction).

Fuel taps probably need stripping and cleaning.
