'05 Silverado, 24k miles.
had replaced plugs prior to my purchasing. Bike sat for 4 years. PO ran BG 44k through it.
ProPipe. When I purchased it had no baffle. Bike ran great, except it being VERY loud.
Bike has a lot of decel
Got a new baffle and it sounds great! But still have the popping.
Bike also has a K&N in the stock air box.
No other mods that I am aware of.
The fuel pump is still in use. I plan to go pumpless
and still have a lot of decel popping.
From the research and reading that I have done, it sounds like that the bike is running lean.
Pulled the plugs this morning and they are showing rich. A lot of black carbon.
I can not see any obvious cracks on the intake.
Can you see cracks while it is still mounted?
I would like to do the poorman's bak
I know that after doing that, I will need to re-jet, but with it running rich now, not sure which direction to go.
Any help from the masters of carbs, would be great.
