Engine Bogs

Nutterhead · 06-01-2011, 08:22 AM

Hello All, I recently moved up from my GZ250 and my new bike is a 1986 Honda Shadow 500. The guy I bought it from just put after market pipes on the bike and it tends to bog down if you give it to much gas. I know this isn't a GZ question but you all have been really helpful in the past. He said the carbs just needed adjusted, is this true? If so can anyone walk me through how? I think I know I just don't want to mess anythng up. Thanks!

It sounds like you may get away with a idle mixture adjustment.I'm not sure where the screws are located on your model,but they should be in front of the float bowls.Adjust in or out,with engine at operating temperature to,get the smoothest idle.Worst case,you may need to install larger main jets,but I doubt it,unless they opened the air intake also.Nice looking bike by the way.I love the look of the older bikes.I had the same mirrors on my G.Z. Good luck!

This may sound like the dumbest question ever but I am still learning here. I found a small screw like thing by my carburetor is this what you are referring to? I imagine there is one on each carb and I should turn them both the same amount?

Yes,they should be about the same,Were ever the bike idles the best.If they are the proper screws,When you turn them in,the idle should start to be unever,turn them out slowly till the idle starts to roll,than about the middle of both extremes,where the idle is the smoothest.

:cool:

lol blain hopefully he isnt talking about his sync screws! anyway, its a single? if i were you i would open up the carb go two sizes up on mains, shim the needle hopefully there are slots on the needles if no your gonna have to find some washers and then up your pilot jet 1 size, set your mixture screw to 2 1/2 turns out. this is over the internet advice and i have no idea exactly what the bikes like but thats a bench mark bro

I didn't say you were doing anything wrong.She is on this forum,because she started with a G.Z. and upgraded to the bike she has now.She was asking for some advice,so she could do the repair on her own.I was trying to answer her question,without confusing her or any beginner.What you stated is true if you done mods to the intake,but are usually not needed with a change of exhaust.
