poor acceleration

Postby OkieVoss » Thu Jul 11, 2013 8:55 am



Ok here's what I have done. While checking for a fuel leak I decided to change the spark plugs since I had my bike torn apart. Well the plugs that came out of it were NGK DPR7EA-9 and I replaced them with NGK DPR8EA-9. Since then I have little to no acceleration from a idleing RPM, I either have to choke it a little or work the throttle to get it to accelerate. Now if I elevate the choke lever just a little it will accelerate great, it idles just fine and after getting up to highway speed does great also. Any suggestions. Oh set the plugs at 0.032 or close to it, anyway between 0.031 and 0.035. Also changed the oil, oil filter, air filter and fuel filter.

Trying to be gentle now...How did it run before you worked on it.?
Could you have pulled a vacuum line off?

There has to be more to the story, removing plastic to change plugs and air cleaner cant possibly cause what you describe.

Where did the fuel filter come from. Put the old filter back on and see if it makes a difference.

Take it back apart and look for something you broke, knocked off, disconnected or pinched. :?:

Well lets see now. I did wiggle some lines around but did crank and advance the throttle afterwards ie. before air filter change and after, but do not remember doing it right after the plug change, fuel filter that was on it was one that I had to search for and purchase from the local auto store but I did change it to a OEM Honda filter and it still does the same thing. It only acts up from a stop or trying to accelorate from a slow speed. I think I'm going to just take it to the local Honda dealer since I do not have the proper tools to even attempt this type of work, do appreciate the responses but I know when to tap out. Maybe it will not cost me an arm and leg.

What about putting the old plugs back in? It cant hurt if it was running okay before.

If they had been the places I've been, seen the things that I have seen, and done the things that I have done, then there should be no problem with working "... on stuff our age!!!"
