Hi
Got a little question about the differences between the FJ and FL engines.
I have noticed the Dynojet do a different kits for each and the kit for the fl has larger jets.
So what if any are the Differences??
I was going to be getting a set of carbs from a FL but I'm unsure weather it's worth it or not seein as it might be setup wrong for my FJ engine.

Thanks Dave

 

Honda claimed the 89 and 90 model had 10hp more than the 87 and 88 models. Probably crankshaft hp not tire at the road hp.

 

Dave,


I think the question you are asking has to do with the technical differences. Honda did some porting and combustion chamber mods on the 89 model year. There also was a change to the ignition and carburetion. The carbs were increased in size from 32mm to 32.5mm. There may be a slight jetting difference. I'm not sure if the OD of the carbs changed I think only the throat was increased, so the larger carbs should fit on an 87. Tuning may be a little different depending on whether your motor is stock or not. I think you can get the later carbs to work on an earlier engine but you may need to jet them to your engine and performance needs.
