Re: Honda 115 to 130 Info

This question gets asked alot and the answer is almost always the same. While a Honda expert may be along shortly and can tell you in a heartbeat what needs to be changed, it is rarely cost effective to do this conversion and the results (if successful) will rarely result in much performance improvement. With four-stroke engines of the same displacement, camshafts, compression, ignition timing, exhaust and intake tuning, cylinder head and valve sizes, carb/fuel injections systems can all be involved. If you have a thick wallet, go for it. But in my opinion, your money would be better off left in your wallet or applied toward a new/newer engine of the size you really want or need. There are lots of less expensive things you can do to increase performance than trying to extract more power from an engine. Engine height, prop selection, weight distribution, trim tabs and jack plates are just a few.

Re: Honda 115 to 130 Info

Fozzy, I'am almost a 100% sure the only difference from the 115 to the 130 is the throttle body. I asked this question at a Honda training center years ago and that is what I was told. I've have only worked on a hand full of 115's, seems everyone goes to the 130, as they weigh the same. The one thing I did notice on the 115's when working on them is that the throttle plate does not open as far as the 130's. The difference seems to be the in the throttle opening and the TPS. The TPS is only available by ordering a throttle body assy. I do know that the complete cylinder head assy's are the same part number between the 115 and the 130. When we look up parts on our system you can click on the where used on any model tab and it lets you know if it is the same on both engines. Hope this helps out.....
