My Honda Tact

[Paul604]

After sorting out a flywheel issue I finally got it running. Going to test out my wideband o2 sensor tomorrow and see how that works out. What other honda's use the same body panels? I need new side pieces that start below the flat floor piece and run along the sides, My left side one is cracked and missing the first 8 inches of it. I'll post up some more pics and video soon.

Pic with the new seat installed. Friend of mine covered it in black with a carbon fiber style vinyl on top.

did the dio motor just bolt and wire up or did you have to do some mods to get it to work

[Paul604]

Bolted up, all wiring was the same.

Nice resto! I wonder what all the differences between the AF16 and AF24 might be?

[Paul604]

From what I was told, just the gearing is different but I'm not sure what gears are in it. That's next on the list after it's tuned and running perfectly.

Gearing may be different, sure. Be sure to check out that boost port cutout on the crankcase, though. The AF18's is considerably bigger than the 16's. (12x24mm vs 6x12mm, respectively) I suspect something similar applies to the AF24.

Isn't the crank shaft diameter different too?

[Paul604]

The boost port was small in my af24, ported it out to match the cylinder i put on. Having some tuning issues right now, have a 50 pilot and been playing with different jets, smallest jet i have is a 85 that i had drilled out to a 110, and that is still too rich, had the 85 on there and it seem to run strong but too hot. Going to see if i can pick up a 105 or so tomorrow. Seems small for running a 51 cyl but i guess thats due to me only having a 19mm carb.

Which 19mm carb?

I recently spoke to an Actual Hawai'ian, who opined that compression for a daily rider should not exceed 120. That's sure been my experience with the Ruima 51 bore/Ministroker setup.

Glad you got your flywheel issue sorted. Thanks for the info on the boost port. Odd that they went back to s smaller case port. Wonder what other secrets lurk within the AF24?

[Paul604]

Keihin 19mm from jiangewayne. Did your engine cooling covers fit? Mine didn't. Had to cut them up to make them sorta fit. Wonder if that's my overheating issue. I've been checking heat/cyl temps with a ir gun since it overheated and stalled on me. Seems to hover around 300 right now. But I haven't been able to do any extended riding at all. Wanted to ride it to work today but my main is still to rich. Might go another clip down on the needle too since most my riding is mid throttle. Found a good spot for my wideband so I'll weld that in tomorow
and see what kinda readings I get.

Are you premixing? If your only using the oil injector then its not getting enogh oil.check that compression to.If its higher than 135psi and your using pump gas, that will add to the tunning problems and overheating.

[Paul604]

I will check compression again. Have to get a new gauge. I ditched the injection and have been premixing 32:1 with 94 octane.

The cover fit is a bit of a problem with both Ruima 51s I installed. I had to shave 1/8" off the outside ones and still have to ZipTie the cover halves to hold it together. Recommend muffler tape to seal any holes you created in the plastic. Also tape around the open area of the spark plug hole.

Spoke to a respected Hawai'ian today. He suggested compression below 120 for a daily rider. Any higher requires very close attention to jetting. You end up jetting so rich that you negate the power benefits of that high compression, and still risk overheating and cooking the bore.

I'm shooting for 115 on the 50mm kit for Flash 4.2. Flash III has been bulletproof over 1300 miles with lots of bad jetting choices. Maybe its 110 PSI is the reason? Still runs 60 MPH.

With the stock stroke 135psi would be the highest I would run .you should richen that oil mixture is a bit more.30to1 or 28to1.
