Re: Flash III Build Chronicles
What did you do/use to port the boost? I have always been concerned of scraps falling down into the crank.

Re: 95' Elite SA50 PS restrictions?
The CDI is not a limiting factor. In addition to your mentioned de-restrictions also de-restrict the airbox - take it apart and you will see where there should be 2 opening for air to go in but only one has been cut out.

I believe what you said is correct as far as the calculations go MK. Still not sure if that is a proven method but I wouldn't doubt it. I hope that it holds true because I wasn't looking forward to measuring TDC volume with a liquid. For simplicity, lets say that we had a 50cc engine with a TDC volu...

Re: The Breakfast of Champions
Also the thicker base will advance my exhaust timing and I'm guessing that might be a good thing. What do you think? I'll go measure what the timing is now, brb. I think it would be best to adjust the base gasket, as previously described, so that the piston is just low enough for the exhaust port t...

In my limited experience, I have never heard of calculating compression that way. Can anyone verify this method? I'm not denying it I am actually very interested in this. It seems to be accurate. It appears to account for decreased ring efficiency and give a more true compression, assuming you know ...

I had the same situation with my '97 SA50P. De-restricted the exhaust, airbox, put in a Keli pulley and swapped out the 68 SA50P jet for the 78 SA50 jet. I wired my oiler wide open and if I let it sit at idle for a while I will get some nice smoke coming out once I rev it up from the excess oil that...

Last year I broke the piece off of the casing where the motor mount attaches to the case. I believe it was off the left (larger) side. I had it welded back together and haven't had any problems thus far. DandyDan, if you decide to chop two different AF16 engines please let me know because I would be...

If it is a spree it does not have a variator. If it has a variator it is not a spree. They are mutually exclusive. The Spree has a fixed gear drive ratio. You can increase top speed, but it will come at the cost of bottom end acceleration. See the pulley mod discussion if interested: http://www.hond...

What model is this intake off of?
I'm confused as to what model this intake is off of. This is a SE engine. I want to run the oil pump but there is only 1 inlet on the intake and one on the carb. I know that the 94+ carbs have two inlet and an intake with only one inlet, but this is obviously not a 94+ intake. Everything I have seen...
