cylinder reed intake

[Andrew1289]

I've been learning/working with a engine builder recently.

I was just wondering, cylinder reed motor makes more low end power than case reed engine. What if you took a 62t case and cut the intake off and welded a plate onto it. Then either had a custom cylinder with a cylinder reed intake set up made or just cut into a stock 61x/aftermarket cylinder and welded a intake on there. This could make more bottom end? Does any of this hold water? Like those newer billet cases could have gone this route, but then I guess it wouldent be a bolt on part. You would need a whole custom engine.

A case reed engine is the only way to go!
Having a intake track in the side of the cylinder takes away too much transfer port volume= less HP and torque.

Figures, or it would have been done already. Thanks

You have to remember, low-end power is relative. What's the lowest RPM that you usually see out of your engine under normal use?

Agreed.

The last step in the billet Banshee case I made was to set it up with case reeds.

Unfortunately our government decided no more two stoke ATV's and most guys switched to 4 strokes.

Yep, run a big enough stroker crank and you will have all the low end power you can use.

The "trippy motor" on ebay is just like I was thinking about. Plus it even has the extra ports cut in.

OK, for it's time... it probably was a killer setup, but that was before 62T cases came on the market.

another data point is the last CR250 motor went case reed before the thumpers took over MX bikes. That last CR250 motor never got the press/credit but it's awesome. Showtime did get the very last two stroke holeshot with it against the thumpers.
