Throwing this out there...

What’s the definition of plug and play when we’re talking about cylinder setups?

Straight swap?

Porting?

Just setup properly with timings? Port and ignition? And nothing else changed

Was wondering about some plug and play setups, but I thinks it’s never actually plug and play...

I would assume it means very minimal modifications. Straight swap and some gaskets to get the timing in the ballpark. I will also be doing minimal exhaust port shaping which is probably not pnp but not full blown tuning either. I feel its more PNP than not because it does not require a rebuild like case matching does. And that involves about the same amount of work chamfering does, which is required even for a pnp cylinder swap.

I suppose exhaust timings can be measured and setup without taking the crankcase apart...

But it’s still needs some attention to know how to set that up...

To me it means take the stock cylinder off and put the kit on.

Based on this, what do you guys think are the best kits out there now?

But the more plug and play the kit is the worse it will perform.

It’s also more fun to play and plug

Johny - That's an open ended question! It would be cool though to see a list of kits compared against each other and opinions, for each engine style. Something like this:

Engine - Maker - Kit - Whats in kit - Comments

For a PX200, the general consensus is that the Malossi Sport is the best choice for the money spent, but you'll always be tempted to go the extra mile and port & match the crankcase to the three ports of the Malossi (or Polini). To avoid this temptation (because it has the same [single] crankcase port as a stock PX200), the Pinasco 215/225 offers a decent boost of power, but it has it's critics.

My idea of P&P is not getting into crankcase or crankshaft mods, which both involve engine removal and splitting to do properly. With that in mind, there's always a mild 'O' tune of the stock PX200 top end rather than using a kit. Combine with a decent box exhaust and a bigger main jet in the stock carb.

Whichever one that can break a cruciform the fastest...

This thread has convinced me to install the malossi mk iii straight bolt on first without doing any port time adjustments to run in and get a benchmark to see how it compares to specifically setting port timing and exhaust port shaping at a later time.

I will take some measurements first to see what the port timings are at by default.

If you know how to measure the durations, then measure them. Just bolting a kit on plug and play is wasting at least one strip down. And is the reason the better kits give a selection of base gaskets to adjust to your individual engine.

Judging from some of the more challenging builds, I would refer to them more as “plug and pray”. 😀
