Hi,
What are people running for ignition advance. i know on my banshee I have it set at 4 degrees advanced. How would this work on my rz350.

that's perfect! Just follow your banshee settings for +4. I wouldn't go further than that unless you ran more Octane over 100 I did so on both and the RZ's I own and the ones I've build. Works Great!. you'll notice alone the throttle response and if the jetting is a tad fat you'll see it clean that up down low.

Glad to hear that. Want to get it ready for the summer, now I just need to order one and get it installed. Guess I can put on the shaved flywheel as well. Bigger carbs and I am ready to go. I know it made a big difference on my shee. Was hoping for the same on my rz

it will. Don't waste the time and money on the fly wheel. Unless you weigh 110-140Ib it's not a good idea. On the banshee or the RZ. You need that extra rotating mass to keep the low end. We've stop doing fly wheel mods long ago sense we realized what it didn't help just hurt it. As well you'll notice the same problem when guy's use Button style fly wheel ignitions Example PVL's the bike sounds mean sitting there but it does take away power under a load. The Larger Carbs will benefit you as well. I just recommend if you do that make sure you at least have Pipes, Ported and compression. reeds will also be a gain. all this and carbs will fit the RZ Nicely. If not you'll be some what over carburetaing something that can't flow it. I'm also using a 33mm carbs and up for Example. If you plan on using 28 then you'll be fine with out any port work. Just trying to give you ideas to maintain the low end.

Yes just using 28 pwk`s. Already have a 2 into 1 intake setup, toomey pipes and boysend reeds, and head shaved .015. Going to do the advance. Think it will make for a nice little setup. Not the biggest or fastest, but will be a lot of fun.

Roger , would you say that + 4 degrees advance would be ok for my 421cc banshee ??? I'm waiting for the zeel to arrive.
What settings should I go for ??? whats your opinion as you have huge experience with these stroker engines.


Thanks

You'll have with it. Sounds like a nice set up.

Hi Petros! do you know what Compression you have on that Cub? Also what fuel octane? as well Pistons?

[cbn70]

not sure, might open up the engine and port the cases to match the cylinders. Have done this on banshees and works well. I have to put in a new set of rings so might just bite the bullet and pull the motor. The guy who started LRD performace in Oregon actually says porting the cases is good for 1-2 horsepower on an engine.

Roger ,

Engine has not fired up yet ...... , so do not know compresion ,
Fuel will be 100 octaine unleaded as going for a road bike ,
68mm Wiseco forged pistons.

How About Domes? what cc are they?

[KennyBarroz]

If i would get 0,9 in squish, would +4 in timing be good still?

It depends on what you want or are looking for.

Your still only going to be seeing about 15* at peak power, these engines if tuned correctly need a lot more than that.
Unleaded fuel needs to be run rich with loads of advance to get the heat into the pipe to make them work at the temp they where designed to run at.

There are so many things that can alter what ignition curve is best suited for a given tune, like the angle of the rear cone plays a major factor to the ignition curve. Just saying +4* is ace is wrong IMO better than standard granted, but I guess it all depends on what you want.

And before the shit stirrers come out, it's by no means a dig at Roger as +4 is better than nothing.

I hate it when the shit stirrers come out!!!! There always is a know it all, who thinks his opinion is king

Wish there was a better way to see what works when it comes to ignition setting other than on a dyno, with someone who know what they are doing
