Alright so I'm going to FINALLY be building my mini/ap up soon and want to comply with both major organizations rules. In the Uslmra's rules it states max of 22ci. Ok so that means I can run my tvm 220. But I also have an 8hp briggs I need to put together with a Don G stroker crank that puts my briggs at 22 ci would that be legal in Arma. I know my 220 wouldnt be.
The Arma rules says 8.5 hp and under and 19 c.i. but im not sure If I'm allowed to increade my 19 ci briggs to 22ci. Help please.
Thanks

Sorry for the spelling im on my droid

Whatever happened to Don? Last i read from him is he was about to get flooded over the summer. Any recent news or contact info? Is he still in buisiness? Sorry I have a curious mind.

Like the title says, how do you break in your motors, I wont post my twostroke info here because we dont have twostroke classes, if you want it pm me.
as far as me and 4 strokes, i havnt built to many yet, but regardless my theory in breaking my motor in goes like this. when assembling check everything ALOT of times, clearances, ring gap rod tollerence etc all of it. put real cheap lightweight oil in it and spin it by hand and if aplicable rotate the motor. then drain the oil, this will remove most stray particles. then run a good lightweight oil or breakin oil and start the motor up for about 5 minuetes and let it idle. while idleing check for leaks throught out tthe whole motor. once the motor gets warm, shut it off  and allow time for it to cool, while cooling change your oil and run what your going to run everyday, now this time start it up and ride the thing like your going to ride it at all times, so what i mean in lawnmower racing is get in race gear and get to wot and let the motor do all the decelration, in short this will cause pressure to seat your rings closer to your cylinder walls than slowly building up the rpm, and what this dos is allows your rings to hold more pressure and not cause as much blow by due to poorly set rings. The first about 20 minutes in a motors life is one of the most critical in how its going to run is what I've been told. this is just my theory dont bash me for it, if you want to post your way up Please do so, if you dont like my way state why, i find breaking a motor in the most controvercial part of building a motor, every one does it a different way and know one knows what the "best" way is.

Hey guys I have a peerless 350 I'm going to run on my ap. Where can I find a front sprocket for it. I know don runs 1:1 pullys then I was thenking 24/46 on 13s does that sound right? Thanks

Hey guys I was wondering if any of you guys are interested in a billet 4140 crank. I'm planning on making one for myslf on the cnc. And if anyone is interested I could POSIBLY make a limited run on them. This is not a for sure thing I'm just checking interest. Thanks

Hey guys, my cousin has 2 gxv340's, he sadi he would give me one, So i read all i could and I know the v means verticle shaft. I also read that the Gx390 Billet fly wheel and rod will fit this motor, I'm wondering if thats correct and also I'm wondering if the blocks between the 340 and 390 are the same just the 390 has a larger bore? So wjhat im trying to figure out is could the 340 be bored to fit the 390 piston? thanks for the help guys.
