slobanshee Posted March 17, 2012 Report Share Posted March 17, 2012 I recently got my a&s ported 10 mil cub together and wanna go ride at spring break. So for now it has 30mm mikune carbs, Cpi inframes, 180 compression race gas, +5 on timing, v force reeds. I have 30 pilots and 360 mains. It seems to pull up top ok but before powerband is doggy. This was my first bigger motor and on a +8 swinger it's not as impressive as I'd hoped. Quote Link to comment Share on other sites More sharing options...

This was my first bigger motor and on a +8 swinger it's not as impressive as I'd hoped. what is it doing? boging out at low rpms like at take off from a dead stop? sounds like a jetting issue. what kind of air filter? stock air box? lid on or off? what temp are you riding in currently? we need more info. you said it seems to pull up top ok? my 4 mil with a full dune port from hjr pulls like crazy especially at powerband. a 10 mil thats ported should pull like a train. you should def do a plug chop and see if your running too lean or rich. new plugs always help too Quote Link to comment Share on other sites More sharing options...

Its responsive low throttle. Mid is very boggy and power band is there but nothing like I'd expected. It revs out but slowly compared to my old stock stroke/bore. I'm in a small field testing. There's little to no room for a chop. I can get 1-3 maybe if it can get stopped. Quote Link to comment Share on other sites More sharing options...

slobanshee Posted March 18, 2012 Author Report Share Posted March 18, 2012 They don't answer very often for me lol. It's brand new.. I feel like its a jetting issue to just looking for a direction. Thanks Quote Link to comment Share on other sites More sharing options...
edgehanger Posted March 20, 2012 Report Share Posted March 20, 2012 I think the carbs are a bit small for that motor. Im assuming you have big bore cpi's. Those 30 mm are holding the motor back. Just my 2cents. Quote Link to comment Share on other sites More sharing options...

bigboybanshee Posted March 20, 2012 Report Share Posted March 20, 2012 Your biggest setback is the carbs and pipes. You should invest in at least a set of 35's, but I'd go 39's. It's like using a straw when you need a garden hose. Cubs like fuel and it's not really fair to judge the setup until you give it what it needs to run at full potential. Shearers make an excellent inframe as well. When you get the setup right, that ported 465 will use every bit of that swingarm. You could try and tune more on the needle and mains, but I honestly don't think you'll find the power you're looking for without giving it the proper amount of fuel. Once you get more fuel to it, you can also bump your timing up and gain a little more power. What about your clutch setup...what are you running?

barahonapr Posted March 21, 2012 Report Share Posted March 21, 2012 Like said by everyone else contact your builder. I had my 4milson serval done by jeff and he recommended 35s so i would imagine that a 10mi needs atleast that if not bigger...just my opinion..
