Interested to hear more on the D52.

Finally got to race my A52 this past weekend.. All i have to say is SweeeeeeeeeeT.. This motor frigin ripps... Now for the weird.. I was runnig a jp3, motor ran well, all of a sudden sounded way fat and shut off, thought i lost a plug, changed it, same thing, to make a long story shorter, swapped engines, and had same prob, turns out pipe went bad.. changed pipe, everything fixed..Never seen a pipe go bad before... Here is the question.. I had to run a jp2 and OMG the buggy had stupid bottum end, can a pipe have that much effect on it?? the jp3 had plenty of bottum but was not as violent as the jp2, unless the jp3 was going bad and restricting... Ive run this same clutch setup before and never had this much snap on the bottum end( losi buggy stock springs green and gold with dynamite maxlife shoes) I know im not keeping the jp2, Im either going to a jp3 or 4, just wanted to get opinions/thoughts...

The A52 runs quite well with the JP-4.. Great run-time..

In the UK the A52 was/is sold as a combo with the JP-4.. I.e. it fits well to the engine..

I tried one briefly in my SC8 with the Argus, but it lacked a tad on top-end. To be fair though, the engine was still pretty early during break-in, so I need to test it again.. Took forever for the tank to finish, and it DID have a very nice, smooth, linear feel to the power... The 0801 is punchier - a bit more explosive.. So I can imagine some people might even actually prefer the JP-4...

Here's a short vid of my Argus A52 with JP-4 in my SC8.. The engine probably only had a liter or so through it at this point - maybe two..:

The pipes do make that much difference. Any pipe will work with any engine...but it won't be optimal. That's why the guys distributing an engine give their recommendations. And it's also why most will distribute those recommended pipes.

sounds awsome guys...

news is that ill have the A5 and B52 in my hand early next month to test with my EFRA 2072 sooo looking forward to that...

will post pics and mabe even video snips.. although Argus had a short run / wasnt available locally for long.. due to mistakes by importer & disloyalty by driver who was given every oppertunity...

other than that i hope these babies hit the aussie market soon as they have alot of potential... with the right people behind Argus...

Its a shame Aaron Stringer jumped ship, he had some pretty good results with the A52

Hey Jay Glad you like these little mills (Agrus). Now you need to try some of MY Fuel "Force Fuel". We've been working on it for 2 years and have it ready for limited production. where going to ramp up slowly so we can maintain our quality control. We have blended it for the needs of the SE USA, mainly FL. you think you have snap know just wait. give me a yell when your ready for some i will take care of you.

yeah real shame... guss its better to trial and then see how things go before handing over the "pot of gold" all in one go...

keen to run these 2 in so i can show case them at a few races and gauge reactions and create interest from racers n shop owners...

great engines , very competitive pricing... etc... all good from what i see or read...

What kind of oil mix do you use? I have went from byrons to stike team tried S &W now going to Powermaster. Strike team and S&W are great fuels but all syn oils.

Lance I have a question on the A52s I bought from you. I have them installed in my buggies and on my racer I have the modded motor. I was doing some center diff maintenance and when I looked at my motor the front area was wet. Now I havent ran the modded motor but 3-4 tanks could the front bearing go bad that soon?

Front bearings will leak during beak in or when when running very rich, What happens is the excess fuel and oil from being rich is sitting in the bottom of the case and the crankcase pressure pumps it out. if when you get them broke in and leaned out should stop.

Thanks,
Lance

The two Argus A52 I ran last season both had that happen during break in and early fat running. Like Lance said with Race Tune I had no issues with the stock bearings. I actually felt like they are pretty good bearings for being stock.

yes, they are actually very good. Most of the time they last the life of the engine which has been Approx 8 gallons or so.

I had issues with the front bearings too (A52 modified) . I noticed that after about 6 tanks. Could not hold a tune for more than 5 min. One way to find out if you have a leak is to plug the exhaust and the intake of the carburetor with your fingers, and open the high end valve 5 turns. Then spray the front area of the engine where the bearing is located with a mixture of dish soap and water. Then blow air into the fuel tube line. If you see loots of bubbles escaping between the crank shaft and the bearing then you have a leak. That is how I found out about mine.

Long story short after I replaced the bearings with high quality bearings I have no more problems. I have about 1 gallon though and the engine is fantastic. In fact, it gets better every time in how it idles and the amount of power it produces. I'm sold on this brand.

Something to try if you haven't already is to cook the pipe in antifreeze. I use a small crockpot on high for about 24 hrs. If its an anodized pipe the cleaning will remove the clear coat so the pipe won't be as pretty but it may be useable again. I've cooked a few pipes for myself and others and a lot of tuning issues have been cured. You may be surprised how much gunk will come out.
