Would a Dynamite 053 and Ofna 086 be close enough?

Funnily enough, those are all the three pipes I've tested so far...

So far the 086 seemed the most promising I guess.. But I was worried it'd lack bottom for truggy..

2058 barks on a Nova p5.........if the engine is soggy on a 2058 I would be looking for other issues..i would also check the head clearance to make sure its not off.....And if you don't know how to do it then its a great time to learn how !

What do I do then? The engine seriously felt like a .15... Temps were 250-260, and I could see smoke.. Is it conceivable that it would have run like that just from having a lean LSN and a rich HSN? Idle was a perfect low pur. That's the only thing so far I like about this engine - purs great at idle, and easy to tune(responsive to adjustments)... But power-wise it has been totally lame so far.. I figured that what I had seen previously was due to running on pavement, and figured once I hit the (rough, blown out, low-traction) track, it'd come into its own or something.

A bit fat NOPE on that though..

Tuning issue..

Is it even broke in yet? I thought you just recently got this engine. I've seen guys say it can take 2 gallons to fully break them in. Just a thought. If you had break in service done to it, that does not mean its done,(break in). Good luck.

I've broken in a bunch of engines in the last few years, from various brands, and all have broken in, tuned, and run well - and still do.

Something is up I haven't encountered before. I don't believe this engine is that much of a turd. I had an older version (REX) modded used one a couple years back, and it ran great (albeit with a 9901/short) This one tunes and idles great, but power-wise, from what I've seen so far, it couldn't hang with a Go 3-port...

Clutch. Make some adjustments or swap out.

Just picked me up a gallon and a half old Beat 5 from a buddy of mines and I noticed it comes with the regular black stock front bearing and not the blue 17011.Thats a little dissapointing and was wondering if anyone is having any issues with the front bearing? It doesnt appear to be leaking at this time but I'm considering replacing it now before there is a problem. Any thoughts?

i would recommend putting new front bearing in it , the less expensive bearings dont usually last for more than 1.5-2 gallons of fuel and can have the seal compromised even sooner by running lsn blubbery rich .

hope this helps

well if the head clearance is out you can probably adjust the shims to get a proper head clearance..........Very recently I have come across a few oddball engines that had the wristpin hole drilled too high on the piston by 0.6 mm, lowering the piston crown by 0.6 mm more then standard, which not only completely throws off the sleeve timing it also throws off the overall head shimming..... The engine had .6 mm more head clearance then it should have...The engine ran amazingly well considering..it idled well and seemed to tune easy, but it had no power whatsoever....extremely lazy on the throttle with almost no bottom end......

That definitely helps and will give me a piece of mind. Thanks!

Hi, I just got a nova btt and was experiencing issues with mounting it. I have a losi 8ight 2.0 and run a werks 34 mm clutch. After I mounted it, the starter box wheel would not engage with the flywheel. I have the losi starter box. It seems as if the flywheel is slightly higher than what I had on the previous engine. Have any of you losi guys had this problem? I know I'd need a different engine mount, just would like to know which one. All help is appreciated. Thanks.

Just space your starter motor higher with some washers under the mounts.

Hey All, racing Saturday I got my buggy fitted BTT WC 2084/41001 a little hot. I didn't have a temp gun handy so went the wipe of spit test. It was HOT as in 15-20min into the 30min run it became extremely sluggish. Sunday I tried to retune and had it idle great both on the box and after a 7min run but couldn't seem to get good poke off the bottom. Pulled the motor apart and all looks good, what might I be missing?

Thanks
Michael
