I have the DYN 053. What pipe will give me good power and good mileage and not cost more than my buggy? This is for the .21 tuned.

I run the JP-3, good overall power and just about 11 minutes with the 6mm restrictor.

I really like this engine, the power delivery is very linear and smooth, unlike my JPX .28 which was an on/off switch:lol: It also runs very cool.

any tips with this motor? ive been racin a used 1.0 8ight w/ the mach 427 and just sswitched to the go .21. But i just bought a 8ight 2.0 im going to start racin after the first of the year and i bought a GRP .21 tonight and will prob start breakin it in around christmas time.

i used the associated 2035 on mine when i was running that engine, it was really strong and good on fuel, i liked the 6.5mm restrictor better then the 6.0, another good choice on pipe is the 9853/053 pipes they work really well on this engine, i used the grp pipe that come in the promo kit and i couldnt get the performance i was looking for

thats what i was thinking ...i mean the dyn053 looks like a carbon copy of the 2053 grp ....so does the efra rating mean that the internals are different ....i mean the grp pipe looks nice and shinny ..but i mean the dyn053 hard coated looks infinitely more durable ....im gonna at least try it ...i mean how much less fuel mileage could i get .....????

i think it will work great

i have the original Ninja pipe...how is it different than the grp pipe.

Bigedmond 12-08-2008 09:57 PM

The GRP engine tool set is the best thing ever. 5 minutes and the motor was completely torn down, and bearings removed.

cjm1126 12-09-2008 06:39 AM

if you have the ninja 2053 fls its the same exact pipe as the grp

Well, my GRP .21 dropped the bottom of the piston after about 3 gallons this weekend:mad: It was a good motor for fuel mileage, but simply did not have enough bottom end poop for truggy after everything I tried. Tried stock 2053, JP1, JP3, and settled on 2035, and up in spur down in pinion.

So long GRP, it's been a fun venture, but I need more bottom end poop for my truggy.

Anyone that would like some GRP parts PM me. I have a 2053 pipe Case, Carb, Back plate, Crank, and Head that will go to eBay shortly. I'll gladly sell here first. Let me know what you are interested in I can send you pics we can talk price.

ABURTON 12-09-2008 11:23 AM

can you take a picture of the idle screw side of the carb as it came of the engine? How much for the carb?

thanks!

Alan, YGPM, don't be shy on an offer.

fiveoboy01 12-09-2008 06:33 PM

They do make a .28:)

cjm1126 12-09-2008 07:02 PM

mine had plenty of power for my truggy, i found that you have to tune a little more with the lsn then the hsn

Wow, they make a .28, wish I knew that before I bought the .21:lol:

And yes I understand how to tune. Trust me it's not the tune.:rolleyes:

This engine is great, not putting it down. No one should have to run a .28 for the bottom end poop I now am looking for in a truggy. In a buggy this thing would kick ass. Maybe I got a lemmon. Not sure... moving on...:nod:
