Hey guys, anyone have a new tuned conrod for the .21 that they want to sell?

Ive had my eye out for one for quite some time....no luck over here.....Ive seen a few over the month's....but im not paying 60$ for an obsolete motor...sorry no thx.

Yeah, I've been looking for some time but no luck. But the deals on ebay are so hard to pass up. My pops won two brand spankin new GRPs for $200, but the seller removed the rod on one of the motors and now he's looking for one.

you must have missed my post 5 posts up :lol: too late now though its all gone :( i ended up selling the conrod and the other goodies for 65 ...wished id a known you were looking for one

No worries bud...its for a .28 ninja that will more then likely sit on the shelf for the rest of its life....i don't for see myself running it in anything anytime soon....keep me in mind if you do come across one for cheap tho. :nod:

Ive been running a MR-B01A in an MBX5T this season and it has suffered from a lack of bottom end. I have used a 2050 and 9853 pipe on it. I switched to 1.1 spings and it helped a little. This past weekend i tried a JP-1 pipe and it really came alive. It definitly lowered the max rpm but im ok with that for now. I ran a 10 minute heat and still had some fuel in the tank without a pit stop. I have heard that the JP series pipes are fuel hogs. is there a better low end pipe i should be using?

thanks, Steve

os 2060c pipe works awesome on these engines

The GRP pipe 3009 is a low end or high end pipe?

thanks for the reply agro, ill be giving one a try.

Help with Dead GRP .21 Tuned
 

I'm hoping someone can help me. At a race last weekend, my GRP tuned .21 engine in my buggy completely died. Both I and everyone else thought it was the glow plug because it would run on the starter box with the plug heater on it, but then it would die once I took it off. I replaced the plug with a new one 3 different times (P3 and tried a P4), but it kept dying once I took the heater off.(I'm in Florida, so the outside temp isn't an issue) The engine only has about 3 1/2 gallons through it, ran very strong and has plenty of pinch left.

Can anyone give me any advice as to why this is happening and suggest a fix? I appreciate any help I can get!

were the plugs you tried brand new ..i had the same thing happen with my p5xlt and it was the plug ..im just sayin thats what i would think ...i ran grps 3 of them all last season and i never had a plug die or my motor just die ...but i run odonells plugs ;)i would maybe pull out the p/s make sure no foriegn matter got in there as well ..honestly sounds like a plug

I saw that GRP is now making glow plugs. Hopefully a sign that they'll produce parts in the future, especially since they're in high demand.
