I got 1. I removed the gas tank to access sumthin or forgot the 2 hair pins. I started the truck and drove like a lunatic across yard and halfway back it stalls, soo I put ignitor on and yank away for awhile, then get tired and notice that the fuel tank IS GONE! [Maybe it's not getting any fuel?]
I own a LRP ZR30 with a THS 825 pipe and it's pretty fast. I have a 25 with a three speed and a Force .28 and an X with the .30 and a 2 speed and the X absolutely dusts the 25 in the mid-top end. The ZR30 just seems to keep accelorating while the force is all low end

260-270f is warm but IMO probably not too hot. Just check the usual subjects as far as leanin it out, cracked fuel line, cracked fuel tank, bad lid o-ring, carb o-ring,etc. It may be be helpful to return to factory settings on the carb, and retune from there.
Well, I got the half tank licked for the moment. There was something in the HSN that was partially blocking the jet, it was gone by the time that I discovered the prob but It left marks on the needle and seat as evidence. I'm gonna retune soon and shoot another vid:D. As far as the roto start, I...
Check the nubs on the aluminum disc that mates up with the steel disc with holes in it. The nubs go in the holes and sometimes don't get lined up right.
Just a small update, I have a THS pipe coming from SMF. I'm kinda excited to see if this improve the midrange a little. Overall I'm still pleased with this engine after about 10tanks the only problem I have had is really hot last 1/4 tank. Temps go from 180-230f to 295-310f for last 1/4 tank but...
Yeah I have a polished Hpi pipe coming from SMF. I also am interested in the Buku pipe. Do you guys think it would do alot for this engine? I'm using the stock R5 plug, Byron's gen2 33%, 17/47t gearing. I have done no tunig , all settings are stock from the manual after break-in.
