Guys, any advise?

I take the Brake in Shim out and Then Run a P3 Plug Has always worked well for me. Have one of these engines in my Truggy for almost 8 Months. It Rocks!

Anyone experiencing high temp with os2060 pipe, fuel economy was excellent. Guess i switch back to arrow 2103 pipe

No i always have used the Aarow Pipe.

In buggy with 2103 pipe, usully how many minutes can get?

Mine will run 11 to 12 minutes.

looking to pick up one of these engines but don't know if to get the v4gtr or the gtr plus. i will be running it in a buggy, any advice greatly appriciated .

Gtr plus, more aggressive. Fuel consumption almost same? But more power = higher fuel consumption

gtr plus orion 2013 at about the half gallon mark almost able to turn over by hand, p3 plug traxxas top fuel 20% getting 10min exactly.. couldn't be happier with this engine.

What are the factory carb settings? Having a hard time getting a good tune on this motor and want to start over needle wise.

I had a hard time tuning it till I found here that the mid needle should be out 2 turns from flush.
Low I usually start with flush high with 2 1/2 turns out from closed. Should be somewhere posted from vppro in this thread.

Well I figured out what my tuning issues were.

After taking apart the motor I found the case was cracked at the mounting tab, lengthwise. Small air leak causing it to run hot and stall out.

Probably just going to order a whole new motor. Get the Plus version this go around and order a new case later on as a backup.

Had that happen before, replaced it with a os case, it also cracked. After a while my motor was arrow / ninja / os Frankenstein. Still run it in a truggy after prob 8 gallons. The arrow gtr plus v4 is a strong little beast after two gallons in my buggy.

Do you still have the break-in shim installed?

Yes I do. Prob take it out this weekend.
