Hi all - I'm 18 tanks (2.5 litres) into my new 5 Port .21 and have a couple of questions.
Took truggy out to the track today and gave the Go tech it's first proper run on track (up until now it's been slow running in and some 1/2 to 3/4 throttle stuff on the last few tanks before today).
Engine still seemed pretty tight and not overly responsive. I fiddled with the tune a bit, but couldn't really get it to pull in the lower rev range all that well. I'm sure the tune was not too far off. I am running a JP-3 pipe which I am thinking might be part of the problem (Dynamite 086 and 053 on the way). I have read in here that the JP-3 is not the best pipe for the 5 port.
Is the engine likely to still be "tight" and sluggish after 2.5 litres ? and would the pipe make that much difference ?
All my other engines have been sweet after 12 - 15 tanks, but this Go Tech is still nearly impossible to turn over by hand, with enough pinch to jam it solid on the starter box still. This is obviously my first Go Tech engine so I am a little curious as to how everybody else found them during break in and early running.

remember to remove the shim when the engine breaks in, you will know this cause the temps will go way down and then its time to remove the extra shim...

not really, but after the temps drop and its a big drop 40 to 50F, make sure if your racing at that time that you DO NOT make any real long full throttle runs until the extra shim is removed...

Thanks for your replies guys. I am not running the shim. The shop I purchased the motor from told me I would only need to fit that shim if I wanted to run 30%, no mention of using it to assist with the break in 
Sounds like it makes life a lot easier. I will fit it tonight and give the beast another run on Sunday. Thanks once again

Thanks for that Jason. It's hard to get good help these days !!!
These guys are Go Tech agents, so should know better.
Hopefully I haven't strained the rod too much without the shim in. On reading some posts here I will probably change the rod at 2 gal just to be on the safe side. Cheers

Ran 5 port with shim fitted tonight. Big difference !! Behaves a lot more like a fully run in motor. Tunes easier and seems to run nice right through the rev range. Like salteen said, the difference is like night and day. I am much happier now
