Don't know what motor or nitro % you are running, but if your running 25 % or lower, dropping the head clearance by say .2 mm and then going to a slightly cooler plug will get you a bit more run time too.

I am running a GO 5 port turbo with an o86 using torco 30% it has a high castor content I ran it last night with 7.0 tuned it to run 240 should I go hotter first . what temps do you all run on go 5 ports? I used to run250 + but I though I was too out of control but that was before I had a Losi too.

If you want fuel mileage you need to run it 250 deg. plus but it can be a handful on some tracks. Modding it would help, you could try the losi steel flywheel.

I recommend the 3 port race for the beginner to intermediate racers, it is just very smooth but still fast enough to win at the expert/pro level.

Most advanced racers want a little more bottom end than the 3 port has, at least around here. I think the best buggy motor is a retimed 5 port. I charge $15.00 to retime a motor, it makes the 5 port smoother on the bottom and gives it more top end. Fuel mileage seems to have improved also. Best thing is it can be put back to stock easily if you need more bottom end.

I race buggy and truggy..Most likely it will will be mounted in a buggy most of the time and mounted in a truggy on occasion.........I race on tracks all over california so a specified track surface can`t be said....I can say that most pf the tracks are in the medium size range..Nothing here big like The Farm or Nitro Pit...I am a fast intermediate/slow pro driver..I know how to use everything a motor has to offer...Right now I`m running a JP mod OS v spec.....

Dunno why, but I have a hard time getting my head around the temps on this motor. Guess its because every nitro I've run so far is better to be around 230-250 tops. I see 250 (still breaking it in) and I freak a little bit.... I need to keep reminding my self, its OK Bear, its OK

Forget about the temps. Tune it so it runs good. If it's running good, with good exhaust smoke right through the rev range, then whatever the temp is at that point is fine for that motor / pipe / plug / fuel combo. If your tuning to a specific temperature range (that someone else runs at) you might be leading yourself up the garden path. Different oil percentages etc can make a big difference in running temps. Leave the temp gauge at home, that's what all the gun tuners I have ever come across say. Not one of them has a temp gauge in their tool box (just the good old spit test) and their motors perform flawlessly meeting after meeting. Just my .02c worth from what I have seen and been told.

Yes Matt - fully interchangable

I charge $15.00 if you send me the piston and sleeve, $35.00 if you send me the whole motor. (includes any work needed) Both prices include shipping back to lower 48 Us.

Hey xxx-t, to post in a thread just scroll down & just under the last post on that page, on the left side you'll find a rectangular black button with white text that says Post Reply. Just use that to make general comments etc. Use the quote buttons if you wish to respond to or comment on someones post.
Just a bit of help for you :)


Pete.

Well I just got done changing over the con rod in my ebmodded 5 port. also did the wrist pin and snap rings. I also put on a gen 5 or 5.5 carb, has the red go in the front.Talk about a monkey fk'n a football! I am surprised the thing runs. Grizz thanks for the instructions on how to do this. Thank god I did not erase your email message. The biggest thing I fk'd up was taking the sleeve out. I put the zip tie through the back of the exhaust port, instead of down the cylinder to catch the lip of the cylinder. Got it all done and the engine did not want to run. I put in 20% nitro,this one likes 30%. still no go, switched carbs put in an os p-4 plug 20% nitro thing rips. This engine now that it is fully broken in and tuned is way to much for me let alone a buggy. I may put it in my wife's x1x jammin as it is heavier then the hyper 8.5 that the engine is in now.I am going to have to think about it. I may try it in my x-2 jammin and see how it makes that buggy react. I'm going to reseal the old carb with the seals I got from massive mods make sure it runs good and holds a tune then sell it. I am thinking 165.00 shipped lower 48 only. This really belongs in a truggy.:weird::eek:
