I understand your concern. It took a lot of cojones to ok the "Grenade" name on the motor, but it was a calculated risk that I felt was necessary.

As you proved, the name recognition is there, now we have to prove it is more of an antonym than a reality.

So far we couldn't ask for better results as they are built extremely well, priced fair, and perform on the track with durability.....

i took the engine apart today and the internals still look great! i have heard of some people having problems with the connecting rod and bushing on the GO's but mine looked brand new. so far i'm happy. i will be running it next weekend at nitro fever so i'll have a better idea of how it performs in a race after that.

Just started breaking mine in yesterday. Only got 3 tanks through it before race time so did not run it in the truggy. Ran buggy only. The pinch is CRAZY on this thing. I thought some of my Go's had a tight pinch, HA! Cannot wait to get it ready for some racing!

I did however find my needles set lean from the factory. Had a hard time getting it to idle and had to richen it up alot.

Hey all,

I'm a Caster Driver and from my limited nitro experience I must say its pretty reliable in my opinion. Only 1/2 a gallon of fuel on her but with all the advice from fellow team driver:

1. For break in make sure needles are untouched
1.5 if you decide to touch them the ballpark was flush on both LSN and HSN
2. Heat to 220 *f
3. Make sure crank is at BDC
4. Quickly press it on the box and BAM

To comment on the "getting colder as you run it", I too experience the same things however the air temp in my neck of the woods is 35-45 so it just makes sence for now. What I do to keep the temps acceptable is to wrap some foil around the head and that keeps the temps pretty consistent.

Now when it gets warmer I don't know how it will act but I'm sure someone will have figured it out by then.

As for popularity in my area, I've quite surprised especially with all the hate talking going around with the Caster name. Either its just friendly trash talk but my locals were impressed with it on the track and its price (mill/header/pipe) under $300 I think that's fair.

I hope people understand that I'm new to nitro but with the support for my teammates and Caster I'm sure I'll be taken care of. So if you're the polar opposite I'm sure you too will be impressed with this motor and the support from Caster.

Rudy

I ran the motor at a big meet here in Australia (Bundaberg nitro challenge) it was great did not flame out once, heaps of power i got as high as 6th in qualifiers but qualified 10th only to break my car in the semi finals .When i got home i decided to pull it apart taking the the backplated off i noticed a little slop in the brass sleeve in the conrod, (doesn't suprise me with the amount of pinch) the motor would have about 5litres on it now, i happened to have a new axe rossi conrod laying around and after measuring it all up i found it was a perfect fit, so it will do till i find a genuine conrod, my opinion is the motor is worth every penny if not more!!

since it is a gotech motor ...a couple of things should apply ....it will go rich and sputtering from a decent tune at least 2-4 times before it breaks in ....it would also be recommened to check the conrod bushing ...after the 2 gallon mark ....they have a tendancy to explode ...but if you check it and replace it it will work fine ...also if you move your carb around alot you may wanna replace the o-rings often ....they will tear and your carb will develop the ilusive gotech carb wiggle ...also you can put an extra .10 head shim for break in and it will ease the break in ...im saying this having run gotech all last year ....5 port 7 port 3 port r.....im just sayin ....

thank for an informative post...I once had a go tech 5 port I think like a gen 2 it was hell to break in but super fast i got 2 gallons on it before my rear bearing seized(but i didn't take care of the motor as I should've)...I was a little more noob then...I will be trying one as soon as I can afford it but for now my caster will be powered by a PTM VSpec/Jp-3 combo
