I just got one and am awaiting on some parts for my buggy so I can start her up. I have heard it has good bottom and awesome mid but the top end lacks a bit. It keeps up on the straights I heard but it doesnt blow by anything. The quality of italian mills though are unriveled and for 209 you cant beat it(hopefully)

Just picked up my Promokit the other night. Can't wait to get this baby installed and fired up. Out-door season can't come soon enough.

No real point to this post, just excited to have a brand new, high-end mill in my buggy.

Just started break-in and the compression is as tight as a frog's butt. Heated it up to 200 which loosened it up. The bottom end was rich as hell. I had to turn in the needle to 2 full hours before it would get started. Using the 6 restrictor. I had to raise the idle just a hair to get it right, but when it started it was a breeze after that. It kept it's tune and stayed on temp at around 190 on the cooling head and 180 on the crank case. Going into my fourth tank now. Hope all goes well.

BAD NEWS FROM NEOBUGGY GUYS


This morning rumours surfaced of engine guru Mario Rossi splitting from GRP Gandini, having joined them late 2005 to develop their engine line, starting out with Ninja, Falcon and Boss, and last year GRP's own 'brand' engines as well as the Mario Rossi Tuned versions. Mario was in contact with Neo Buggy and sent us the following statement:

"Hello everybody, this mail is to inform you that I have left GRE (Gandini Rossi engineering ), the factory that develop project for GRP. I want to take a period of time to stay with my family. I would like also to thank everybody I have worked with.
Sincerely, Mario Rossi"

Just as I bought another GRP from Amain Hobbies! F@#$%^!!!

So what does this mean to the company? Will it close?

grp was grp without Mario Rossi, but if i was bettin i would think there would be no more tuned motors, if thats the case i think grp wont last much longer,

Did mario rossi tune everyone himself? If he didnt why wouldnt there be anymore tuned motors?

You think that the 086 will help, the top end any

Ya I have that pipe as well but I really cant say yet. Everyone is recomending the 053 pipe though to me. What I am going to do is run it with the 086 for a while and take it to the track and if I feel like it needs a change I will get the 053 to test against. I may just gte the 053 right now for shits and giggles

if he didnt then i dont see how they can call them mario rossi tuned motors.



i love the 053 on my grp, it has a smooth powerband and great milage

So whats the deal? Will they continue to be made or should I tell my buddy to not get one?

[QUOTE=losi_racer;5520001]if he didnt then i dont see how they can call them mario rossi tuned motors.

Does Kernal Sanders tune the friars that make your KFC chicken?

I've got four gallons on a GRP tuned. I dont race every weekend. After 2 weeks of sitting it was un-tunable today. I began systematically going through the obvious things but the same result concluded. Motor would run good, then go "dumb" rich. I was told by a very knowledgeable person that this is common and it is due to needle o-rings(idle and high).

Motor has ran for a couple weeks at 2.5-3.25 out on the high speed needle with the bottom as lean as I could get it. The motor wouldnt run until I leaned the top. Is everyone throwing their motors away once this happens, because I havn't seen anything resorting to these problems here, I hear of the mystery flame, but no fix other than buying another brand of engine? If I set the engine's needles as losi claims, it wont run at all, after four gallons. I wish Drake Would respond to my "real world" totall screwed situation.

(MOTOR HAS TONS OF PINCH)


My question to the board is, are their any mentions of any of this, here?

Hey guys what pipe works best on the .28, and will one of the dynamite models work ok. Im on a budget and it seems like the dynamite are a little more reasonable. Thanks

i dont own a .28 but i used the .21 in my truggy(its mainly in the buggy) and the 053 was a great match, i got 12 min run time
