your rite they do say pinch the fuel line i usually do this at the end of the days racing just to burn all the excess fuel out of the carby and the engine

TO ALL U GRP LOVERs. sad news

Sounds like insurance fraud

Yes, to convenient

Does sound a little fishy.

mmmmmmmm your rite sounds very strange or conveniant
any way sad news for all

one can only assume that now it will be even harder to get spare parts .....

weird thing is that a lot of stuff that was out of stock, is back in since yesterday @ Amain, thought they weren't going to stock up on anything, at leas that what a rep said last time I spoke with them, "once it's out of stock, no more"......

grp factory burned down..this will realy suck for them now

Probably arson done by a disgruntled ex-employee.

From the article:
News: We have been told by a source that certain machines were moved from the factory last week, and some employees let go.

Yeah, GRP was either downsizing and laying ppl off, or relocating and laying ppl off.

Article Update: The newspaper reports that the fire broke out in the factory's boiler room, an off-duty police officer spotted smoke, passed by the front of the building where one of the Gandini owners were, they went together to locate the source of smoke and found a broken window to the Boiler room.

If this happened late at night, it was convenient that a Gandini owner was there, huh? *cough* insurance fraud *cough*

Still, sucks for the employees and the loss of Massa's old race car.

Regarding my GRP MR Ninja B01A:
It seems to lean out quite early, doesent settle on low idle, it revs up. However the temp is low, and its screaming nicely at top end.
After a while and with full tank it settles on nice idle after a while.

Is the sollution to lean the LSN further, and adjust the idle screw, or do you have any other ideas?

In my GRP Tuned .21 the piston skirt broke right around the 2 gallon mark. So I put a new piston and sleeve in and I'm currently breaking it in. It's running like a dream. Pre-heat to 200 deg. F and then starts easy. The temps settle to 180F and stays within 10 degrees of that. It's just awesome. The idle is perfect and I couldn't ask for an easier break-in period.

The very first time I tried getting this engine going was a big pain in the rear. But since the rest of the engine has about two gallons and only the P/S are new I assume it's just that much easier to break in.

I used some DOW Molycote O-ring grease on on the needle o-rings and they don't seem to move one bit. The tune is staying very consistent and each change of the needles does exactly what I want.

I also had suspected a front bearing leak because of all that I had read on this thread. But I tried the Brakecleen sprayed near the front bearing and the idle didn't change one bit. Nice. So since this is all going so well I can only assume something catastrophic down the road soon. LOL. But I hope not.

HSN, 4, 3&3/4, 3&1/2, LSN 6, 5&1/2. ???????? Whatever. I'm not doubting any bodies ability to tune an engine here except for myself. Those brushless motors are looking good right now. Bloody NITRO love and hate it.
I am missing something here, i've lost my tune and my marbles. I gotta race tommorrow and I really hope it is my usless tuning and not an underlying prob. Hopefully our club guru can get me goin good. My motor was going great guns, don't know where the needles were but it was better than where I can get it now. I had a serious lean bog and no bottom end but at least it idled forever.
It's goin like a shower a shit, pleanty of bottom end now, just don't crash cause she's gonna flame out waitin to be marshelled.
Now before anyone starts givin me needle settings you must know I'm on East coast of Australia in sunny Queensland, just switched from 20% to 25% and using O'Donnell 97T plugs.
I HATE FLAMMIN OUT AND DNF'S

noone should be giving you needle positions. if they do they dont know what they are talkin about unless they are for stock settings.ALL engines will be different on tune even if they are right next to each other

Yeah this episode has brought me back to basics. after too much reading and not enough doing. I think i've been too concerned with the LSN and I have been taking the HSN for granted. Been told it does not affect the Idle tune but i'm not convinced. I've just been leaving the HSN set at around 4 or bit less but not actually tuning the top end properly and doing the WOT runs and leaning the HSN to optimal. It's still producing top end power but probably not it's optimal. Hard to tell still goes pretty hard. I think I'll be resorting to basics first thing at the track tomorrow and lean that HSN needle out to optimal first and then finesse the LSN. The club guru has said he will have a look at it for me but that does not improve my tuning ability. I do beleive the HSN set to rich has to have a direct affect to the LSN and idle. It moderates the amount of fuel on hand for the LSN to govern.
