dang i got a SMOKIN deal last month from Amain.the promo kit for $299! somehow when i ordered the motor only..it was backordered and i was still able to order it... a guy from Amain called me and said they would ship the promo kit for the same price as the sale they had going on the motor only.. i love the GRP pipe...not having shaped gaskets connecting the pipe and the header is awesome!!

many thanks to Amain's customer service!

I need some expert advice. I screwed up the rod in my GRP from what looks like a stray plug element and it chewed up the the rod end at the crank and took out the bushing and also chewed up the backplate quite badly. It also took a few small chunks out of the piston, but aside from that the sleeve looks fine also the case looks ok with just a few metal shavings laying in it.
Ive included some pics to help you get a look at it(Ignore the time stamp, the cam is not set up properly):

To fix it would need a new rod, backplate, piston and crank.
At the end of the day if i need to replace all that and with the amount of fuel through it(around 20ltrs)it would probably be cheaper to just salvage the ceramic bearings and carb and buy a GO engine or something.

Engine kits from 330 to 250 euro -25%
Buggy tyres from 20 to 12 euro -40%
Engine tool kit from 139 to 80 euro -42%
The new pricing policy will start somewhere in february.
I don't know what the situation will be in North America but I think you can expect the same sort of discount.

Please note the red text
Italian company GRP Gandini have announced drastic plans for 2009, including slashing prices by 40% and more. The 'Price Reduction Program' will come into effect in January and will result in removing some steps in the traditional distribution chain. GRP's site will sell products direct to the end-user, in a bid to save the company, as well as saving the end-consumer some cash.

GREAT NEWS FROM GRP FOR 2009
WORLDWIDE GRP’S PRICE REDUCTION PROGRAM
This program will be launched officially by GRP starting from January 2009, to contribute to facing the serious worldwide crisis which is involving basically all sectors.
Our idea is to make available on the market, all GRP products of our Tyres, Engines, and Gadgets lines, with the best quality ever, at very much reduced prices compared with our 2008 price list.
This price reduction is possible by reducing to a minimum our margins, by removing some steps in the traditional distribution chain, and by accepting a reduction also of their margins by all those who will agree to our program.
In this way we intend to widen the range of end-users, who will be able to purchase now, at advantageous prices, our top range products. The main points of our new GRP program are as follows:
- Optimization and development of our current production unit in Guidizzolo, with a consequent further increase of our quality product.
- Equalized retail prices all over the world.
- An average retail price reduction by over 40%.
- Purchasing of our products in all the hobby shops that will support our program.
- Purchasing of our products from the new official GRP’s e-commerce.
- Direct purchasing at race events whenever GRP’s staff is present.
- Direct Technical Assistance on behalf of GRP, for any eventual technical problem under guarantee, and for the standard engine maintenance.
- Direct Technical Assistance at race events whenever GRP’s staff is present.
- Direct Technical Assistance on-line on behalf of GRP.
All new retail prices will be published very soon on the new GRP’s website, together with all numerous novelties foreseen for 2009. Here some anticipation:
- New .21 carburetor which improves fuel consumption and eases its carburetion.
- New Tuned Engines, with various improvements in terms of material and treatments.
- All Tuned Engines will be available on the market also fully run in and checked, ready to run.
- New stiff and light wheels for 1:10 Touring tire line .
- New big and light wheels for 1:8 Buggy tire line.
- New shaped black inserts for 1:8 Buggy tire line.
- New X compound (like PL’s M3), for 1:8 Buggy tire line.
- New Cubic design for 1:8 Buggy.
- New narrow Jolly design for 1:8 Buggy.
The official presentation of all our new GRP products for 2009, and the launch of this new pricing program, will take place on the occasion of the coming Nuremberg Fair from 5th to 10th of February. Our new GRP e-commerce will be up and running starting from 15th of February.

i have a grp tuned .21 motor. ran it all last year about nine ten gallons on it. great motor loved it. needs a rebuild piston sleeve rod. is it worth rebuilding with this much fuel through it. motor ran prefect never missed a beat. just dont know if it would be worth time and money to rebuild or buy another. has anyone rebuilt one yet?

Does anyone have the measurements for the GRP manifolds?
Like this but GRP:

The thing is that i got the old Ninja MR21 made by GRP and i want to move the pipe inward, the one i got now is the old Ninja manifold made by GRP.
Its 82mm wide. The car is Mugen MBX6 and ye it is tight.

Jonro, Hate to tell you this, but the tune was off on that engine.
The piston has been cooked, and detination from being lean,and more than likely the lean condition has hammered the rod bushing out and changed the compression and timing, which in turn burnt the glow plug out.
I would not salvage anything out of that engine other than the carb and head!
Adam Drakes tune on this engine is:
.045 in from flush Hsn
.045 out from flush Lsn
.030 in from flush, idle screw
6mm restrictor
GRP 5 plug ( I run a GRP 4 plug)
2053 GRP pipe
The engine will run between 150 to 190 degrees(nitrotane,30%)
Good Luck
