Thanks.... Is that all?

an o.s. plug might work or might not as far as leaking goes. i have heard that sirio plugs work, but i have not tried one yet.

best thing to do is go with the plugs made for the engine Chill. They are not the cheapest but I feel they are the best for the engine. If you get them in the 5 pack you save some dollars.

Well I don't get them free so I try to save when I can.

i use the p3 with no problems

I have switched to the OS plugs also, and have not experienced any leaking. I can imagine it being possible if trying to go back to the GRP plug, but I dont have a reason to at the moment.

i have been told by GRP drivers that the os plugs work fine.

Thanks guys

late ...im gonna stick with odonells plugs ...they have been good for me and priced right ....the last grp i saw ...the plug was bad out of the box ...now thats not knocking the plugs ....as im getting a grp ...but have had much better luck and longevity with o.d. plugs ....between 99t,97t,77t i oughta be good for our environment .....and thats med-cold,med,hot

Odonnell 097T here in my Ninjas (GRP made)

So you saying the OD plugs work too?

couldnt get mine to tune right with the grp plug #5. Switched to a p8 first and it tuned better, but since switched to the jx p3 and it runs great and rarley flames now. I really like this engine, very smooth power.

Have any of you guys tried this engine? What did you think about it?

Anyone have any carb restrictors they want to be rid of for the GRP .21 tuned? Size 6 or 6.5? Pm me.

Also are there any other brand carb restrictors that will work with these carbs?

A bunch of guys run it where I race, and they love it. I can't think of hearing one bad thing about it. It sort of became the engine of choice at the track I run. Everyone is upgrading to the tuned version over the winter for more power. lol
