Does anyone know what size carb restrictor comes on the .21 promo kit setup? If I'm reading the online manual correct it's 8mm? I wanted to get some smaller ones when I order the engine.

My Promo Kit tuned .21 came with aall the restrictors.
Cheers

If you want to buy a single carb restrictor just look for the old ninja engine parts on A-main. They aren't that cheap but if you just need a specific one.

Quick question for anyone that has the GRP engines running them in a RC8. I thought I read somewhere that you need to get some setback eng mounts to get everything lined up and was just checking to see if this is correct?

Just got my .21 tuned promo kit :sneaky: Getting ready to install now.. tomorrow, the break in begins. Pretty psyched about this one! :nod:

I run it in my RC8 but I can't say because I run the Xtreme 2 piece mount and I don't have any probs with it.

Alan Burton,

If you plan to come to Arkansas with Jeremy this Saturday, can you pm me and let me know. I might need a little tuning help my GRP. This thing doesn't tune like anything I've ever owned.

Yep the GRP plug that was installed was dead out of the box :flaming: Got through two tanks of idling so far without any real problem.

i use os plugs, i blew thru 2 grp plugs during break n, and since ive been on the same os plug and i have about 2 gallons on my grp. im going to switch to a p4 plug tho so it will have a new plug. My dads grp blew its grp plug on the first tank. grp makes GREAT motors but there plugs need work for the money you spend on them

mattwoodcraft 02-25-2009 01:11 AM

These grp tuned engines are the bomb extremeley happy :nod: look good good price with what you get in the promo kit cant complain at all :nod: so much better than my os v engines i usually run :)
