Thanks.
One other quick question... Turbo plugs??? $11.50-$12.00 a pop for GRP's! Anyone know of another brand that will fit properly at a better price? I held a Novarossi plug up to the GRP, and thats a no-go as the conical is different shape and length. I know turbo plugs last long but come on! Help! Where do you guys stock up on plugs for this engine?
