Anyone running RK tech drop in kit??

[JustinB]

Ok so I want to run the Rk Tech drop in kit on my 02 800 but I am a little skiddish for a few reasons.

11. Do not run the BR9ECS plug run the BR9EYA plugs (Arctic Cat) or BR9ES gap the plug @.020”
Why the different plugs? I thought you had to run the ECS plugs with the mpem?

12. PREMIX a 150:1 oil ratio in 1st tank of fuel. RKT Recommends to always premix at 150:1 in addition to your oil injection system. Break in engine with a mineral based oil and NEVER run ANY synthetic oil in this engine.> Ever!
Why Run mineral Oil? I was planning on running redline why not synthetic oil?

13. IMPORTANT: DO NOT USE ANY aftermarket silencer on this set-up. Use the stock pipe and muffler. This “kit” was not tested with any other pipe/silencer combination.

I bought my sled with an after market can! What now can I still run this kit?

never run synthetic? whaaa? - i musta overlooked that in the propaganda section -i'm saving up for an 827 kit right now....
i've always run shell ultra synthetic in everything (even my morning coffee somedays-LOL!) does anybody know the reasoning for no syn? is it a cost saving benefit or an actual performance issue? (same as with the plugs i'm assuming?) maybe have ta shoot them an e mail....

rk drop in kit

i just put an rk tek drop in kit in my buddys 06 800 ho summit you only have to use the mineral oil for the breaking in of the engine so the rings will seat properly i believe break in is the first 100 miles and then u can go back to whatever synthetic oil you were using ps you have to use either BR9EYA or BR9ES as says in the instructions either one the sled runs great!! my buddys 800 ho has an aftermarket can but stock pipe and it has had no effect on the engine or performance
