RK TEK drop-in kit
- Thread starter pinko
- Start date
I put a new RKT piston and Head kit in my 07 800R and have put on about 350 miles so far and LOVE it! The motor runs great so far.
I put the RKT pistons in my '06 X about 600 miles ago. Thought they were the greatest piston on the market until yesterday. I am not sure if the piston failed or something else went wrong, but i burned a hole through my clutch side piston. My preliminary guess is the post that keeps the ring from turning came out and scored the cylinder, causing a hot spot and a burn through

I have and I wouldnt go anyother way!
Do not go with it. I agree with the other guy go another way. I had nothing but problems.
We have a couple pairs in the garage that look the same way. Nothing but problems with us.

we havnt had to much snow here in washington this year. it has been a patience game waiting for good conditions to ride and determine weather the drop in kit was worth it. my 1st ride was good and i was impressed with the power gains. but every ride in between has been heavy snow or not enough snow to determine if i should click up or take pin weight out. i had not been taching above 7800 rpm. Finally yesterday,,,, the snow was good and light and the sun was out,,,, Rkt's kit rocks. i ended up clicking up to 5 which i've heard is to high,, you should be on 3 or 4. (so maybe i need to take pin weight out) needless to say, after clicking up my rpms came up to 8200. the sled came alive. what a huge difference. i felt the 18 plus horse gain and was left with an ear to ear grin. i was highmarking my buddies 09 dragon all day. thanks RKT!

I have an 05 800 and have ran both the drop in and the 827 and they both are very reliable and produced great gains. Perhaps some people can't follow simple instructions or maybe they had other issues.

Rk tek rips!
I have the drop in kit 800, followed step by step Kelsey's instructions for EVERYTHING and my sled rips! Ride mainly McCall and the Trinity Mtns up to 8,000 ft and sled pulls hard bottom to top.

mine runs great!
just gonna add to the list, have about 100 miles on his kit so far, i had an SPI pipe can and high altitude head, and switched back to stock pipe and skinz super Q can, it seems like a regular old 800 at around 7900, when you get it up to 8400.... WOW amazing sled. 14:1 compression domes by the way anywhere from 6500 to 9500 altitude.

yeah, i dont' know about that one. Stock sleds run just fine on pump gas. Thousands of people do it everyday.

IMO, the newer high performance two stroke engines are seeing so many failures is because of poor fuel quality. Just look at all the piston issues that ski-doo,cat,polaris are having. Ring loctator pins, skirts breaking, pistons with cracks in them, all with under 2000 miles. I have seen 550 fan motors run for 10,000 miles. Tell me why an 800 can not do that, it sure is not manufacturing issues. At 150hp you need better than 91 octane if you want it to live.

thank you, If only more people thought this way.
The big issue is ethanol. If you can get non ethanol then 92 is fine. If you cant then you better blend or ride like a pu$$y!

92 ? you can buy 92 octane at the pump? Up here in alaska the best you can get is 90. just because the pump says supreme does not mean it 92 octane. I wish I could buy 92 at the pump, All I am saying is pay attention to the octane label on the pump you are using, our pumps are 85 , 89 , 90.
I found a station who sell 92 without corn, he keeps it for the ATV,s Sleds ect in the town of white Salmon WA. near Adams,St Helens. Problem is fuel like this sits awhile, Ever wonder what it really is by the time I use it.Hmm, Its constantly degrading.i do wonder if a simple test kit is available to us?
One of our local fuel distributors carries non corn gas. And in WA supreme is 92. In Idaho and parts of wyoming they have 93 or 94 on pump. The difference between non ethanol and ethanol is so profound we manipulate our jetting on our offroad motorcycles by using one or the other. Going to ride at elevation, run ethanol. Going to run at sealevel run non ethanol. I have heard that it can change air fuel ratio by as much as 8%
