RK Tek Arctic Cat Laydown Engine (700cc to 800cc) Big Bore Conversion Kit
RK Tek has developed an outstanding option for your
Lay-down 700 engine. Rather than spend your hard earned $$ on the new
800 or 1000cc sled, you can upgrade your 700cc engine to a very powerful
800cc form and rival the 1000cc sleds.
This kit uses OEM Arctic Cat Pistons from the 800 Lay-down engine so reliability and functionality is completely maintained.
RK Tek has also developed a VERY unique porting
package for this over-bore. Couple this with our custom billet head and
you have a recipe for a very strong performer. We can also re-shape (NOT
SHAVE and change bore diameter) your existing OEM head to our dome
design. This allows for a total sleeper engine that will keep your
secret hidden from your buddies.
RK Tek has tested many pipe combinations with this
new kit. We have set-ups for most aftermarket pipes and have a very good
understanding of what is working and what is not.
OK, here comes the best part…. This kit can be run
WITHOUT an EFI control box (i.e. Boondocker Box)!! We have spent
countless hours developing this kit so it can be ran with the stock fuel
mapping. This is only the case when using the stock pipe and stock
silencer. If any aftermarket pipe/pipes or silencers are used, then a
fuel control is required. This kit runs on 91 octane PUMP GAS!
There are different levels of performance (HP) with
this kit. These different levels are largely dependent on the exhaust
Using the stock exhaust and no fuel control you can
expect a solid 160+HP from this kit. If you choose to run a single pipe
you can expect a solid 170+HP with TONS of low end grunt. If you choose
to use twin pipes 180+HP is easily achievable but the low end suffers
slightly in the 4000 to 5500 rpm band. No air-box mods are required for
The running rpm of this engine is 8000 to 8250 rpms.
OK, what is needed from you in order to do this kit?
RK Tek needs your cylinders only!
If you choose the OEM head re-shape vs. the Billet Head, then we also need your OEM head.
NOTE: PLEASE remove Exhaust Flange Studs
from each cylinder. Failure to remove these will result in more time to
complete the conversion and added charges.
We also need your exhaust valves ,just the
valve, itself, no cables or servo housings
ALSO: Please send in clean cylinders!
Porting thick, baked on carbon build up, is NASTY!!
PLEASE clean your cylinders and exhaust
ducts before sending in the cylinders...
