CT Raptor 660R 686cc High Output Motor Package......$1355.00
This is a very solid, reliable, and well developed package which puts you solidly in the 60 horsepower range.
Kit includes: CT head porting, 5 angle radius Race valve job, Web cam, cylinder bore for fitment of a JE hi performance 11/1 or 12/1 piston kit, valve spring kit with titanium retainers, valve stem seals, head cleaning, assembly and disassembly of valves from head, valve grinding, and top-end gasket set. The 11/1 piston is best for 91 octane pump gas and the 12/1 requires 100 octane gas. This can be attained by mixing 108-112 race gas 50/50 with 91 octane pump gas. We strongly recommend the use of our CT pipe kit to gain the full potential of this package. This kit price is for you shipping us your top-end only. If you would like to ship us your complete motor, add $250.00 for R&R of top-end.

CT Raptor 660 Pipe Kit
CT has been working very hard on the Yamaha Raptor 660R. We're proud to announce our exhaust system has the largest horsepower increase we've ever seen from a bolt-on exhaust. This kit consists of our CT pipe and disc type spark arrestor, Pro Design Pro Flow air filter, and jet kit. We picked up a minimum of 7 horsepower at 3000 RPM and 32 horsepower at 8500 RPM. This is a must have kit for the Raptor. Stock horsepower is just over 33 horsepower and were hitting almost 50 horsepower with this kit. We did all of our testing on a California model. The end result is the same. 49 state models have slightly more horsepower stock (rumored to be around 37).
Noise: The disc type spark arrestor system allows you to tune the noise level. Our system tuned for peak horsepower running all 16 discs puts out a throaty sounding 102dB. This is not acceptable for many riding areas. With the disc type system, you can simply remove discs to get to the range you need. At 6 discs, you would be in the 93dB range. You will lose some horsepower as you cut the noise. Our pipe will still make the most power at any dB as compared with any other aftermarket pipe at the same dB level.

| LB-021 | Raptor 660R Head Porting
CT Racing has done significant amounts of flow bench and dyno testing to offer you the best port layout for your application. We highly recommend getting a valve job at the same time the head is being ported. Our CNC valve job ties in with the port work to offer extremely effective flow numbers. |

| LB-023BV |
Raptor 660R 5 Angle Radius Race Valve Job for +1mm Intake & Exhaust Valves The 5 angle radius Race valve job significantly raises the flow characteristics at low valve lift and definitely shows a horsepower increase throughout the useable power curve. The 5 angle valve job really shines on big valves as the seat diameter is opened up all the way into the aluminum casting, blending to the port work. Adding +1mm valves to a modified engine package helps the mid to top-end horsepower. Most aftermarket hi compression pistons are clearanced for +1mm valves. Seats not included. |

This axle is a recreational level axle that is twice the strength of the stock axle. It's a cost effective choice when reliability is a prime concern. |

| AX-DB-20-1142SP | Dura Blue Eliminator 2+2 Extended Axle
The Eliminator axle used for all forms of racing and high performance applications. Many of the models come with the patented Posi•Lock system which removes threaded sections from the flexing area of the shaft (a source of crack generation). |
$400.50 |
![]() |
| AX-DB-20-1142EX | Dura Blue Eliminator X-33 Pin Drive Axle with
Cast Hubs
The X-33 axle uses the same superior material and heat treating as the Eliminator. The unique difference is in the design of the wheel hub mounting area. Standard design ATV axles neck down to about 1" in diameter. A splined wheel hub slides onto the axle shaft and is retained with a hex nut. As all ATVer's know, hubs loosen frequently. The X-33 changes all that. The wheel hub is clamped solid and driven by a pin on a 1-3/8" diameter shaft. This axle is rifled to reduce weight near the rotational axis of the ATV. The X-33 allows for 16 different wheel offset alternatives. |
