The 790cc Big Bore Kit includes a custom made, forged 9.5:1 piston with rings, wrist pin and circlips. A custom made multi-layer steel head gasket, OEM metal base gasket, tensioner gasket, and cam bolt lock plate and a ProCycle specific big bore cylinder sleeve. 

Built cylinders with 790 sleeves installed are usually in stock, but we must have your original cylinder sent to us as a 'core'. These cores allow us to keep up this program and it is nothing more than an exchange - we give you ours, you give us yours.

Designed, dyno proven and made in the USA, Hot Cams performance camshafts are one of the most economical, reliable and easy to install ways to add a 5-10% power gain to your bike.

Stage 1: These cams provide better low RPM torque, pulling power, and throttle response.

Stage 2: These cams will provide improved full throttle torque and horsepower starting at 4000 RPM and up.

• The Core Manual TorqDrive clutch delivers unprecedented performance, tuning and durability
• TorqDrive provides more disks in less space, allowing up to four additional friction disks over stock
• More frictions = more torque capacity, thus unlocking the full power of your engine without the need to add stiffer pressure plate springs
• Provides more consistent clutch lever feel and behavior
• Can be set up to maintain a stock, or lighter than stock, lever pull depending on engine tuning
• Rekluse sleeves eliminate basket wear and notching
• Proven in racing at the highest levels
• Made in the U.S.A.

The Rekluse EXP employs the same EXP assembly as their premier product; the difference is that it fits into your stock clutch assembly, saving you money! Now you can enjoy the benefits of Rekluse auto-clutch technology on your KLR.

An auto-clutch automatically feeds out the engagement of the clutch using centrifugal force. This allows you to start and stop without touching the clutch lever. The automatic feed is fully adjustable to suit the rider's needs while retaining full manual override with the clutch lever. This automatic feed delivers easier on/off throttle transitions, improved traction, better control, and more confidence.

RadiusX is a high performance centrifugal auto clutch combining our TorqDrive and EXP technologies. TorqDrive provides more clutch disks in less space, allowing for maximum performance within your bike’s existing clutch footprint. You retain full control of shifting and use of your clutch lever with no compromise in power delivery.

Features:

• Dead-on clutch engagement every time
• Take off and stop in gear without using clutch lever – no more stalls
• Experience maximum power delivery
• Confidently navigate traffic and slow speed conditions
• TorqDrive® clutch pack delivers higher torque capacity and increased power transfer
• Rekluse sleeves eliminate basket wear and notching
• Standard clutch lever function with full override
• No modification to stock components
• Shifting transmission remains unchanged (clutch lever use is recommended for shifting)

Our very own version of the popular thermostat bypass for the KLR. Gives faster warm up and more constant engine temperatures. Eliminates the wildly fluctuating engine temperature gauge. A more controlled and constant temperature is easier on your piston and cylinder and may prevent or reduce oil consumption. We use a 180 degree thermostat instead of the stock (too cold!) 160 degree unit. Warmer coolant temperature promotes better fuel vaporization and can increase fuel economy.

Our bypass system mounts the new thermostat in a small billet extension housing right where the stock thermostat is now. There is no bulky external housing to hang off the motor. The bypass hose tees in to the lower radiator hose using a length of quality high temperature silicone hose. It all makes for a clean simple installation.

Clymer manuals are the most user-friendly repair manuals. They are written for the do-it-yourself-er as well as the experienced mechanic by industry experts. Step-by-step instructions based on the complete disassembly of the machine. This manual in written to cover 90-94 models but nearly all of the information will apply to newer models also.
