Moose Race Fit Radiator Hose Kit
Keep yourself COOL with a set of Moto Hoses. Moto Hoses are what you need to handle the heat that your bike is putting out whether you're pushing it to the limit or just stuck in slow city traffic.
Each Kit Contains:
DRC is one of the leading manufacturers of silicone hose kits for motorcycles.
Genuine Honda replacement thermostat
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.
The complete Thermo Control package - Our in-house designed Thermostat Bypass kit, a set of Custom Silicone Hoses and a Hi-Pressure Radiator Cap. All combined to help your KLR cooling system be at the top of its game. The Thermostat Bypass kit includes a thermostat with a higher temperature rating that will keep the motor more in its happy spot.
The Silicone hoses are stronger than the stock rubber units and will better resist cracking and leaking.

This 3rd gear set is made for us by Nova Racing Transmissions in England to replace the fragile stock third gear set. These folks build complete transmissions for World Superbike teams among others, so we believe them to be highly qualified to build this set of replacement gears.
These gears are made from a high quality special alloy steel and then heat treated and superfinished. The mainshaft drive gear and the countershaft driven gear are sold only as a set.
The long awaited Wide Ratio Transmission from Nova Racing. Now you can have your trail gearing without giving up your highway gearing.
Both sets are lower than stock in 1st and 2nd gear and taller than stock on 3rd thru 5th gears. Not only will Nova give you better gear ratios but the high quality components will shift smoother and engage more solidly. The tables below show each gear ratio and the original OEM ratios for comparison.
To help put the ratio changes into perspective switching from the OEM 15T to a 14T sprocket lowers the gearing by 7.1% in all gears. Switching from a 15T to a 16T raises the gearing by 6.6% in all gears.
| Stock | Gearing | Ratio |
| 1st | 12/29 | 2.42:1 |
| 2nd | 16/26 | 1.63:1 |
| 3rd | 21/26 | 1.24:1 |
| 4th | 21/21 | 1.00:1 |
| 5th | 23/19 | 0.83:1 |
The "A" gear set has an 8% wider gear ratio spread than stock.
| "A" Set | Gearing | Ratio | From OEM |

| 2nd | 16/27 | 1.69:1 | -3.7% |
| 3rd | 19/23 | 1.21:1 | 2.3% |
| 4th | 22/21 | 0.95:1 | 4.8% |
| 5th | 24/19 | 0.79:1 | 4.3% |

Kit includes feeler gauges and wrench.
A 'wrench style' tool to turn the 'square top' tappet screws. The wrench does a better job of holding the adjuster screw still while tightening the locknut. Slim and flat, this tool is easy to carry in a tool pack.
Set includes:
Two feeler gauges on a single tool. Angled to make checking the clearances easier.
Stock valve clearances are .004" intake and .005" exhaust (.10mm int. and .13mm exh.)
Getting ready to adjust your valves? Here is a set of feeler gauges to make the job a little easier. One tool has .002" & .003" gauges the other has .004" & .005" gauges. Yamaha lists the specs as follows: .002"-.004" Intake and .004"-.006" Exhaust, clearance measured when engine is cold.
A set of feeler gauges so you can adjust the valves on your Yamaha. Yamaha says that when the bike is cold, the Intake should be between .002" and .004" and the Exhaust should be between .006" and .007".
This set includes one gauge with a .004" on one end and a .005" on the other for your intake side and another with a .006" and .008" for the exhaust side.
Two feeler gauges with angled ends to make checking the clearances easier. Stock valve clearances are .004" intake and .008" exhaust (.10mm in. and .20mm exh.)
Cylinder head upgrade. Features CNC machined port shapes, larger high performance valve seats and custom made valves. Valve sizes are increased from the tiny stock 33mm intake & 28mm exhaust to 36mm intake & 32mm exhaust. This is not a radical modification. These bigger valves bring the valve sizes up to what would normally be found on other brands of 650 singles.
Big Valve Heads are sold only on an exchange basis. We need your stock head for the next batch of modified heads.
We strongly recommend checking valve to piston clearance when installing oversized valves.
