INDIAN BONNEVILLE

Restored 1948 INDIAN BONNEVILLE. If you like to stay out in front, hen this is the bike for you. Starts and runs strong. The following should answer most questions. Read and enjoy.The Indian Motorcycle Company produced and equipped the 1948 Bonneville Indian and 1948 standard Indian Chief with a 74 cu.in. motor.The Bonneville's 74 cu.in. engine is a factory performance upgrade over the standard Chief's 74 cu.in. Clearly, ne of the enhanced power factors of the Bonneville over the Standard Chief is measured in the Cams.Standard cams run out of power and speed fairly quickly because of their short lift, nd very low duration. The Indian Motorcycle Factory came out with the Bonneville cam and lifter set to increase power, nd RPM by increasing both the lift, nd duration. The factory had to change the lifter configuration to accommodate the change in cam design moving the rollers closer in toward the pivot shaft by nearly .085"; consequently, oving the timing by 10 degrees on the Bonneville lifters. The Bonneville's exhaust lifter retards cam timing by 10 degrees, nd the Bonneville's intake lifter will advance cam timing by 10 degrees when compared to the Standard lifters. Additionally, oving the rollers inward on the Bonneville lifters,changesthe rocker-arm ratio from .81:1 for Standard lifters to .86:1 for Bonneville lifters. Therefore, n a given cam, Bonneville lifter not only moves the opening, nd closing points by 10 degrees, t will also slightly increase valve lift compared to a Standard lifter. However, everal other factors distinguish the Bonneville's 74 cu.in. motor with superior performance, ower, nd faster top end speed over the standard Chief's 74 cu.in. motor:1. Magneto ignition. Two magneto Idler (timing) gears.
2. Larger Cam measurements -Lobe Height=1.575" (standard Chief=1.510")
Base Circle Diameter=1.100" (standard Chief=1.110").3. Cam Lifters and Followers are different measurements.
4. CylinderHead depth of Bonneville is different than the standard Chief. BonnevilleHeads-3/4" reach to spark plug (standard-1/2"). 5. Bonneville Kickstarter pedal-11 tooth (standard 10 tooth). Bonneville Kickstarter Gear-28 tooth (standard 32 tooth).
6. Bonneville Linkert Carburetor-Stamped M-BONN; has larger fuel feed nozzle, nd different size venturi-1 1/8"(Bonneville); 1 1/16"(Standard Indian Chief). Linkert Carburetor Stamped M-350, r M-351 will also work for the Bonneville.
7. Heavier Valve Springs.
8. Bonneville Cylinders (intake measurement different than standard Chief).
9. 1940-48 Bonneville pistons/rings are different.10. Higher compression.11. BM(Bonneville Magneto) stamped into case right after engine number.
Obviously, here are substantial internal motor part differences between the Bonneville's 74 cu.in. motor and the standard Chief's 74 cu.in. motor which accounts for the superior performance levels, ower, nd faster top end speed of the Bonneville over the standard Indian Chief 74 cu.in. Genuine Bonneville Indian Motorcycles are rare and hard to find.

Speedometer glass has a crack, aint around left gas tank is smudged from gas, nd left rear tank paint is chipped where it mounts to the frame; don't really notice it since it's under the seat. Left tank is sealed using Bill Hirsch Gas Tank Sealer. Kicker was rubbing on exhaust because the kick stud was bent; replaced with a NOS kick stud and the kicker clears the exhaust pipe now. I just never replaced (the exhaust pipe is a straight pipe I had custom made, nd is not the original, ut sounds and performs much better). No oil leaks and all the bugs have been worked out. Pictures were taken the day of this listing. Very busy right now and will try to respond to email as soon as possible. If you email the day of auction end you will not get a response. If the Bonneville doesn't sell I'll put it back in my house and place in the auction next year.
