| Case Modification |
|
Boring your cases to accept your new big bore kit can be quite the challenge for the inexperienced and should only be attempted by trained personnel with proper equipment. Various suppliers make jigs that can vastly simplify the process for the do-it-yourself mechanic. If you must tackle it yourself, please invest in one of these.
Once the cases have been bored to the appropriate dimensions you will need to plug the center bolt location. This can be accomplished using a 1/8” stainless steel pipe plug. You will no longer be using a center bolt after the case and cylinders are installed. After a great deal of testing on both low and high horsepower applications, we have found the center bolt to be a non-factor in overall case structural integrity and not using it removes the possibility of it inadvertently turning and causing cylinder bezel cracks. Once the case halves are sealed and the cylinders are torqued to proper specifications the center case location will seal properly. If you have any questions about the process please do not hesitate to call for further instructions.
Supplied below are the case bore dimensions for the respective models:
1999-Present Twin Cam 88 A-B:
4.250" Big Bore Cylinders (114" 124" 131") – 4.410" x 1.500"
4.125" Big Bore Cylinders (107") – 4.310" x 1.500"
98" Bolt-On Big Bore Kit – No case boring necessary!
XL/Buell Tube Frame – Buell XB (Including Blast and Ulysses):
3.875" Big Bore Cylinders (90" Kit) – 4.010" x 1.500"
3.8125" Big Bore Cylinders (87" Kit) – 4.010" x 1.500"
1250cc Big Bore Cylinders (76" Kit) – No case boring necessary!
Evolution Big Twin:
3.875" Big Bore Cylinders (100" Kit) – 4.010" x 1.500"
3.8125" Big Bore Cylinders (97" Kit) – 4.010" x 1.500"
3.563" Big Bore Cylinders (85" Kit) – No case boring necessary!
PLEASE NOTE: If you or the builder continues to run the center bolt and the cylinder suffers damage due to the bolt, this will not be a warrantable issue. |
