Default 128 build problems.




Hi everyone,I've been a bit stupid. I have a 2020 fxlrs, I've been buying parts to upgrade to stage 3 for a while done cam chest etc last thing was the big bore kit. I've purchased on ebay which said it was for my bike. pn 910-0733 which I believe is for touring models, everything seemed fine until the rear barrels bottom 2 fins sit on tappet block cover. (too late to return kit now).so I'm thinking low profile tappet block covers or machine out a few mm of the fins. would this work or is there other problems that I will encounter?I know I should have double checked part numbers but I'm at where im at.any help/advise/info would be greatly appreciated, thanks in advance.

If that's the case, then I would have to guess that its front and rear cylinders.

The installation instructions:

state the following:

NOTE: The cylinders are NOT identical and must be installed in the correct location. The rear cylinder has additional clearance machining in the pushrod area. The front cylinder does not.
