General Discussion / Should i drill clutch basket holes
« on: October 31, 2019, 03:15:51 pm »
Hi all,
My clutch was a bit grabby when hot, so i removed it and cleaned and roughed up the friction plates and soaked them in 20w 50 oil. I also wanted to drill extra holes in the clutch basket to improve oil flow but discovered that it has no circulation holes. Perhaps only the later cb750's had pre-drilled holes from the factory? Has anyone else done the 'hondaman' suggested mod and drilled holes in their clutch basket to improve performance? I'm a bit reluctant to drill holes in an original part but will consider doing it if its a common modification. It's a late model sandcast and a Sunday runner re 10068**. Thanks.
