CockneyRick Posted September 27, 2021 Posted September 27, 2021 Out of curiosity i popped the lid off the 1230EF? engine i acquired, & i was looking at cams & noticed the front had a worm drive on it. Now i know that is similar to the cams in my GS1000, but seeing as the Efe doesn't run a front engine tacho drive, i'm wondering what cams they could be? Quote
Gixer1460 Posted September 27, 2021 Posted September 27, 2021 Possibly early GSX11 - ET etc. maybe a regrind? 1075 and 1135 cams are interchangable. Quote
CockneyRick Posted September 27, 2021 Author Posted September 27, 2021 Cheers, apparently a guy called Con Skett owned the engine before, but tried to contact him but no reply Quote

I do actually have a set of Stage 2 Kent cams here, despite the bigbore but they may be a bit much for road do you think? Quote
Joseph Posted September 27, 2021 Posted September 27, 2021 (edited) Yes that will just be a GSX1100 exh. cam that will have been fitted to your EFE head Edited September 27, 2021 by Joseph Quote

A bigger engine will work nicer with 'bigger' cams - all can be calmed down with sub optimal head / carbs. You can have the biggest cams in the world but without the airflow they won't perform anywhere near as good as stockers! Quote
CockneyRick Posted September 27, 2021 Author Posted September 27, 2021 So the St2 cams, 1230 bore & i have a set of CV36s or even CV34s? Quote
Gixer1460 Posted September 27, 2021 Posted September 27, 2021 I'm not giving tuning advice, but i'd give it a go! It's not rocket science to swap them out if you don't like! The 34's may give a better 'pull' 1 Quote
Joseph Posted September 27, 2021 Posted September 27, 2021 The general thought is that smaller carbs improve low down torque at the expense of HP higher up, whereas large carbs will provide higher RPM HP at the expense of low down torque 2 Quote
