Honda cb750k2 engine rebuild
« on: November 19, 2013, 08:58:39 PM »
Hi guys
I'm currently rebuilding a basket case cb750k2 and have stripped the motor and am just doing the costings for the rebuild.  Have seen a 836 kit on ebay.  Could I use a big bore kit with std exhaust and airbox (as I want to keep std look). Only looking at bigbore kit as cost is lot cheaper than std pistons/rings - I'm not bothered about performance.
Any help would be appreciated.
Thanks
Phil

You should be able to do that but the carbs will probably need rejetting, back in 76ni put a 750 Morgo kit on a 650 pre unit triumph and had to reduce the size of the main jets

 ;) hi enjoy your rebuild  yes Honda parts been pricing themselves out of the market for a very long time 836 kit is probably the way to go its the best of the big bore kits without putting to much stress on the motor and things like jetting and k&n filters would be all internal mods anyway  8)

Anybody recommend jetting for 836 big bore kit with standard airbox (with the rcommended K&N filter in) and standard exhaust?
