Scott, why the 09 head but an 08 cam?
Hey Snowflake,
The 09R head is considered to be the best ported and the 08R cam gives the best all round power. Hot cams work down low or up high but the 08R is meant to give improvements at both ends.

I figured whilst the engine was getting rebuilt I would strip her down and service/ replace all bearings, seals, sliders, guides etc and put the comp loom in. I have a lot of work ahead of me!

It’s very satisfying rebuilding from nothing , keep us updated mate
Remember only 7 weeks :ohmy:

Until you try and destroy it again
A lot of work to get through there Scott :whistle:
A great rebuild though & I know it will be better than new when your done with itI slung the Honda up and got into it this arvo. I gave the frame a good scrub, did the headset, fitted new bars, ball raced throttle, grips and polished the frame just for Menace

I put in some more hours this week and am looking good for the Noosa deadline. I cleaned up and greased the swing arm and linkage. I stripped down the carby and gave it a good clean. Re-lubed the shock bearings and cleaned up some more of the plastics. I also polished my Yoshi pipe to a mirror finish and put fresh alloy logo plates on it.
