Hi all, after Cadwell ive decided to see if i can get abit more power from the old girl.
First up i bought an engine from CMSMJ1 (Cheers mate) which has had a little bit of headwork done to the heads, nothing major just a clean up etc.
I stripped these from the motor and once off i then inspected the valves etc and ive also removed the quietening gears from the cams for good measure.



Once happy i then started to remove the heads from my bike and here she is as she stands at the moment until my headgaskets etc arrive.





Also been looking into running a HRC style carb set-up so hopefully will be back together shortly to see what gains there are.

Ive found a set of what i belive to be RVF pistons if want to do them while your at it. A bit more work but how often are you gunna have the heads off?

[reverse cylinder jim]

Oooo
Do you know if they are a straight swap? Would they be ok with my vfr heads?

[Drunkn Munky]

Its a common upgrade for 30 engines, and 29's i think too.

I have a Carbon/Kevlar Ram-Air Airbox from A&R if you are interested in that mate?

[Drunkn Munky]

You still got that kev, could be tempted to have that back

[Smev]

Yes still got it - not had time to sort it all out - plus its probably too track focussed for me!!

Tonight i started my home brewed HRC carbs. Obviously this is not going to be a pukka set-up as everyone knows the original bellmouths, slides etc are very rare not to mention the price they command when they come up.
First up i bought a set of standard carbs as if this all goes tits i know i can always return to my originals. Once these were sourced i stripped them and cut down the standard bellmouth like so



Now the proper HRC stacks have a little flap that covers a little brass air tube and mine wont have this so i then tapped the tube to take a 6mm bolt. The bolt will have a 3mm (for starters) hole through the middle to restrict airflow. Once up and running i will bring sets of bolts with me to the dyno with various sized holes in them (2,2.5,3.5 etc) to see what size the bike runs best with. Obviously i tapped the holes with the carbs upside down so the brass swarf doesn't enter the carbs.



And then finally tonight i drilled the airbox tray.



More to come over the next few days.
