Kibblewhite valves?

[Kickaha]

long time since i've had a BM bike engine on the bench

I can fix that for you

Pretty strong talk from a man who's got a full season of chair racing planned.....

Last 3 Bm's were a R100S kevin McCleary had pulled apart for the owner - and never put back, a late cammer for Adrian walker - and an Isetta motor...
Actually the Isetta is a big bored 250, whoopdedo...

Go hard, I'm still going to beat you on a stock one.
I fixed my concerns about over revving stock parts, I smashed my tachometer to pieces in a massive crash & now I wouldn't have a clue what it revs to.

Most likely, I'd better watch those warm up laps at Taupo as the tacho is the newest part on mine.

You could have hammered it back together and won the championship last year, there was no plastic cup only a certificate.

These "modern" racers seem to think they're all the rage.....apparently.

I might send the ECU off to VW for flashing ( that's "modern" talk for staking, and smacking with a mallet.

I still got one that said third, & I wrote my bike off three meetings before the end of the season.

I have Kibblewhite valves etc in a few bikes including a Norton 750 head that Jim Comstock reworked.
Maybe the question is are you going to simply replace the valves or use the Kibblewhite guides also that normally come in two material options to suit the valves and the stem coating.
The longer wearing of the two (guides) need some specialised tooling as far as setting the clearance, there might be something relating to that on the Access Norton site.
You would be hard pressed to find a better valve given their reasonable cost.

Was hoping to just get the K liner replaced so as not to disturb the original guide. I didn't realise the valves/guides were a set as such. Access Norton sure is a good source of engineering information.
