Welcome and thanks for sharing Tom.
Do you think that a 32mm carb would do a better job over the 28 with the 150 kit on??
Because looking at the Honda CRF150R specs,it has almost the same spec as the 150 kit(bore & stroke wise) but the crf is utilising a 32mm pumper carb.I'm not sure about valve sizing and port flow for the crf,though.
Cheers.
Merry Christmas!

actually Steven, I only saw your bike's internals before the upgrade...I think only Jan saw the big bore and all... = i don't know jack s*!t
all i do is "assuming"
Dave, the piston that Steven is using is from a local manufacturer(Modenas) from a model named Jaguh(refer http://www.modenas.com.my )...
it had a longer stroke, so what they did (i assume
)was decked the piston's top to match the stock stroke while keeping the same piston bore...
a few lines of my assumptions
Regards.

The stroke remains the same but the bore is diffrent (i can't recall how many mm). Total is 147cc as per caculated, the water jacket cylinder wall had been reconstruct. Well have to get back my book to see what had been mod! i have forgotten most of them!

I trust you all had a good holiday season, and that all are safe and well. To answer jbthumper regarding carb size, in my case the 28mm flatslide was 'Plug & Play' on my bike as it came from that expensive German company. To be fair, it was quite a comprehensive kit, with a bored manifold etc., etc..
I have not taken it to a larger size as at 28mm it works so much better than the stock carb (which is a terrible carb), and so well with the other mods, that it is not worth messing with it any further. I had had a flatslide on one of my previous Harleys and it was a crisp performer just like its 28mm little brother.
Incidentally, fitting this carb into place is not easy, and requires some patience. There is barely enough space to fit it in.
All the best for the new year!

)
