This wasn't in the budget but I bought it a couple of months ago anyway lol just scanned in my as ported cylinder port map the only data not correct is the angles of the transfers I can't get the software to let me input the correct angles lol .looks like I can raise the transfers a bit more than the mx250 porting and a touch more widening of the exhaust and then I just need the expansion chamber to do the trickery to get my targets I want to get the rpm up another 500rpm from this at least but it's a good starting point .will work on bolting the barrel and head onto my flowbench and plug the base with a plug of policarb and do some checking of the scavenging pattern and flow balance of all the transfers
If you go the route of new carby and have some choices, try the style with the so called Power Jet at the rear. The big advantage is when the main is lean the low pressure will suck fuel from where every it can.
I only just fitted the keihin pwk35 in place of the 28mm stock makuni .I would probably go something with high and low speed adjustment screws for some fun but 35mm should get me a fair way.
Had the barrel and head flowing some serious air today had to pull to motors out of my flowbench as it was easier than adapting the barrel into the 4 inch hole lol.found one main transfer is loud as and turbulent but not all the time you can poke your finger in the hole and it goes away for a few seconds then returns I can see a peice of alloy in the flow path that's causing it just need to try get a tool in to get rid of it.smoked the transfers and watched the swirl few little mods to do
Found some blue in a can its brake caliper paint not quite dark enough I don't think but it looks smart after a quick spray to test the color .ran out of 400 grit paper so will get a couple of sheets give it a quick rub mask it all up and blast it on and top it off with some clear
My Chinese footpeg upgrade arrived seen sturdy as all hell for so cheap.had to edit the springs a little to make them suit but huge difference in foot room for my size 10+ foot and feels so much nicer with them level instead of all worn and drooping so your foot wants to slide off on every bump lol. now I just need to cut the pivots off rotate the spline section down to level and weld the pivots back on as the factory height is too high for my lanky legs all up I think it's around 40mm lower than where they are now
Finally after being lost in the post for over a month my hydraulic clutch conversion arrived .had to fit the handlebar end to see what it fitted like can't fit the rest cause the cylinder is off about to get honed for new rings as you can see the tank is also sanded back for one last coat wasn't happy with the finish
