test fitting cylinder for clearance (making sure it's not sitting on the layover gaket of the CT black.

actually had to dremel clearance for good fit.

even with dremel very tight fit.

test fit everything making sure gaskets don't interfere with eachother. very tight fit with CT black and polini corsa. once gaskets looked good i tightened the base of the CT black (10ft lb.) also the stock head bolts wouldn't fit in the corsa head?? 2nd time this happend to me. had to switch to stu...

going to document my biuld.

SYM DD50 motor w/ Polini Corsa

stock intake ports

somewhat matched upper half of boost port to corsa boost port (i turned block upsidedown and used a small file)

hows this corsa comming along??

what carb and jetting???

current setup still getting hot. ported block (to match corsa. intake and boost done) malossi stuffed crank new bearings new seals (used tool to put in to make sure they are in the right spot) polini corsa V8 typhoon exhaust 7.9 gears kelli pulley w/sef ramp 7.5g weights 28oko 48p 148m compression 1...

is the polini bore brand new an ride wide open trottle? yeah i installed it new. the first 6-7 tanks were at 1/8 - 1/4 throttle trying to find the right jets and checking for leaks. the temps go high when i just cruzing at 30-35mph. so there was a lot or re-jet and test around the block. after the ...

i wish running too cool was my problem

Did you do a leakdown with the temp gauge attached? How hot is your bike getting? What is your needle at? Did you port match the boost? 150 is a huge jet size for a ministroker. You need to learn how to do a proper plug chop. You should be in the 132-138 main jet range with a oko 28. Get rid of the...

The color of the porcelain mostly indicates if the heat range of the plug is correct. In order to "read" the plug for proper air fuel ratio you need to look down where the metal meets the porcelain there should be a soot ring and jet by the thickness of the soot ring. Personally plug chop...

checked EVERYTHING... (crank seals, cylinder head/ base gasket, manifold) no air leaks... Bike gets to 430 deg. FULL WOT plug chop > perfect cardboard brown. 28oko 55pilot 142main Too much compression will make it run hot. what is the compression at now? compression was at 135. added head gasket an...

lowered the compression to 118 (3 head gaskets) still running hot... no leaks everything checked. i have the same setup with the ministroke and the 50mm taiwan. the piston is perfecly flush with the bottom of the exhaust port on BDC. pretty sure its the 50mm made for the ministroke cause i just used...

so 135 too high for pump gas. thats probablly why i'm heating up. I have the corsa on with 1 extra head gasket (addition to the O-ring) and i get about 135ish compression. you think if i drop compression to 120 or below i should take car of the heat problem? is it OK to use multiple head gaskets (2-...

anyone have trouble with leaking gaskets on their CT chrome or black manifold?

if so what did you use to get a good seal on the manifold?
