Well im still playing with this nee bbk barrel its 4mm longer than stock. Now i was thinking ok 4mm thats 2mm each way. Well no its all at top, so with my 4.4mm stroker crank the timing is way out more the point need to machine bottom of barrel. This is my question when i do this the timing stays the same as the piston drops below bottom of ports and short from hitting beak hight i used a degree wheel and did timeing but came up with 200 140 little high for street well i would ride but dont want or need cops on my ass all the time so if i lower barrel this will lower timing numbers or will thay stay the same as the crank hasnt changed or size of ports it need 1.7-1.8mm on paper but i have gaskets of diffrent thickness and thkught get 2mm off and have some ajustment instead of no gasket with no moving at all sorry long winded does this make sence. I did work out that 1.5mm would drop timing to 190 ex 130 would be happy with that. Motor should be near 20hp nice lol

Sorry brother, but I would gladly trade your great enthusiasm, and knowledge for some proper English grammar/spelling/writing lessons. I would give it for free! If you are dislexic, I can help! Seriously, if you are looking for informative responses, I believe you need a good bit of writing skills. It would help us...and we can better help you! Sorry for the harshness brother, but it is needed. |
