What's the best parts to put on a 69727 non hemi 212cc with the rtc-9 head?
I ride a 2-speed auto motorized bike that currently tops out around 55mph. The engine currently has a 19mm slide carb, 4* adv timing, removed governor, removed fan and shroud and set up as a rope start, and now has a muffler but soon going to finish a new header with a performance straight thru kart muffler. A buddy of mine has turned his ungoverned 212 to almost 6k, and well the 2-speed on mine limits RPMS to around 5000 so I am ok on the safety issues.. And it's got around 1200mi on it, but I want to hit about 65mph at least.
The stock head gasket appears to be approx .010 and it has a dished piston. The ports are very smooth unlike the Flatheads I have owned, so I don't think I will be porting it...
Here's what I am planning
Billet rod and flywheel
Head shave
1.3 rockers
Springs.
Bigger slide carb
Now the questions;
How much can I safely shave the head without running into clearance issues, and reliability issues?
Will I need to get shorter pushrods after shaving the head?
What length rod should I get to use with the stock dished piston?
What length and weight springs?
What size crappy Chinese carb? Is 22mm ok..? Is 24mm better? As my intake is only 22mm...
