Adjusting port timing?

[carasdad]

Adjusting port timing? Looking at a kit it says comes with spacers for port timing. Never messed with spacers as I am used to the 'Just bolt on and go' Minarelli BBK's. So if the kit fits my scoot..why would I need spacers?.. How would I find out what the port timing changes are?.. Do I just keep adding or subtracting spacers till it runs best? I thought if the piston was near flush with the deck...about 1mm less...it was good...as that is how most "bolt n go' kits come. Here is a link to the 2 kits...would really like some input on if they are good...or which is best. Currently running a Hoca BBK..but the first 4 soft seizes due to oil pump failure have caught up with me. The kits say I need a bigger carb...jet and performance pipe...is it true..as I am already running a 70 BBK with a #90 jet and stock pipe. Here are the links.

If you installed a stroker crank you would need two base gaskets or a shim so the ports would line up

Does anybody know if these kits above would have better porting and more power than my Ebay Hoca clone?...

You cant say how many gaskets or MM hes going to need. Waaaaaaaaay too many variables. If you dont know much about porting and port timings dont start on a cylinder you pay big bucks for first. Start with a stock junk cylinder or 2 or 10.
Theres a book Ill link you to so I dont have to go into great length about this. I suggest you both read it, and anyone else who owns a 2 stroke that thinks they know a lot about them. It will open your eyes to a crazy world of case scavenging fun! This is only one of many books to read but it is the base to all 2 stroke knowledge.
