I ordered a titanium wrist pin for my 2 stroke 66cc engine..hopefully will stop some vibration on the Micargi

Anyone know what else it will need? Do I need to buy bushings? if so which?

You gonna need a new top end or maybe a whole new engine when that titanium wrist pin gets serious slop in a 100 miles or so........
 
MBR, can you please explain how you think titanium, which is stronger than steel, will wear out faster than a standard steel wrist pin?
No one has complained of such a miraculous event.

If it still vibrates too much then you can buy a Jaguar CDI and if its still too much then take the crank out and drill bigger balance holes in it. Click on my signature link to read about it.
 
Don't you need a machine to spin the crank to get it balanced right, kinda like balancing a tire to determine where it's out of balance?..............titanium wrist pin should outlast the motor considering all other metals are softer that surround it.
 
no spinning other than normal engine use.
the right size balance hole can be calculated. I think its around 12mm for the 66cc but its been awhile since I read my own info on it.

MBR, i am genuinely uninformed when it comes to the fitment and resulting wear differences between a stock standard wrist pin and a titanium wrist pin.
Can you please short cut my learning curve by explaining how the two different types of wrist pins wear as well as interact with their mating components?
 
saw a thread in which that pin failed (even while using the matching bushing)

titanium is stronger than steel, but much softer - you need a hardened surface for rollers to run on

I doubt this is any good for our motors.
 
I have never has a stock standard wrist pin fail, so have never had any need to look for an alternative option.

If titanium is softer than hardened steel needle rollers, it would be logical to assume that the titanium wrist pin would be the component that suffers an accelerated rate of wear, compared to a stock standard steel wrist pin, especially if you rev the rings out of the engine.

Really?
here are 2 miraculous pics of failed titanium wrist pins.
I have more pics as I know of at least 4 failures like these.

Titanium may be strong but the titanium wrist pins sold by juice are
obviously not very hard and wear badly.
the steel wrist pins are very hard and do not wear out.
