SBT Crank for 750 freestyle ski? Reliable?

[Hirschfelt]

As with any repair the mighty $ plays a big role. I need a new crank. I am thinking of SBT but do not trust/don't know their reliability with concerns to a freestyle engine. I am sure that the SBT cranks are great in stock setups. Any comments on SBT cranks are greatly appreciated.

My ski: 750 sx platform, Single 46mm SBN Mikuni, Vilder Flywheel, MRD girdled head, Factory limited pipe, blowsion angled reed spacers, R&D reeds cages and stuffers, wiseco prolites, dual cooling lines, 10/18 skat prop, blowsion freestyle pump cone. Getting port work done over the winter.

Drop a line on what I should do next to the engine.

look into a hotrods crank.

if it is an early sx with a small pin
you are SOL on hotrods:thumbsdown:

No crank like OEM, (however I do understand the $ factor)

I've got an SBT crank in my 800 X2. I'm running dual 44's, freestyle porting, factory pipe with a superjet limited chamber & ADA head w/175 psi. No issues to report

I've got one in my SXR with a Vilder Flywheel, wetpipe and a head.
It is a bigpin crank. So far, so good.:hail: I will probably sell it at the end of the season and buy another.

Are you buying another SBT?

I ended up going with a Hotrods crank after my SBT died

here is another thread discussing the two

regardless of what crank you choose, I was told to always use OEM seals

no probs with 2 750 small pin cranks from sbt. 3 seasons on both.
i have 4 years on a 1100zxi crank...so far so good.
very mild engines tho.
looked good when installed

no probs here running sbt cranks...

Sure. I'll just keep trading them in at the end of each season. It seems like a good well built crank...(I am not so sure about the bearings) Nobody will tell me where they get them or what brand they are. :thinking:
