Greetings:

I've had a Ruima ministroke for about 1000 miles. Worked fine during that period.

I've heard that when it comes to reliability, stock honda is the best.

But if your stock crank has buggered up ends, I say go for the NOS Rumia. :2thumbs:

well i got i priced up stuffer inserts can be fitted to any crank including oem but the down side is $300nzd so that aint gonna happen id rather buy the malossi crank.But any way they reakon they can spin it up and balance it up better that it is (after they check it ) for $20 so ill that instead

That is pretty impressive they can do the insert job and balance it so well. They must weld the inserts on with TIG.

they talked about drilling holes either side of the pin the the inserts come thru .The insert has metal tabs on the ends that then get welded lots of work
