Hey guys

Any issues yet?

also plz make sure to mention if u balance it or not!!

theres been a few issues with them, not pretty on some expensive builds.

What kind of issues?

 

[BATCH450r]

i believe on the 06+ stock cylinders the cranks crack them, correct me if im wrong, but i remember something like that, or maybe it was the DASA cyl.

and some say it vibrates more and u have to get the crank and pisotn balanced at crankworks.

Spend a little more money and send your stock crank and a piston to crank works and it will be alot better choice

Not balanced and No problems thus far (knock on wood). I like the torque my bike has now too, good setup

 

[trx500r]

only problem i have had with mine is the great power out put and the increased roost from all of the torque. I did have mine balanced and it feels so close to stock its crazy but it turns up quicker bc of the shorter rod

If you have actual personal knowledge of an engine that failed as a direct result of the use of a HR HD or +3 crank,then buy all means post it up....but....please refrain from using blanket statements or using third party heresay regarding this subject.
I recently started a similar thread and there were quite a few responses and to my knowledge...there have not been any reports of durability issues of failures due to the HR cranks.
The only failures I am aware of are the ones that combined a big bore/stroker combo....and it was the cylinders that failed...not the crankshaft.That is not to suggest the cylinders are at fault...in some instances...builder error or other parts failure could be a factor.

What he said.
I have not yet seen the crank as the issue.
I am still going strong on mine with the Athena 98mm jug. So far, so good.
But I don't have huge hours on it yet either.
I did not balance, but I wish I would have. It will just add longevity to the whole build.
