gregrob Posted March 30, 2008 Report Share Posted March 30, 2008 Here's the crank I'm looking at http://webforce.nwrain.net/founder/cascade...&search=4mm The one without the TZ bearing is 100 cheaper, are you guys running them right out of the box, or with the TZ bearing? Bear in mind I'm up here at 6-8K feet so I'll be making significantly less power than you dudes at sea level. Also it says "This crank is trued & welded inside and out". Is that something additional that cascade does, or is it just the standarh hot rods fare? Thanks a lot Quote Link to comment Share on other sites More sharing options...
dajogejr Posted March 30, 2008 Report Share Posted March 30, 2008 Welded inside and out is something they do. Standard 4 mil hot rods crank come with a weld, but they're shitty ones...and most builders will tell you they need to be rewelded. TZ bearings are the best. Here's the deal...and I'm letting the secret out of the bag. OEM Yamaha TZ bearings are no longer made, and they are becoming harder and harder to find. What a lot of people are doing are buyin NTN brand bearings that are The same design and style of the OEM yamaha bearings, cutting a groove in the outer race, and calling them TZ bearings. Even crankworks carries and sells NTN brand bearings but calls them TZ. So, IMO...is it worth it? yes...I've yet to see a TZ bearing fail. however, the maxload bearing that Jeff @ FAST carries is also a very, very nice bearing for quite a bit less money... You're paying for a quality part, and insurance...so...how much is that worth to you is the question. Quote Link to comment Share on other sites More sharing options...

Thanks a lot Greg give us a call as we have cranks (that are Rewelded for strength) on hand with your choice of bearings, couple of days closer to you, and alot cheaper.

gregrob Posted March 31, 2008 Author Report Share Posted March 31, 2008 Thanks for the input guys. I'll give you a call to discuss Jeff. Still figuring and making sure I'm gonna have the funds to go 4mil, but with me already getting porting, buying pistons, and bigger carbs, I figure this is the perfect time. Instead of doing everything twice, have the cyls setup for a 4mil, get 4mil pistons / domes, and be done with it. Quote Link to comment Share on other sites More sharing options...

Thinking ahead usually puts you ahead (I think I might coin that phrase...LOL) A stroker crank and good porting to match will make a BIG difference, one you'll be happy with.

gregrob Posted March 31, 2008 Author Report Share Posted March 31, 2008 Thanks man. Don't I need 795 series pistons with a 4mm long rod? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted March 31, 2008 Report Share Posted March 31, 2008 Yes. 795 series for the long rod setup. Quote Link to comment Share on other sites More sharing options...
gregrob Posted March 31, 2008 Author Report Share Posted March 31, 2008 Cool. What kind of numbers you think it would throw down on a dyno with an "aggressive" dune port? It's always hard for me to guess being up here over a mile high would be 33pwks more than likely, with the 4mil and other mods in my sig Quote Link to comment Share on other sites More sharing options...

dajogejr Posted April 1, 2008 Report Share Posted April 1, 2008 Very possible, but the TZ on my 10 mil with stock cut gears hasn't had an issue... Quote Link to comment Share on other sites More sharing options...
