Thanks, thats the sort of site I've been trying to find. I've dropped Phil an e-mail. Al

Bump... Somebody out there must know something... Al

Reded, I would, but Banshee's and hot ones are thin on the ground here in New Zealand where I live, so people who know then in detail are few and far between... Al

Reded, You said "I think most people with high HP go with max load bearings on all but the outer clutch side (some even use them there). I went with a TZ on it just for extra insurance." !) Which TZ bearing did you use where? 2) When you say max load bearings, are you talking C3 clearance? Is there a speciifc bearing # or place that these are coming from? 3) Are the Banshee outer main bearings left and right using the same inner diameter and is this 32mm? Sorry, I'm new to Banshee cranks and trying to get up to speed. The application is my TZ350F motor which spends a lot of time in the 10 -11k rpm band and is making 77-78 bhp at the contact patch. the existing outer mains are bullet proof, but with going to a cut down Banshee crank (trim the end to end width a touch) they go into the TZ (TZ cranks are getting fragile and hard to find). Only problem is the original TZ outer main bearing inner dia is wrong for the Banshee outer shafts, which means we have to use Banshee mains . I don't mind spending extra money to get a good bearing to save my carcass! I just can't find any information.... I guess ultimately, a high load C3 clearance, phenolic cage ball bearing , with groove, would work fit my needs! That should hopefully give you a little more info TIA Al

Hi team, I'm looking into main bearings for Banshee's and have a couple of questions. 1) I see a lot of references to Banshee cranks fitted with TZ main bearings. As a 54mm stroke TZ has 25mm ID outer main bearings (where the Banshee's have a 32mm shaft dia), I assume that the bearings fitted are only the inner mains which have a 32mm ID, same as a Banhsee crank, or is it a bearing from a later model 50mm stroke TZ250? 2) What mains are preferred for the outers, on the big HP, or big capacity (eg bored and / or stroker) motors. Are there a "performance" option available or are people still just fitting the stock ball outer mains? Thanks in advance for any information Alistair
