Monty Thank you for your time on this.

I was on your site looking for a new Mill

I seen you said the plus 21-4C "TEAM" over the Btta or the BTTs or BTT.

Why Sir?

I would like to have a smooth OS vspec type feel like back in the day when the vspec first came out.

I love to hear you input on this sir.

Thanx Dibbs

Just ask guys who have used both;)

A few of us around here are finding that the re12 powerband is slightly more powerful than the 9901. Sounds kinda strange given that the re12 is supposed to be a copy, but we've found some differences.

I run a stock P5XLT with the RE12 pipe in buggy and I love it. Great combo.

17011 front bearing

ok , i have had this happen to guys a couple times over the last couple of years so here is a tip and warning

when installing the 17011 front bearing in your engine , do not use a flat faced bearing installation tool unless you have some sort of spacer to let install tool surface hit the outer race and not the inner race as the bearings inner race protrudes by .3mm . this will do irrepairable damage to the front bearing and render it useless

it is the best bearing on the market bar none and when properly installed will yield the best protection you can get from a front bearing


hope this helps

I have always heated the block and froze the bearing so it just slides right in. and then use the crank before everything cools to make sure its all lined up properly. Is that still an ok old school method?

Re: installation of front bearing
 

Houston. Good day.

Soo. When installing a front bearing, is it not advisable to use a hudy bearing removal/installtion tool?? Isn't this and some others the type of tool that basically presses on the center portion of the bearing.

Interesting...

Also, what about the concept of heating the case and freezing the bearing?

Thanks

Pull everything out of the motor including pinch bolt. Heat the block in the oven or use a heat gun, this expands the metal. Once the block gets a little over 300* the front bearing will pop our with a slight push from behind. Freezeing your new bearing makes it slightly smaller (contracts the metal). Get the block back up to a little over 300* and using the crank I push the front bearing back in from the front. Quick pull the crank and put it back in the motor the correct way and spin it. Doing this lines up the front and rear bearing. Be careful not to dislodge the rear bearing or you'll have to re-seat it too. I have pulled and seated a lot of bearings that way and never had problem. including the OS .50 Hyper I ran in my Trex 600 at high head speed for gallons and gallons on end, I lost count around 18 or 19 gallons :eek:.

Bearing replacement
 

I have replaces several bearings over years. I'm by no way saying I'm an expert and like to hear the different ways to do something.

If the fit is tight, then I warm the block up. I slowly press the bearing in and when it gets to almost bottom, I go even slower. I can feel the bearing reaching bottom and that is when I slow down even more. I can see over pressing the bearings can put excessive pressure on the balls and the internal races. Who wants to blow up an engine by such an act. I don't.

Hudy bearing tool FTW!

Thats what I do, but lots of people say using the tool is better.

.

According to Internetslang.com, FTW means
