Follow those instructions and you'll have no problem. And thrust bearings blow, it's not related. You need to oil it after (or before) every run.
thanks jetmd your a ledgend

I like urethane(sp?) front and rear with rubber side. I have found, and read from others, the rubber kind of gums up the pulleys and the front and rear aren't THAT easy to change

anyone notice any wear on the pinion gears of your 4s?

i think that has lead to the gear stripping issue that came back at the end of my season.

Yes Its was mentioned awhile back that steel pinions are the go
they seem to last a lot longer especially on car park type tracks

I have a problem with my MTX4R leaning and richening over the course of the lap (always in the same place on the lap). This has happened with 2 different engines so I figure it must be something car related. Thinking it was G force related I have tried running the fuel line direct to the engine (between the air filter and heat sink) and around the air filter near the brake but neither seem to help. I'm starting to think my tank might have a small air leak. I'm also going to try running the pressure chamber.

Has anyone else has had this happen?

Also I've heard you can remove the regulator from under the fuel cap and this increases run time but I cant see how you get it out without taking the cap seal with you. Any advice?

I've never had this problem but have you checked your radio or servo. You think it is a lean bog but it could be your servo going back to neutral on that certain spot. If the bog does have something to do with tuning and airleaks just go and replace the whole tank.

it's not lean bog, it visibly leans and richens in the same spots lap after lap so it must be pressure related. Will try the new tank, I've always been a bit suspicious of it

Check your tweak on the car. you can also run the rear arms lower and that should give you a little bit more rear traction.

To convert a 4 to 4R you need new front uprights, front lower arms (or shave some off the original ones where the steering link mounts of new uprights will "meet" the lower arm) and rear upper link mount. That's all for handling & geometry change. Then you might want the cosmetic bits, new front spool/oneway and universals if you don't have them already.

you're better off using a thick grease for the thrust like the white grease that came with the kit. Light oil will run straight out the first time it spins. Other than lubing the thrust I do almost no maitenence on my R apart from keeping it clean, but it will depend on how dirty the track you race on gets
