Time To Get The Baja Race Ready!

[misterleon]

if you feel comfortable with your ability to do this I would 100% recommend. Torque is the enemy anyway

 

[szaki75]

yes, with Dremel. as i can recall it was the 3mm round-end milling bit.
as i can recall, 0.016in (0,4mm) drop equates to approximately 2-4 degrees MORE in exhaust timing.. and i cut 0,6mm from the piston.

0,6mm would give you about 5deg more exh duration...

 

[MonsterAir]

What was your process for measuring? Did you take a little off then check timing and go back or do you have a better tool than a digital caliper?

 

[szaki75]

it was just a digital caliper.
i measured the initial distance from the bottom of skirt till the top of the chamfered part and noted down. then marked the area with a dark marker on the top i intended to cut and started cutting it... little by little and measuring frequently to see the progress.
i’d cut 0,5mm, put it together and check with degree wheel where i got, and continue with the cutting if needed.
watch out not to cut wider than the exh port window.
i used flexible shaft on Dremel and moved from right to left... and hold the cutter firmly.

porting is so much more than this, and i just did it 2x... so i don’t feel myself comfortable in giving advices here.. ? (though i got good results)

Take some fine grit paper and smooth it out a bit. Looks good otherwise.

Can anyone point me in the direction of a front disc brake kit that uses pads. All the ones I'm finding (mechanical style) are all aluminum on disc which from my experience don't last like the padded kits. I don't want to go hydraulic.

I think I got a bad receiver?

After slapping a new (temporary) throttle servo in today my killerbee stopped recognizing signal loss when I shut off transmitter. I went down the list and checked settings on KB, re bind, swapped servos and battery, even swapped another KB in there. Just won't buzz or go into failsafe when I disconnect the transmitter but the servos go back to center. Or at least the throttle/brake does.

All functions working on another receiver I have. Chitty as that one has some knicks in the antenna. YeY! more parts to put on order!

Bummer mate

Was out chasing my parents dog around their yard today and seems like the servo saver didn't wanna wait for it's replacement to come Monday. A relatively soft slide into a fence and bam no steering.

Dam Im surprised it was that easy to break for you. My 10+ yr old one took a few cartwheels to break. What y got coming for a replacement?

Turtle racing hd. Ordered it from ddm last week.

Very nice, got the tr in my Baja too, you won't be disappointed ??

 

[MonsterAir]

Got myself a little care package from DDM today.



Next thing I need before I dive into electronics is Springs! She sits a little too level for where I plan on running.

 

[MonsterAir]

Got the tr saver installed and polished up the rods it sits on. I'm glad the stock saver broke. It belongs in the trash!

A lot smoother.


Took her out for a spin and am happy so far.



I think maybe I have a bad gas tank or cap. Seeing fuel under the cap after running. Hmm, do I get the kraken fuel system?

 

[Z.hb71]

Seems like a bad cap seal. Just buy a new cap they're like 5 bucks

 

[MonsterAir]

Na their like $12.50! lol.... Luckily the Snappy RC fuel kit came with a rubber seal for the cap! It's the least they could do after having me tare up my fingers trying to get their freakin tubes and grommet in. I purchased w/ FullForce brass fittings which are a waste of time and money There really isn't enough benefit to justify the hassle of installing them.

 

[Z.hb71]

yeah the snappy kit is poop, PITA to install and leaks like a mofo

Leaks? Where at the grommet? I didn't feel the upper barbs were snug enough so I slipped tubing over them. Did you do this?

I did that?? swapped out the breather to a cheap chain saw one way breather and no more leaks??

yes its setup just fine, the vent itself leaks . ive redone it like 5x tiems and leaked every time, a mx grade vent is the way to go. they are like 5 bucks
