I've heard some complaints that rear (main) bearing of the GXR28 wouldn't last long. Has this been an issue for you? How have you solved it? Do you know if there are any ceramic bearings around?

I've seen 1 at the track. The guy had broken the engine in properly and had about a quart of fuel through it and it acted like the pullstart was binding. He removed the head button and there was metal on top of the piston and when he pelled the backplate off, about 3/4 of the ball bearings were out of the rear main bearing.

Thanks guys

I spoke with Kyosho - there are few things to prevent the failure:
not to use too much air filter oil, proper maintenance and inspecting the parts condition on regular basis, changing the front bearing after first gallon and then every gallon or two

Yea Bro, I get you.

I learned about the bearings after about 5 gallons thru mine before I started checking the endplay at the flywheel. The bearings are not expensive & easy to change out. Just heat it with a gun & they pop out. Freeze the bearings first and they slide right in, easy.

Even a Worlds Edition Sirio Collari monster .21 comes with new bearings & rod in the wooden box for how much money?

Some guys blew motors at the Kyosho US Open at Kissimee too, but who knows the condition the engines were in for that big track. I’m sure a few guys running Sedan hurt their cars there too. I bet a lot of guys running Sedan went to this race track with brand new big money .12 engines.

If any engine is not 100% right, it can blow up no matter what it is.

Mike, I still have a nasty Picco/Collari G1XP-PRO all done up with the big slide carb, but for what, to have the same crazy problems you had at the track the other day.

Luv ya bro, I don't need those kinda problems

It’s all good, run a “GT Open” or get a “Super Stock” class going, but be pre-paired for the money war with these cars too! It would be cool to see these cars running close to the 70mph range on bigger tracks.

Call me when you get that LRP to beat Paul at Ronnie's

Jspeed,

Bvoltz and I have been talking about the many issues with the stock Kyosho engine as far as reliability. He has proposed that his series in Jackson, MS will include a "spec" engine. The engines of choice are the OS 21VG, Sportwerks .26 and Dynamite .26. (all have to be pullstart version). These engines are relatively inexpense (under $180). However, if a racer wants, they can still run the stock engine, so, a change is not mandatory. The pipe choice for the spec engines will probably be the Dynamite pipe (inexpensive as well). Give me your thoughts on this.

Well, I haven't had bearing issues (yet) but did blow up the original engine in the car. I did not know that 30% nitro was too high of a content for it (threw the rod through the piston, sleeve, and crankcase). Zootcapri and his buddy bailed me out with their slightly used engines. I had carb issues with the second engine and luckily had the carb from the destroyed engine to replace it. Others have had issues with the engine not holding carb settings, overheating (I have heard of temps over 325 degrees), and the listing is getting longer. Bvoltz decided to keep the rest of the rules the same, just lax them a bit for the engine concerns.

Kmichael is a good friend, but he’s not telling everyone about the Centax clutch, header and other mods he wants to introduce in the class. Are you Mike?

I suppose equal types of replacement engines could work when product availability concerns are an issue, replacement engines could use the factory muffler to even things more & keep costs down too.

If racers with the stock IGT .28 engines check & replace bearings on a regular basis, they can enjoy a car that can win races without the added expense of aftermarket engines, engine mounts or clutches; not to mention whatever else you'll need once you open Pandora's box

Jspeed,

For now, I will keep my car box stock and see what happens as Bvoltz' Bass Pro Series develops. Even as some will most likely convert theirs to his new "spec" engine(s), nothing makes up for lack of good driving skills and understanding the track and track conditions. I won the second race in his series with probably the second slowest IGT on the track. My driving skills made up for the lack of speed and overdriving by my competition (carrying too much speed into corners, drag racing down the backstretch, overshooting corners, etc).

Default Oh Jeff

Yes the centex is mine alone I was not sure about the stock shaft with the power but I could be wrong there,the stock header only fit that engine,but I'm using the stock muffer because it's a very good muffer,you on the other hand is trying your best to get kyosho to look at you but you doing it at other people expense,if you show a little knowledge and stop look the otherway maybe you get on the payroll,you said kyosho knows of the weak engine and their working on it so why should we keep changing the bearing and put time and money in it until its fixed,add up the time & money spent replacing bearing that often,once again I love my IGT car the engine is a weak link

Mike you got me all wrong.

Don't you go thru your engines after 1 to 2 galons of fuel?
I know I check my stuff every other club race and before every big race.

Dude, how many guys racing hard replace bearings & connecting rods after the break-in or before any big race?

Bearings cost like $30 dollars at Ronnie's, how much for a new engine, clutch, motor mounts......... People blow up the GXR engine when their bearings get sloopy. No sloppy bearings=no blown motors.

Like we always talk about, I have no problems so far with the stock IGT engine, you do, that's cool. We're racing a car that wasn't really intended for the abuse we give it. I think it does more than a good job for me.

Build your open car and have a good time with it.
