Status: offline 		wow that would completely piss me off if mine was pos and my friends was better. is there by any chance kyosho would replace these engines if somthing catastrophic like this would be happening to their engines? i mean come on its kinda on the same line as the overheating xbox 360's such a pain in the ass. I think i will be calling kyosho tomorrow about this, and see if there is anything that they will do

Status: offline 		Nick - I feel your pain brother. I was one of the unlucky ones with bad one. I know another guy, Allenthen who started this thread and his runs great. I too did the whole replacing the fuel and presure lines. Tank lid gasket was ok. Tuning and tuning and tuning. I rebuilt the carb, still had problems. I also sealed around the carb neck with High Temperature RTV. It got better but still ran erratic. That engine cost me a few races and decent finishes as well. It ran awesome for break in and the first gallon. Then was all down hill from there. How does yours idle? I had big troubles trying to keep it idleing without stalling. Keep in mind that your engine will heat up when it is just sitting there. The concept of cooling for these engines is for air to flow over/through the cooling head. No movement, no air flow. Do a few high speed passes and see what your temp is? Another thing is after running a few tanks, what does it look like around your flywheel area? Is it really wet? Do you have a greasy stripe of fuel/grim on the body? Even though bearings are "designed" to leak.....................very little (this is how they get their lubrication) there is a time when its too much. I came to the conclusion that my front bearing was leaking excessively because the stripe on my body was excessive, there was fuel all over the place and a build up of track dirt and fuel around the flywheel/chassis area. So being the race nut that I am, I couldnt just sit back and fight this anymore. I bit the bullet and bought an OS .21 V-SPEC. I have no regrets about it. F A S T! You might want to change the bearings on the engine? Go to AVID bearing. They have a great selection of bearing, great quality, and excellent prices too. If you change the bearings, and with everything else you did and still have problems, then your only alternative is to get a new power plant. If this doesnt cure your problem, then I am at a loss. Let us know how you make out.

Status: offline 		At the risk of getting told to 'butt out' of the thread, these kyosho buggies are built down to a price. Corners are cut otherwise you might as well by an MP777 WC. I had an earlier version of this buggy (the sport 2) which had a few too many flaws for my liking. It seems Kyosho have addressed some problems with the US sport but there are still issues.
My sport had a GX .21 (the .28 is just a sleeved up version). Although woefully underpowered it was quite reliable. If you search back some old threads you will see the .21 suffered exactly the same problems. Some were good, some bad.
When you look at competative kyosho buggies in race listings you will see none run kyosho engines. These are just added to get you going and are at the bottom of the food chain when it comes to RTR engines.
With a few well researched upgrades the buggy CAN be ok, but if you wanted a complete, quality RTR package out of the box you should have done a little more research.
Don't let it get you down though, most on here (including me) made similar mistakes when getting into the hobby, so you are not alone.

Status: offline 		you know what i beleve this buggy would be a really good one if they just addressed a few issues. one of course being the engine. if they just built it a little better and sealed a few things this thing would scream and would give a few higher end vechiles like the losi eight or ofna a run ofr its money.

anyways i finally got my tempature situation down. i resealed everything on the back caseing and carb and now, idle is running aroun 170 and running around 190-210 depending on speed. when you do the water test on the head it dosent boil at all, un less it was running hard. it sounds different and reacts different now too and its got a good pop to it right off the line. if the seal holds i have a really good engine now. i just hope i dont have to do too much more too it.

I guess one thing to always remember is you get what you pay for. Not many pro's running Losi's, run Losi engines, etc....but yes the GXR is IMO a piece of junk. Other than that I have no probs at all with the US series Inferno's, remembering the 7.5 is a world champion. There are not many complete, quality RTR packages out of the box (Losi excluded, far more $$$). I wouldn't call buying an Inferno a mistake either, just a learning curve.

Status: offline 		There is no denying that it can be upgraded, almost endlessly, but for the money, it is a good base, I'm not saying the best, but good. The very first upgrade should be the diffs as advised earlier in this thread, from there, blow your mind.

Status: offline 		I have no regrets getting this buggy at all. There was no way in .........................I was going to spend around $1000 bucks for a high end buggy as my first buggy. This is my first one and I did not know if I would like it. Better to be stuck with a $375 buggy than a $1000 buggy right Johnny? Yes this is an entry level buggy. I agree 100%. But again this is my entry into the 1/8th scale buggy class. Yes the engine is a weak point on this buggy. It seems to be hit or miss with the engine. Unfortunately for me it was a miss.
Aside from the new OS engine $245 I have spent approximately 25 bucks on diff lube and extra spider gears for the diffs, and about 30 bucks on shock springs and sway bars. I will not include tires and rims because I would have bought them with any other buggy. So I am way way below the price of what some of the guys I race with have spent. One guy has a $1200+ Losi 8. I know because I asked him. One thing you have to remember about the racing portion of this hobby is 80%? of it is the driver. Im not saying Im a pro, no where near that but I am decent. You should see the looks on the faces of the $1200 buggy racers when they see what has finished ahead of them. I have raced this buggyy competetively 5 times in the 07 season. Not much right? It took a long time for me to get used to it. Much different than the Monster Truck I used to race. Plus the fist 4 times was with a flooky Kyosho engine. The last race of the season, my 5th time racing it, and first time with the OS, I finished 4th in the A-Main. I beat out a few LOSI 8's, A Kyosho 777, and a Hyper 8.5. All with my mildy upgraded US Sports Ready Set. So yes this buggy can compete. It has great potential. I have no regrets about buying it and have no plans to purchase something better. You guys will be the first to know when I get that A-Main victory. Its only a matter of time.

Status: offline 		There are no two ways about it the MP7.5 was a world beater just a few years ago, and while the world moves on the world of buggies doesn't move so quick that the old 7.5 isn't competative. Sure you can finish a race with it. I was very happy with how mine handled.
It just broke in too many places. I had shattered wheels and wing, bent chassis as it didn't come with a front torque rod. These things i could forgive, even the crappy AM radio and underpowered (but luckily in my case reliable) engine. What i found the biggest insult was the 2 planetary gears per diff, plastic spur and no engine mounts. I just couldn't get my head round that.
I just found it easier to sell and buy a different buggy. Cost me about an extra $100 and was very happy after that.
I wasn't trying to upset anyone, just trying to explain why the kyosho comes with a crappy engine
I'm sure the US sport has some of these issues addressed anyway, so it is not so much of a problem.
My advice to anyone who has one and likes it is just replace any parts that break with kanai 2 or 3 parts and you will have a very nice buggy in the end.

But how do I then get my images in here?

Status: offline 		hey again guys. just got back from the local track . put about 6 tanks through that gxr. 28 running quite smoothily now. just need to tweak the tune a bit. has great acceleration but top speed sucks balls. good thing it was only a pratice night. around all the corners i had no trouble getting around guys but when it came to out back straight away it just would not get up to speed realy well. ah well at lease it not getting hot any more. sits around 220 to 230 now. i think im gonna still get an OS though and keep the stock as a back up or somthing.
