Well, i bought a automatic 4 stroke bike about a month ago and i'm about ready to start modifications. I unhooked all the lights, horn, turn signals, and i'm ready for more!
I don't really have a whole lot of mechanical skill, but i think i have enough to get by on the 'easy' stuff. So, does anyone know of any free/easy/sorta easy mods to do? Iv'e been looking for stuff to do, but i'm not sure if it all applies to my specific bike. I have stripped all the plastic off, i found the idle screw, but after that i'm lost.
And something i should know, but since i don't i'll ask anyways..since my bike is an automatic, does that mean it is a CVT? What side of the bike is the CVT on usually? Iv'e heard of taking things off of the CVT, or sanding things in it..but i'm not sure what to do.
its called an X6 most of the time, nice bike. Which 4 stroke do you have? Step1 free mods: lighten clutch (they engage too low so this will raise it a bit), port the exhaust port (very restrictive on the E22 head if that is the one you have), advance your cam timing (you can buy XR50 specific books that will tell you how to achieve what you want by just advancing or retarding cam timing and we have had pretty good gains, actually excellent gains since it is free)
Step 2: call Genesis or one of the other advertisers and get a pipe and some gears from them and tell them what you want to achieve so they can guide you in the right direction.
Which 4 stroke do i have? Um....the 4 stroke kind? I'm not sure what else you mean by that. I took out alot of the packing from the exhaust today and noticed a 5mph (according to stock speed) gain in top end. I ordered a sprocket from Genesis, but other than that i'm not sure what else i can do with my limited mechanical expertise.

4 stroke...and it said it was a 70cc, but i'm not sure. :P
As for the gearbox..how do i know what kind it is?
And, for other news..i hit 36 on the speedo, go me!
I'm curious if i can replace my 2 pipes with one on my R6, has anyone tried this?
And, if anyone knows, do XR50 pipes fit our bikes, or will they need to be modded to fit?
I think Genesis Autoworks has put an FMF xr50 pipe on the x7 4T. I'm not sure it will fit on yours with the xr 50 head pipe. You may have to get you own head pipe bent to fit the exhaust where you want it.
How much louder did your bike get after removing the packing?
Your pipe is a big thing...our pipes include the labor that it takes to cut, bend, weld and finish our pipes...so you can expect a typical FMF that sells on ebay for 150 to go for 190 shipped from us. I think that is a fair price for a custom fitted pipe... I also have access to the same pipe that pbu sells for 180...i do not endorse it though...
My endorsement goes to the CHM 22mm Stainless pipe...it is the best 50 pipe on the market. You can't just throw any pipe that will fit on the bike...that is what the chinese did(so poorly). The avg 50 pipe is made for 50cc engine...the CHM, BBR, ProCircuit etc make pipes tuned for the big bores 70cc++... The one thing that you will notice is that none of the big names incorporate any expansion chamber in their designs...
Check out this review...
Pro-Circuit
This pipe comes on hard and fast. It closely mimics the power characteristics of a two-stroke. It does make instant power with the slightest crack of the throttle. It likes to be revved and handles short shifting really well. It has two optional end caps, one for low end at the cost of a little top end. The other for increased top end and loads of over-rev while sacrificing some low-end power. The end cap that comes already installed on the pipe is the "best all around" cap. It has impressive low end and rip your arms off mid to top. The construction is top notch and the pipe looks great.
I like how they incorporated the mounts for the stock heat guard on the header, that isn't something you see much on aftermarket headers for the CRF. The pipe is very light as well. This was the loudest exhaust in the test. It is a little pricey but it is the most versatile exhaust in the test, allowing you to shift the power curve to suit track or trail conditions. This is a great MX and even trails. It might be too responsive or brutal for some trail riders tastes, but if you ride aggressively, you will love this pipe - it likes to be pushed hard.
HMF Engineering
This is the best "value" pipe in the test. It is very similar to that of the White Brothers E-series Race system at a fraction of the cost. It is a definite "torque" pipe. This pipe loves to be short shifted. The low end seems even better than my WB Race pipe I was previously running. Mid range has a substantial boost, while top end seemed to be even with the WB Race pipe. Keep in mind this setup utilizes your stock header which means this is a very affordable exhaust upgrade, but will give you horsepower and torque gains across the board.
When short shifted, the bike is a wheelie monster with this pipe. The construction of this pipe is just as good as all the major brands. The pipe can be powder coated in various colors from the factory; it looks fantastic and is very durable. The pipe is a little heavy but it is really a non-issue. This pipe is only slightly louder than stock. The pipe is very similar in construction to the Pro-Circuit pipe. I would recommend this pipe for moderate MX and all trail riding. It produces a mild hit but for the most part is fairly smooth in power output. Aggressive MX riders may want a little more over-rev.
Big Gun Exhaust
This is the best looking pipe in the test. The Big Gun Race Series pipe consists of both the muffler and header. The header has a polished finish and the muffler has a brushed aluminum look to it. This is another "torque" pipe but with loads of power across the board even excellent over-rev. The low-end is very snappy, pulls hard into a very meaty mid range, and doesn't die off in top end - it just keeps pulling. This one of the fastest accelerating pipes in the test. You can short shift or rev it out, either way the bike doesn't bog down or fall flat on power.
This is an excellent all around pipe and is highly recommended for MX and all trail riding. The header is a little heavier than the competition but nothing drastic; you will still shed a few pounds over stock with this unit. The header does not have mounts to secure your header guard, but with the nice finish on it, I wouldn't want the guard there anyway. Construction is great with excellent attention to detail. This setup was a little louder than the HMF but not quite as loud as the Pro-Circuit. The Big Gun has a nice deep rumble to it.
CHM Exhaust
All I can say about this pipe is Wow! After trying this exhaust, I promptly put my WB Race pipe up for sale. This is the type of power that appeals to me. This is an absolute brutal pipe. It has a tremendous hit down low and a very impressive hit again in the mid range. The best way to describe the low to mid transition is like dropping a gear in your car and punching the accelerator hard, setting you back in your seat. This pipe has the most over-rev of any pipe I have ever experienced for the CRF with the exception of the Pro-Circuit pipe with the top end cap installed. This system is phenomenal from the crack of the throttle, 'til you're bouncing off the rev limiter.
The pipe is the king of fast acceleration and 10ft. tall rooster tails. It handles short shifts without effort; I can easily do 3rd gear MX starts with this pipe. Despite the neck snapping performance, it does have a few shortcomings. The header doesn't have mounts to use your header guard, and the system is not the lightest in the test, but also not the heaviest pipe out there. The construction is on par with most all of the pipes out there, the pipe has a nice kind of dark gun metal grey color to it. Some may like it some may not, just like the WB race pipe.
This pipe is up there with the Pro-Circuit with decibels. CHM offers a "decibel box" which lowers the dB rating to a quiet 96 dB for those in California or those who ride close to populated areas. This pipe would be outstanding for MX but might be a little intimidating for moderate trail riders. If you ride aggressively, you must try this pipe - it begs to be ridden hard.
Last Corner
All of these pipes are outstanding and I would be happy to be riding with any of them on my bike. You can't go wrong with any of these pipes.
For the value minded rider looking for the best bang for the buck, the HMF is the obvious choice. The price/performance combination, along with the durable and nice looking powder coated finish, makes this pipe a winner.
For the Aggressive MXer, trail rider, and horsepower freaks like me - the CHM takes the checkered flag.
For the moderate to aggressive MX and trail riders, and riders going for the best-looking system, the Big Gun blows 'em away.
For the rider looking for the lightest and most versatile pipe the Pro-Circuit takes it, it has more than enough power for beginners… and experts.

Ya, custom fitted pipes are nice. I saw a used Big Gun on ebay for 50 bucks, i figure if it costs me 50 bucks to get it fitted i'd still be saving money.
In other news, iv'e been seeing posts about lightening my clutch/flywheel and i'm interested in this mod. However, i'm not really sure what the clutch/flywheel look like. I ended up taking the cover off of something on the bike, but i'm not sure what it is, can anyone help me? Just for note, this is on the left side of the bike, in front of the chain.
that is not a clutch...that huge rotating mass can be eliminated by using an inner rotor kit. It is like removing 10 lbs directly off your rotating assembly...

Alright..how would one go upon getting an inner rotor kit, and how hard are those to install? And i guess my biggest question is where the heck is my clutch then?
