  1. I have an 03 yz450 and an 04 GSXR 1000. I started with a GSXR750, which put roughly 130 hp on the ground(never had it dynoed). It didnt take long to get comfortable with it and before i could even put some go fast goodies on it, it was stolen. I decided to go ahead and get the 1k and I am glad I did. I must admit I was a bit intimidated by the 1K which is why i bought the 750 to begin with. I have owned a CR500, CR250, YZ450, and a RM125. The difference in a 600 and 1k's acceleration seems to be about equivelant to the CR500 and RM125. The big bike pulls like a nuclear frieght train all the way to 186. It will honestly float the front wheel under hard acceleration at 140 mph. It is strange, but after a couple of months I felt like I wanted more power. I mean the bike has incredible torque for a 4, similiar to the big thumpers but way more brutal. I can actually ride the 1k easier and faster than the 750 because you dont have to rev it so high and the powerband is perfectly linear. my brother who had never ridden a street bike, after 5 minutes was pulling standup wheelies at over 100mph on the 1000. The power is insane but you have control over it. its simple, dont twist the throttle so much and you will be fine, in fact you will probably kick yourself if you buy a 600. I have ridden 600's from all 4 of the big japanese manufacturers and I have to say they are impressive machines but the intense, almost intoxicating feeling of acceleration is just not there like the 1k's or the 750 even. If you have the fundamentals of riding a bike, you can ride a 1k or even a zx14 for that matter. you just have to get accustom to how they turn, you lean them, push on the bars to turn. I would go with a bigger bike and take it easy. I feel like I am less likely to mess up on the 1k because it seems more user friendly and I have much more respect for it. whatever you decide, be careful, more people die on 600s than liter bikes. It is usually the cager(person driving a car or truck) that causes the accident. There are so many more factors and dangers when riding on the rode, and also very very very easy to get your self in a lot of trouble. I can hit 102 in 1st gear. I believe I read in Sportrider that the 04 gsxr1000s accelerated to 100 mph in less than 4 seconds in ideal conditions with the right rider on it.

    Gear Shifter Stuck

    I pulled the entire right side off, including the clutch and the case as well. I found where the "fork" that shifts the gears had slid off so i put it back on. that fixed the gearing problem, i reasembled the engine, filled with water and oil again and kicked it 25 or 30 times. i blipped the throttle a couple times and all it did was backfire. while in gear, the bike still will not roll at all. i pulled the clutch basket and inspected it as well as the plates and measured them according to the manual and they are well within spec. i am at a loss as to why the clutch refuses to work but moreso why the bike will not fire up. i am getting spark and fuel as well. i plan to check the timing as well as the valve clearance again as well.

    Gear Shifter Stuck

    a few weeks ago i purchased an 03 yz450f. i got it for what i thought was a steal. The guy said he thought it needed a head gasket because there was water in the oil(milky) I offered him $1800 for it and we had a deal. i brought it home, decided to kick it to see if it would kick thru a stroke and the thing fired right up. of course i shut it off immediately knowing the oil was bad. I did some research on forums mostly on ThumperTalk and decided i should replace the waterpump seal and bearing and if needed the shaft(which by the way looked perfect so i didnt replace it). I dissasembled the engine, i didnt split the cases but i pulled out the clutch pack to see if it was worn because as i put the bike in gear when i was running, the clutch was not fully engaging, it was creeping forward. After taking head and cylinder off, it appeared the piston and rod and valves were almost new, harldy any carbon buildup and the cylinder was smooth as glass. i poured about 5 or 6 quarts of oil thru the engine and drained as much of the white oil out as possible and replaced the water pump bearing and seals. after spening quite some time(im new to four strokes) getting the cylinder, head and cams back in and the timing correct, i put everything back to together, checked to insure the valve clearance was in spec(all 5 were) and kicked on it for almost 20 minutes. all i got was back firing, i could smell gas and i checked the plug to see if it was firing and it was but i replaced it anyway. it still didnt crank. i didnt do anything to the carb while it was off, so i dont see how that could be the culprit. i decided to give it a break until the next day so i leaned it up against my weight bench while it was in neutral and it apparently put to much pressure on the shifter because it is in gear now and i cannot get it to go into neutral or any other gear. also when i pull in the clutch it doesnt seem to engage. it is the same as if the clutch were not pulled in. I was hoping someone would have some input into the not cranking and the locked up shifter. I have a feeling that the cams may be off a tooth and it is difficult to decipher where the I is to make sure it is at tdc. also i was wondering if the the clutch could be the culrpit for the shifting problem. I believe it could be the shifting fork, i hope not, i dont want to split the case. Anyone had any similiar probs?
