Hey guys. For those of you who dont remember, right before I picked up the bike I was asking around about some reported problems from the owner at the time. Well now that I own the bike, and have put about 5 hundred miles on it, I have made some of my own discoveries and have some things to run by you guys. 1st off, the bike:
1997 GSXR 600
Mods: D&D slip on, factory pro Jet-kit, K&N air filter
The kid I bought it froms next door nieghbor worked on bikes at a yamaha shop I think it was. He did the jet kit. I have all the parts of the kit that arent being used. From what I can tell the FP kits are much more in depth then other kits? Looks like I could do almost a rebuild with all the parts I got in that kit. Ive jetted car carbs with kits that didnt have so much. I was given with the bike a 1 down front sprocket, 5 up rear, and a Yosh header. All of these things were on the bike at one time, but not any more(he couldnt handle the sprockets, header was taken off cuz he said with out getting re-jetted it actually hurt things, and he was going to sell it).
The problems and questions:
1) Are all the SRADs kinda noisey in the engine? My roomate has a lil Harley sportster 883, and I used to crack on him for having more engine noise then a honda car(the factoy "Valve tap" that we say is the hampster). Bought the SRAD and I might be more noisey then him. I test road 3 before I got this one, and they were all louder then my old YZF.
2) The original problem I was told about but with some better insight for help.
Here is the original link with the way he explained it to me, and the help offered then. http://gsxr.com/showthread.php?t=26747
What I see happening, isnt quite the same, and has led me in many different areas of thinking what can be wrong. I notice the bike breaking up alot more at different RPM ranges but not so much up top. I notice ALOT of the breaking up at around 6k rpms when not using much throttle. It starts to break up, a shift up or down and or more gas gets rid of it. Hold it steady tho and it sounds like a poorly tuned turbo car(I should know my roomate has a poorly tuned 91 300zx TT, lol). Very rarely do I have any problem with breaking up in the HIGH RPMs. I MOS DEF thought for a lil while that there was a bad TPS. Again basing my judgement off of a car problem tho, same car as mentioned above with a bad TPS acted the same way. When holding steady throttle lower Rs, and lower speeds, it kinds jerks and lunges as if I was waivering with the throttle and sounds like it too. Then last night and today I have some rattle noises coming from what I think is the gas tank???
Jetted poorly? Jetted good, but not good for the colder weather? Fuel pump? TPS? All of the above? lol.
Lastly where is a good source of info on the SRADs? General info, like normal operating temps, idle RPMs, stuff like that. Thanks guys and sorry for the length of the post. Just trying to give you as much info as I can.
