02 GSXR Engine Boging.

[blaqgixxer]

Fellas need a lil help on some trouble shooting. We just replaced the engine on my patna 750, his origianl engine blew. The second engine he got a bad deal on ( had a crack an was leakin). Anyway the problem since the second and now 3rd engine has been installed is the engine has been boging out or has a lose of power. It rides fine untill you try an open the throttle on it has like a pause before the power kicks in. I'm thinking something to do with the fuel system. Have anyone had this type of problem?

Guess no one has any input or ever dealt with this type of situation.?
I thought it mite have been a fuel problem, clean fuel filter but say thing is happening.

[mr600]

are all the sensors plugged back up right? none missing or not plugged in?

[blaqgixxer]

Yeah we checked over the plugs same thing with the 2nd engine. Now I"m thinking it could be the fuel pump since the filter has been cleaned & still running the same.

[mr600]

that could be it also

man, having the same problem, and i was told that it may be my valve clearance, or my cams may not be set right. getting it fixed over the weekend, will let you know how it works out.

Wonder if it could be dirty injectors. Any rust in fuel tank at all even just very light surface rust? Plus this ethanal gas sucks especially for storage has it sat a while? And maybe check around secondarys make sure nothing gummed up around them (if it has secondarys) and just for heck of it pull a spark plug see if it got alot of carbon on it if it does replace them all. Shoot could be alot of things best of luck.....

ram air hooked up?, had zx 6 did that if a line came off the ram air

TPS?

TPS is a good guess. I would check there. Try to get hold of a fuel pressure gauge and make sure that is within specs too. Do you have a service manual? I'm sure you do but if not... GET ONE! They are life savers.

One of the guys I ride with is having the same problem, 01 GSXR 600, will let you know if we figure anything out this weekend.

sounds to mee like you may need to do a sync on your carbs/throttle bodies wichever you have....(pretty sure old katana is not fuel injected) usually if it is the tps you will have a code stored in the ecu so you can do whatever magic suzuki requires for you to bring it up to find out...
