Hey everyone! This is my second katana, i had 600 last year that was 2001 model which i sold and bought 2004 newer version 600 as well. My previous kat was all tip top and running perfectly, this one has a couple of issues
.
The first issue i had was my carb was overflowing, flooding my Exhaust pipes. I opened up the carbs, cleaned them a bit around float area and few other places ( i didn't dismantle them that's a big mistake i know )... I returned them and bike was running back ''normal'' same as previously.
There are other issues that are happening constantly:
- Jumpy idle, it's really unstable and jumping 50-100-200 rpm on idle, it never runs in place
- Until it get's hot enough and i go trough 6000 rpm couple of times, it's really bogging down when i open throttle, like it needs to break trough that point and from then on it's going normally
- RPM's are slowly dropping down from 2000-2500 rpm when i release the throttle, not really slowly but rather slow
- With previous exhaust and from yesterday with new MIVV replica which is free flow exhaust, it's popping a lot on decel, i open it wide open and release the throttle and it's popping a lot, i suppose too rich mixture
- Rubber inlet boots are bit cracked on the places where screws go into the engine, from what i roughly saw they are good from the inside.
- Rubber caps that go over vacuum inlets are cracked ( carb sync points), i dont know if i should change them
Stock brass caps are still on AF screws, my petcock is working properly from what i tested out but i will repair it as soon as i can.
I have old pic's from the carbs when i opened them last weekend i can post them here.
My idea is to get the bike running properly , its got 23000 miles on it and it's US version ( imported to my country in Europe), last kat had arround 50.000 miles and was running like new
so the idea is to get this all sorted out.
Oh few things that i didn't mention, new air filter is added from ti HiFlo , should be same as the stock one.
