sbk info

hello fellow xbhpians..im from bangalore and im new here.
guys this is my 1 st post and this might be little repetitive over here but i must know this before i choose my 1st sbk.
after a lot of thinking and convincing my dream to own a sbk would come true.. but im really really confused. let me explain my dilemma
as i mentioned earlier this would be my 1st sbk, so should i think of going for a 2nd hand 600cc? but is there really a legal used 600cc bike in india?
or should i go for a 2nd hand 1000cc? my personal favourite is suzuki gsx1000r [ the 2008 white bike... kick ass ]... but since suzuki launched gixxer only 6 months back, is there any 2nd hand showroom bought gixxer available? i hear that all other gixxer 1000s imported are grey, is it true?
so now my only option is r1 for a 2nd hand which was released here bout 2007 i guess... i was a huge fan of the r1 but i heard r1 has serious heating problems and few ppl who ve riden it say tat it has a more aggressive posture and hence difficult on ur back and wrists.. this has made me negative on the r1....

now guys plz plz help me choose.. my budget is a modest 7-8L , preferably 08 or 09 models IF A 2ND HAND... wat say guys

lol Ironman, why don't you tell him yourself He's your friend too

Well you know he's more of a show off and less of a person who has passion for his machine so all this tech would sound like Russian to him! LOL!

[ZeNashB]

Wrong timing or HT leads gone kaput or his spark plugs' porcelain/ceramic is cracked. He better check if the pugs are firing at the plug's end and not with the plug cap removed. Or something must be wrong with the distributor motor.

Something must be wrong with the distributor motor otherwise. Or it might be loss of compression because you said the bike lags if he twists the throttle suddenly. But the last reason mentioned is very much unlikely unless the valves have been fiddled with.

[ZeNashB]

Yeah, its constantly heating up now. The temperature stays between 98C and 102C. Its definitely gotta be a problem with a wrong firing order which is causing the cylinders to be overloaded, hence the heating.

Also, he took it out for another ride to determine what else is wrong, and discovered some extra problems now.. The throttle doesn't respond if he suddenly twists it, but responds fine if he does so gradually. The bike shudders a little at 2k-3k rpms then becomes fine again. It no longer revs beyond the 7k-8k mark either.

They are only due to the wrong timing?

@ OF: Why would the bike get hot if there is some problem with spark plugs? like caps interchanged, or the others like all cylinders not working ?

I guess it could be because the cylinders that are working will be overloaded and start overheating.
I had a similar problem when one of the cylinders on my bike stopped working/misfiring. This caused the CatCon overheat and it started glowing orange.

[ROCKRZ]

as OF rightly said, it could be because of the wrong firing sequence of engine with the leads interconnected at the wrong plug. this happened with my car once and hence can corelate this..

Also if i may add old fox sir, could be the injectors n throttle body that require cleaning? someone here had a similar goof up with gixxer, throttle body and injector cleaning solved the issue!

Could be so Naval, but I am working on the premise that dirty throttle bodies and clogged injectors don't happen overnight. Even clogging of injectors gives plenty of prior warning. The fact that mere changing of the plugs messed up the bike points to that area. Also that the bike overheats within a short time.

[navalds]

Hmm, very valid points you've made since he had got the plugs changed the same day. The mechanic might have not done his job properly. I'll ask him to check the plugs/HT leads tomorrow.

Its an awesome bike, before this happened. I'm sure it can be fixed Thanks

The symptoms apparently indicate that all cylinders are not firing. Reasons could be 1) loose spark-plug cap/s 2) faulty HT leads (the wires connecting the spark-plug and the ignition coils and 3) wrong firing order i.e the spark plug wires have been connected in the wrong order. Cylinder #1 gets plug cap #1, #2 gets plug cap no. 2 and so on. Check the bike's service/shop manual for correct assembly of plug wires or look up on some 954 forums on the net.

Okie guys, my friend has a small problem with his '02 Honda CBR954RR Fireblade. He got all the 4 spark plugs changed because two of the old ones had died and his cylinders weren't working at their optimum. He's put in a brand new battery after charging. When he started it, the bike was showing serious lag when he revved. He twisted the throttle and it wouldn't rev beyond the 3k RPM mark. Occasionally, it jumped to the right rev indication then lagged again. Stuttering and shivering all the time, he managed to move it for a km but it totally stopped after that. He filled the fuel tank thinking it was a low fuel problem but it persisted.

Whenever he twisted the throttle, even completely to its limit, it would just rev to 3k, not more... making weird 'bur bur bur' sounds. Soon after that, the battery showed the ''low'' indicator and in idling, th temperature suddenly rose to 107 and the bike shut down. He pushed it back into the garage and that's where it is now. What could be the issue?

Dont think it would be a problem..
