[ Q ] Can anyone help? 99 cb400 super 4 proj. big 1 (nc31). Approx. every 3 weeks the main fuse melts / blows. Change it and all is fine. Now, intermittently, i lose power, no throttle response. Wait 5 minutes, and bike starts and runs again, maybe 1 km, maybe 10 days! Anyone with any ideas would be a great help.

[Q] planning to install yoshimura pipe to my Spec3. If ever do I need to change the carburator jettings ? & or do I have to resynchronize the air fuel mixture ? or just leave it as is ? I have K&N air filter installed.

[dragonforce]

after you install K&N air filter did you tune? install end can only no need to retune. install full system need to retune.

u might need to change ur jettings

actually air filter no need to tune, it also depends:lol:

 

end can if too lean also must tune, FS must rejet and tune

[joker888]

Bro, I did not tune the engine after installing the K&N & Yoshimura. Do I Need to ?

more experienced rider have answered your question...

i change end can i nv tune.. bike still running good. to me, changing to aftermarket air filter and fullsystem exhaust improves the air flow.. so by right need to tune. correct me if i am wrong. still newbie here also.

If its the green colour 30 amp fuse keeps blowing you are talking about..this si sign of overall electrical loading. Check see if you have too much thnigs installed that is using more in total current than the bike electrical should provide like HID headlite tapping direct, electrical horn without relay, extra lighting, wrong connection of so called "voltage stablizer", alarm system...etc. Better have this problem rectified fast..you can get electrical fire if not careful.

[Ah Pek]

haha mine also like tat lei. But mine is spec 3. Jia lat alr lor. Think mine really got prob. What could be the possible reason for this? anyone?

 

 

The possible caused may be internal friction...try X-1R added to your eo and see if there is any difference in results. I don't think it has anything to do with as of which version of Vtec.

[sukhairilmotorplus]

Hi all. Could anyone recommend me which is the best exhaust pipe for Super 4? And anyone intend to sell exhaust pipe and maybe power commander too? PM me if possible, thank you.

[MrIce]

which version of super4 you riding? what you consider as best exhaust pipe? price? performance? sound? looks?

[dbee]

ah pek thanks 4 reply...have nothing extra on bike at all....will check all connections to and from RR as u said....fuse seems to melt always on same side, negative connection, so start there i guess?

Consider trying out X-1R and my grounding...but no promises lah. Its the feedback I get from the guys. What about your sprocket size. Chain slack oso important.

hahah.. actually im planning to try ur special eo for my next eo change , gnding i was also planning to do also.. tell me how much u charges?? thank you

 

my chain and spocket ok leh, nv slack,also now need to change at the moment,still can run v long, how many teeth i nt v sure, nv go count..lol

[Niterider78]

I thought shld be the sprocket sizing thats why explain the slight speed difference?

Super 4 Spec 3. Concern with sound and performance, which pipe is the best?
