Title: 24000 km service 15 tooth sprocket
Post by: enzo on December 09, 2019, 10:09:59 AM
big service for my bike today, i had abit of a list of thing to change :denso iridium spark plugs, oil filter, rocker gasket, 15 t sprocket , a new hole plug chrome, the usual motul 10/40 5100, clean the k&N air filter with the kit and oil it, check cylinder balance, check the ecu with some gadget see if everything is in order, valve clearance, coolant refill. Anyway enough to keep my usual mechanic busy nearly 3 hours! he work hard and carefully, took the bike for a ride and came back saying that that 15t sprocket is ready good! After trying it my self i have to say that, yes , it s actually great! the bike isn't sluggish as i worried about, the gw s torque is good enough, but finely i can make real acceleration with out running out of rpm, i dont have to change gear that often in traffic and it picks up speed much much better. Who ever isnt sure about making the change.... stop waiting and do it. I live in heavily populated area with alot of traffic and still i find the 15t is finely liberating my bike. blablabla but sure if your inazuma is black or red you will never experience the blueness speed  :008:

Hello!

Sorry to dig up this thread, but I was interested in what is the procedure for checking "cylinder balance"?

My zuma has developed a nasty vibration and gritty feel to the motor  :012: and I'm trying to troubleshoot.

Any ideas welcome!

Ya. I used to balance the carbs on my Goldwing. I'm not so sure it makes a diff with a 250 twin, and besides, we're fool injected. The only thing I can think is it must be refering to the valves being perfectly spec'd.

I have now changed to a 15T sprocket as well. Previously I had tried one out but swopped back to 14T, I felt it impacted on acceleration. Some trial and error on my part but, like everyone else  seems to feel, I have now concluded it does make the bike better! Just for info original chain and sprockets lasted about 10k miles.

I'm glad to hear your sprocket references. It's especially good to know you went back and forth and conclude the sprocket change is good. I would do that too, I think.

I mean, you've got the sprockets, why NOT experiment? No cost to do it yourself. I have to remember to order that thingy.

If they made it, I'd like to know if another tooth (16) difference would work. Seems like maybe they don't or they don''t fit. I'm alright with lower rpm.
