2005 Honda CBR 600 RR Questions & Answers
I have a 2005 Honda CBR600RR the bike was running fine yesterday, now it starts losing power in the higher gears and around 13k RPMS usually can get it to go over 150-160 no problem but now it maxes a
Running her a little hard are we... fun huh....I miss that fun!!
This is a drastic drop in performance... this sounds serious..
1. Did you change gas stations..(swag)
2. Has the engine started sounding different in free rev? Does it till idle smoothly? It will rev out with very little compression.. but not run well!!
..If you are not a good mechanic.. take it to someone that knows how to run a proper compression check...or..
3. Get a compression gauge... check all cylinders.. with the throttle wide open they should pump up around 140psi..+.... if you are getting low #'s. 100psi... or vast differences between cylinders (120psi in one and 160 in another - you have found the issue).. Top end power requires compression...
A drop in compression could be piston/ring related or valve related. This requires a teardown for closer inspection.
4. Check you air intake system .. make sure some critter hasn't snuck in there.. check your air filter - replace or clean it.
5. Once you have done the two items above.. repost with the results and details.
I have a 05 honda cbr 600rr, im looking at changing the chain and sproket. what size and lenth and all that stuff do i need to get
1st. -
NEVER change sprockets without changing the chain..and vice-versa!! - they need to be replaces as a set...they wear our almost equally.. ie - a worn out chain will wear out new sprockets... A new chain will get stretched out by worn sprockets real quick!
Its east to tell what you have...
- OEM sprocket size: 16/43 - 2.68 ratio.
1. Count the teeth on your front sprocket.
2. Count the teeth on your rear sprocket.
Compare yours with stock(OEM)..
Now, if your sprockets match the stock sizes - count the number of links in your chain...(count the inner links).
If the sprockets are different sizes you adjust the chain by that number using inner links. - Usually people go smaller on the front or a larger rear.. this increases the ratio to give a quicker take-off - (more acceleration).
15/43 = 2.86
15/44 = 2.93
15/45 = 3.00
15/46 = 3.06
..when you get a new chain... better to get one a couple links too long than one link too short!!
Your local dealer will be more than helpful!!
