G'day everybody. Have a few question, Haven't had a road bike for nearly 15 years and wanting to get back into it so went an had a test ride on a '88 2kr at the weekend. The thing stops and steers good and pulled like a pack mule to about 12000rpm, wound up very slowly to around 15 and then went up to 18 with more enthusiasam. Having never had a multi-cylinder 4 stroke. IS THIS NORMAL??? It's only got 16000k's and probably never had the valve train checked. How often are service intervals?. Even better, Where could I get a handbook/service manual online? Has anyone experimented with final drive ratio to any effect? Quite willing to let it max out at 120 in order to get away from the lights. Also might be able to keep my licence cause I KNOW I'll get a camera at 160/70. Any Kiwis tried to take their test on an FZR? Can't see one handling too well swerveing around traffic cones. As I'm from the U.K, What is involved with getting your licence in N.Z. Cheers, Andie.
Hey man, how ya goin, good to see your looking at an 88 2kr - same as mine! Funny you say it pulls well up to 12000rpm, then dies off, generally the peak power for these little screamers is between 10000-14000rpm - things are a bit sluggish on mine from idle up to 8000, but take off from there on. Don't know much about the "official" service intervals, and there aren't any english service manuals around that i know of (the fzr400 manual is available on this forum and is pretty similar). I'd say it should have a minor service every 7500km and major maybe every 20000km. You can do a lot of the basic stuff yourself with a bit of help and know-how. Final drive ratio - i've thought of doing the same thing myself but bear in mind they do rev hard with standard sprockets and you're gonna be changing gears a HELL of a lot if you mess with it much. Still, i'm still waiting for a report from someone whos done it to see how it goes. Good luck with getting back into it!
where??? bros, juz asking, where in this site i can download the fzr40 manaul or FZR250 manual??? thanx bros. it'll be a lotta help for me. . . . gud day!! <!-- s:cop --><img src="{SMILIES_PATH}/icon_cop.gif" alt=":cop" title="Cop" /><!-- s:cop --> <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: --> <!-- s --><img src="{SMILIES_PATH}/icon_cool.gif" alt="" title="Cool" /><!-- s --> <!-- s:shock: --><img src="{SMILIES_PATH}/icon_eek.gif" alt=":shock:" title="Shocked" /><!-- s:shock: -->
My '89 2KR EXUP pulls strongly from 8000 to 17000 - peaks at about 12-14000 - no flat spots at all. Sounds like yours is not running well at all. My red line is 17000, is yours different ??? DAVE
Welcome to the site Outer...the fzr really shouldn't have any flat spots through the rev range...Although they will peak between 10-14k, You really shouldn't notice much of a difference up to 17,000. This could just be a matter of tuning the carbies. Also the 16,000kms is most probably due to the tacho being wound back. Dont know anyone thats messed with drive ratios. Even though dropping 6th to a max of say 120 kms an hour...As Spook mentioned...you'll be changing gears a lot quicker..and therefore may not actually be worth it? Also cruising on the freeways at 14,000 rpm instead of 9,000 is going to chew your fuel...
You'll find that dropping two teeth of the front and two off the back will most likely only drop your top speed to around 150km/h and will result in near 600 cc. Once you've done this however your going to chew through tyres quicker, eat chains for breakfast, and sprockets for lunch and dinner. If you want to get off the lights a little bit quicker then you'll probably just want to start by adding 3 teeth to the rear sprocket, although that won't change your top end much (down from ~190 to maybe 180). Don't know about you but i get sick of changing gears quickly on my bike through first, second and third... so reducing ratio's would only make matters worse. If you just after a quicker off the lights in a little TLGP race then just practice launching properly (i did a write up of how to launch somewhere around here...), then go for a couple of quick clutchless changes and you'll find yourself outta there considerably faster than you previously thought possible.
ARGH! For some reason i keep getting an error when trying to post the first paragraph... theres mean to be the words 'performance... or atleast a decent clutch-up/power wheelie' on the end.
Nice one, Don't get me wrong. I understand that 250 couldnt pull skin off custard and I reckon my comparison is a bit unfair against my '02 YZ250 LC(P1) which WILL rip your arms off. I'm not too concerned about fuel use or increased drive train wear as this is not a daily ride, more of a weekend hero thing inorder to obtain a full licence. Then I can get my hands on R1/R6. I dropped the final drive ratio on my crosser for racing. On trial rides it max's out about 100k's but the increase on power/weight is just bloody awsome. Any way, Have cash in pocket and just about to jump into the ute and become a proud FZR owner, so in time I will be experimenting and let you all know my findings.
