CBR F4i Trackbike Project.

**toybm** · 04-29-2010, 04:25 PM

This is my Trackbike that I've had from fall of 2009, it worked well until the first track outing for this year and splat, 3rd gear is doing something wonky after a false neutral. So after getting a few quotes for repairs and having to continually pick my lower jaw up off the floor, I decided that I will get into it myself and be ready for Round 1 on 7th May.

Whats on the agenda;
1) Install used engine I bought from Cory (good guy) out in Sarnia (loooong drive)
2) Install FactoryPro Evo Star Shifter - to reduce the false neutrals and give better overall gear engagement (if I get it in time)
3) Install CBR1000RR Kill Switch
4) Install CBR1000RR Throttle Housing with 08 R6 Throttle Tube (OEM 1/6 quick turn throttle)
5) Install CBR1000RR Front Master Cylinder
6) Attempt to fix 3rd gear issue in original engine or seriously thinking about parting it out.

Step 1, tearing down for engine removal

After 1 Hr 30 mins we are obout ready for step 2.

Tomorrow engine comes out and new one goes in.

Nice!

Does the new engine have a manual cam chain tensioner?

Thanks. No manual tensioner at the moment, but as soon as I recover from this spend-fest I'll surely get one.

Way easier to put it in before the engine goes into the frame ...

Did the spare engine you bought include the wiring? I'm looking for some wiring harness peices for my F4i project. If it did and you don't need it I would gladly take it off your hands.

Sorry no such thing, bought only the engine that stuff is extra.

UPDATES

I haven't ridden the bike for some time now and it has just been lying around so I decided to install a few things I got a while ago, FActory Shift Kit and Ignition Advance. So, here come the photos.

After draining oil, unplugging the ignition pickup, taking the clutch cable and clutch side engine cover bolts off, the cover is removed to reveal the clutch and ignition rotor. Actually getting the cover off was not really difficult but stressfull.

Time to install the shift kit, which is made up of a new shift star, arm with roller bearing and spring all behind the clutch assembly (yippie).

Clutch cover, springs/ bolts and a few plates in engine cover

Crack that big nut!

Some tissue just in case something wants to fall somewhere I didn't want it to

Where are those springs and bolts

Time to clean gasket surface and install engine cover, clutch cable, plug in ignition pickup, new oil and start.

Bike started up first turnover and sounds great, now I'll have to wait till next year or maybe brave it in 5 degree weather in November (I doubt it).

Oh yes I also installed a 14 tooth drive sprocket, wanted to go with bigger driven sprocket but chain was too short. I'll see how this setup works.

Nice work man. I am loving all the photo documentation. Especially the comparison shots of the parts.

Short Update

1) Did a trackday on the 17th at TMP, happy to say everything stayed together and the bike ran smoothly. The Shift Kit greatly improved the positive feel of gear changes, much better than the stock shifting mechanism and I never felt the vague gear changes like before.

2) I had a Dynojet quickshift switch (I think I posted a pic) and I got a MPS engine kill box (no pic), wired them together and was doing WOT shifts without a hitch.

3) Finally I wanted to see what map was on my Dynojet but my computer had no RS232 port, crap..... so off I went to purchase a RS232 to USB converter and after installing on my computer I was viewing the Map in 30 mins. I saved the Map and am going to try appropriate maps at the next trackday.

4) Finally, I have nothing else really planned for this bike, I will use it to learn as much as I can and get a better more modern one when I could. Me on this bike have done high 1:18s and 1:19s and that`s with my noobness, I`m sure with better skills and confidence, 1:16s are possible.

That's it for now, thanks for watching. PEACE!
