2004 track bike build, r6 front (pic heavy)

That has got to be one of the most original looking pregens I have ever seen. How did your track day go? How does the bike run/feel?

track day will be this coming weekend at streets of willow. going with Los Angeles Motorcycle Riders (march 29/30). ill know how it handles once i get on SoW. front is 120 and rear is 140 so i hope the turn in is still sharp enough.

currently bike is lagging mid range for a hot second. going to tweak the jet settings one last time. got the speedo to work too

[Major_Paine]

tweaked the idle mixture screws on the 250, runs better.

also, special gopro mounting area

track coming up this sat at Streets of Willow Springs.

just about have everything ready now. Finished painting everything, and just bought a ton of seat/tank foam from HTmoto. there minor things i need to add later. I will post a vid of the track day/ more photos in better lighting and details after track.

this time: blue loctited a few more bolts down. traced and cut the foam to the right sizes, peeled off the backing and stuck em on. for the seat i had to do the same but drill holes to zip tie it down and keep it in place. sorry for lack of progression pics, but i really needed this to be done before friday, which is when im taking off for track.

heres what it looks like as of right now

after riding this at streets of willow, i have made the decision to swap the front end from r6 to inverted gsxr forks. this means 2 calipers and rotors to my current 1 and also more tuning options for suspension.

already got the complete gsxr front. will be updating soon

[Joshua763]

looking forward to seeing the new front end.

or track video.

Here is the new gsxr 750 front end. need to readjust quite a few things. but at least it is mounted. i will edit some track vids and throw them up here when i get the chance

[Joshua763]

Seriously you are great. I have a naked two thousand two crash victim that has three thousand five hundred miles and love the idea of a bigger front end.
I cant wait to hear about how it rides or even see video. Thank you for the thread!

interesting, how much had to be changed between the R6 and GSXR front ends

my pleasure. so far there are minor tank clearance issues and the rake angle may or may not be off. i cant lower the front anymore otherwise the triple wont hold the forks in place. ill see if my friends have footage up of me (with teh r6 front)

it is an entire front end swap. as in i bought a gsxr front with: triples, forks, clip ons, rim, rotors, calipers.

you can swap all hand controls tho: grips, clutch, brake, throttle etc

Yeah I just meant you had the R6 unit and now the GSXR unit and was curious if one required alot more work than the other

OH haha. It is the same process as installing the r6 front.

You will need to buy tapered bearings, remove the old race, drive in the new bearing. The just elevate the front end of the 250, slide out old front, slide in new front. adjust as desired. Its pretty straightforward/ not too difficult as long as you have the space.

Having the right tools (especially the bearing driver) will make this a 30 min - 1hour job vs a few days

~~~quick clip of the bike on the track (with the r6 front):

Link to original page on YouTube.

excuse my bad riding. i can come up with a multitude of excuses, except i know im just bad :P level 2, streets of willow, first time ccw

in terms of handling: i would say the r6 front is significantly stiffer than the 250 front and more stable. having the option to adjust settings is such a huge plus. the larger brake rotor/caliper and steel braided lines also gives better braking vs stock 250 brakes. turn in is just as sharp, the 120 wheel doesnt feel any bigger to me. the woodcraft clip ons are adjustable to height and angle, so you can make this as aggressive as you would like.

the mods to the airbox/exhaust were noticeable. even though the bike was not rejetted perfectly, i was able to pull up on other 250s (cbrs and ninjas) that had just slip ons or were stock. i also outweighed those ladies by a good 50-75 lbs. i guess it also helps that i removed a ton of stock weight from the bike

The rear suspension was definitely stiffer than normal. no sagging but absorbed all the bumps. also needs to be dialed in for my riding style and weight.

the biggest gripe i have is that the stock seat prevents me from scooting back from the tank. the banana style curves up about 3-4 inches closer than the cbr 250 or new gen 250 seats. so i bought a gsxr seat, might buy a nsr 250 rear race cowl, and will adjust that accordingly. Body positioning felt uncomfortable all day. this may not be an issue if youre shorter than 5'10'' but im not 100% sure.

Next plans are to either get new adjustable clip ons or use the stock gsxr ones. need to find a gas tank or do something so the steering clears the tank. adjust the seating. rejet the carbs to a bigger main and pilot and readjust needle height. its too finicky at the different elevations and im afraid it will crap out on me mid ride

I didn't think I would get to see a crash too. Looks like a lot of fun on the track. I will think about changing my seat. I don't plan on touring on this bike.

[Major_Paine]

woah someone went and did the embedding for me, thanks haha!

that crash was a pucker moment. came out of 3 and lowside in front of me.

i almost ate it in the skidpad when i was leaning off the bike. back end slid out because of a bump, but luckily the bike was light enough that my knee draggin a few inches sideways (unintentional -.-) allowed the rear to regain traction

Yup - you caught me. Hit quote on your post and you'll see how I did it; you just need to put the video ID within the youtube tags and it will work fine; you can't put the whole URL in there.
