Project V7MW WERA bike

Postby Insulinboy » Sun Nov 17, 2013 1:57 pm

So as some of you know I purchased a track bike on the forum this past week. Its been sitting for 3-4 years and has been abused by many a forum member before I got my Phalanges on it.

The for sale thread with some links and photos and backstory of the motorcycle

viewtopic.php?f=19&t=67909

Me all ready to go pick her up

And after pickup I took some photo's while stopped for lunch at my aunts house not far from where I picked the bike up (about 2 hours from my home)

002.JPG


I'm ready for my closeup Mr. Deville

004.JPG



The purpose of the thread:

I'd just like to document the work I'm doing to the bike and share as well as get some tips and help along the way because I'm going to be undertaking some tasks I've never done before. Keeping everything central into one thread will help me, and help to keep the history of this bike a part of the forum, Kind of like the history of Ashwin's 788. Since I'm the third forum member for have had this bike I see it as a part of the forum. I'm the third person learning about racing and track days with this bike


The plans:

Originally I wanted to start with some fresh body work. The body work on the bike is all tore up, as to be expected with a bike of this age and history. It's not a spring chicken and that's not what I expected to be buying. However new body work would cost me just as much as the bike cost me when I got a new underbelly, front fender, and nose cowl. I may still buy a used front fender if one pops up here cheap because the one on the bike is missing a few chunks and that is a cheap one to replace. The nose cowling is also missing a few chunks but is otherwise in good shape and I probably won't do much to it other than paint. The belly fairing needs some help though, its all there but chunks are broken off and taped on, this I will need to permanently fix to make it legal.

I hope to have the bike ready for when WERA comes to Road Atlanta in 2014 so that I can take my class and get my licence and get the bike registered and start racing. There is a member from the superhawk forum that travels for points and rides an FZR400 with a YZF600R powerplant that will be there and can offer support and help to me as I get antiquated with the rules, regs, ect. I'm not sure of what colors I will be using yet, part of me wants to keep it red because that way it matches my good leathers and is color quarantined with the hawk, another part of me wants to paint it similar to ron's paint on the 788 and try to register the bike with the number 788 and have a photoshoot with ron's 788 at some point (like maybe the gap meet :-p)

Anyway, off to the garage to start my work on just getting her going again after sitting for 4 years with stale gas :( actually by now its probably varnish or lacquer :( :(

So today I was hoping to drain the tank, quick go through of the carbs, charge the new battery and maybe hear the bike run tonight before bed..... no such luck. 4 year old gas is bad mm Kay? If your going to leave a bike to sit that long, do yourself a favor, throw some stabil in the tank, run it through the carbs, and then drain the float bowls.

Anyway a few pre dis-assembly photos

005.JPG


Removal of the tank and the tail was next

007.JPG


And then remove the airbox and carbs

008.JPG


009.JPG



upon opening the carbs I found this

:( off to the parts store for a few gallons of carb clean :/

So no photo's today sorry. But after soaking the carb parts in cleaner and getting 120 psi at the jets in air pressure she runs again :yay:

She is severely rich in the bottom still.. I dropped the needles to try and compensate but its not enough. I'm going to pull the carbs again and put some smaller jets in it and see how it runs. According to the dyno Tom had done though it was perfect 8-13k, but below that its just retardedly I don't want to run rich.

Any advice on that front? from my understanding you move the needles to compensate for the bottom end and you change the jets for the top end, but it wouldn't be the first time I was wrong

A little rich on the bottom may not be bad, if it's perfect in the top end. On the track, you're going to want to keep the revs in that 8-13 range, otherwise you're just gonna dog it out of the corners. Remember, you're going to tune it for maximum performance in the power band, not overall rev range.

Main jets can drive the whole thing, so if they are way too big then the whole works may be off.

Try smaller main, raise needle a notch and play with the idle mixture screws.

Are there any engine mods or major exhaust changes from stock?

I understand that, but I'm going to be out motored anyway, so I'd just rather have it run right through the whole rev range.. the 1 or 2 hp I'd gain from having it spot on on the top isn't going to win or lose the race from me

sorry Karl didn't see your post.

Bike has a factory pro jet kit installed. I cant read the jets that are on it but the kit has 122, 120, and 118's still in the box. Stock air filter, full micron exhaust including headers

So I took the bike for a quick trip up to the road and back.. okay so I took it to the neighbors driveway and back, and holy shit.. I don't remember the YZF being that much of an animal :drool I'm thinking I may live with the rich on bottom, because you don't feel it anymore past 3k and it just takes off. I still have the unmolested set of carbs apart with the jets soaking so I can try them for comparison and see if it just runs better with stock carbs... but damn.. even to be a race bike with the footpegs set back and a little higher, pain in the ass race seat, and the handlebars relocated under the tripples it still feels more comfortable than my VTR. It just feels natural to sit on the YZF, of course I've always been more comfortable on race oriented bikes, I don't know why.

Quick video of he running. She's already warmed up, you can see the lag from when I pull the throttle and when the bike actually revs. It almost acts to me like its lean and not rich, but I know at a certain point you can be so rich it acts lean. you can smell that its spitting raw fuel out the exhaust though and the Dyno shows that its rich. I have a stock set of carbs with the jets out and soaking that I will be putting together tonight to see how it runs on stock carbs. It has plenty of power and get up and go though :)

I opened up the choke halfway through to show that it really doesn't run any better with the choke on, it just holds the revs up to the point where it runs better anyway.

Cleaned out the spare set of carbs with factory jets and needles.. Bike runs perfectly now :yay , well, other than needing to be synced

I haven't figured out if I will try to figure out the jet kit in the other carbs or return them to factory as well. I'm thinking probably factory

Perfectly said.
also, spend money on suspension, do the r6 shock swap and some racetec fronts, its worth every penny.

Already have Ohlins suspension in the rear, I'm going to send it in to Daugherty Motorsports (A friend of mine and springs are MUCH cheaper than racetechs, same springs and he cuts the spacers for you so its just pull out and throw in http://www.daughertymotorsports.com/) to be rebuilt and as well have him revalve and respring the front end for me. I already re-sprung my hawk with his springs (and I have some racetechs to compare them to so I know the springs are the same) and it is a night and day difference from stock. Plus its $85 for his springs shipped instead of $120 from race tech plus shipping. He doesn't have a set of YZF forks to measure the cut for the springs so he doesn't have them listed on his site (he has the right springs, just doesn't know the length to cut the spacers) so after I send them in he should be able to hook up anybody that wants new springs for the $85 with the pre cut spacers


Edit: Tires and suspension are the only places I plan to spend money this season. I'd like a new upper and lower from airtech but I just cant justify that.. I need to figure out how to repair the ones that are busted up that are on it.

I bought my spring kit from Sonic Springs. Came with the springs, spacer material, washers, and good instructions for around $85. That's with shipping. (Give or take a few bucks)

Hey Adam, you should contact Dale (Turtlecreek) and talk to him. I may be remembering wrong (mind is gone, comes with old age.. haha), but I think he did some front end work when he had it.

I race R/C cars.. and you would think that would be a cheaper hobby.. but believe me I know what your talking about.. before tires, fuel, or any other consumables there is about $1500 sitting in my Race R/C car.. you can say goodbye to another $60 worth of fuel, and $500 worth of tires at a big event pretty easily.. plus big events are normally a $75-$100 entry... If i didn't co-own and run a hobby shop I couldn't afford that shit :lol:
