Had to take the ticker that had been fixed back to the dealer for a small oil leak. Will hear more today whether it can be fixed or need parts, probably a valve cover gasket.

Next order as soon as this is done I will be going down to see Dale Walker. A shop he uses for his various other projects will be where we will install the header onto my already installed holeshot cans.

At this time I believe Dale wants to Dyno the bike with the full system and do a custom map and check all the readings. Seeing we pretty much know the stockers area all close to the same specs for horsepower, torque etc., this will give us a good read on the difference between stock and Dale's full system.

This should be happening soon as we have to coordinate Dale's schedule and the shop availability. The shop is about ten days out on the calender. I will keep you posted.

 
Good luck on the oil leak. It probably is the valve cover gasket. Same thing happened to mine on a recent valve adjustment. Problem was, valve cover gaskets were on back order and took about two weeks to get in. Hope you have better luck.

 
Just a valve cover gasket leak. Put on a new one. Saw the old one and when compared with a Kawi gasket of unknown origin, the design on the Yamaha by explanation of the fitment of the two, Yamaha design isn't as well thought out. But its fixed and got a free oil change out of the deal if in fact ist wasn't supposed to be done when the valves were done.

 
make sure you do back to back dyno runs with the stock vs. the new system. I see too many people have runs by them selves which really don't tell you anything besides what the torque and Hp curves look like. hopefully it's not a problem and it's always fun to see them back to back to really compare and see where the advantages are. personally I think just being able to fix a little bit more of the heat issue (remove the cats) is enough of a reason to buy a full system!

 
Exactly. This farkle is more to address the cat/heat issue and make the bike breath and run smoother. We can't do a completely stock as I already have the cans installed but there have been numbers posted on stock.

 
fjrvtx1300s, I know your bike is the one in the sound videos on Dale's website. Did he use yours for the dyno tests as well? If so, would that be a close enough comparison or are you going to do a baseline test with slip-ons only, then change the header?

 
Wouldn't dyno runs be better off made during the design process?? I'm not sure how Dale and the competition does it, but I'm sure you don't design headers for a big bock Chevie , then flow them?

Hey what do I know, just throwing it out there for an education! :)

 
No, I only did the sound and video for the cans only with stock header. After talking with Dale several times and spending a day talking performance from one of the inovators of motorcycle drag racing, Dale knew there was going to be little gain in a full system. Thats why he took so long to get the header out. Horsepower gain per $ is just not there. But he knew that the heat issue with the way the cats are installed would be a big improvement with the PC for smoother running and programable performance. He also knew that the FJR is limited for horsepower with just his system without getting into the air box and he thought that just might be a crap shoot. So I am just happy that I am going to reduce the heat, richen up the bike and have smoother performance with a little more rumble to the pipes. So if you think you are going to turn the FJR into a Busa with a little mapping and a header your wrong.

 
I dunno Mike, there's gotta be something we're ( I'm ) missing here? It can't take 1 1/2 + years to develop some straight header pipes. There must be some design / flow work somewhere, otherwise they're just stock Yammie pipes with the cats and crossover removed. ( They do look pretty bitchn tho ! ) :agent:

 
IIRC, Dale Walker said that he had a test mule to use to build the header. I believe he had to wait until he had the bike and the time. Perhaps he returned that bgike before he had a chance to run dyno tests on the complete system.

 
Basically thats all they are. He opened them up, I believe an 1/8 inch and coated them inside and out for the heat. The removal of the cat opens up the air flow big time because of the cluster f**k down there. He took so long to fit and he had other priority pieces to make first. There is only so much you can do and sometimes in the FJR's case it is not like a Bandit or FZ1. He wasn't even going to do a header because he felt there wasn't massive imnprovement in horsepower but went on with it to sell a complete system and adress the heat issue. After all his years in the business of going fast and producing horsepower I believe he almost knows from the start what going to happen. If you close the header down you get nothing and if you open it up to large you get nothing. Sometimes it only inproves during a certain range but doesn't give you improvement in all areas. He doesn't think you need to tune each cylinder on a bike like this but some think they want riv nuts to do so. So I think you could reengineer the whole system but would have to get into some kind of air induction system to go farther.

Plus he runs a business and it has to be cost effective, time to design related to number of full systems he will sell. Not many change their pipes etc on a bike like this.
