2017 YZ450F - Basic Mods and Tips (Vet Rider)

[Armbarn sailor]

Guys, I just expressed an opinion on the current YZ airbox design, which I find to be less practical than the “conventional” design Yamaha used until . I said it requires a bit of extra caution, and I also suggested a solution (use the Twin Air airbox cover). That’s it.
[mention=357033]hondaman331[/mention]: I find a bit ironic you ask “what this fuss is all about”, and then you suggest to remove seat, tank and rear airbox shroud just to change an air filter. ?
 
 
 

Irony is spending 10 grand on a bike and not going the extra mile to make sure it doesn't get dirt stuffed in engine during a routine maintenance procedure.... but I like making sure my bike fires up and does what it's supposed to without a hiccup!

Fork wraps on!

Those fork wraps look very familar... well done! Did you get them with the dimensions I suggested?

Yes I emailed them about the custom sizes and they were quite easy about it. I didn’t measure to verify, but the are 1/4” from the lower clamp and overlap about 1/4”-5/16”

Glad to hear that. If you look at the photos I posted at the beginning, you will see that I used some electrical tape right below the triple clamp to make up for the gap left uncovered by the wrap. More difficult to explain than to do...

I thought that looked like elec tape. Looks clean enough. That’s been the way to finish bar tape on road bikes for a long time ??

I like the Yosh. Looks good.

just picked up a leftover 17 today. bike is awesome. Crazy hit right off idle. Did you find swapping to the linear map really eased up the bottom end? i'm coming off a 250f so having low end snappy power is not at all what i am used to.

Yes, very much so. With the stock map, the bike was so responsive down low that I really had to be careful rotating the throttle. Once you get used to it, it's not that bad, but I was not enjoying it: I like to ride smoothly (I'm faster when I do that) and having a bike that takes off under my butt is not what I need.

I only tested the Linear map once, but I liked it immediately: the power is still there, but it doesn't hit so hard. It might even be a bit too tame, but I know that I can dial things back a bit, and find the perfect compromise. I agree $200 is not cheap, but again I'd rather invest in something I can use many times (and re-sell with the bike) than wasting $50 for a dealership to do it (once). You can try and find a fellow YZ owner with a Power Tuner, at the track or near you, which is willing to do it for $20 or a pack of beers.

Thanks for the feedback. The bike also came with the gytr full FMF exhaust. But it looks like the linear map should still work fine even with an exhaust. Tuner should be here Tuesday
