I run 15/50, so pretty large sprockets which isn't helping. YZ450F swing arm is longer as well! 15/50 is perfect for this engine. Think I need at least 116 link just to get correct chain tension with axle moved all the way forward. Maybe even 118 to ... more »

Those with YZ450F swingarms, did you have to get a longer chainl? Mine is a bit too short now vs YZ250 swingarm. I'm all the way forward and the chain is still too tight. Both the YZ250 and 2014 YZ450F OEM chain is 114 links. Also, looks like I'm stuck ... more »

Just got proof for swing arm graphics. Had to put Luxon on since he helped me out with it!

I forgot, whats he doing to yours? I know he said a ported YZ295 was 49HP on his dyno, but I think his reads a little low. New stock on his dyno was 44, but I know some other dynos get 46. Not that important anyway, as long as on same dyno you get improvements ... more »

Well I asked him to since it was already apart

I'm guessing 58HP... Maybe 60 on a happy Dyno. Stroking is where the power is at, but not cheap! One day I will ride it

It's effectively 41mm with combination of bore and hand porting of carb and reedblock.

Added reply in a thread 2006 YZ250 (Tom Morgan YZ315 Stroker) 7/29/2019 8:15 AM

72mm bore x 76mm stroke.

Taper didn't change it much. I tried from 182-190 main. 188-190 is it's sputter point on top end. 185 clears up nicely, but I have 182 in now. May go back to 185 main. Needle N3EW 2nd position Pilot 55 about Power Jet 55 Air screw .75 turns out VP C12 ... more »

Yeah, I'll try! How long is it good for? I think Billy is right, my calipers are probably good enough. But little more leverage from 280mm rotor might be worth it. Thanks

Added reply in a thread 2006 YZ250 (Tom Morgan YZ315 Stroker) 7/26/2019 12:51 PM

That's actually what it has right now, 2008 CRF450 MC, Caliper, steel braided line, new Honda pads and stock Yamaha 270mm floating disc. If the after market calipers aren't much different, I'll just skip it.

Yep for sure! Was pretty easy for him. I want to bring bike to Red Bull Straight Rhythm. Who wants to ride it?

Next item on the agenda. Ride Engineering vs Motostuff front calipers? Ride Engineering is much cheaper, especially on RMATV!

Billy got it it squared away! I think it was .100"offset but Billy measured, lathed it and installed a spacer. Will be cleaning it all up and re-greasing everything!

Talking to Billy @ Luxon about this. Will be bringing bike up there to figure it out! Thanks guys!

For sure, would be willing to try! Sent you email. Thanks!

Great info. Do you know when they will start selling the new caliper? Mines not too bad, but I am aggressive on front brakes. Right now I have 08 CRF450 master cylinder and caliper with stock 2019 YZ250 rotor and steel braided line. For sure much much ... more »

I want to do swing arm, maybe some Ti, big brakes... Already have the 2008 CRF Master cylinder and stock 270mm rotor. Would like to do the Motostuff caliper and 280mm rotor but that's almost a grand! What Ti bolt kit did you get?

I'm liking the R-tech better so far, just more modern looking and different. Not sure what to do next, but really want to get rear springs powder coated..maybe candy apple red! One of these days I'll get a chance to ride it
