most all naturally aspirated internal combustion engines have a tendency to follow this trend... :wink:

Going to the dunes in just a couple weeks for the first real ride to speak of...

I know that guy... :biggrin: But, yes, 700R a-arms are the same as the 450 arms. Case of beer is a better price than anything I've worked before!

Easiest place is prob the Yamaha shop, I think I paid like 1.95 a bolt, you'll need 4 of course. Might be able to find something if you Google Yamaha OEM parts?

No you don't have to run the 450 calipers. I thought I had mentioned it, but you WILL have to pickup some YFZ450 caliper bolts. With the aluminum spindle, the caliper mounting bracket surface is a bit thicker and the stock bolts won't reach.

I'll take those at $120 shipped including Paypal. PM me and let me know. I work until 10 PM PST tonight, so I prob won't be able to respond until then, but I want them and pay fast. No, "I'll get you money on Friday" stuff here...

No, I totally agree with you in most regards. I've done all of my tuning prior just by looking at plugs and paying close attention when I was riding. I can tell you however, my 50.6HP pass sounded the same as the 55.7HP pass. However, when you looked at the curves, there was a huge difference. Sorry, I'll stop now, I don't want to hijack the thread.

The HJR dune ported 4 mill dyno'd at 60HP? That was more than yours or you stomped him? Do you know what his setup was? I just dyno'd my T5 bike that I ported at 55.7HP without tuning and too big 20cc domes (instead of the 18's that just showed up from David @ NOSS). I hear great stuff from a lot of people about Kevin's work!

Okay, so I know the intakes are impressive looking, but the real work is in the exhaust and the transfers. Take some pics of those and post them up. That tells worlds more than anything else...

Bump, buy pipes! I got mine out of the same series as MOFO, agree on fast shipping and great prices.

Another bump for BoostedRex. Great prices on pipes, fast/reasonable shipping! I will hopefully be able to play with them in the next week. Thanks! - Brian

Yeah, I was really hoping break into the 60's, but maybe that is a little ambitious for a first time DIY port work? I don't really think I'll go down the cub road; I prefer the stock look. I'd love to keep tweaking, porting and tuning to try and get into the high 60's or even 70's with diff carbs, pipes etc. My CPI's just showed up from BoostedRex, man are those things FAT!!! I'm actually looking at picking up a set of OKO 30's just as a test of the bigger carbs. I'm going to be working on your cylinders for quite a while tomorrow night. Should be able to finish up the intakes and the transfers. Still waiting on my cases so that I can set the port timings... Oh and I have to get some money out to mopar for a spare crank, I didn't forget mopar...

Peak HP without ANY jetting adjustments at all when it was on the dyno was 55.7HP. My initial pulls only made 50.6HP and 31.8 ft/lb of torque. BUT, the filter was disguisting dirty. I was getting really dejected, but the dyno owner/operator recommended we pull the outerwear and make one final pull. That's when it made the 55.7 HP. 5.1 HP loss from the freakin' outerwear!!!!! The filter was disguisting underneath the outerwear still. So, with swapping out the domes, cleaning the filter and fine tuning the jetting, I'm pretty confident I should push the 60HP envelope hard. So, back to the drawing board for now. I don't feel ashamed of the numbers it put down, but I'm hungry for more! Next cylinders should make more and will have much more aggressive timings. Darthwall, after this run, I'm pretty confident we should be able to put together a hard running combo. Did you recognize some of the latest pics? :biggrin:

Good guesses... Keep them coming, I'll drop the numbers here in a few. Are you guys hedging the numbers down figuring it's rook doing the port work? Or would these be numbers you'd be happy with? I'm expecting a good jump when I get the right domes in there and clean the filter like it should have been. Had to have my dog put down this AM literally just before I pulled the bike, so didn't have a lot of motivation to get everything prepped properly...
