there are actually 3 Fujitsubo LegalisR... one is a single tip big muffler, a 2nd is a dual tip big muffler, and the third is a dual tip small muffler (yes - a bit more noise). I've now had 2 of the 3 Fujitsubo exhausts. I've had both dual tip models. The small muffler version is a bit too loud for ...

That "rattle" depends on the alloy of the forged piston. Typically... 2618, they have been known to make some from 4932, but they don't recommend it for boosted applications. I'd like to see hypereutectic castings for street apps. Hyper pistons are lighter than reular cast and forged pist...

The pistons I just showed in my previous post.... This is essentially a stronger smallport piston. https://gallery.ostportworks.com/albums/userpics/10005/normal_OST_Traum_high_comp_copy_versus_OEM_high_comp_6_panel_large.jpg Full size image - https://gallery.ostportworks.com/albums/userpics/10005/OS...

speaking to seat time..... I've been on track twice.... 3 times if you consider carts.

I get motion sick

I can build them, just can't take the g loads.....

best of luck in 2 things: 1) your seat time, and 2) keeping to your budget.

While this is a mixed generational head, the intake casting was SUPERB.... note the bowl casting comes all the way out to the edge of the seat. https://gallery.ostportworks.com/albums/userpics/10005/good_port_alignment_-_arrows.jpg In all my years working these heads this is among a handful that wer...

https://gallery.ostportworks.com/albums/userpics/10005/normal_OST-093.jpg Essentially there are 3 types of 16V 4AG heads. There are 2 versions of the largeport, and of course the smallport. The early largeport (1984-1987) was originally designed/built(?) by Yamaha, where the later ones(1987-1989) w...

253hp under 9000rpm is really good! Especially NA. Cams I'm running are a grind from Kamakaze cams, got them through Matrix garage, 266*/238*@.050" 8.65mm lift at cam. Decent cam, timed now for smog and smoothest idle. Pulls good from 4000rpm all the way to fuel cut, stock ECU. change the timi...

Not $1000, but for $700 you get pistons, rings, pins and locks in the bore size (and compression height) you want. https://gallery.ostportworks.com/albums/userpics/10005/normal_OST_Traum_high_comp_copy_versus_OEM_high_comp_6_panel_large.jpg As far as smallport rings are concerned... you might get an...

As to why stock pistons break ring lands it all has to do with poor ring land support

1900cc? What build was it, 4A or 7A? As 83 x 83 only equals 1796cc, it would have to have begun as a 7A build to get to 1900cc. I'm pretty sure this is it.... https://www.club4ag.com/forums/viewtopic.php?f=4&t=1016&p=3451&hilit=billy#p3451 That's what I was shooting at. I just didn't wa...

Well.... I've had some excitement since I last posted. First, in May of 2021, I got SUPER lucky.......... one of the oil cooler lines let go, the braided hose began leaking internally! https://gallery.ostportworks.com/albums/userpics/10005/broken_cooler_lines_removed2.jpg Caught it before I ran it o...

Bit of reading for you 5AGE guys... https://i.imgur.com/NTnORxo.jpg Cheers... jondee86 shame the HKS pistons aren't using typical HKS numbering.... I acquired an interesting kit recently...

A bit further..... ready for reassembly https://gallery.ostportworks.com/albums/userpics/10005/liners_installed_ready_for_re3Dassembly1.jpg As this is an aluminum block, there are all kinds of stresses when tightening the main bearings in place, and setting the proper torque.

Mannon's girdle incorporates ladder caps into the girdle. Nice piece! Expensive too. What’s the best head gasket for this setup? I’m assuming cometic or something, probably at least a 1.0mm right? 0.8mm may be too high compression with the pistons being 12.5:1 Get deck measurements for all 4 piston...

As per the TRD Bible.......

If he wanted boost he could have boost, but he didn't ask???????? OP do you want to run with boost???


Desire....... Budget......

With the OP looking to purchase a stroker kit - his budget is likely adequate. What is his desire..........???????????

one thing to consider when building a stroker... is "journal overlap". Essentially, a 7AG with the larger rod journals (45 versus 42) is stronger.....

Big valve heads too

whoa..... I answered this... and it didn't show

yep.... happened to me too.

Me thinks Moto needs to do some maintenance.... I still can't post photos.... and I have to sign in every other day
