    Any contact with Rhaas?

    Jetmanic sent Rhaas some texts on my behalf. Took a few days for them to reply back, but I'm now told they would be shipped out tuesday(11/30). I ordered a brand new set of oem yamaha couch mounts to start fresh next year. That's the original reason why I ordered the rhaas mounts. I didn't...

    H20 designs/fast elements?

    I like the adjustability of them for my smaller etx9 battery, but after a couple months of hard riding the sides bent outward. It was probably from the battery straps not having enough tension, or the dozens of side flops.

    H20 designs/fast elements?

    I purchased a couple of his battery boxes back in june. About 4 days after my order confirmation I sent a facebook message and he replied that they were out for anodizing. It took a few weeks but I eventually got them. Look up fast elements on fb and send him a message.

    Any contact with Rhaas?

    I'm using a used set of oem couch mounts right now that I've been happy with. My plan was to get the warrantied set, sell them, and buy four brand new couch mounts. Damn

    Any contact with Rhaas?

    I tore a set of Rhaas couch mounts a few months back and I've been trying to get them warrantied. Emailed them october 1st, then every 2 weeks after that. Jetmaniac suggested I ship them back and gave me their address. I did that, and they were delivered november 6th. Still no contact. Any...

    What's your view look like today?

    I had the same 1979 55hp johnson on my 10' invader. Great motor and power for the weight.

    61x topend and stroker cranks

    Making more progress. Crank is shipped out to Crankworks. Head is pinned. Not much room to do that, but there is two small areas for 1/8" pins. Modeled and 3d printed a template for a base spacer. Machined a plastic pattern and cast in aluminum. Left about 1/8" extra stock that was...

    61x topend and stroker cranks

    I did see the cylinder pictures and agree, something let loose. Overall the crank is decent but I can easily feel something in a couple of the bearings. I'll be sending it to crankworks soon for a full rebuild and install of 133mm rods. He'll have to bore the crank pin holes out to 26mm...

    61x topend and stroker cranks

    Engine is stripped down. Turns out the base gasket was never trimmed around the transfer ports. I'm sure that didn't help airflow. The crank fits, but the big end has no clearance. Kept the same clearance to the crank webs, about 1mm. The crank is in good shape, however one of the inner...

    61x topend and stroker cranks

    This rad crank has stock 125mm rods. I believe the hpe kit has 133mm rods. Ideally I would like a long rod setup for less stress on the pistons, but working with what I've got for now.

    61x topend and stroker cranks

    I got the degree wheel out and rechecked my current port timings. Exhaust opens at 89 degrees atdc(180 degree duration), transfers open at 118.5 degrees(121 degrees duration) with blowdown at 30.75 degrees. All more or less in line with what I measured before. I pulled the exhaust manifold...

    61x topend and stroker cranks

    I remember reading that in my earlier searches. The peak rpm sounds right too. 8000 rpm stock stroke piston speed is about equal to 7500rpm 73mm piston speed. I was planning on reducing the rev limit and take a couple degrees of timing out. Currently set at 8000rpm rev limit and a modified...

    Yes, he said it was from a riva 750. Should I be worried?

    61x topend and stroker cranks

    This past season I've been running a 771cc 85mm bore with aftermarket 44sbn's, bpipe, and zeel. Most of the year was 180psi, and a couple gallons at 200psi. I've been extremely pleased with the power output and have it tuned perfectly. No fouled plugs, no hesitation, no chugging. I'll be in...

    Want to Buy 5mm cylinder topend

    Damn really. another cylinder for angry people to attack people on

    Have you compared your porting for this cylinder to a jm big bore? I know the powervalves are a game changer for the smaller bores but I'm curious what I could expect doing a direct swap from my 200psi, dual 44, zeel, bpipe jm771.
