I sent another email last night and got a response this morning. They've been shipped out and should see them in a few days. He also mentioned the move between shops and being disorganized. Hopefully after the move things will get back to normal.

He said the original case hardening should be fine for boring the hole from 25mm to 26mm but will check when complete. te4250, sent you a pm

It took about 5 weeks since crankworks got my crank and got the quote/estimate phone call. Guy knows his stuff and we were able to make a few tweaks to my order to get everything perfect. Was originally going with 133mm wsm rods and switched to hotrods brand. He says in the past few years...

I still haven't received my replacement mounts, even though they were supposed to be shipped 4 weeks ago. No contact aside from a message to jetmaniac about shipping my mounts.

checked my b-pipe headpipe and a #53 drill fits through, so about 0.059"

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...

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.

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.

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

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...

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

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...

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...

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...

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.

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...

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...

Exhaust port width is 56mm at widest point, so about 66%.

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