Ribbon is still intact. Based on what I've read, the ribbon deletion on a TR-1 isn't worth it for the trouble involved in doing it.

I've been able to source a replacement stock air filter from...

You are absolutely correct. I'm not going to put anything foreign into the airbox. In the meantime I can deal with it until my dealer can order in a replacement stock air filter from Yamaha. I'm...

Well this is interesting. Rode yesterday, about 2 hours. About 20 minutes in the lake entrance channel (where the lake spills into the ocean, so it's a bit rough). Remaining time on the lake, smooth...

I bought it because my ski has about 145 hours and the stock air filter was due to be inspected and you can't clean the stock one. Getting Yamaha parts in Australia for the last 2 years has been...

Yep, good point. It's only been in the ski for 4 engine hours so if I decide to do this, I'll clean up the spot with isopropyl alcohol first.

It's only been about 4 or 5 hours since I installed the filter and whilst I can't see evidence of oily film on the filter, I feel that it's too soon to be sure. I was considering just putting a...

Thanks for the response K447 and musubi. I did notice the idle getting rough just before I was putting it back on the trailer after my last ride but assumed it was just because I'd been going through...

Thanks GreenHulk, I will try that. I assume you mean using a bit of Ultra Black or similar on the tabs so it can't shift itself out of the tabs. Thanks again.

I recently installed the Riva performance air filter which uses the stock airbox, for my EXR.

After a couple of days riding, roughly 4 or 5 hours, I noticed that the ski struggled to stay in idle...

I ended up going with the Solas EXR prop and it's gone well. I can't say whether it has improved acceleration or top end - I have no other performance mods. But it certainly cavitates less than the...

Do you ride in the surf much?

I've got an EXR which is much the same.

- Went with Worx sponsons which made a nice difference in cornering and general turning responsiveness - very handy when in the surf and cutting around...

Yep. Managed to get a pic of an FX HO pump cavity where you can see where the FX dumps the water. Straight onto the ride plate. Forward of the exhaust outlet and low.

Looks pretty self...

The only part I'm not too comfortable with is the exit point. In particular, the location of the exit hole. It needs to go to the right of the pump, near the exhaust outlet. I really need to see a...

Have seen the threads about the footwell drains that Yamaha introduced from 2019 onwards.

Going to try and implement the same mod for my EXR. I think this would also be super useful for the...

You're over thinking this. It's not hard, especially for an engineer. There's no guide as far as I'm aware other than the service manuals, but there's plenty of YouTube videos and threads here which...

Hi K447, that I do not know. But knowing OEM pricing, the original Jetblaster steering is probably more expensive.

Just checking (US pricing, from Jetblaster parts diagrams)

Bars...

After trying out a JetBlaster a couple of weekends ago in the surf, I'm convinced that the wider bars make a big difference to the handling experience of the EX hulls. I have a 2019 EXR and going...

I recently repaired, primed, painted and clear coated my EXR hull.
Used epoxy with flex additive to fill the scratches/gaps.
Epoxy primer rolled on and then sanded level (I don’t have a suitable...

Whichever option you choose, I'd recommend a 2K/2 pack clearcoat. I see that Colorrite have a 2K clearcoat option (KK7). The single pack clearcoats don't have the toughness of a two pack. If you're...

My drain plugs fell out while driving down the highway one time. They can be a little flimsy and the plastic retainers could break down. But I noticed you said that your skis live on docks. Must be...

Hi all - would really appreciate some help identifying this rubber (flexible) hex washer. I found it in the engine compartment...

Thanks K447, makes sense. So basically, exhaust mods on 4 stroke engines don't have an impact on performance to the same level as they did with 2 strokes. Looks like I need to leave my 2 stroke...

Thanks for the info. And to answer your question, the point of my question was to ask whether it did actually produce much extra noise over stock as I don't want to p#ss off other people around the...

Thanks everyone for your responses. I think I’ll leave it and will look at the power filter kit instead. I’m hoping that it along with the free flow exhaust doesn’t create too much extra noise over...
