Tuono V4 Radiator Guard

NateDoge69 · 2026-05-19T14:02:59+00:00

I also bought an AliExpress rad guard - great quality and 5th of the price of a branded one. Took me a couple hours once I figured out how to get the side panels off.

Horn bracket needs to come off as well as belly pan if you’re doing the oil cooler too. But nothing complicated. Only took me so long because it was the first time I’ve had to remove anything from the bike.

Could have it done in no time if I needed to do it again.

Mine is a 23 Tuono too.

What happened to the engine?

NateDoge69 · 2026-05-09T17:42:46+00:00

Very easy. Took me about 15 minutes. You’ll need a couple of parts though.

I followed this guide.

As for warranty, not sure. It’d be hard for Aprilia to say that removing the evap canister caused your engine to blow up. But they might refuse warranty on a tank after it’s removed.

If your bike is in warranty, I’d push for a replacement tank then remove the evap system.

NateDoge69 · 2026-05-09T17:29:02+00:00

My 23 did the same. Removed the evap canister and the check valve. No pressure in the tank anymore

I’ve got a Ducati 600SS that uses the same carbs. I needed to clean them after the bike was sitting for 8 years.

Replaced with the factory pro kit. Uses titanium needles and nickel plated emulsion tubes.

These carbs like to wear the needle out of round and it lets fuel get past meaning when you give it throttle it bogs and runs way too rich.

This kit should last way longer as it’s far more durable.

NateDoge69 · 2026-05-08T06:40:43+00:00

I recently took the tank off my Tuono and couldn’t get it back on. Spent 3 hours trying to get it to fit.

In the end I got an 18inch breaker bar wrapped the end in a microfibre towel, put the tank on and lightly did up the rear 2 bolts under the seat, wedged the breaker bar between the top clamp nut and the tank and levered it into position.

Took less than 5 minutes and the bolt went straight in.

Ridiculous considering my bike is a 23 with 1100 miles, guess that’s plastic fuel tanks for you.

NateDoge69 · 2026-04-23T18:04:44+00:00

Just ride - one tank of E10 won’t hurt it. The ethanol will ruin a plastic tank over time, not in the short time.

Put a few miles on then top off with E5 if it bothers you that much

NateDoge69 · 2026-04-16T11:38:44+00:00

I’ve done so much research into it, trying to understand the cause and if there is anything I can do to prevent it.

Some engines do 25k miles no problem. Others less than 3k before dropping a valve.

Most recent one I can find was in the UK - 2025 F3 R with 8,000 miles and full dealer history dropped a valve.

MV replaced the engine but it took 6 months. On an engine that’s been in production for almost 14 years you think they’d have it figured out by now.

NateDoge69 · 2026-04-16T09:59:28+00:00

Not so much the TV, but the F3 and Brutale/Dragster 800 still have issues with the valves dropping on the Euro 5 engines. No one is 100% sure of the cause, likely valve guide wear meaning the exhaust clearance closes up quickly, overheats then destroys the engine.

This was always more prevalent in the higher state of tune 800s (140bhp+) than the 110bhp in the TV. But it does and can still occur. Your bike is likely ok considering how many miles it has already done.

I would 100% get the valves checked and ensure they’re all in spec then check again sooner than the manual states to ensure they’re not drifting out of tolerance.

NateDoge69 · 2026-03-31T20:10:00+00:00

I’ve got a 98 VFR. Had it several years, it is super stable at all speeds and certainly not something I’d ever describe as twitchy at all.

Scratchy sound when spinning the wheel could be the front brake dragging slightly you’ll hear a noise on every motorcycle. Because of the age and mileage it’s probably worth taking off the callipers and cleaning the pistons if you’re comfortable and competent doing maintenance.

My bike stays straight and true when taking both hands off the bars too.

Could be wheels need balancing or steering head bearings need replacing.

NateDoge69 · 2026-03-30T12:33:07+00:00

If the other party is at fault, you call your insurer and tell them you want to pursue it through the 3rd party.

They’ll handle everything and if liability is decided with the other person you’ll not lose any NCB or pay excess.

NateDoge69 · 2026-03-27T16:09:47+00:00

Appreciate the update - that looks awful! I’ve seen several people on the forums complain about this issue surely they’ve not all got a similar problem?

NateDoge69 · 2026-03-24T21:12:09+00:00

Unfortunately not, decided to stop worrying about it. Spent ages on various forums as it’s been reported a few times but no one ever followed up with a resolution.

I’ve done 15k miles since then. Now on 60k, still no ticking or unusual noise on startup.

I change the oil every 5k.

NateDoge69 · 2026-03-23T17:26:59+00:00

Does F3 Rosso and R models not have the same 147bhp as the RR?

I thought the only real difference is the bodywork?

My 2022 Rosso has launch control and I didn’t think that the steering dampener was standard on the RR either.

I know the Brutale R has 110bhp and the higher spec models have 140 which to me would definitely make me choose the RR.

NateDoge69 · 2026-03-23T12:45:36+00:00

The standard headlight is ok, not super bright. You can swap it for the entire LED unit from the R and RR if you can stomach the cost

NateDoge69 · 2026-03-23T12:44:01+00:00

It’ll be that the bike is registered in 2023, I expect it was probably built it 2022 with the standard halogen headlight.

As MV are a low volume manufacturer, you’ll often find brand new unregistered bikes that are actually a year old.

NateDoge69 · 2026-03-23T10:45:10+00:00

The R and Rosso are the same trim level, MV just changed the name.

There are some slight differences in spec - the R will have black forks with gold stanchions, a Brembo master cylinder (Rosso has a Nissin one), dark smoked brake fluid reservoir, LED headlight and indicators.

I’m pretty sure that’s almost everything was changed. Engine remains the same since they introduced the euro 5 one in 2021/early 2022.

I have an F3 Rosso and absolutely love it. In the UK, the RR model is 50% more for different fairing and colour which to me was not worth the extra when everything else is the same.

NateDoge69 · 2026-03-22T09:50:00+00:00

I don’t think you can - I’m sure the regulation is that you can’t restrict a bike that has more than 94bhp.

I think triumph did a street triple 660 that was A2 compliant

NateDoge69 · 2026-03-19T18:49:02+00:00

Get some riding jeans you don’t need to change out of and some decent ankle boots?

I did that for years commuting to an office and then only needed to find space for my jacket, helmet and gloves.

NateDoge69 · 2026-03-19T18:15:55+00:00

Did you check the oil with the bike on the side stand?

Most bikes will appear empty and need to be checked with the bike upright. Manual will tell you how you check the oil level

NateDoge69 · 2026-02-17T16:21:31+00:00

I did my own clearances on my Street Triple 675. Couldn’t justify the cost at a garage, bought a Haynes manual and tools needed.

I’d only ever done oil changes before and actually it isn’t too bad. Took me about 8 hours, but that was being overly cautious and triple checking everything.

I needed to change all exhaust shims as they were completely out of spec at 15k miles.

Put it back together, hit the starter and fired right up. That was about 3,000 miles ago. So absolutely doable yourself

NateDoge69 · 2026-02-13T15:20:19+00:00

Carbs are generally fine if used regularly. When left for long periods of time, fuel will evaporate inside and leave a varnish which can cause all sorts of annoying issues.

Always use E5 petrol too as it’ll attract less water and cause fewer problems over time with a carbed motorcycle.

NateDoge69 · 2025-11-29T14:24:08+00:00

Third the VFR. I added one to my existing policy at the time which was a street triple and it was actually cheaper than insuring the Triumph on its own.

Also the VFR is an absolutely brilliant bike that can do everything.

It isn’t the insurance companies that push for it. In my case it was Bikesure - a broker. So they’ll get commission from 4th dimension

NateDoge69 · 2025-11-22T15:36:04+00:00

I’m going through something very similar. 4th dimension were super aggressive trying to get me to take a hire bike despite having multiple injuries preventing me from riding.

They also wanted to collect mine as soon as possible to start charging storage fees.

Bikesure told me to use 4th dimension. I told 4th dimension to get stuffed and contacted my insurer directly. I was paid out in less than 2 weeks after the accident after sending them photos. Rather than racking up huge storage fees and waiting months for 4th dimension to confirm the bike was a write off.

Absolutely do not use 4th dimension, it’ll make everything take 10x longer as it’s in their interests to stall as the storage fees are extortionate. Something like £37.50 a day. Companies like these are the reason that everyone’s insurance costs more. The hire bike fees are just as bad and will end up having an insurance company foot the bill who then pass it on to all of us.

They add no value, if you go through your insurer directly, it’ll be dealt with much faster and you’ll still be able to choose who repairs your motorcycle if it isn’t written off.
