HI All,
Drooling over this bike at the cycleworld show. Couldnt really tell. Was wondering what kind of protection the side mount rads have if the bike tips over? The radiators are kind of expensive frame sliders.

I did do a forum search but didn't find anything addressing this.

Thanks!
Chris

I know an owner who dropped his on the RHS. The damage consisted of a big scrape on the radiator's surrounding v shaped panel, broken mounting tabs and scuff marks on the grill and a broken radiator mounting bracket. From a distance it didn't look that bad.

The only other damage was a bent rear brake lever and a big scuff mark on the clutch cover.

I thought they were mounted there so as to ensure a write off if you dropped it, so you got a new one from the insurance :rolling: :rolling:


good for drying your socks on as well

I was looking at mine a few weeks ago and I noticed that two of the bolts had been put in crooked and cross threaded. Took a bit of work but I got them straightened up.

The other thing I noticed was that the bottom section of the surrounding cowl covered up about a quarter of the surface area of the radiator. What do people think ? could this reduce the cooling due to lack of air getting through that section ? I was wondering if cutting some holes through the bottom section of the cowl might improve the effective cooling.

Here's a mocked up photo of what it might look like:

I don't think that will work very well at all Derek..........................'cause the red cross in the middle is gonna stop all the air getting through:rolling:

Derek, I have played around quite a lot with trying to improve the airflow on the rads, it’s easy to make the cooling problem worse and hard to improve it.
there's really only a problem when the bike is stationary unless the radiator surface area is increased by about 30% its not worth pursuing, the best mod made so far was the newer maps reducing the fans "on" temp, I had my sport in 38deg in Portugal last year with no overheating problems (even after a good thrash) and then hanging around at a toll for 5 minutes.

The proposed extra holes in the fairing would help airflow while the bike is stationary but will reduce airflow while the bike is moving.

Because the radiators are at 90 degrees to the airflow when the bike is moving, they rely on the pressure difference on either side of the radiator to get any natural airflow (without the fans running). The V-shaped outer cover is designed to create low pressure. Cutting holes will work against that.

:doh:

Sorry to resurrect an old thread but has anyone ever played with the size of the rads? I was looking at a VFR the other (I was very bored!) and the rads seem about a 1/3rd larger for roughly the same capacity engine

Someone commented that the cooling problem is only when stationary but that's not entirely the case - On a hot day, I can easily get the engine over the "normal" mark just tootling along in a 40mph zone. Larger rads shouldn't over-cool at speed because the thermostat would restrict flow and more water plus a larger cooling surface must be a good thing.

I just wondered if anyone had a VFR rad in their shed which they could offer up to see how much work was involved.

Pike,
The radiators on Gary Inman's Western Sahara Crossing TNT were oversized with fans on the outside! see
http://www.jamescheadle.com/
click on 'stories' then 'sand blast' for the article and photos.
Gary reckons it stayed pretty cool and that the soft-factory panniers were pretty rugged if a little small, he was dead-right about the panniers!
Cheers.

oversize radiators

Hi

I own Gary's Sahara bike, and can confirm it runs cooler than other TNT's with the larger radiators. It is currently for sale...

Aha! I always wondered how he managed to keep it cool in the sahara - I've already got the external fan mod. They're not noticeably bigger in the pics. Why they didn't address these probs over the years is a mystery. Heh ho - Thanks for the posts. I shall add it to my list of things to do

Robin,
you own the bike that inspired me to become a TNT owner!:D
can you please upload a close-up of the radiators that shows how the plastic trims are modified to allow the radiator's extra size to protrude past, if they were modified, that is!:bow:
were the radiators damaged much from Gary's many falls?
would love to have the extra radiator size for our South Australian summers.
Cheers.

I can only second that - I loved the photo of the TNT passing the dead water buffalo. Soon after that, I bought one (A TNT, not a dead water buffalo)
A close up pic of the rads would be really useful

Cheers

Pike,
you too!:rolling: great dead water-buffalo pic, with all those vultures!:bow:
that was about the same time in late 2005 that our AMCN had a mega-naked bike comparo between the SR4 Monster, Brutale, Tuono, K1200R, Speed Triple, Buell 1200 Lightning, Super Duke, MT-01, 900 Hornet, SV1000, Z1000 and TNT, which the TNT won.:clap:
the Sahara crossing inspired me and the comparo confirmed it!:bow:
Cheers.
am still smiling!:D

Robin - Thanks very much for posting that pic.

Unfortunately, it doesn't look exactly like a VFR800 rad. I don't suppose it says "Made by Honda/Suzuki/Kwak etc on it by any chance?

Otherwise, I'll have to dig out my Observers Book of Bike Radiators

Cheers, Pike

Large radiator

Hi Pike

It will be made by the people who make the standard one, I am pretty sure. Someone will know who that is. They measure 20*34cm, and have no marks on them. I do have one spare... They also extended the black cowl at the back of the radiator, but the coloured front seround is standard. I found a radiator specialist who offered to copy mine for around £250 (each). You could get them to add a few inches (a bit Second Life), but that's an expensive exercise.

A slight disadvantage is it covers the engine bolts that most crash bungs go into, so you would have to use an engine-mounted one - I think Maniac sell some.

nearley bought it a while back when was on fleabay as seemed a bargain ,but on inspection it looked nicely sand blasted and bit of sand around the wheel bearings etc ,suggested maybe he should clean the said areas .
next time i saw was recentley at harry nash .will say it looked better .wasnt the smaller rads refitted ?
whats the asking price for this hard worked pushed and dragged through the sand bargain . and will it come with all the kit that he was selling with it
Regards
Richard
