Cheaper just to swap the forks wouldn't it? id leave it be personally that big flappy mudguard gives the 34L its identity.

Mezo.

the part number you need for the genuine fender extender is 3TB-21521-01 still available, I bought one the other week for around £22 from webbs in peterborough.

I didnt drill the guard to fit it, just used good quality silicone sealant and held in place with clothes pegs. I know it works, had on on my honda hornet for 4 years and it never fell off.

As for overheating, dont think theres no way this would affect engine temps !

If you look at the fender, where the extention fits, you will se it most definately shield the motor a lot.

People with oilcoolers mounted around the cylinder, cut the fender down, or cut the fender open and install a mesh-screen to get windflow to the cooler for it to actually work.

The engine wont die becuase you use the extender, but you will get slightly higher oiltemps, all other things beeing equal.

Firstly an apology for being so long in responding to everyone, I just haven't had time to get round to it, as always advice is brilliant, hoping to get down to my local yamaha dealer very soon. Will take the part number with me. I think I will postpone fitting it short term until weather cools down abit but definately before it turns particularly foul. As i intend to ride the bike right through the winter, I will take it off the rode to get it preped in readyness.

Once again.

Thanks to all.

hopefully one day I will have enough knowledge to offer advice / opinions rather than just ask questions.

By the way, the XT is a brilliant winter bike. It just goes on and on, starts first time, plugs away whatever the weather. With decent sticky tyres (I use Distanzias) it sticks like glue to a wet road.

I wouldn't trade mine for the world.

After a recent off (green laning) amongst the damage was a front mudguard in several pieces. As a replacement i took one off the kx, not a perfect fit as the heat from th exhaust kinda modified it lol. I did wonder at the time though about cooling as the oem part is vented. However several weeks later i aint noticed a difference in cooling at all.

The airflow and cooling is governed by quite a few factors, Rick. You say there's a different mudguard there now, so it'd be reasonable to presume that it doesn't have exactly the same profile as your knackered one and possibly 'cuts' the air a little differently.

With regard to the vents, these will let a little more air onto the front of the engine (especially the upper part) - and then past it to the back - but it probably isn't a huge amount. I think the comparison earlier in the thread was more to do with the difference between the extender directing lots of cooling air way down the engine instead of that air passing over a much greater area of it without the extender, which may be more noticeable than without/with vents - but maybe not in these rather 'between-season' temperatures (unless things are much worse in 'olympian-medal central' [up there in Yorkshire]).

The physics speaks for itself - so there IS a difference - but you need to be comparing like for like in the other areas, in order to make a proper comparison. I also think you'll struggle to notice any significant difference whilst making 'adequate progress' through air that's well within the ambient temperature margins of 'easily enough cooling' and 'nowhere near overcooling'. When the climatic temperature gets really hot or cold then the difference may be more apparent in terms of struggling more/less to either stop the gauge-needle getting alarmingly high, or to warm the darned engine up to full operating temperature when the climate's 'raw taters'.

Hey, and welcome! (I see you're pretty new to the HUBB - I'm quite new to it, myself [Good, innit?]).

Well when ya put it like that lol ;-))

Yeh am new, thanks for the welcome,

Anyway am picking up a new mudguard tomorrow, albiet universal polysport yamaha supermoto thingimy whatsit. Hopefully a better fit. Be interesting to see if that has a noticeable affect?!?!

Does anyone have a link to stores selling these?

The real question is... how to get rid of that monstrousity that is the bonus rear fender/plate holder. Have been looking today for ways to lose that horrible lump. Has anyone modified theirs?

I saw people talking about a UFO unit but wasn't having much luck on google!

You should really make a new thread regarding the rear end, just to make it easier to find the right topics in the future. Anyhoot:

I've modified my rearend to take away that 80's look. I think it helped a lot, especially togther with smaller mirrors and blinkers, it gives the bike a much cleaner look. Oeh yeah, the rear end is raised aswell. Here's an old pic:

Hi, Jens

May I ask how you raised the rear end? Was it a different shock, jack-up kit or other?

Cheers
Nick

Jack-up kit, but several suspensionmakers also offers a longer custom shock, but they dont come cheap at all.

See this thread: http://www.horizonsunlimited.com/hub...spension-60728

Thanks again, Jens. May well give it a try.:thumbup1:
