New 2011 TE449 with JD EFI Tuner - first ride

[spud1968]

wet, chalk whoops about sums up this ride my first competition

 

[spud1968]

Riding in the winter i've noticed lots of foreign bodies getting in to the air box. This is happening due to two reasons. 1) when behind a rider who spins there back wheel the dirt etc is getting in via the intake rubber i've found stones, bits of wood and grass. I initially extended the deflector guard using duct tape located on the rad guard to increase the protection and its several layers thick . I then added some alloy wire grill to the intake rubber to stop the larger objects entering the air box. 2) Finally I put some sump guard foam over the drain holes inside the air box lid glueing it in place. This is to stop prevent the WOOSH of water entering the air box when riding through big puddles and allow the drain holes to breath air. Pictures below:

Good tips. Any more ?
Do you find that
1. the gear lever comes loose easily and is a stinker to work on
2. The bearings in the rear linkages ,without greasenipples, dry out rapidly and need greasing every 2 rides.

Great bike, still working on suspension settings to help stop front end 'pushing ' in corners and wandering whilst on shallow rutted straights.
i'm in wales by the way.

Hello twm,

I nipped my gear lever up from new, but that reminds me to check it again.

The bearing at the bottom of the shock is exposed and yes greasing is important and i've done it once and only ridden the bike 3 times. The grease nipples are difficult to get at with my old grease gun.

I've got TC449 forks and not the standard units, the rear shock has been lowered by 4mm like on the 2012 bikes and handling is sweet.

I've fitted a JD Efi tuner and will have the spark arrester removed from the akra muffler soon i'm looking for a bit more power because lifting the front wheel requires quite a bit of effort.

 

[spud1968]

I've had the Akra can derestricted removing the spark arrester. Just to be safe I had a removable insert made if I found the bike too noisey. With the insert in place its very close to the noise level of the stock Akra before the modification. With the insert removed its not that loud has a nice more crisp throttle bark response. I've not ridden the bike with my newly modified Akra. The person how modified the exhaust said we have a big lump of metal causing quite a bit of a restriction and even with the insert installed he said it would flow noticable better.....so pics below costs $30

The insert

fully deristricted and showing fixing point for insert

I guess its time to hit a dyno shop when the funds allow

Hi Spud
when you say you shortened the spring do you mean compressed it wth the lock rings?
twm

 

[spud1968]

The damper rod was shortened by 4mm.The spring is standard length.

 

[motomanic]

Hi Spud , who converted the can or you? Wasit in the London area, let us all know the difference.

 

[spud1968]

A friend did the exhaust he's a retired metal fabricator and has done work for me over the years. Yes he's located like me in the London area.

 

[spud1968]

The first few seconds of this video I wheelie the bike by blipping the throttle. This is new its never wheelied so easy before.

 

[glangston]

Yes, it's a good feature...

 

[Huskynoobee]

Boy, must be nice to be in a place where removing the spark arrestor wont get you arrested

Here in wildfire prone cali, the cops carry wire coat hangers to stick in the end to make sure its still there.

Plus you guys get a nice Akropovic while our street legal 449s get a monster muffler from a Fiat or something.

The bike is not that much more noisey with the spark arrester removed.

I've fitted some lovely red Talon X8 footrests. The perch is approx 10mm wider and they set the bike off colour coded....lol

Back to the business of POWER!....
.....I've been reading about the BMW 450X Speedbrain. This bike was designed in partnership with BMW Motorrad Motorsport in Germany. The bike came fully spec'd out with X Trig triple clamps, WP Closed Cartridge forks, WP rear shock, Saxess wheels, factory Brembo brakes, Fully Akrapovic exhaust and factory ECU. The Akra on the bike i'm reading about has a power bomb tube and not the ballon type found on FNF designed for our Huskys. With the Exhaust and ECU the claimed BHP increase gain was 5.5bhp mid range and turned the bike into a racing with better fuelling. I've fitted the JD tuner and modified AKRA, so how far out can I be from this BMW racer especially as i've fitted the TC449 forks and the rear shock has been shorten, which in the BMW Speedbrain's case the bike sits down a little at the rear unlike the standard BMW 450x and 2011 Husky 449 TE/TXC. It would appear with out my knowledge my Husky is slowly turning into a BMW Speedbrain 450.

Gearing is important my bike came with a 51 tooth rear although i fitted a 49 to see if i could spread the gear changes a little more. With the slightly taller gearing, JD EFI and derestricted AKRA exhaust can it feels more powerful/faster accelerating then when it had the 51 tooth rear. I think a power bomb is next in the shopping list but i'm undecided about the X-trig triple clamps.

Hi spud
Where did you get your sprockets from ? I need front and rear asap and chain b4 thursday at the latest. help!!

Husky Sport would be my first phone call....failing that MPS racing as i don't think they are to far away for you in Wales......they advertise on Enduro News ask for Mick.

Having not rode for a few weeks and my first ride coming in the way of another practise day on the 4th March, one week before the 2012 TBEC championship starts i've been thinking about the 449's motor and wondering like the new 2012 KTM 450 the bikes seem to stall at lowish rpm compared to carb fed bikes, so this is a theory......

......with 449's very short stroke it builds revs very quickly and with standard gearing rips into the uppr mid range like an mx bike if you've decatted the AKRA muffler and are running the JD tuner..as with most short strokes bikes if you try lengthening the gearing because the 449 does not have a high top speed on the highway it then doesn't like low revs and stalls easier than you want even with idle turned up. The end result is slipping the clutch to pull away from an idle speed of around 1800rpm standard. Imagine your stationary off road on a very slippery camber at an angle on the camber and you want to easy out the clutch at almost zero rpm. On the 449 this is almost impossible with a tick over of 1800rpm. In this situation i'd be looking for a pull away rpm of about 600-800rpm from a carb bike, so its not hard to see why if you up gear your bike why it will stall and why the bike stalls now. I think the first gear needs shortening (reduced speed) and the other gears to be spaced out a little further. I'm putting a (?) to see what you guys think of my theory and what, if anything can be done.

Moving on......i've been looking at the FMF powerbomb manifold for the above reasons to give the bike a touch more idle power and midrange so i can lift the front wheel over say 100yds of speed bumps and pull away at lower than 1800rpm idle speed. My bike is putting out more power with the JD tuner and decatted AKRA but how much i don't know apart from it wheelies under throttle which it didn't do before. I've fitted a small radiator expansion tank and have noticed that fluid is getting into the water tank meaning the bike is boiling when it gets very hot. I've taken to keeping the rads very clean of dirt for this reason.

wauw, ive spend hours and money trying to create a unique bike then you come along and copy the whole thing .. and not just a figure or 2 but a exact copy ! really??!
was it too hard to create something yourself?

not cool !

Just took my '11 449TXC out for the first real ride.

It was a nice walk home!

The shop put a tuner on her and it is possessed. Got it home Saturday night. Short ride through the fields, washed and parked out side my living room window. after a couple hours of gauking, realized the the glare on the tail lamp was too bright.

Ok... thought I might have left lights on. NO

They just come back on for no reason. After several attemps to disable, I unplugged the battery and went to bed.

Took off Sunday morning. It fired in 27 degrees, the first hit.

after a couple stalls and hard starts. (is it me are the battery?) The battery was dead at the bottom of my bottoms.

Forced battery terminal screws loose and walked home with the battery in my hand.

It's charged now and I guess I have to walk back.


Want to say that I love it. But bought it two weeks ago and the only sweat I worked up was walking up the ridge in full gear and a battery in hand.

What's worse... I know that the side stand will have failed and I bet it is laying on its side in the rocks. It can skip around with wind buffeting.

Also, Spud I am going to use your designs. I am not sure of the intake positioning. My plastic is already slidding out of place.

 

[montanaman]

Have you noticed significantly more fuel consumption with the JD kit? My 250 with stock settings seems to be thirstier by a lot. Also it made the exhaust more quiet? Power feels better and more solid.

 

[Rearwheelin]

I have read about the low rpm stalls but haven't really seen it on mine, I have chopped the throttle super fast when bike is in neutral and can never catch it of guard.... There have been a time or two when coming into a turn a gear too high And caught a stall , I think cause the clutch drags some.....
Another note, have you had any trouble blowing oil into the airbox threw the crankcase breather ? Was curious what oil your running and level shown in sight glass ... I'm thinking this issue so many of us have will go away after rings seal.... Cheers, Randy
