Transalp De-restriction??

[davidstanbridge]

I've just bought a Transalp and I have had to have it restricted...

Would it be worth the risk of de-restricting it for the gain of performance?

If so how do you do it?

Is it difficult?

Thanks

David

my guess is that it's a case of getting your local dealler to plug in their magic box and update the ECU ?

No..

All I know is that it's two washers in the carb somewhere...

Thanks

someone's selling one in the "For "Sale" forum for a 650v - guess it's similar ? Note sure how it fits but just looks to restrct the air flow

It sounds like the same arrangement as on both my son's bikes (not TAs though). Basically washers in the inlet manifold (ie between carburettor and cylinder) to restrict the amount of fuel air mix reaching the cylinder. The size and to an extent the profile of the washer will dictate the amount of fuel and therefore the max power. They tend to have more effect at higher revs so a big capacity restricted bike feels more tractable at low rpm but the reduction in power is much more noticeable as revs rise. Max power on a TA650 is just under 50bhp so you have lost over 1/3rd of the power, but it will be power produced at around 6,000rpm+.

There have been lots of discussions about the legal, insurance and moral position about riding a bike without restrcted power when on a restricted licence. Do a search.

If you haven't got a restricted licence, get the restrictors out. If you have leave it in until your 2 years is up.

Getting the washers out will be carb out job, not technically difficult, but quite fiddly and you have to remove bodywork, tank, air box, battery and box, and exhaust I think. Getting the carbs out of the somewhat limited space is a bit of an art too. Its all just undoing and redoing (quite a lot of) nuts and bolts, but as I said a bit fiddly at times with the risk that there will be one or two stubborn one's that don't want to turn. DIY if you want to learn your way around the bike, otherwise you are paying a dealer/mechanic for some fairly simple work. I have done it once, took me about an hour and half to get them out, and about the same to reassemble. Spread it over a day and give it a good clean while you have the access, loob stuff you can't normally see, clean the carbs, blow out the jets, drain and refill the coolant and stuff like that and you will have had a very enjoyable day.

good luck

Thanks that's very informative and interesting...

As above, it is not worth taking the chance, A couple of members have had restrictors fitted to the Transalp and it was said not to make too much difference.
Stay legal, the Bike does not lose too much power.

[davidstanbridge]

Yes I think you are right...

The bike's acceleration does not seem to be affected, top end I think the only real difference is....

I'm going to keep it in, although now I have the certificate police in this country would probably be none the wiser...

Although my dad says I would be done for if there was a bad crash and the insurance companies started asking questions... (god forbid theres not)

Thanks

Your dad is right. You wouldn't be riding in accordance with your licence so you'd basically get six points and an instant ban with a compulsory retest if found out. That's the best case scenario. If there are injuries to a third party and it's your fault, I can't imagine your insurance company being willing to pay out.

Hi all. My 2007 tranny is restricted and it doesn't bother me in the slightest. I haven't been found wanting power. I'm not even sure when or at what revs the restrictor is supposed to kick in but I've surprised myself overtaking in 3rd with the revs well high. My dealer will take the washers out when my time is up (next July I think) for nothing. Sounds much better to me than what Austin suggests! That is not my idea of a fun day and would end up with me scratching my head with a garage full off bike parts on the floor!
There is quite an interesting article in MCN about restricted licence certificates, basically saying they aint worth the paper they're written on and it's a bit off a scam. Worth a read.
I personally wouldn't take the risk of derestricting it as you will basically be riding around uninsured. Enjoy the bike mate.
