Hi,

One of the Husaberg dealers in Sweden told me if I wanted to use a 08 camshaft I also should increase the copmression.

Is it more peak power with a 53 than a 55?
Must be a reason why they use the 55 in the 501

Generally speaking if u increase the camshaft opening lift / duration u must also increase the compression ratio

If not then u will generally lose power and torque.

I have a GW G2 (little use) and G3 (no use) for sale.

£150 each.

Mikst,

What are you actually looking to achieve with the change in camshaft? Or are you just looking for information for comparison?

For what it's worth, I had to really tone down my 2001 650 for off-road and trail riding - including go for a milder cam (53) and now LX2 in order to maintain at least some driveability (this is compared to the 55, 08 and LX1 camshafts). In full tuned trim the bike was just a complete animal off-road.

Cheers,
Simon

so you're saying that you timed your 53 and 55 cam? that you used one of them std and then changed it 5d to be the other?

i doubt you could tell 5d simon!

what's your back-to-back on all these cams?

No, I had 2 different cams that I swapped out.

Hmmm, interesting, so now you're doubting what can and can't be perceived by others, yet you yourself have been singing the praises of swapping the Husaberg cams?

Cheers,
Simon

Information for comparison is good to have but I think I need to replace my camshaft. It's why I am asking about the information before I order a new one. I need good response in the low and middle register. Lot of peak power is fun to have too but you cannot get it all.

Regarding Husaberg the engine behaves different if you use a 53 or a 55 but I always mix them up. If you have too much punch in the bottom a camshaft with high peak power could be nice since then you loose torque in the bottom.

If I understand you right a LX2 is the camshaft with less peak power?
Do you get more torque at low revs with this camshaft?

what i'm saying is that you can't tell a 53 from a 55 unless you swop them around in a day or so. because it's the SAME SOHcamshaft but 5d different and as a man who has played with many a cam and it's timing i know that you can't tell-and that was road racing where i believe there are less variables.

5d is 1mm at the od of a camwheel which coincides with this con rod length change and all the different bores and strokes that husaberg use.

the 53 cam has more lift, duration and overlap than the '01' and i tested them with no other changes whatsoever. it would have been done in a day but the timing wouldn't come right.

i can't tell 'rocked' power, i can't even tell 2bhp, but i can tell 3-4 bhp and a shit load more torque!

regards

The 53 cam is a great low down / mid range cam. The power curve won't be linear though with this cam it will go up steeply and flatten off on the top, making the bike snappy off the bottom almost.

The LX2 cam is supposed to be a good enduro cam but I can't talk from experience.

Taffy,

There's no need to take it quite so seriously I'm winding you up FFS!

On tarmac, there really is no perceived difference in the 2 cams - on the dyno there is a perceptible difference albeit slight. So too is there a perceptible difference riding in marginal conditions (e.g. loose gravel) on my 650. For me the 53 felt better - and in my opinion, that's all there needs to be

Cheerio,
Simon

what i meant simon was that i had come from a mild '01' to the '53' cam and there is a huge difference. this i could feel.

i have changed the cam timing by 2-3 degrees on a RR and felt nothing (SOHC) whilst i did the same with my DOHC WR400 and 'Taff timed' it. the difference was clear.

however 5 degrees 'rocking the cam' on a SOHC and to feel the difference? well done mate and which was the better!

regards
