Claudio, I don't Know why the price is different but  the 435 is better due to the fact
that the sleeve is new and as thick as new. Where the 377 is a bored out stock cylinder
making the stock cyl very thin. I have a White Bros 385 cyl on my bench with two broken
out spots on the bottom of the cyl due to the thinness of the sleeve. I have done many
435 jobs and they are all still running including my own and shipping one out to
germany tomarrow. Thumper only handles reliable stuff that means no problems for me or
my customers.

Hi,

I was thinking that I would go with a 377 or 385 bore for
3 years and then go bigger and sleeve - but stories like
this scare me.  I suppose I should jump straight to the
sleeve.

White Bros has a 441 with a 10.5:1 piston, whereas the
Thumper 435 uses a 9.5:1 (same as stock).

Does anyone know of good or bad stories with the WB 441?
Are they known to be as reliable as Thumper's 435?  Does
the higher compression piston add much power?  Should I
expect it to shorten the engine life much?

If you have a 441 and reply to this - please let me know
if you also have the White Bros all-around CAM.

Thanks...Mark

Hi mark, I had to trouble shoot a friend through an ordeal with a 441 and he went to
the 435 and has had no trouble since. As I have said in the past I have had no problems
with the 435 and I have done about 5 of them now. as for the cam issue I recommend the
megacycle over the White Bros units due to the good results that I have had with the
megacycle units and have heard of problems with the WB cams.

Hi Jesse,

Megacycle says they don't support a cam for the DR350SE.
They said a cam for the SE model controls the decompression.
They also only show a cam for DR350 through 1996 and said
they haven't addressed whether the cam will fit later models
(mine is a 98).

White Bros makes 2 cams - an all around and a competition.
Only the all around version is supported for the SE in a
model that has the decompression mechanism.  The competition
cam requires R/D springs and shorter valve guides or lifters
or something.

I was planning on getting the all around cam.  I don't think
its much of a change from stock (though I'm not sure what the
stock specs are).

Any idea which cam you heard had problems and what the
problems are?

Can I use a non-SE cam and control the decompression some
other way?

Do you know if megacycle's cam for a '96 would fit my '98?

Regards...Mark
