Any interest in cams?

Purty things Dubs.. hope they give you the power you were looking for. Never seen black ones before, only silver ones with polished lobes.

That is a moly lube coating that will wear off once fired

Those are some good lookin' bumpy sticks, PD! Can't wait to hear about the results.

That’s the skinny end of lobes on the intake (left hand cam).

Hope it works. It should have
no middle ground- either awesome or carnage.

After all this time we're hoping for awesome.

Im not sure who you used. If it wasn't crower, they may have been a good option as they love stuff like this. (if it goes south give them a try). if it was them, thats unusual.

as far as cams go on an otherwise stock motor, what josh is doing is absolutely great. the more in, the more out. im def excited to see this (after reading 14 pages).

on the last 4 stroke i hot rodded, which was a lowly grom, i could just eek out 80 MPH with a cam, exhaust, and a fuel controller. stock motor had under 9hp. adding a few ccs and a 4 valve head + a few other goodies, i can reliably hit 95 mph on it. why? because its fun. this is on a stock bottom end.

Im curious... has anybody tried swapping in an exhaust cam to the intake? (so you run 2 exhaust intakes)this was a popular mod on sv650s and yielded really good results. it left the exhaust cam lacking some, but retiming the cams made it work ok with dif. sprockets. but might give an easier gain.

just late night rambling. def watching with interest. keep up the good work.

I have not heard of anyone trying that on this bike, but I know people that have done it on some cars.

Visually comparing both cams sitting next to each other, to me it looks like this would work on this engine as well.

Would probably be a cheap easy way for someone to both get more power/tq and also get straight cam timing instead of the factory stagger that many seem to want.

Powerdubs, keep that cam shop a secret. I see a business opportunity for you if all this works

Just found this excellent thread. Great work PowerDubs!

My personal preference for custom grind, would be to smooth out the vibration and add more midrange torque. Then tune out the low rpm throttle twitch and adjust for 12.5-13 afr. Factory airbox and header because I want it quiet.

For anything else, it's cheaper to just buy another motorcycle.

It rips at ~3,800 up. Yesterday, heading back to the Honda dealer to order a tire, knowing that the rear would be replaced in a week or two, I feathered the clutch instead of giving it full throttle after full engagement. The rear has 10,400 miles on it, but it is still fully legal. At about 30-40 MPH (was not watching speedo) it lost full traction and mildly fishtailed.

My guess is the exhaust cam will work in the intake cam position.

Once I see what I can get out of the bike, most likely I will also put a airbox snorkel back on and the stock header. I will need to switch the O2 bung on the stock car to fit the WBO2 sensor.

Everyone keeps saying that, but there is no other motorcycle that ticks all the
boxes the CB does.
