Perhaps unknown to you! Maybe you need to get out more.

PBI has been making high quality sprockets here in the good ol' US of A for over 30 years.
Their sprockets are made here in Oregon by Pesznecker Brother Inc. PBI makes lots of other metal products in addition to sprockets.

Procycle, I know in your 525 set, you provide an EK 0 ring chain, are the sprockets PBI?

Can't get the carb settings correct? Get a portable gas analyzer. It's what I told scottbed months ago:
"From your posts, you are lost in the woods. The analyzer will light your way."



Thanks for sharing your experience.

As you see from my earlier posts, power delivery was never an issue..... but FMD.. it liked a drink. When I originally fitted the carb - jetted as it came from Procycle, but with the needle clip in the top position - I was down to 36mpg (US gallons). This was while running the stock exhaust and my air box had the snorkel removed and an additional 2" hole cut in the top.

I have great respect for all you seat-of-the-pants tuners.... but I just couldnt get it sorted on instinct alone. So.... I decided to cut the guess-work.

I bought and fitted one of these.....

..... which helped me identify where all the fuel was going. Much too rich down low.

So, to cut to the chase here's the setup I've arrived at:

Stock exhaust (ground header weld, ceramic coated header pipe).
Air box top fully opened up (yeah, I know I said I wouldnt ).
K+N filter (with foam outer filter).
145 main jet.
120 pilot jet.
Needle clip in top position.
Pilot screw 1 3/4 turns out.

5.0lt/100km - 47mpg(US) and still delivers all the grunt you'd expect from the TM40 .

I dont think I could've got this so right without the AFR gauge to quantify what was going on, and I learned a lot in the process.

As many have already said.... its the airbox which restricts the DRs. IMO the stock exhaust isnt too much of a bottle-neck, in fact with the airbox top opened up I'm pretty sure I could run a 150 main jet coz there's room to run a little richer at WOT. But I'll stick with the 145.

So, a long time coming, but finally I'm delighted with this carb.

Haha, that is what I was thinking too! As my old boss once told me, "Always cut towards your friend, not your thumb. You can always get a new friend, but..."

Thanks
I swear by RENTHAL sprockets-hard to come by here in the USA(like most decent things in life :p)
Most Jap chains are good,a nice coloured RK for cosmetic effect :)
An engineer once told me that there was only 2 chains to be used in a marine enviroment,Reynolds
was one,cant remember the other-far tougher place than on a motorcycle!
Renthals by far the best looking sprocket too-OEM's ugly ha ha!

Sprocket brands in our kits change because no single sprocket manufacturer makes enough DR650 sprockets to fill the demand all the time. Seems like 2-3 times a year we are shaking all the distributor bushes trying to find enough sprockets to keep orders moving. Most of the time front sprockets will be PBI, SunStar or JT. Most of the time rear sprockets will be JT (PBI doesn't make steel rears for the DR).

Yes, maintenance makes way more difference to chain/sprocket life than sprocket brand does.

No. Any motorcycle shop can easily get Renthal sprockets. All the major distributors carry them but Renthal doesn't make any steel rear sprockets for the DR650.

I contacted PBI about a month ago and they said they are setting up to make steel sprockets. I requested a 46T rear for the DR650, but I have no idea if they'll think that's a good size to manufacture.

One of your competitors sell PBI sprockets. TPI I believe? The reputation among mostly KLR users was not great. This back about 5 or 6 years ago. Like 5000 miles from a countershaft sprocket. Hard to know with DR riders ... not that many distance riders.

What sort of current feedback are you getting from customers on the longevity of PBI sprockets? Will they outlast OEM Suzuki sprockets?
How much are they? (15T / 42T)

Kientech sells them too. I'm running a PBI 520 CS right now, but I only have 2K on it.

And why would you want a steel one........if a Renthal spocket is good enough on a 160BHP Ducati v-twin,it's good enough for a 30 something BHP DR650?
