Hi,  my first post here,

don't be afraid of the draw thru system.  this is one on my 79 DOHC 750 (sorry) but would set up the same for your application.



I have put about 1K miles on this and runs great- built as a driver, not racer. limited to 7 psi- pulls like a 1400cc bike.

Let me know if you have any questions, i'd be glad to help.

Thanks  Tom

PS,  I have a 72 cb500/4 project that i am just finishing- will post a build thread on it ( 605cc/ ported/ 650 cam/ pd50b carbs)

Let me know if you have any questions- I have 30+ years in the turbo field

I have a build thread of my bike on the DOHC site.  don't know if it is OK to link it here, but can send you the link thru PM if you like.

Thanks   Tom

A question for the viewers...

Just been reading about methanol injection and some of the systems used, when the mix is feed to the carb from the header tank under boost how is the mixture fed to the carb.?
Reason I ask is back in the day we used to fit powerjets to the o.e.m. Evo cv harley carbs and some s&s carbs that were fed directly from the float bowl. Question is -is the methanol mix fed through a similar jet..? Obviously there are the 2x 5lb one way valves to regulate delivery....just wondering about delivery to the carb.

Since the MrTurbo rebuild kit had arrived a while back I'd thought I'd rebuild the B25 today



After protecting the shaft surface I ran the turbine wheel through the bead blaster to remove all the carbon build-up.



Assembling - checking shaft end plays...



Definetely a B25



And assembled after shimming the compressor wheel to set end play.





Need to make a manifold to join these two together - it's never ending....

Latest acquisition for this project, cbr1100xx roller I got for a good price.



Can anyone tell me the difference between output shafts over the years, with pictures..?
I'm sure I've read somewhere that the later shafts have a longer spline to mount the sprocket..? I'm gonna need all I can get, plus probably an offset sprocket.

Good morning Dale, the F2/3 and K8 had a 10mm longer output shaft, not too sure how easily they fit into earlier cases, different bearings. You sticking the turbo on the 1100...?

Good Morning, 1100xx front and rear ends to be swapped onto the ko frame with the 970 draw thru turbo....one-day...
similar to Ilja's turbo project.
Gathering parts slowly... Thanks for the info about the shafts, I'll have a look at my parts stash.
