If I was to hazard a guess it would be...the first time it was a fluke, possibly abuse before you got the bike. Bikes do sometimes break gear teeth. The 2nd...
Well its together and drying. Shifts nice up and down... at least for now. Took me a good 4 hours of playing with it to figure it all out. The first 10...
Hey, they are tricky. A puzzle that appears to go together correctly several different ways. Took me quite a while before I could put one together right. And I...
I'm happy to report it shifted just fine through all 5 gears this afternoon. Carbs seem to be a little wonky. They don't want to idle real good. Either at...
Usually the headlight does get a bit brighter....usually it's opposite of what you describe though...it would get brighter if the battery is discharged and...
Have about 100 miles on the bike now. Still think I have some carb fine tuning to do as it tends to want to max out after warming up around 55mph in 4th....
My 1969 CD175 has low cranking compression (75-80 psig) before and after a valve job and new rings. During the leak down test indicated only 2-4 percent loss...
I think you might have some other issues. The engine should pull close to red line in 5th gear...at least 9,000 rpm. Should do it even easier with a 15 tooth...
Would be interesting to see what you could do with stock pistons and compression. I've spent about $4000 in piston R&D to come up with about 10:1+ oversize...
John, it'll go up to around 9k or so in 5th just won't stay there or like cruising there once on the move. So I'd need to drop in the rear to get closer to...
Yep...if you go smaller on one sprocket you need to go smaller on the other to keep the ratio close to the same. And vice-versa with larger, go the same way on...
CD is single carb with no provision as I remember to fit a dual carb set up so the head is either CB160 or CB175/200. I spent about $4.00 on piston research,...
C70 pistons are of course out of the questions, being WAY too small in bore and have the wrong size wrist pin. C90 pistons (50mm) bore are still 2mm smaller...
\> > CD is single carb with no provision as I remember to fit a dual carb ... The CD combustion chamber <should> be the same shape as the CB/CL 175, all three...
... The 160/175s use some oddball bearing dimensions in the upper bearing. Les Barker sells a kit of tapered bearings that includes a plastic shim for the top...
Michael, Yep, I've got a brass shim on the OD of my lower tapered bearing...AND I bought two kits to get the bearings I needed :) The shim has fallen out a...
Thanks for the great details on your race engines. Do you have a source for the copper head and base gaskets? My inclination is to tear in back down CC head...
Hi MT - The gaskets come from Copper Gaskets Unlimited in Arizona. Contact details are on the suppliers page of www.groupwracing.com (one of my horribly ...
It's not necessarily clear from that statement that I mean the sloper pistons (product code 235) go with sloper heads, and vert pistons (product code 313) go...
Michael, I've got a friend on this group ( BFD ) who turned me on to checking valve to piston by using a dial indicator and assembly with very weak valve...
... That is what I do - I use carburetor springs in place of the valve springs, assemble everything, set the lash and cam timing, then manually push the valve...
I have a great little Honda CB175 for sale. It is a 1973. It is in great shape. I have been riding it and working on it for 2 years. It only has 6000...
Just got a B bike CB175 going well enough to race. Purchased it yesterday; all wired, tuned up; stripped down. I am new to high revving bikes. This one has a...
Beth, Standard gearing for NHMS is 15/38....maybe 15/39 with a 200 lb rider and a stock bike, possible you could run 15/37 at your low weight. Stock bike in...
What part of the kick start do you need? I throw most of them away, as I do with all the other ballast the future race bikes come equipped with. But I probably...
I'm looking for the actual kick starter. I have a spring, I need the, umm, the part you actually kick to start the engine? Does that make sense? Tim, where...
I am in western Washington near Seattle. Â Go to one of the micro fische web sites and tell me which pieces you need by their part numbers. Try here: ...
Tim, Got another race on that new brake yet? JohnnyB ... as I do with all the other ballast the future race bikes come equipped with. But I probably have at...
