I was wondering if any of you guys had a better idea of the source of oil... After I ride for a decent amount of time there is oil visible on the cooling fins just below the valve cover beside the far left header. It only happens on the left ... Could this be the head gasket? It seems to me it...

You were right, a shift fork was bent at the end and it was pulling a gear too far over and was grinding on the base of the shift fork. I put in 3 new shift forks and a whole new main gear set and now its working like a charm.

well i got it back together and so far it seems to be working flawlessly! thanks again for the help....

I finally got it cracked tonight but being so late haven't had time to inspect it to much yet... I definitely see the results of the problem but haven't found the cause yet. My next question is what all should I replace? all new shift forks? shift fork drum? and the gear that is ground down on...

haha man thanks for that pointer! I actually coincidentally bought a tube of RTV silicone today but luckily now that I know, i will dodge that bullet and buy some prober silicone... and will do, im going to start that project this coming weekend and probably will run into a question or two, so...

this is the best news Iv'e heard all day! Ill have to buy a honda shop manual, the only thing my clymer manual shows is going through the top (during a complete teardown) thanks again for your help!!!

Is there a way to inspect/have access to the shifting forks without taking the motor off? (I coudn't tell from my clymer manual but (like through the oil pan)) ive worked on a bike before where you could but this is my first time messing with a cb750

Thanks for the help and yes I moved the shifter arm for the picture, so yeah the more I think about it, thats what I have concluded as well. One last thing do you think think it would be cheaper to find a different, running motor with a working transmission or paying an honest, average speed...

here is a few more pictures with the gear shift side plate off. I added arrows so you could see the play in the "gear shift positive stopper" there was also a slight amount of play in the gear shift side plate as well but not as much. Also I dont know enough about how this mechanism works but...

hmmmm not sure why the video link didn't work, Today i am going to try to tighten the detent so there is no play at all. Ill let you know what happens, and changing the oil may not have been the culprit it may have already been loose and trying to drive it after the oil change just tipped the...

thanks, I attatched a photo and a video of me wiggling that piece so you can see if that amount of play is normal

I just did your test and I think it is the detent because it pops out of every gear equally and some times it doesn't actually pop out of gear will just randomly start to grind and then spontaneously correct itself. Does the detent require the case to be cracked in order to be inspected/replaced?

@cyclebuster, could the shift fork be fixed or diagnosed without having to crack the engine case? would a good place to start the diagnoses process be ordering a new set of clutch plates and change those by the book?

I recently changed the oil and now am having some issues... whenever I put the bike in neutral with the engine running I can hear a clicking noise like a gear is barely engaged. when the motor is running, in neutral, and the bike is up on the center stand, the rear wheel turns slowly and...

ooo gotcha! thanks!

I had an idea for the site but then again maybe im the only inexperienced person on here. I wish this site could somehow incorporate some video tutorials. When one of you competent CB750 mechanic guru's needed to do some maintenance or any other project on your bike you could set up your...

Ordered!!! Thanks alot guys for your help. Its always good news when there is a simple fix. cyclebuster, excuse my ignorance but what do you mean by this? also is there any rule about where the T should be installed? ex: as close to the petcock as possible? or does that not matter so much...

hey Ive run into some trouble while trying to hook up my fuel lines. Hopefully this question hasn't been addressed before but I couldn't seem to find it. My tank's (which ive concluded must be from a 1976) petcock is on the left side and is made for one hose to plug in. The problem is my K2...

Count me in

maybe this time! im in

im in thanks!

Sorry for uploading so many photos but heres one more with the tank on!

I think I may have an extra one lying around! ill check tomorrow!

I bought a latch but I still need hinges and pins! The guy that sold me the bar latch threw in a pair of hinges as well but they do not fit my frame. these are the hinges he sent me. If anyone would be willing to do a trade I would throw in some cash too!

I really like the burnt look of this bike, it was built by Dustin Kott. I actually met him this summer and he is an extremely cool dude! http://www.kottmotorcycles.com/Kott_Motorcycles/Home.html

I don't know if these dimensions will help or not but you can find this style for dirt cheap on ebay and/or craigslist and my guess would be you could modify a bracket or two for a possible fit.

im in! thanks for doing this!

The tank is finally finished!! I like the gloss black!! Even though the dents aren't perfect I still don't regret the hammering
