  1. Thanks Arttu, That's kinda what I thought too, but I'm loathe to just accept something without at least making an effort to understand why something is done the way it is. Your explanation makes sense, and if you have already used 1150 trannies in 1100 engines without ill effect then I'll put my faith in your experience and just go with it.
  2. Thank you Isleoman. Yes I am a member of the GS Resources (just recently) and there is a bucket load of information regarding these older machines. Actually a really good site for those wanting to maintain their bikes. Well worth registering. Lots of info regarding the 1150 tranny in the 1100 engine but I couldn't find anything about that plug. Maybe it's of no consequence in the grand scheme of the Suzuki design engineers mind and maybe I'm just over thinking things, but I'm curious that's all. Don't want to have to make another post about a blown 1150 tranny only to have a site member go...."Oh, you should've blocked off that aluminum plug...bla bla bla"
  3. Hey all. I searched around the forum to see whether anyone else has gone this route but was unable to come across anything. If I missed it and am double posting, my apologies. So here goes. I just got hold of a pristine transmission from an 84 1150 EFE. I got it because my existing gearbox has several gears that are really in poor shape and an 1100 gearbox was nowhere to be found online. I was careful to cross check all the part numbers for the gears and despite some numbers not matching for the most part it looked like it might just work. I found only 4 things that are different on the 1150 tranny. First off the roller bearing on the drive shaft just behind the chain sprocket is 25 x 62 x 19 where-as on the 1100 it's 17. The drive shaft is also several mm longer but that's at the threaded end. The countershaft is also longer by approx 5mm but that's also at the thread. Furthermore when I looked at the end of the countershaft from the clutch side I noticed an aluminum plug with a small hole down the middle that air passes freely through. I'm guessing this is for lubrication. Other than these differences it would appear that this tranny will work fine. I did a dry mock up in my 1100E casings, swapped the 19mm deep bearing for a 17 and dropped the complete unit in place. I installed my crankshaft and clutch assembly and checked that everything rotated fine and that I could change gear. No problems discovered. So based on this I think I'm going to go ahead and keep things the way they are. I didn't see any issues with the longer threads on either the countershaft or the drive shaft. The only thing that leaves me with a question mark is that aluminum plug. The original 1100E countershaft is closed at the end. Is there anything I should be concerned about regarding this plug..? Does anyone know why Suzuki would have incorporated this in the 1150 shaft and not the 1100..? Am I ok to leave it as is or should I close it off..? Hope someone might be able to help out. Thanks in advance.
  4. Thank you very much Arttu. That's super helpful info. It does look like the camshafts I have are in fact from the 1150. Good news. I can stop looking on Eblag now. Not that there's a lot around these days.
  5. Not new to Oldskoolsuzuki, but it's been a long time since I checked these pages and I'm happy to say that like a prodigal son I have returned. A bit battered and bruised in the meantime but my motivation to finish a project I started 7 years ago has not left me. Something about an itch I think. I am the happy owner of 2 Katanas. 82 1000 SZ and an 83 1100 SD. The first bike I've had since 1986. I picked up a 750 Kat frame many moons ago and started collecting parts for a project build. I'm currently working on an 83 1100 E engine I'd like to fit in the frame. Very mild modifications consist of Wiseco performance pistons taking the engine to an 1134, some basic head work to valve seats and valves. I was looking at camshafts a long time ago but all the performance cams have got some serious lift and require rockers to be specially hardened. All adding a lot of dollars to the project. I've heard that the camshafts from an 84-85 1150 can add a bit of extra pep to the engine so was wondering about their viability..or..if anyone knows of some OEM Suzuki camshafts that would work better then I'd be open to any suggestions. I don't want to go crazy with the hp ( I know.....I'm a 58 yr old pussy ) but want to build something reliable and that won't stress the internals of an engine that's getting harder and harder to find parts for. I understand that grafting an oil cooled lump in the frame may be a cheaper and easier option but I agree with those that favor the air cooled engines for the way they lay down their power and for their sheer sexy looks. Anyway, I'm rambling and don't want to get banned on my first post. Amongst all my parts I have several camshafts whose engines I know they came from. I've got one pair I cannot place and a measurement of the cam lobe profiles rendered the following info. Intake cam lift...4.623mm and exhaust cam lift...4.927mm. I'm hoping that someone might have a Suzuki service manual for the 1150 and let me know whether I've gone and picked up some cams from this bike and have forgotten about it. Would be greatly appreciated. I know that pics are always appreciated and I promise (honest) that not only will I post pics of the project once it's completed and confirmed to be "alive" but I'd also like to share info of all the parts I've used with their specific years complete with measurements in the event that it may be of use to someone. Thanks for taking the time to wade through this post. I hope you can help me out.
