Bondy, I am sure your rebuild man is experienced with Bultaco kick start mechanism to wind the KS shaft 1/2 turn before mounting the cam pawl on the spline. Have a good day Larry

Mark, coming along very nicely!! Be careful of that what appears to be a very long clutch arm, may just be the photo, but it really needs to be as straight a pull as possible. Beautiful work and attention to detail. My last M85 was just OK compared to yours. Have a good day Larry

Stuart, you really need to vent the mag case to prevent sweating, however I don't know what model you are working on?? M199 forward have a vent hose. Would also suggest an automotive condenser under the tank while your at it. Larry

Very nice Stuart you will have to be sure to keep us abreast of your projects. Today my buddy brought me a m166 Alpina cylinder (std bore ) that we shall attempt to machine to m199 dimensions as close as possible (Alp 64mm stroke). It looks like it will work. The m125 project goes on, a new surprise today; the primary case is damaged and will leak, so clean and sand and clean again, now some glass cloth and resin, should have that taken care of. New shocks arrived and installed so now all we like is finishing up! Forgot to post this photo of a m159 style glass tank and wonder if any can tell where it might have originated, please note filler. Thanks Have a nice day Larry

Getting closer got to finish this beasty, time to go fishin!! Have a good day Larry

Paul, good thinking from your friend!! We tend to get all wound up in helping and tend to not see the obvious! You count 6 eared plates? You must then have maybe 7 others? Question is irrelevant as it is now satisfactory. Fuel consumption is something , I have only experience with Sherpa T, but have seen a marked improvement when changing the Bing for another brand. Larry

We have made a little progress, need to get on with it as fishing time is close. More later Larry

Paul, I have no experience with Frontera's!! The reason I (and others) use 4 Barnett's is due to the thickness of the clutch pack, Sherpa T's clutch basket & engagement of the pressure plate on clutch hub dictates how thick the pack can be. We get by with 4 springs quite nicely, the main problem I have seen with a light clutch has been with slippage when kick starting , no slippage when going to 4th which is a big jump from 3rd in my experience. As for levers the stock Amal's are very good other brands leverage not so good . My preference only; Dexron ATF. Be sure 1st plate in; earless. Pin type require shimming as you cant match the original pack thickness, had good results on four Sherpa Ts using 4 Barnetts. Larry

Here is the latest fixer upper to come through the door, just mostly cosmetic as it was here a year ago .( Not running at the time) Carb change for you know what I like; it had all new points & condenser,( ran terrible), nice new remote auto condenser sorted it. The top of the tank in front of the filler looks like an alligator! To be continued Have a nice day Larry

Larry, glad to see your back and going again. Cant give you any help on brush painting as I gave up on that because I couldn't brush anything period!! I generally powder coat as I cant get a frame ready to paint, but if I did paint it would have to be sprayed in some manner. Good luck Larry

Dave , replacing the steel clutch in your Alpina @ the mentioned price , for me would be a no go IMHO. You only need 4 of the friction plates and these are usually available on internet @ far less. The setup for the modern plates can be worrisome with the pin clutch setup I would gather you have. (no adjustment) other than shimming. You can achieve a 1 finger clutch buy the above method & 4 springs as the 175 shouldn't be as finicky as what a 325 is, so if you want a lighter clutch, give it a go. Good luck Larry

I would think Rod is very right on the bike right down to the tape on the down tube. "Works Bultaco" speaks volumes as to the front forks . Tank & air box appear to be a sign of things to come. Good go Larry

Strange yokes,re. two clamp bolts on top, single on lower?? Alpina front end?? Cant see enough of the frame, but by the tank separate from seat & shape says (to me), M158 or later. " New bike at the time" ? Not up on what alloy tanks for European, but paint not std Bultaco. Front end mystery?? I am completely in the dark as to the rider,but I know someone will know! Derek thanks for the contribution. Larry

Due to all my messing about with pipes and whatever I needed to come up with an air box/carb hose that would get around a M92 style frame re. down tube/straight intake manifold. My good friend @ the auto parts store took the time to find this hose for me. after some cut and fit hose is Gates #20849 Have a nice day Larry

Good stuff Stuart and Tripp, and all keep them coming!! Sure wish we could of taken more photos before we got so OLD!!! Trees get in the way of the rocks. Georgia boy in Okie woods Larry

I worried that the work on the pipe went a little too well, so when the rear pipe and spark arrestor/ silencer arrived I borrowed a M92 to ensure all fit as planned. Well best laid plans usually go south (as usual for me) Didn't fit, don't know what it's for??? That's better Larry

All participation is good, I am sure there will be more as summer leaves us for better riding weather. BTW my son was the same age when your 198 was new. Larry

It most certainly is not main seals, you have cleaned the carb and as above stated. I find WD 40 or similar thru the pilot circuit will leave a clear trail into the venturi to ensure visual clear passage. If you have not added/replaced the Femsa condenser with a remote under the tank I would encourage you to do so. Many have success with that carb. Good luck

Just for talking purposes only 40 or 50 pilot, 100 main is what we have found for the Bultacos'. Maybe a starting place, I am sure there are those closer to you with more expertise.

Nicky, I have no patience with Amals , for me Mikuni , the only problem is jetting. The carbs we get from the largest supplier come std. with a 60 pilot / 190 main on the 26mm , this is very safe as I have yet to see that combination work ( way rich=safe). Hopefully Inmotion has a good jet combination. Good Luck Larry

Hello from summertime in Oklahoma. About 98 deg F. Its a little too warm for anything serious, lust a little Mikuni tuning using my son for a tester outer of Dads messing about. Seems OK, now back in the AC shop!! Larry

Well it sure cant hurt, by the way it would appear you have cornered the market on bikes. Good Luck Larry

Stuart, my best luck with seals; removal can be facilitated with a bit of heat and careful levering and soft alloy to lever against so as not to harm the slider,( I don't own a proper seal puller ). 1 seal per leg 35x47x10, I like to cut the female end of the seal spring by about 1/4 inch to ensure better sealing, (not my idea but it sure works). Good Luck Larry

Look to a new NGKbp5es, or Iridium plug , also in one instance we had a 2003 Edition where the fan motor was against the plug terminal very heavy, bike would need a new plug in 4 hours almost to the minute, gained some clearance and no more problem. Since you have two; you can have a process of elimination. Good luck Larry

Cosmo, a help would be a longer M8 bolt screwed well into the damper, then tapped with a small hammer along with some penetrating oil, should come along nicely, springs out of course. Let us know how you get on. Larry
