Report Please Help The New Guy. If Nothing Else You Will Get A Laugh From My Stupidity! in Sherco Posted June 15, 2015 If its the same type clutch as I have fixed on Shercos, Betas,Scorpas in the past, clean the glue up then do this very simple (hour or so) fix, finish off with my choice only Dexron ATF. Not fancy, thread file 10 or 11 pitch, 3 strokes each pad. Try not to go to deep, all we are trying to do is add radial grooves to help break up the sticktion and sling the oil out. Try it you will like it. Shaky old camera hands, sorry about that. Larry
Report Mar - Difficult Starting in OSSA Posted June 13, 2015 Remembering back to my last encounter with an Amal carb, an old way was to hold your thumb over the tell tale hole to prevent washing the engine and putting the fuel where it belongs. I have 5 Amal 627's on hand in a box on the shelf. At the present time have 1 Mk 1 MAR in the family presently (Mikuni carb of course). 1

Report Old Bultaco in Bultaco Posted June 1, 2015 Larry, there are others more knowledgeable on M 10 , but they appear to be of the taper tops that were used up thru M 85 Alpinas at least, I have used early sliders on later tubes with no problems. I only offer this as my own experience. One other word of caution M 92 and on have the knurling below what you need. Larry
Report Bultaco 199 And 199A Fiberglass Tank in Bultaco Posted May 29, 2015 · Edited May 29, 2015 by lbhbul Maybe these will be of some use in your understanding of the difference in our part of the world as the only fiberglass tanks I personally have seen used, there may be others that have seen different tanks Notice shape of top, seat juncture, and bottom shape, this style of tank from M 158 thru M191 Sherpa T,they are about 8 1/2 inches at their widest point. Hope this helps Larry

Report Bultaco 199 And 199A Fiberglass Tank in Bultaco Posted May 28, 2015 Only a guess on my part; replacement item as the early plastic tanks we have seen seemed to self destruct and were not as pleasing to the eye as was the glass tank IMHO. Larry
Report Bultaco 199 And 199A Fiberglass Tank in Bultaco Posted May 28, 2015 · Edited May 28, 2015 by lbhbul Well, I have never seen fiberglass tanks with the bottoms like older models, (flat), made for later models. that said the red tank looks OK, (don't know how wide) the blue is different and I didn't see anything like it in my search, if the seat fits it will be OK for use as long as the stops are long enough. I am sure you will find more help here. Welcome. Larry
Report What Did You Do To Your Bultaco Today? in Bultaco Posted May 27, 2015 Larry 2, it is a product that Farriers use to repair split hooves when shoeing horses. it also has many other applications IE tank repair ect. I don't believe our source ships internationally however, there may be a similar product available to you. This is a 2 part epoxy that when mixed goes off in 3 minutes, and is the consistency of water so it gets in every place, trade name Kwik Poly, you can read on the web. Very thorough cleaning required, as with other products. Larry
Report What Did You Do To Your Bultaco Today? in Bultaco Posted May 26, 2015 Larry, was wondering if you were still kicking around , good to hear from you again!! I was protecting the tank as it was already painted before I had it to line the inside with a two part epoxy to hopefully prevent damage from modern fuels, (no ethanol regardless). Had good luck during the cleaning process and subsequent lining,(no drips). Mailed it off to Texas this morning. Larry
Report What Did You Do To Your Bultaco Today? in Bultaco Posted May 24, 2015 Pretty good day yesterday, tank all clean and ready for lining Three passes and clean the threads, unmask and get out of the shop cause the fumes are getting to me, I'll add the newly refreshed seat later, turn the fans on high. Gotta get some fresh air!!! Have a nice day Larry 6

Report What Did You Do To Your Bultaco Today? in Bultaco Posted May 16, 2015 Well another fun few hours in the shop today, if you find that your clutch on your bike that you are sorting for the upcoming event seems to have an inordinate amount of drag this may be part of the problem; flat bearing This is from a 199A and( the more common one) They are different as to the lock screw location I hope this works, spot of weld , now it cant come up.

Report Twinshock Montesa Cota 200 in Montesa Posted May 14, 2015 A very worthy project you have in mind, the cost is not to be a concern. The hard starting could be as simple as a flooding carb, but is more likely electrical. Mount an automotive condenser under the tank. Cheap insurance. As for spending quality time with Dad, You only go round once!! Larry
Report Strange Clutch Damage in Gas Gas Posted May 13, 2015 Hario, Thanks and am glad to be of help. Combination plate fiber against clutch basket 1st in, ended up w/ fiber against pressure plate. A help for bleeding, from the bottom up I use a smaller pump oil can (new or really clean) w/ short length of fuel line. Just A way of bleeding. Clutch & front brake usually pretty easy, rear not so nice. For the Pampera, all good springs probably necessary. Have a nice day, BTW where are you? Larry
Report Strange Clutch Damage in Gas Gas Posted May 13, 2015 Hario, as promised my GG clutch in pieces. Combination plate 1st; fiber down, then typical assembly. Stack = 1.040 Pressure plate index as shown. Photos trump words
Report Strange Clutch Damage in Gas Gas Posted May 13, 2015 Hario, I will take my clutch apart shortly. In the mean time the springs that are not in my clutch measure 1.490 inch.. I also understand the bike is new to you so we don't know what PO may have changed. These are the junk plates that I replaced with new junk plates; helped it to be just like other brands. Larry
Report Strange Clutch Damage in Gas Gas Posted May 12, 2015 Hario, The plates do appear to be the original ones, they had a very distinct pattern and release very well as compared to the after market junk, yours do not appear to be worn, and don't know why they would slip if everything is adjusted (free travel @ the lever) no other adjustments left. I don't have access to an original @ this time but I know mine has a steel plate in first then a friction, Yes we run 4 springs , your springs may be sacked & need replaced or maybe you can get by preloading them slightly, none the less you have the best clutch plates & we are not able to get new ones anymore.

Report What Did You Do To Your Bultaco Today? in Bultaco Posted May 12, 2015 · Edited May 12, 2015 by lbhbul Bultaco 199, If you are going to use Barnett plates, there are several places on TC as to the set up. With a cable in good order & 4 springs you can have a nice 1 or 2 finger clutch if that is what your wanting. 1st plate in has to be earless unless you enjoy slipping when kicking. Stock is also fine, requires all springs. Nice bike by the way. See also" Action Shots in Bultaco." Larry 1
Report Strange Clutch Damage in Gas Gas Posted May 12, 2015 Whatever you do please take this as experience with the earlier design GG, (2001 TXT in my hands), do not use aftermarket clutch plates! Been there. You have the best clutch GG ever had IMHO, Mine has s***f*** junk and without careful attention will not release properly, not unlike some other brands. The original clutch plates you show look fine,not sure about the order as to the first plate in, Sherpa T will slip when kicking if first plate is not steel when using Barnett plates & 4 springs, several early GG in our group, all w/4 springs, running Dexron. My experience only.
Report What Did You Do To Your Bultaco Today? in Bultaco Posted May 11, 2015 Bondy , hope you ordered 3 inch or more as the tanks vary as to how wide they are when mounted. Larry

Larry very un-twisty, too harsh for my thinking, I prefer the nice soft Bultaco fork action.
