nigel dabster Posted February 26, 2004 Report Share Posted February 26, 2004 Dave wood is a good man in the know and his passion is ossas, I said ossa's! Posts on here as woody I think. Quote Link to comment Share on other sites More sharing options...
woody Posted February 26, 2004 Report Share Posted February 26, 2004 Correct Dabster - and they are still a passion even after its crap brakes and duff clutch cost me 6 soft marks on 2 soft sections at the Mansell on Sunday. The frustration which finally burst forth in verbal form at the penultimate section was probably heard echoing around Wenlock Edge for hours afterwards. Wish I could help with where to get an airbox for a Gripper but I had the same problem when I rebuilt a 250 and 350 couple of years ago. Both were mashed but couldn't source one anywhere, even from the states, new or used so had to improvise with them and patch them up. Chances are though any used example you locate will be next to useless as they aren't the best construction. They can break apart at the mounting points and crack open here and there. I daresay that Spain would provide one (I never tried as I can't speak Spanish) and there are several specialists on Mats Nyberg's Ossa site that you could try. There is a story that somewhere in Barcelona there is a lock-up or such where there is an Alladin's cave of Ossa stuff, spirited away from the factory in the dark days before closure but no-one seems to know where it is. One day I will make the pilgrimage to find this Holy Grail of Ossaland. If I were doing a Gripper again I'd get an airbox made from alloy and re-position the mounting lugs so that it can be removed from the bike sideways through the frame tubes - from memory it has to come out the back which means back wheel out. Memory not so good though as I've tried to erase my time working on the Gripper..... Depends whether you're bothered about originality, personally I wouldn't be as I'd rather have an airbox that I can remove easily and that won't break again. It can also be designed to take a top loaded filter such as TY/TYZ Yam or Scorpa SY which are available and make servicing easier. As I recall getting Gripper airfilters was also a problem when I had one. If you're busy modifying it, moving the footrest position down and back and replacing them with modern pegs improves the riding position a lot too in order that you stand in it a bit more rather than be tipped over the front. Depends how tall you are and whether it bothers you I guess, but I've done all my Ossas and it makes a worthwhile difference to riding position/comfort. Hope you get it sorted.

old trials fanatic Posted February 26, 2004 Author Report Share Posted February 26, 2004 Thanks for the response. I've already tried Jeff and Dave. They are both good guys but neither could help. I'm a glutton for punishment at the moment as i am also rebuilding a 340 bultaco 6 speed (almost finished) and a 349 Cota (about 75% just cycle parts to go) and Jeff has been an Aladdins cave of parts. Ossa parts however? Unfortunately not. I've heard of that mystical garage too but when i was last in Barcelona nobody there had. Then to top all that i've bought a B40, told you i was a glutton for punshment, so you will probably see quite a few postings for help and advice. Woody yes i agree i have already moved the footrests. Its good to know i was right and it looks like i will have to fabricate an airbox also. If somebody had the money, time and skill there must be a living to be made out there with Ossa bits as there's loads of bikes needing loads of bits. Problem is when i get it finished i probably wont dare ride it as i'd be unable to repair it if anything broke. One reason i bought the B40. Daft as it sounds there is a ready supply of parts for these. Only problem is how origional do you keep the bikes ? Nobody seems to be anle to tell me what is legal and what isnt. thanks again for the advice. Quote Link to comment Share on other sites More sharing options...
nigel_munday Posted February 28, 2004 Report Share Posted February 28, 2004 (edited) Let me know if any one has 350 gripper air boxes as i also have one with no air box, and need one desperately. As far as i know i have the only 350 gripper and 250 orange gripper in AUSTRALIA and need a source of parts. All the best nigel Munday.

jaylael Posted February 28, 2004 Report Share Posted February 28, 2004 Hi all you OSSA fans! Here's a link to Keith Lynas OSSA world. Providing all sorts of OSSA parts in the USA. I found this very helpful. No gripper airboxes I bet alot of other really good stuff. the address is http://hometown.aol.com/klynas/myhomepage/ Quote Link to comment Share on other sites More sharing options...
toofasttim Posted February 28, 2004 Report Share Posted February 28, 2004 'K, you could try "Classic trials" in Barcelona, they might be able to help. Alternatively, if the worst comes to the worst, scrounge an airbox off a gripper owner and give to a fibre-glass expert to copy. Shouldn't be too difficult.
