I am the original owner and plan on getting it running again. Stock Gearing is 11T/39T. Does anybody know how many chain links were standard? I have 97 links using an offset link with two masterlinks. I don't know what was OEM. Can anybody help? Thanks.

Everybody else just became obsolete!

I am looking to buy a new trials helmet. Are there any significant differences between a trials specific helmet and conventional open face helmets from mnufacturers such as Zamp, KBC, Arai, Bell, etc? It seems to me that in general the trials specific helmets have more sharp, angular edges instead of smoother, more rounded profiles. This appears to be a cosmetic/styling issue that could cause more damage in a crash. Trials specific helmets might also have better ventilation. I don't know if they are any lighter or offer better visibility. Any comments would be appreciated. Thanks. tightwoods

Thanks Hewson!

I'm having trouble finding a VM28 Round Slide. I'm finding 26 and 30 but no 28's. Did Mikuni stop making them?

Thanks!

No, Pennsylvania, USA

I plan on upgrading the stock 28 mm Bing T84 (the slide is badly worn and I'm told virtually impossible to replace) to a Mikuni 28 mm TM flat slide, VM 28, or VM 26 round slide. Does anyone have experience with any of these carbs on a 199A? Will the 26 mm work well or is it too small? I've been told that the smaller bore might boost low rpm performance. What jetting/needle combination works at 1500 - 2500 feet? Thanks! tightwoods
